It is easy to handle and transport because it comes in handy bags. Due to its high density, specific gravity, and strict grading standards compliance, this cement is well-known for ensuring reliable quality and performance. Portland cement M500 offers consistent outcomes for slabs, foundations, and other concrete structures, supporting durable and robust building.

Application

For the most part, M500 cement is utilized in construction and repair projects. We are able to ensure the highest level of strength, dependability, and longevity of different structures thanks to its features and parameters.

• Creation of monolithic foundations, columns, slabs with reinforcement.
• Mixing various mortars – for plaster, brick and block laying.
• Road, railway construction, bridge construction.
• Creation of runways in airfield conditions.
• Structures with special requirements – in areas with high groundwater levels, with the need for rapid hardening.
• Installation of power lines.

The substance is thought to be universal; the solution’s chosen proportions determine this. Depending on the type of mortar, the ratio of cement to sand can vary: for extremely sturdy constructions, it can be 1:2, for masonry mortars, it can be 1:4, and for other mortars, it can be 1:5. Enough water is added to the solution to get a consistency that makes working with it comfortable.

Composition

The components used in the composition and adherence to the preparation technique have a major influence on the properties of M500 cement. Slaked lime and clay are combined to create clinker, which is then mixed with different additives like gypsum or potassium sulfate to create Portland cement.

The following are added to M500 cement as additives, ranging in percentage from higher to lower: magnesium, potassium, aluminum and iron oxides, and calcium and silicon oxides.

The cement’s constituent clay rocks are completely safe for the environment, resilient to harsh outdoor conditions, and unafraid of corrosion. Additives such as plasticizers and other substances can be added to the mixture to enhance specific qualities.

Production

The same method is used to produce Cement 500 as it is for all other Portland cement. Clinker is first created in the plant by sintering clay and limestone. Subsequently, gypsum and clinker are combined and finely ground at the same time. Finally, the composition can be strengthened, resistant to moisture, frost-resistant, etc. by adding different active additives.

The resulting mixtures are ready to be mixed with water, offer ease of use, and ensure that the GOST-specified regulatory parameters are met. Additives are designated M500 D20 (or more, depending on the volume of substances added to the composition) in cement; cement without additives is marked M500 D0.

Specifications

Grade M500 cement exhibits excellent performance qualities. The mixture’s strength, dependability, durability, and adaptability have made it extremely well-liked.

• Start of setting – 45 minutes after mixing
• Complete hardening and strength gain – within 28 days
• Frost resistance – about 70 freeze/thaw cycles
• Bending load – up to 6.3 MPa (63 atmospheres)
• Grinding fineness is 92%
• Hygroscopic expansion – maximum 10 millimeters
• Compressive strength – 59.9 MPa (591 atmospheres)
• Shelf life of the dry mix – in the original packaging, undamaged, about 1 year (despite the fact that the expiration date of M500 cement is usually indicated on the packages as 12 months, after 3-6 months it gradually loses its properties)
• Radioactivity – up to 370 BK/kg (class 1)
• Density – up to 3200 kg/m3

Density

Density is an informative metric that determines the binder’s quality. The dependability and strength of the hardened stone are determined by its density. The monolith will absorb water, collapse in a frost, and withstand different loads less well the higher the bulk density of Portland cement (PC) 500.

M500 cement has a bulk density that ranges from 1100 to 1600 kg/m3. Typically, 1300 kg/m3 is used as the indicator in the calculations. The material has a true density of 3200 kg/m3.

Additives

Portland 500 cement is mixed with a variety of additives intended to enhance specific qualities or carry out other functions.

• To regulate the properties – affect the strength, setting timelines, plasticity, water absorption.
• Material – affect the passage of hydration and hardening processes. It can be active mineral additives or fillers.
• Technological – affect the grinding process, which can in a certain way affect the characteristics of the material, but not necessarily.

Variations in the volume of additives can cause the marking to be visible. D0 is an additive-free cement; D5 or D20, on the other hand, are cements that contain 5% and 20% of various substances, respectively. In one way or another, every additive is intended to enhance the properties of the astringent.

Consumption rates

Bags containing 25 kg and 50 kg of Portland cement M500 are available (more in demand). Furthermore, all craftsmen must consider the issue of how much binder is required to prepare the solution. The type of concrete and the purpose for which it must be prepared determine the consumption rates. Cement and sand are combined in 1:3, 1:2 ratios to create plastering and masonry mixtures.

For pouring and constructing long-lasting structures, the following materials are typically utilized: clean sand (free of silt, clay, debris, and small crushed stone), crushed stone with a minimum strength of M1000 and frost resistance of F-65, and Portland cement M500.

• Concrete M200 – 250 kilograms
• M250 – 300 kilograms
• M300 – 350 kilograms
• M350 – 400 kilograms
• M400 – 450 kilograms

Concrete with a strength of M300 and higher grades is nearly impossible to prepare at home since it needs to be thoroughly mixed, which is very challenging to accomplish without the use of technological equipment.

Packing and packaging

Any quantity of cement can be produced and supplied. M500 is typically packaged in 25, 50 kg bags (though occasionally 40 kg is available). Following manufacturing, the cement is put into sealed towers equipped with a strong ventilation system and low air humidity levels. The binder is kept here for a maximum of fourteen days.

Next, paper bags containing Portland cement are filled. A bag’s gross weight cannot exceed 51 kilograms. To stop moisture from getting into the powder, the bags need to be constructed with multiple layers of polyethylene. On the container are the main designations that provide information about the material, along with the packaging date and marking.

M500 should only be kept for a few months in the factory container while it is being produced. When storing for an extended period, the bags are arranged on specialized pallets and rotated every two months.

Normal humidity levels and air temperatures up to +50 degrees are ideal for storage. Cement takes up moisture from the air when it comes into contact with it, diminishing its qualities. Fresh cement yields the best quality solution because the binder loses its parameters every few months.

Marking

All of the pertinent information regarding the binder needs to be listed on the bag, regardless of whether you purchase M500 cement in 40, 25, or 50 kg bags. GOST 10178-85 prescribes marking. The brand and volume of additives (Eurocement M500 D0 or D20, for example) must be indicated.

• B – quick-hardening cement
• PC (ShPC) – Portland cement (or slag Portland cement)
• N – compliance of the composition with GOST standards
• PL – plasticized cement with a high level of frost resistance

Another GOST, number 31108-2003, was adopted on September 1, 2004. It was superseded by number 31108-2016 in December 2017.

• CEM I – Portland cement
• CEM II – PC with mineral additives
• CEM III – slag Portland cement
• CEM IV – pozzolanic cement
• CEM V – composite Portland cement

GOST 24640-91 governs the type and volume of additives that can be added to binders.

Differences between M500 with additives and pure material

Cement grade 500 may be supplied with certain additives included in it, or it may not. Therefore, 20% of the mixture in D20 differs from D0 in that it contains additives that modify the properties and characteristics of both hardened concrete and cement in a particular way.

Because Cement M500 D0 is made exclusively of clinker and gypsum, it sets quickly, has a maximum service life, and can be used to fill reinforced concrete structures with a high degree of frost and water resistance. Additives-free cement ensures a long service life by preventing corrosion and deformation, even in conditions of continuous high humidity.

The aforementioned benefits have made cement M500 without additives very popular in both residential and commercial construction, where it is used to build roads, bridges, airfield surfaces, transmission line supports, and other significant structures.

The M500 D20 cement has a 75–80% clinker content, which lowers the astringent’s price. Because of the mineral additives, it grabs a bit quicker. Although the overall properties of the cement with additives are somewhat diminished, the strength remains unaffected.

Portland cement combined with additives is most frequently used to make building and repair solutions. Bulk flooring, robust masonry solutions, and facade plasters are all made of cement with additives, which is less expensive and more comfortable to work with while still performing all of its designated tasks flawlessly.

The White Chase M500 is frequently used to produce colored solutions; in this instance, additives are added in addition to pigments.

Preparation of concrete solution

You must be aware of certain factors in order to prepare a concrete solution in accordance with the tables: the weight of one meter three of cement, the ratio of other ingredients, the volume of the mixture that you want, etc.D. However, there is an easier way to go about it: measure out each component by volume (using a bucket, for example).

The type of solution being prepared and its intended use directly influence the ratios of the constituent parts and the selection of fillers. A variety of structures can be poured using the durable concrete proportions and tips listed below.

• Sand – it is better to take quarry sand, be sure to sift it.
• Large filler – crushed granite or crushed gravel of 5-20 millimeter fractions will do. If a foundation is being poured, it is better to take up to 40 millimeters. Lightweight concrete is created from slag, expanded clay, and other porous fillers. Lean concrete is mixed without fillers.
• Additives, additives – may be included in the composition as needed. When adding them, be sure to take into account the bulk density of cement and other components – if there are a lot of additives, the properties may deteriorate.
• Tools for preparing concrete – a large trough, buckets, shovel, sieve, hammer, trowel.
• Before diluting M500 cement, you need to thoroughly mix all dry ingredients. Water is added only after obtaining a homogeneous dry mass, preferably in portions, until the mixture reaches the desired consistency.

Make a classic mix of one part cement, one-and-a-half sand, and three-and-a-half filler to get an average concrete solution. One kilogram of dry mixture requires 1.5 to 2 liters of water, which is the equivalent of half the volume of cement. Since everything is calculated by volume, it is not required to know the specific gravity or density of M500 cement in this case.

Portland cement M500 in particular stands out for its exceptional qualities and construction versatility. It is a preferred material for a variety of construction projects, from large-scale infrastructures to residential homes, due to its exceptional strength and durability. With a compressive strength of 500 kg/cm², the M500 grade guarantees sturdy and long-lasting constructions.

A crucial feature of M500 cement is its density, which normally falls between 3.1 and 3.2 g/cm³. This density gives stability and resistance to deterioration, which improves the cement’s overall performance. The relative density of M500 cement in relation to water is indicated by its specific gravity, which is typically 3.15, underscoring its sturdy and dependable characteristics.

Practically speaking, employing M500 cement in building projects guarantees that the finished structures will be sturdy and able to withstand a range of environmental factors. Because of its consistency and dependability, it is a standard material in the construction industry, guaranteeing that projects adhere to strict safety and durability guidelines. M500 cement is a reliable option for constructing columns, foundations, and other important parts.

For builders and engineers, Portland cement M500 in bags offers an exceptional combination of strength, density, and specific gravity, making it a highly recommended option. Its attributes facilitate the construction of sturdy, long-lasting structures of superior quality.
