Concrete M350

A popular option in construction, concrete M350 is renowned for its strength and adaptability. Because it is strong and can support large weights, this kind of concrete is frequently used to build slabs, beams, and foundations. It is a favorite among engineers and builders because it provides a good balance between price and functionality.

Concrete M350 is unique because of its precise composition, which consists of a precisely balanced mixture of water, sand, gravel, and cement. After 28 days of curing, this mixture is supposed to reach a compressive strength of 350 kg/cm². Because of its strength, it can be used for both commercial and residential projects and will continue to function dependably over time.

Concrete M350 is commended for its workability as well as its strength. Its ease of pouring and shaping is essential for producing intricate architectural details and intricate structures. This concrete’s adaptability makes it a preferred material for a variety of uses, from straightforward walkways to substantial industrial structures.

Composition and proportions of the mixture

M350 concrete is one of the premium classes of building mixes. It is designed for use in the construction of structures with significant mechanical, atmospheric, and physical loads. Compression strength characteristics are particularly high. In many respects, the mixture’s appropriately chosen composition is what gives it such excellent qualities.

Cement, water, crushed stone, sand, anti-freeze, and plasticizing additives are the ingredients of F100 concrete. Strength indicators, grain size, and other critical characteristics vary amongst ingredients.

1. It is allowed to use sand with any grain size: large, small and medium.
2. It is possible to use crushed stone or gravel of granite or limestone origin.

The high Portland cement content in the B25 solution’s composition ensures that it will harden quickly. Portland cement yields commodity concrete M350, which is at least as good as M400. The amount of filler needed for 10 kg of mixture is 15 kg of sand and 31 kg of crushed stone. If cement grade M500 is available, there will be 19 kg of sand and 36 kg of crushed stone for every 10 kg of dry mixture.

When changing volume measurements from mass units:

• per 10,000 cm3. concrete B20 from cement M400 you should take 14 liters of sand and 28 liters of crushed stone;
• for 10,000 cm cube. Concrete F100 from the cement brand M500 requires a consumption of 19 liters of sand and 36 liters of gravel.

In order to determine the mass proportions for a 1 m3 volume, you will need:

• 400 kg of the 500th cement;
• 752 kg of purified sand;
• 1000 kg of gravel or gravel;
• 175 liters of water.

You can determine the proportion of what a mixture of B25 will yield. The uniformity of the mass depends on how closely the ingredients are mixed and how strictly they are adhered to. The finished concrete mass’s strength will decrease unfavorably if the requirements aren’t met, which will lower the built structure’s operational and technical indicators.

Advantages

There are many benefits associated with this brand:

1. High strength qualities within 327 kgf per cm. allow the material to confront maximum loads.
2. High mobility P2-P4 is regulated by plasticizers, so this value can reach even greater indicators. The most widely used category is P3.
3. Adjustable frost resistance in a wide range from F50 to F200. Thanks to this parameter, it is possible to achieve the structural integrity of the erected structure for the entire service life in difficult conditions caused by sudden temperature fluctuations.
4. Building materials of water resistance class W2-W8, significantly expands the possibilities of using the material. This property provides a high degree of protection against water absorption. With maximum water resistance, materials receive a structure without cavities or air bubbles.
5. Increased resistance to compression allows 1 cm sq. of material to withstand pressure up to 8 kg.
6. Product m350 is resistant to abrasion and resistance to aggressive environments.
7. High density of 1800-2500 kg/m3 guarantees the reliability of structures. Categories with a bulk density of about 2200-2400 kg/m3 are more often used.
8. Environmental friendliness and durability.

Disadvantages

Grade M350 c25 B27 is a versatile and elite material, but it has certain technical drawbacks.

1. High fluidity due to the use of plasticizers that increase mobility to P3, which narrows the scope of application of this brand.
2. Due to the large amount of cement, ready-mixed concrete B25 quickly thickens and hardens, so its rapid delivery to the construction site is required.
3. The cost of 1 m3 of concrete of this category is high, which, together with the cost of delivery, increases the cost of the finished structure.

Application areas

Maximum moisture and frost resistance, strength B27, and maximum strength concrete m350 s20 F200 is meant to be used in the construction of airfield slabs, hollow-core slabs, and other extremely heavy-duty structures.

The concrete class varies greatly in the use of additives. Concrete can therefore always be chosen based on the specifications for a different phase of the building process. For instance, in monolithic construction, concrete grades C20 and C25 are utilized to fill in the slab foundations of multistory buildings and to arrange the ceiling, columns, and beams. The majority of residential, public, and commercial buildings are constructed using materials of this grade.

The M350 W6 B20 C25 mixture grades fall into the heavy category. The building materials are appropriate for building cottages, significant reinforced concrete structures, spans and stairs, septic tank and sewer wells, and other items that can withstand high tensile pressures.

Concrete W6 – W8 is used to construct airfield slabs and concrete pavement because of its high water resistance, which enables it to withstand atmospheric phenomena and the effects of subterranean, melt water.

Preparation of the solution

It is crucial to prepare the concrete solution precisely as instructed by the technology, in addition to closely adhering to the proportion. It is advised to use a concrete mixer to create the mixture because it contributes to high homogeneity:

1. Dry sand and cement are loaded into the concrete mixer. The ingredients are thoroughly mixed.
2. Water is mixed into the composition. If a plasticizer and other additives are used, they are first diluted in water, only then the liquid is added to the sand-cement mass.
3. Gravel or crushed stone soaked in water is added to the resulting solution. Mixing occurs until the mass is completely homogeneous.

It should be noted that pouring concrete grade M350 B20 requires quick drying times due to its rapid setting and hardening.

You always have the option to buy ready-made concrete of class 350 from specialized construction companies rather than mixing the mixture yourself. In this instance, the solution will come at a higher cost, but its quality will be assured. When the concrete mass is being prepared and transported to the construction site, there will be a chance to save money and time. For large-scale projects, concrete supply companies typically offer specialized equipment to make pouring and transportation easier.

Making the ready-made mixture is as easy as mixing the pre-made sand concrete with the water amount that the manufacturer specifies on the package.
