What it consists of
It is simpler to develop a solution when sand concrete M300 is used. In contrast to cement, the material compacts less and holds its strength for an extended period of time.
- cement (cement M500, 400 or 300);
- crushed stone chips (up to 5 mm);
- fractionated sand;
- fractionated sand;
- granite screenings.
While the quantity of ingredients varies depending on the manufacturer, sand concrete M300 typically has the same mix and ratios. To give the mixture the desired properties, additives are added. It is possible to add plasticizers, hydrophobic agents, and antifreeze agents to the mixture. Fiber is added if needed.
- crumbs or screenings 4-8 mm in size;
- medium-grained sand 0.8-2 mm.
Advantages and disadvantages
The maximum weight (kg) that the screed can support per square meter is indicated by the material grade. The M300 is very robust, but it’s crucial to consider the application’s features.
Buyers trust concrete mix with sand content.
- Dry mix sand concrete M300 is sold ready-made, it remains only to add the required amount of water. Consumption per 1 m2 of screed is indicated by the manufacturer in the instructions.
- Fast hardening.
- Low water permeability.
- High strength, frost and wear resistance of hardened bases.
- Suitable for indoor and outdoor work.
- Environmental friendliness.
- Resistance to mechanical impact.
- Plasticity (ability to easily take the desired shape), not afraid of corrosion.
- Good adhesion to different materials.
At 0.9% moisture content, the material has reached its maximum strength and hardness.
- As a result of increasing material consumption, the cost of the base increases. This becomes unprofitable (compared to buying cement and sand). At the same time, to prepare the mixture with your own hands, you do not need special knowledge and skills.
- High thermal conductivity.
- Inconvenient packaging (40 or 50 kg bags), if you need to make a screed in a small room (4-6 m²).
- Low vapor permeability (therefore not suitable for building walls).
The layer thickness is necessary to determine how long sand concrete M300 dries. After 28 days, weeds become dry. The layer thickness directly affects how long it takes the material to reach its maximum strength (1 cm hardens in 7 days).
Composition, proportions
Average sand-to-cement ratio:
- 1/3 part cement;
- 2/3 parts sand.
The proportions in the composition of the sand concrete M300 cannot be broken; otherwise, the solution is not fit for use. The material acquires the required performance indicators and strength as a result of its universal composition.
- river sand fractions (up to 3 mm);
- Portland cement (usually M400, M500);
- fractions of coarse sand (from 0.5 to 3 mm).
Apart from the primary components, the mixture could also consist of:
- crumbs or granite screenings;
- plasticizers;
- additives to improve the technological and functional properties of the product.
The following ratios of sand concrete M300 to one ton of dry mix:
- Portland cement 200-230 kg (20-23%);
- other components — about 800 kg (80%).
Every manufacturer uses a different recipe, and the quantity of ingredients and additives varies.
Characteristics
The technical specifications of ready-made dry mixes may also vary based on GOST.
— a sign that the substance can withstand repeated freezing and thawing without losing its strength properties. Frost resistance for the M300 grade mixture must be at least 50 cycles. This kind of material can be used in garages and other unheated spaces.
A measure of strength under the influence of both static and dynamic loads is called compressive strength. The structure may deform or even collapse as a result of surpassing the indication. The indication for sand concrete M300 is 300 kg/cm³.
Construction should be done between +5 °C and +25 °C in the ambient temperature. Occasionally, the rule is broken. The material can function at temperatures as low as -15 °C when frost-resistant additives are added (without loss of quality).
At 4 kg/cm², this material establishes a robust bond with the base layer. Although the indicator is high, you should prepare the base before applying the solution to increase adhesion.
Bulk density is a measure of an uncompacted material’s density that accounts for the volume of the particles and the space that separates them. The indicator for sand concrete M300 is 1500 kg/m³.
The amount of sand in the mixture varies, which impacts the solution’s applicability:
- less than 2 mm is suitable for sealing joints, plastering;
- from 2 to 2.2 mm – for making screeds;
- more than 2.2 mm — when constructing foundations, bases.
A typical metric that indicates how much material is needed to create a layer that is one centimeter thick is mixture consumption. The indicator for the M300 grade mixture varies from 17 to 30 kg/m², depending on the manufacturer.
Stratification: a measure of the cohesiveness of the solution’s upper and lower regions. This material’s indicator, which is a standard GOST indicator, does not go above 5%.
One crucial feature of the sand concrete M300 is its specific gravity. The amount of sand in the mixture has an impact on this parameter; the more sand, the lower the indicator. This value needs to be considered when figuring out how much of the mixture is consumed.
The mixture should have a gray color, and the finished solution can be used for two to three hours. Hardening time (full): 28 days; standard: 1 day.
Production technology
Factory production produces the mixture. The process starts with designing the sand-cement mixture’s composition. The quantitative composition of the elements is given a lot of attention because altering the proportions will alter the product’s properties.
The product’s ingredients are combined in accordance with the current project. The future solution’s properties are computed beforehand.
- Weighing the components (or volumetric measuring).
- Placing the ingredients in a concrete mixing device with forced mixing to obtain a homogeneous mixture of elements that differ in viscosity and rigidity.
- The mixing process continues until a homogeneous state is formed.
- Packaging the finished product.
The density, viscosity, and other physical characteristics of sand concrete M300 remain unchanged if the technology and transportation regulations are followed.
Instructions for use
It is important to carefully read the usage instructions before selecting Sand Concrete M300 for construction work. In the event that it was unavailable, you ought to heed the advice of experts:
- to mix the solution, use water at a temperature of +18°C to +20°C;
- the proportions of dry matter and water are affected by the composition of the material, so it is necessary to follow the manufacturer"s recommendations (usually 1.7 liters of water are required for every 10 kg of dry matter);
- pour the dry mixture into a container filled with water, constantly stirring (until the lumps completely disappear) with a drill with a special attachment;
- the resulting mass must have high plasticity;
- before use, the solution must be allowed to brew (5-10 minutes);
- the solution should be laid at a temperature of +5°C to +25°C (a solution with frost-resistant additives can be used at temperatures up to -15°C);
- to improve adhesion, the base must first be cleaned and prepared (remove deformations, small cracks);
- the finished solution must be used within 2-3 hours;
- joints adjacent to structures must be reinforced, and the finished solution must be compacted;
- hardening occurs after 1 day, maximum strength – after 28 days.
A common and long-lasting material in construction, M300 sand concrete is used for structural elements, floor screeds, and building foundations. For the right strength and consistency, a precise mixture of cement, sand, gravel, and water is usually used in its composition. For every cubic meter of M300 concrete, you will typically need 300 kg of cement. Excellent technical qualities, such as high compressive strength and good weather resistance, make this type of concrete a dependable option for both residential and commercial projects.
Consumption per 1 m² of screed
You must ascertain consumption in order to buy the necessary quantity of building materials. There is a method for calculating the consumption of sand concrete M300 on the packaging that comes with the mixture. The amount of material needed for a 1 m2 screed with a 10 mm thickness is specified by the manufacturer. The indicator most frequently oscillates between 20 and 24 kg. Approximately 1.7 tons of mixture (30 packages of 50 kg) will be needed for 1 m3.
It is necessary to determine the thickness of screed in order to smooth out any protrusions and differences on the floor surface.
Consideration must be given to the screed’s height. Because the surface is uneven, measure the portion that protrudes the most and determine by what height value it is greater than other selected points in order to determine the average thickness.
Double the largest deviation is used to get the average consumption. The seams’ filling should be considered as well. The calculation is easy if the uneven floor is not taken into consideration.
During construction, various tasks are frequently completed in addition to screeds. The amount of concrete used depends on the nature of the work; in masonry, the mixture consumption rates serve as a guide.
