Concrete acts as one of the indispensable building materials. You can’t do without it in the repair and construction of buildings. The cost of the solution will depend on the amount and type of components included in it. Concrete mixtures today are offered in a large assortment, different brands have certain properties.
Concrete M150 has found its wide application in the manufacture of reinforced concrete products. It is used in cases where the structure during operation is not subjected to large loads. The material has a low cost and excellent characteristics, which allowed him to gain popularity among other brands.
Specifications
The described concrete brand refers to light mixtures. It has an average level of strength and belongs to the class in the range from 10 to 12. The density of the material is approximately equal to 2200 kg / m 3 . This value may vary slightly depending on the coarse aggregate.
There is another characteristic - mobility. Concrete M150 has mobility within p1-p4. This parameter depends on how much water was added during the manufacture of the solution. As for frost resistance, in this case it is equal to f50. Due to the low level of resistance to frost, concrete is not allowed to be used in those places where it will be affected by an aggressive external environment, otherwise the material will quickly lose its properties and collapse.
Concrete M150 has a water resistance level within w2. This indicates that the construction of this material has a rather impressive degree of moisture absorption. Therefore, the design needs an additional layer of waterproofing. Such concrete is preferred for many reasons. One of them is the fact that the material occupies an intermediate position between the brands of M-100 and M-200 solutions. It costs a little more than the M-100, but much cheaper than the M-200.
Composition and proportions
Concrete M150 (GOST 7473-94) has a specific composition. For example, cement is added in a volume of 11% of the total mass. Portland cement I-II 32.5 is used for mixing. But to use its high brands does not make sense, since consumption will be reduced. As for sand, the most commonly used material with a fraction in the range from 1.5 to 2 mm. The aggregate is well cleaned and washed.
Limestone or gravel is used as a coarse aggregate. Crushed stone particles usually have sizes ranging from 5 to 20 mm. If you clean this component from dirt, then the quality of the concrete mortar will be improved. Water should also be freed from biological and chemical additives. In order to give moisture and frost resistance to concrete, special additives are used, as well as to improve strength.
Manufacturing Features
Concrete M150, the characteristics of which were mentioned above, is made by special technology. To do this, it is most effective to use a concrete mixer. The inner surface of the tank is wetted to prevent the formation of large amounts of dust during kneading. It is important to observe the correct ratio of ingredients, load crushed stone, sand and water. As soon as everything mixes well, you need to add the necessary amount of water to the composition.
Conclusion
Concrete M150 can be prepared according to one of several technologies. Among others, it is worth highlighting the methodology, which involves the combination of sand with cement. These ingredients mix well. In the next step, water and related additives are added. If you want to extend the life of the concrete mixer, then this technology should be applied, because in this case the load on the unit will be much less.
