Total weight of concrete ingredients = 50+115+209+27.5 = 401.5 say 400 kg. Density of concrete = 2400 kg/cum. So, 1 bag of cement produces = 400/2400 = 0.167 cum. No. of bags required for 01 cum of concrete = 1/0.167 = 5.98 bags ~ 6 bags. From above, if the concrete mix is 1:2:4, to get a cubic meter of concrete we require. 1.Cement = 6 bags ...

Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate.

Under 25%, 50% and of MoT replacement ratio, the elastic modulus of MoTC decreases by 0.4%, 1.2% and 1.4% for C40-grade concrete respectively while those reductions are 0.5%, 0.5% and 0.8% for C50-grade concrete respectively.The elastic modulus of concrete is also correlative with the compressive strength of concrete, as expressed by Eq.

The Minimum grade of concrete for Plain Cement Concrete (PCC) is M15. The Minimum grade of concrete for Reinforced Cement Concrete (RCC) is M20. Concrete Grade and Mix Ratio Table. As per IS 456:2000, the grades less than M20 should not be used in RCC works. Group: Concrete Grade:

Portland cement is the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-specialty grout.It was developed from other types of hydraulic lime in England in the early 19th century by Joseph Aspdin, and usually originates from limestone.It is a fine powder, produced by heating limestone and clay minerals in a kiln to form clinker ...

1, meet the strength grade of concrete design. 2, meet the concrete peaceability. 3, meet the durability of the use of concrete. 4, meet the above conditions to save cement and reduce the cost of concrete. The strength of concrete is divided into twelve grades, such as C7.5, C10, C15, C20, C25, C30, C35, C40, C45, C50, C55, C60 and so on.

Here, a new concrete hydrophobic treatment method is developed using SiO2 sol and silane emulsion. The effectiveness of the modification for concrete protection is evaluated through testing water absorption and chloride diffusion. Two types of concrete with different strength grades (C40, C50) are used as the research object. The results show that the water capillary absorption coefficient and ...
