Feb 07, 2017 With constant research and development in the field of cement technology and its manufacturing process ,a M20 mix of “1:1.5:3″(by volume) would be too rich,over engineered and uneconomical (~7.5 bags of cement per cum) and will ultimately result into a M30 concrete and above, the reason being latest generation of 53 grade OPC cement is

Excess reducing of cement content or increase of sand content will adversely affect the strength of concrete. Hence it is advisable not to increase the fine aggregate (river sand and M sand) content more than 30% above the prescribed ratio in any case.

Apr 23, 2018 Estimating concrete steps. Steps seem tricky to calculate but are not. If there are three steps leading up to a porch: Use the slab calculator to figure the concrete needed for the porch surface. Use the footing calculator to calculate the sides of the porch and the steps; Here is an example:

Concrete Ingredients Calculation. For Cement, Sand and Coarse Aggregate. This is a Volumetric Calculation. Assuming we need 2 m 3 of concrete for M20 Concrete Mix, (Mix Ratio, M20 = 1 : 1.5 : 3) Total Part of the Concrete = 1+1.5+3 = 5.5 Parts. Therefore, Cement Quantity = (Cement Part / Concrete Parts ) * Concrete Volume

Sep 19, 2020 Water/cement ratio = 0.5 Estimated water content = 191.6 kg /m3 As per IS 456 Table No 5 Minimum cement Content = 300 kg/m3 ( mild exposure condition ) 383.2 kg/m3 > 300 kg/m3, (OK) Now check for durability requiremnt from IS 456 In the present scenario against mild exposure and for the case of reinforced concrete the minimum cement content is

You can reduce the water-cement ratio for M30 grade concrete based on your requirements, but remember that Water-cement ratio directly affects the strength of the concrete. V. SELECTION OF WATER CONTENT. Maximum water content for 20mm aggregate to

Design of M30 Grade Concrete mix According to IS 10262:2009 Assume : Type of Cement: 53 Grade Specific Gravity of Cement : 3.01 Coarse Aggregate : 20 mm Crushed Granite Specific Gravity of Coarse Aggregate : 2.78 Specific Gravity of Fine Aggregate...

In this example for mild exposure and for the reinforced concrete the minimum cement content is 300 kg/m 3 which are less than 383.2 kg/m 3. Hence cement content adopted = 383.2 kg/m 3. IS: 456: 2000, clause 8.2.4.2. Maximum cement content for mix = 450 kg/m 3. Read More : Building Estimation Excel Sheet Free Download

Several attempts have been made to devise a method of determining the cement content of fresh concrete. A few years ago a new concept of such a test was originated by R. A. Willis. To separate the cement from the aggregate, Willis employed a heavy liquid in which the aggregate would float but the cement being heavier would settle to the bottom.
