M20 (1 cement :1.5 sand :3 stone/brick aggregate). To determine the proportions you have to perform mix design, for this you have to find out the sp.gr. of cement, CA, FA, and water cement ratio ...
One bag of cement and other ingredients can produce = 400/2400 = 0.167 Cum of concrete (1:2:4) 01 bag cement yield = 0.167 cum concrete with a proportion of 1:2:4. 01 cum of concrete will require. Cement required = 1/0.167 = 5.98 Bags ~ 6 Bags. Sand required = 115/0.167 = 688 Kgs or 14.98 cft. Aggregate required = 209/0.167 = 1251 kgs or 29.96 cft
M25:: 1:1:2 Total parts is 4 Cement part is 1/4 Dry Volume of M25 is approx 1.57 times of total volume Density of Cement is 1440 Cement Required for 1 cum =1/4X1.57X1440=565.2 approx cu. mtr. for Bags (india cement bags) is of 50kg so 565.2 kg /50kg = 11.304 bags per cu. mtr. So as with sand dry volume if always 1.57 for required volume
Mix proportioning for a concrete of M25 grade is given in A·I to A-ll. A·I STIPULATIONS FOR PROPORTIONING. a) Grade designation : M25 b) Type of cement : OPC 53 Grade conforming IS 12269 c) Maximum nominal size of aggregate : 20mm d) Minimum cement content : 300 kg/m 3 (IS 456:2000) e) Maximum water-cement ratio : 0.50 (Table 5 of IS 456:2000)
M-25 CONCRETE MIX DESIGN . As per IS 10262-2009 & MORT&H . A-1. Stipulations for Proportioning: 1. Grade Designation : M25: 2. Type of Cement: OPC 53 grade confirming to IS-12269-1987
Coarse Aggregate = (Coarse Aggregate Part / Concrete Parts ) * Concrete Volume = (3/5.5) * 2 = 1.09 m 3 . Water Cement Ratio. According to IS 10262 (2009), Assuming Water-Cement Ratio for the Concrete as 0.45. Required Amount of Water = W/C Ratio X Cement Volume
In this civil engineering article, the calculation is done to determine the quantity of water for M25 grade of concrete. Here, the volume of concrete is taken as 1m 3.. Initially, it is required to find out the quantity of cement for 1m 3 concrete with m25 grade:-. For 1m 3 concrete, the quantity of cement required = 9.51 bags. As we know, 1 bag of cement is equivalent to 50 kg
Quantities of materials for concrete such as cement, sand and aggregates for production of required quantity of concrete of given mix proportions such as 1:2:4 (M15), 1:1.5: 3 (M20), 1:1:2 (M25) can be calculated by absolute volume method. This method is based on the principle that the volume of fully compacted concrete is equal to [.]
Concrete mix design is a method of calculating right proportions of cement, sand, and aggregates for concrete to achieve target strength in structures. The Concrete mix design Concrete Mix = Cement:Sand:Aggregates. For a mix design of concrete, we have to follow various steps, calculations, and laboratory testing to find the right mix proportions.
Weight of Cement required for 1 cubic meter of M20 Grade concrete. Weight of cement required can be calculated from multiplying the volume of cement with the bulk density of cement. The bulk density of frequently used cement varieties (both PPC and OPC) is 1440 kg/cu.m.
You can reduce the water-cement ratio for M25 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 get up to 50mm slump is given in Table 2 of IS10262.

Apr 23, 2018· Enter the thickness, width and length to find the number of cubic yards or bags of concrete needed for your project. Give these calculations to your ready-mix supplier or use them to estimate how many 40, 60 or 80 lb. bags of concrete to buy.
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 : Cement, Sand and Aggregate calculator. CONCRETE MIX DESIGN
Volume of Cement = 1/4 x 1.55 Volume of Sand = 1/4 x 1.55; Volume of Coarse Aggregate = 2/4 x 1.55; From the IS Code standard, Assuming the water-cement ratio for M20 is 0.5; The reason for that 1.55 has been already discussed in the concrete ingredients calculation topic. So the required Cement Volume – 0.3875 m3 or 11.16 Bags
