Jun 17, 2020· B. IS 456-2000 has designated concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35, and M40. In this designation, the letter M refers to the mix and the number to the specified 28-day cube strength of mix in N/mm2. C. Design Mixes In these mixes, the performance of the concrete is specified by the designer but the mix proportions are determined by the producer of concrete ...
Jun 13, 2020· Step-4 : Calculation of cement + fly ash content . w/c ratio = 0.40. Water used = 148 litre. Cement + fly ash content, w/c = 0.40 . C = 148/0.40 = 370 kg/m 3. As per IS: 456_2000. Table_5. Minimum cement content for severe exposure condition. 370 kg/m 3 > 320 kg/m 3 hence O.K. Since fly ash is not as active as that of cement. It is usual to ...
Jan 26, 2017· Calculation Of Materials For Different Mix Ratio: Quantity estimation of materials is essentially required in any construction works and quantity of materials depend on the mix proportions of the concrete. In our previous article, we have already discussed how to calculate bricks in a wall. Today we will discuss how to calculate quantities of materials [.]
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

Understanding Concrete Grades . Based on strength, concrete is classified into different grades like M5, M7.5, M10, M15, M20 etc. In concrete grades, the letter "M" stands for "Mix" and the following number stands for characteristic compressive strength of concrete in 28 days in the Direct Compression test.
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:
Sep 17, 2017· Concrete is described as per IS 456-2000 has designated the concrete mixes into two 1. Nominal Mix 2. Design Mix. In Nominal mix ratio of different material are already defined while in the design mix ratio is defined after the testing with different trial mixes. Grade of concrete are such as as M10, M15, M20, M25, M30, M35 and M40 e.t.c.
Calculating Quantities of Materials for per cubic meter or cubic feet or cubic yards concrete. Consider concrete with mix proportion of 1:1.5:3 where, 1 is part of cement, 1.5 is part of fine aggregates and 3 is part of coarse aggregates of maximum size of 20mm.
