Answer / sara. M20=1:1.5:3 Dry volume of concrete in 1cum=1.54 Cement Quantity=1.54/(1+1.5+3) =0.28cum =0.28/0.035=8 bags =0.28*1440=403.2kg same way we can calculate M25 cncrete

The commonly used grades of concrete are as follows, M10 M15 M20 M25 M30 M35 M40

Nominal mixes for grades of concrete such as M15, M20, M25 are generally used for small scale construction. Large structures have high strength requirements, thus they go for higher grades of concrete such as M30 and above. The mix proportions of these concretes are based on mix design.

Sep 19, 2018· M20 GRADE Where M stands for Mix ration & 20 stands for compressive strength of a 150mm cube after 28 days of curing, expressed in N/mm2 Mix ratio is 1:1.5:3 (1 Cement, 1.5 Sand and 3 Aggregate) It is used as RCC (Reinforced Cement Concrete) It is...

What is the ratio of Grades M10,M15,M20,M25,M30,M35,M40... Answer / brajesh kaurav. ratio of M10-1:3:6 M15-1:2:4 M20-1:1.5:3 ... No where code IS is specified mix ratios for grade of concrete. But IS 456-2000 table no 9 is given guideline for nominal mix of grade M5 to M20 by weigh batches.

According to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days. Why do we test at 7, 14 & 28 days? Concrete is a macro content with Sand, Cement, & Coarse aggregate as its micro-ingredient (Mix Ratio) and gains its strength over time at the hardened state.

Target Strength for Mix design of M20 as per clause number 4.2 Page no 02 of IS 10262: 2019 As per IS 10262 : 2019 Table 1 and Table 2 of page no 3 F'ck = fck + 1.65 X Standard deviation OR F'ck = fck + factor based on grade of concrete, whichever is higher For Mix design of M20 grade concrete Factor based on grade of concrete = 5.50

III. TARGET STRENGTH . Apart from mix design, the strength of the concrete depends on other factors like mixing method, climate etc. Hence Target strength (F ck) should be more than designed characteristic strength (f ck).Target strength for m20 grade concrete can be found from the formula given in the codebook.
