what is the concrete ratio in Class D2 concrete
40 20 concrete design mix is the water to cementitious materials ratio. This is what determines the class of the design mix.
M40 Concrete ratio 1:1.65:2.92 (cement:FA:CA)W/C ratio = 0.4As per Indian Standards.
1:2:3
class in which objects can be created is called as concrete class.

40 20 concrete design mix is the water to cementitious materials ratio. This is what determines the class of the design mix.
M40 Concrete ratio 1:1.65:2.92 (cement:FA:CA)W/C ratio = 0.4As per Indian Standards.
Multiply the ratio by 100 and convert to decimal form (or convert and then multiply).
1:2:3

not class B
Why does concrete mix with low water cement ratio resulted in hardened concrete having higher strength than those with high water cement ratio?
weight of 1 cubic mitre of concrete
Convert the ratio to fraction first, then convert the fraction to decimal. Example: ratio = 3 : 4 3 : 4 = 3/4 = 0.75
the strength of concrete is effected by water /cement ratio as the water/cement ratio increases the strength of the concrete decreases
Ratios are good for comparing two quantities. Like in a classroom, the ratio of girls to boys, for example. Say the class has 40 students, and 22 of them are girls, so this is 22/40 = 55% of the class. But the ratio is comparing the girls to the boys, not the entire class. So if there are 55% girls, then 100% - 55% = 45% boys. Now the ratio can be made of 55 : 45 girl to boy ratio. This can be simplified to a 11:9 ratio.
