How To Know Sand Content In 1 Metre Cube Of Concrete

to mix 1 cubic meter of cement at a ratio of 3:1 how many 20kg of sand and 25kg bags of cement will be needed? we have now cut down to 1/2 a cubic metre apparently.The consensus for 1/2 a cube seems to be, 1 tonne sand, 14 bags cement.This should give 3:1 by volume! ( use a bucket for easy and accurate measuring.Do not mix it by weight).

We are committed to building crushing, industrial grinding, ore processing and green building materials, and provides intelligent solutions and mature supporting products.
