Mix proportion of c25 concrete

Water: 195kg cement: 443kg sand: 56 1kg stone:11kg.

The mixing ratio is 0.44:1:1.312: 2.666.

Second, the concept of concrete construction mixture ratio:

The concrete construction mixture ratio refers to the mixture ratio adopted in the concrete construction process.

Adjustment steps: if the laboratory mix ratio is cement: sand: stone = 1: x: y, the water content of sand is m, and the water content of stone is n, then the construction mix ratio is adjusted to:1:x/(1-m): y/(1-n).

Concrete mix design is a very important work in concrete engineering, which directly affects the smooth construction, quality and cost of concrete engineering.
