Answer to Question #234150 in Mechanical Engineering for Janu

Question

16. Can grout replace concrete in normal structure?

Answer 1

The mixture of cement and water alone cannot replace concrete because;

$(i)$ Shrinkage of grout is several times that of concrete with the same mass.

$(ii)$ The effect of creep of grout is far more than that of concrete.

$(iii)$ Heat of hydration of cement with water is more than normal concrete and this leads to the problem of severe cracking.
