أكمل القراءة· Dry process method means manufacturing raw materials into raw materials powder, whose water content is generally less than 1%. So, the dry process can `reduces heat loss needed by heating and autoclaving water. But the dry process has its own flaw that is the bad fluidity of materials grain in a kiln. It will cause an uneven mix.
أكمل القراءة· Whereas dry concrete has resistivity in the range of 1012 ohm-mm. Hence oven dry concrete acts as an insulator. The variation in the measured electrical resistivity in wet and dry concrete can be interpreted to find that the electrical conductivity of concrete is a significant effect of the evaporable water present in it.
