The ratio of water to cement in your batch of concrete remains one of the most influential factors as to how long a concrete slab needs to cure and dry. External sources of concrete moisture can also be substantial and include such things as rainwater, poor plumbing, poor drainage below or at the sides of the slab, and even the humidity in the air.
Mar 09, 2020 Effect on grinding efficiency and hot air drying . dryer; rotary kiln dryer; Water is the main factor affecting the grinding efficiency, the greater the water grinding efficiency is lower, the new dry cement mill production, in theory, the lower the requirement of the material water, the better, in the case of insufficient drying capacity, raw material water at 1.5% when …

A highly porous material, cement tends to absorb water from precipitation and even ambient humidity. Researchers discuss just how the material's porous network absorbs water and propose how drying permanently rearranges the material and leads to potential structural damage.
The effect of grinding hydrated tricalcium silicate (C3S) pastes on the bound water content (BWC) measured by thermogravimetric analysis was investigated. The samples were subjected to different curing regimes at 20°C and 40°C at a constant water to cement ratio of 0·5. Hydration reactions were stopped using a freeze drier. To study the effect of grinding, samples were either roughly ...
