The process will involve polymerization, the interlinking of your silicates and aluminate factors and also their bonding to sand and gravel particles to type a stable mass.[47] One particular illustrative conversion may be the hydration of tricalcium silicate:
In heat climates, that is a lesser issue. Concrete houses could be a sensible choice in warm temperatures simply because they have a tendency to help keep the house rather cool with small to no insulation.
