How batching of concrete is done - Construction_Cost

Volume Batching of Concrete: Volume batching of concrete is accomplished with the use of measurement boxes, locally named “farmas or gauge boxes”. Concrete components like aggregates ( Kapachi +Sand) and cement is calculated with farmas or gauge boxes and

Lab 1 – Concrete Proportioning, Mixing, and Testing

Concrete is cured in a wet environment in order to avoid loss of moisture through evaporation. The chemical reaction of water and Portland cement binds the aggregate particles in concrete. This reaction, known as the cycle of hydration, takes place slowly
