Building Material: Concrete

Amajority of commercial and industrial structures do construct from concrete. It’s popular because of its durability and strength. It’s a composite material made chiefly from aggregate and cement.

Portland is the most commonly employed concrete today. It comprises minerals like gravel and sand portland cement, as well as water to mix, soften and hydrate later.

Concrete, however, has a weak tensile strength. The use of steel rods or rebars usually reinforces it. Thus we get the strengthened concrete constructions.

Air bubbles are the main reason that weakens the concrete. Concrete pouring during construction must treat with consideration. Vibrators are employed to eliminate bubbles that form in the process of pouring.
