The manufacture and use of concrete develop an array of environmental, financial and social impacts.

The phrases asphalt (or asphaltic) concrete, bituminous asphalt concrete, and bituminous combination are usually applied only in engineering and building files, which determine concrete as any composite material composed of mineral aggregate adhered that has a binder.

A tremie is often a vertical, or near-vertical, pipe that has a hopper at the very best accustomed to pour concrete underwater in a means that avoids washout of cement with the blend as a result of turbulent drinking water connection with the concrete though it's flowing.

The binder must fill the gaps involving the aggregate and paste the surfaces on the mixture alongside one another, and is typically the most expensive element.

The sturdiness of prestressed concrete is principally based on the level of corrosion protection provided to any superior-toughness steel elements throughout the prestressing tendons. Also important could be the defense afforded to the tip-anchorage assemblies of unbonded tendons or cable-continue to be devices, since the anchorages of each of they are needed to retain the prestressing forces.

Bonded submit-tensioning characteristically takes advantage of tendons Each and every comprising bundles of features (e.g., strands or wires) placed within one tendon duct, apart from bars which happen to be mainly used unbundled.
