Concrete Engineering

1. Commodity concrete, also known as pre-mixing concrete, referred to as the (commercial concrete), commonly known as ash or material: by the cement, aggregate, water and admixture, mineral admixture composition in accordance with a certain proportion, Station after the measurement, mixing and sale after the use of transport vehicles, within the specified time to reach the use of concrete mixing site. Concrete to the site after the general by the dump, pump and ground pump way to the ground, and then by the height of the workers in accordance with the height of the concrete paved.

Steel fiber reinforced concrete is a kind of new multiphase composite material which is made up of short steel fiber with random distribution in ordinary concrete. The distribution of cracks in the short steel fibers can effectively prevent the expansion of micro cracks inside the concrete and the formation of macro-cracks, significantly improved the tensile, bending, impact resistance and fatigue resistance of concrete, has good ductility. Steel fiber reinforced concrete is different from the traditional reinforced concrete or plain concrete floor, steel fiber to replace the original reinforcement reinforcement than the traditional reinforcement performance, greatly shorten the construction period, reduce construction costs and reduce the amount of steel more energy saving and environmental protection.
