Abstract
In the construction engineering, if builders want to control the concrete engineering, they must first to control wel the quality of raw materials. Concrete structure accounted for a large proportion of building engineering, so the safety, reliab-ility and durability of a construction depends largely on the concrete structure. This paper simply introduced the proportion, raw material and technology of concrete.关键词
