查询词典 concrete

Directed against the existing problems in traditional mixing process, secondary mixing techniques, such as pre-mix cement mortar, pre-mix cement paste, sand enveloped with cement paste, coarse aggregate enveloped with cement paste and aggregate enveloped with cement paste are discussed, and the effect of different mixing technological processes on concrete mixing quality is studied. The homogeneousness, compression strength of concrete and the power consumption are tested during the test, and compared with the traditional mixing method.
