The Experimental Research of a Heavyweight High-strength Concrete

摘要

The definition of heavyweight high-strength concrete (HHC for short) is firstly introduced. According to the characteristic targets of a HHC, suitable experimental material and project are chosen. Via analyzing and commenting on various properties of different minerals such as silica powder and fly ash, a feasibility study for mixed them into concrete to manufacture HHC is conducted, and its mechanics properties and Alkali-resistant property are tested. On the basis of them, HHC whose strength is C60 and apparent density is 2800 kg/m~3 is successfully manufactured. The optimum proportion is given out.
