摘要
大量试验表明:粉煤灰水泥混凝土具有和易性好、拌和省时、节约水泥并降低其水化热温升;减少混凝土尚未终凝时产生的塑变裂纹;且具有高强度、高抗渗透性、高耐久性,是一种应用于公路建筑工程的好材料。
A large number of tests have been proofed that:cement concrete of coal ash powder has many advantages such as:easy to mix,save time to mix,save cement and reduce temperature for cement to hydrolysis,also reduce modeling crack while cement hasn't been curdled.In addition,it has higher strength,higher anti-permeate function and longer endurance.It is one of the benefit materials in highway construction.
