【摘要】 利用氨基磺酸盐系、萘系减水剂及缓凝、引气和浆体稳定组分复配出适用于大体积高流态混凝土的高效泵送剂,通过胶砂强度实验得出矿渣和粉煤灰的最佳掺量比例;采用最佳浆骨比法设计混凝土配合比,经过计算検耘錀调整的方法确定了C30大体积高流态混凝土的高性能化设计方案;并通过计算检验混凝土温度以避免大体积混凝土施工过程中温度裂缝出现。更多还原

【Abstract】 Compounded a kind of pumping superplasticizer with aminosulfonic acid-based,naphthalene superplasticizer,setting retard aid,air entrening aid for mas and high fluidity concrete,studied optimum ratio of slag and fly ash by cement motar stength;designed mix proportion based on the optimum paste aggregate ratio.build optimum mix proportiono of C30 mass high fluidity concrete by trial-calculating-trial method;calculated tempreture of concrete for aoviding cracks while building mass constracture.更多还原
