【摘要】 以云南大朝山水电站施工所采用的混凝土配合比作基准混凝土，探讨了磷渣作为单独的掺和料掺入到混凝土中，给混凝土的各性能造成的影响及影响机理。认为，磷法作为一种新的混凝土掺和料，尤其适用于水工大体积混凝土的内部。更多还原

【Abstract】 Taking the concrete mix used in the Dachaoshan hydroelectric power project in Yunnan as a norm mix, this paper has a discussion on the effect and its mechanism on the concrete performance when phosphorous slag was added to concrete as a sole admixture. The authors consider that as a new concrete admixture the phosphorous slag is particularly suitable for use in internal part of hydraulic structure mass concrete.更多还原
