摘   要：针对面板混凝土需要简化温控、提高抗裂和耐久性的要求，提出高掺粉煤灰与掺入GTA高性能减水剂共同作用的混凝土制备方法，并进行了混凝土强度、极限拉伸值、抗渗性和抗冻性的试验研究。结果表明，在高掺粉煤灰时，GTA高性能减水剂的应用提高了面板混凝土的抗裂性，其中极限拉伸值提高了14%。同时，混凝土抗冻性可大于F100，抗渗性提高到W18，表明高掺粉煤灰面板混凝土的耐久性能够满足设计需要。

Abstract：Aimed to the requirements on the simplified process of temperature control and to improvement on the crack resistance and durability for the panel concrete, a kind of preparation method for concrete was investigated, which was made with the cooperation of high-dosage fly-ash (50% or 60%) and high performance water reducer GTA. Meanwhile, the compressive strength, ultimate tension rate, impermeability and frost resistance of concrete were tested. And the results show that the GTA, together with high-dosage of fly-ash will improve the crack resistance of panel concrete, among which the ultimate tension rate will increase14%, the frost resistance of concrete can reach more than F100 and the impermeability will be up to W18. That is to say the durability of panel concrete with high-dosage fly-ash can satisfy the design requirement.
