摘　　要：结合工程实例,研究了复合双掺高性能海工混凝土中矿物外掺料掺量、水胶比和胶凝材料用量对混凝土工作性能和力学性能的影响规律。结果表明:增大上述参数值可有效改善混凝土的工作性能和力学性能,但应结合经济等其他因素综合考虑,确定最佳取值。The influence rules of mineral admixture, water-binder ratio and cementing material amount on the concrete working performance and mechanical property of high concrete mixed with two types of mineral admixtures were studied combined The results show that increasing the values of those factors could effectively i performance and mechanical properties of concrete, but the best values should considering economy and other factors.
