净浆裹石工艺在配制高强混凝土中的应用研究

Research of Stone Enveloped with Cement in producing high strength concrete

采用普通原材料和净浆裹石工艺,通过正交设计试验研究,配制了强度为80 M Pa的高强混凝土,给出了优选配比。试验结果表明:净浆裹石搅拌工艺可以改善界面过渡区结构,提高混凝土的强度和耐久性。

The high strength concrete was investigated by using ordinary materials with mixing method of Stone Enveloped with Cement （SEC） in this orthogonal experiment. And the optimal mix proportions were recommended. The result of the experiment shows that Stone Enveloped with Cement can meliorate distinctly the structure of the transition zone of interface, thus the strength and endurance of concrete are improved.
