摘要
从材料角度出发,在一般喷射混凝土试验的基础上,通过一系列正交试验分析出陶粒类型、掺量及玻化微珠掺量对新型混凝土材料的抗压强度、抗弯强度及导热系数的影响。论证新型混凝土材料对深井热害问题的适用性与可行性。
From the viewpoint of materials exactly,based on the experiment of the general sprayed concrete,exerts the way of orthogonal experiment,and the law effect of the type of the haydite,mixing amount of haydite,mixing amount of glazed hollow bead and new concrete material on compressive strength,flexural strength and thermal conductivity has been analyzed. Therefore,the applicability and feasibility of the new concrete material for the question of heat-harm in deep well were demonstrated.
