摘　　要：研究了以铝酸盐水泥为胶凝剂,以具有较大比热容的焦宝石和铝矾土等作为集料,添加高导热性的碳化硅和钢纤维,并选用性能优异的复合高效减水剂,制备可用于聚光式太阳能热发电的新型混凝土储热材料。A new type thermal storage concrete applied for solar thermal power was fabricated by using aluminates cement to be bonding material, using high heat capacity aggregate such as flint clay and bauxite, and adding a small amount of SiC and steel fibers with high heat conductivity. The high efficient water reducing agent was also used. The performance of thermal storage concrete can meet the demands of application in solar thermal power.
