研究了不同煅烧温度对废砂浆块易磨性、流动度、质量损失的影响,以及废砂浆粉的活性激发效果.实验表明,废砂浆粉筛余率和胶砂流动度随着煅烧温度的升高而显著降低.经600℃热处理,掺30%废砂浆粉混合水泥的28 d强度增长了3.01 MPa,结合分离废弃混凝土中砂浆组分的最佳温度在500℃~600℃,确定了600℃是分离和激发废砂浆活性的最佳温度.

The effect of different calcination temperatures on the abrasive, fluidity, quality loss and the activity of waste mortar are studied. Experimental results show that waste mortar powder sieve residue rate and mortar fluidity as the calcination temperature increases significantly reduced. The 600 degrees Celsius heat treatment, mixed with 30%of waste mortar powder mixed cement 28 day strength increase of 3.01MPa, combined with separation of waste concrete mortar was the optimum temperature in the conclusion of 500 to 600 degrees to determine the 600 degrees is the separation and stimulate the optimal temperature for activity of waste mortar.
