油菜秸秆和粉煤灰对砂浆性能影响因素分析

Analiysis on the Factors Affecting of the Straw and Ash on the Performance of Mortar

研究了不同油菜秸秆掺量(0、4%、6%、8%),不同粉煤灰掺量(0、10%、15%、20%)对砂浆流动性能、7d和28d抗压强度、热工性能的影响,并分析了秸秆和粉煤灰对于砂浆性能的影响程度。结果表明,两种材料对于砂浆的流动性、抗压强度、热工性能都有较大影响,在一定的掺量组合下可以实现建筑材料和废弃物的结合利用。

When the dosage of rape straw and fly ash is respectively 0, 4%, 6%, 8% and 0, 10%, 15% and 20%, theinfluence on the fluidity of mortar test block, 7d and 28d compressive strength, thermal performance are analyzed. Theresults show that the two kinds of materials have great influence on the fluidity, compressive strength and thermalperformance of mortar. The combination of building materials and waste can be realized under a certain amount of mixing.
