摘要

摘要本研究探讨了再生细骨料和废粉在砂浆中的应用,并对其中的火山灰反应及其对砂浆强度性能的影响进行了实验研究。试验结果表明:再生砖细粒砂浆的抗压强度在7 d时低于对照砂浆,在72 ~ 92%范围内,在90 d时分别达到82 ~ 98%。由于水泥的减少,废粉砂浆的强度不能达到对照砂浆的强度水平,并且砂浆的强度随着水泥替代比的增加而降低。在后期(56天和90天),废粉砂浆中水泥的强度效率随废粉替代率的增加而增加。这可以解释为,废粉由主要的酸性氧化物组成,可以触发火山灰反应,为砂浆提供额外的强度增益。

Potential pozzolanic reactivity of recycled aggregates and waste powders as cement mortar component
ABSTRACT In this study, the use of recycled fine aggregates and waste powders in mortar was discussed, in which the pozzolanic reaction and the effect on strength properties of the resulting mortar were experimentally investigated. Test results showed that the compressive strengths of mortars with fine recycled brick and tile particles were lower than those of the control mortar at age of 7 days in the range of 72–92%, but reached 82–98% at age of 90 days, respectively. Because of the cement reduction, the mortars with waste powder cannot reach the strength level of the control mortar, and the strength of the mortars decreased with the increase in the cement replacement ratio. The strength efficiency of cement in mortar with the waste powders mortars increases with the increase of waste powder replacement ratio at later ages (56 and 90 days). This may be interpreted by the waste powders, being composed of major acidic oxides, could trigger the pozzolanic reaction to provide additional strength gains for mortar.
