粉煤灰是砂浆的良好掺合料。粉煤灰不会自身硬化,当与石灰(生石灰、消石灰)混合后,才具有水硬性胶凝物质的性质。一、石灰膏掺量对砂浆强度的影响石灰膏是粉煤灰中活性氧化物的激发剂。其用量多少,以粉煤灰活性大小,并通过试验来确定(表1)。由表1可知,就洛阳电厂湿排灰而言,石灰膏掺量占总掺合材料的25％时,其强度较高。 Fly ash is a good admixture of mortar. Fly ash does not harden on its own, and it only has the properties of hydraulic binder when mixed with lime (calcaree, hydrated lime). First, the effect of lime paste dosage on mortar strength Lime paste is the active oxide activator in fly ash. The amount of its use, with the size of fly ash activity, and determined by the test (Table 1). From Table 1, it can be seen that in terms of wet ash discharged from Luoyang Power Plant, the intensity of lime paste is 25% higher than that of the total blended material.
