通过净浆、砂浆与混凝土流动性的相关性试验,确认了砂浆坍落扩展度与混凝土坍落扩展度具有很好的相关性。与采用净浆法检测粉煤灰相比,可靠性更高,与混凝土试验相比,砂浆坍落扩展度试验更省时、省力,能有效检测和评价粉煤灰对混凝土的流动性影响。
Through the test of the correlation between the fluidity of mortar and concrete, it is confirmed that there is a good correlation between the slump of mortar and the slump of concrete. Compared with the test of fly ash with the mortar, the reliability is higher. Compared with the concrete test, the mortar slump expansion test is more time-saving and labor-saving, which can effectively detect and evaluate the influence of fly ash on the fluidity of concrete.
