本文通过砂浆与混凝土对比试验,确认了砂浆坍落扩展度与混凝土坍落扩展度具有很好的线性相关性。与混凝土试验相比,砂浆坍落扩展度试验具有试验简单、省时、省料,可靠,能有效地检测和评价泵送混凝土胶凝材料和外加剂的相容性。 In this paper, mortar and concrete comparative tests confirmed that the mortar slump expansion and concrete slump expansion has a good linear correlation. Compared with the concrete test, the mortar slump expansion test has the advantages of simple test, time saving, material saving and reliability, and can effectively detect and evaluate the compatibility of the pump concrete cementitious material and the admixture.
