坍落度试验是评价新拌混凝土工作性的传统方法。泵送混凝土工作性主要指可泵性,单纯以坍落度为指标已不足以评价其可泵性的好坏。本文对评价泵送混凝土可泵性的若干方法进行了评述,并初步确定了新拌混凝土的可泵性区间。
Slump test is to evaluate the workability of fresh concrete traditional method. Pumped concrete work mainly refers to the pumpability, simply to slump as an indicator has not enough to evaluate the pumpability is good or bad. In this paper, several methods for assessing the pumpability of pumped concrete are reviewed, and the pumpability interval of fresh concrete is preliminarily determined.
