负温混凝土成熟度的理论计算和试验应用等问题,本刊在1987年第一期已做了介绍。本文根据几年来负温混凝土的试验和施工应用,着重介绍适应泵送大坍落度负温混凝土成熟度的试验、应用和应用条件等问题,提出负温混凝土成熟度的常数值、计算出负温混凝土抗压强度的线性回归方程和R—M
The theoretical calculation of the maturity of the negative temperature concrete and the application of the test have been introduced in the first issue of 1987. Based on the tests and construction applications of negative temperature concrete for several years, this article focuses on the problems of testing, application, and application conditions for adapting to pumping large slumps of negative temperature concrete, and proposes constant values of the maturity of negative temperature concrete, and calculates negative values. The Linear Regression Equation and R-M of Compressive Strength of Warm Concrete
