摘要
本文主要介绍《轻集料混凝土技术规程JGJ51-90》在轻集料技术性能,轻集料混凝土强度等级等方面新修订的内容;同时,重点阐明了将轻集料混凝土碳化合格性指标首次列入规程的依据;并且在轻集料混凝土配合比设计、弹性模量、收缩与徐变,及热物理参数等指标与国外同类规程进行对比。
This paper introduces the technical characteristics of lightweight aggregate and the strength gradation of lightweight concrete in the newly revised 《Technical Specification for Lightweight Aggregate Concrete》 (JGJ 51-90), with the emphasis on the basis of the carbonization qualification index of lightweight aggregate concrete, which is first listed in the specification. Besides, mix design, modulus of elasticity, shrinkage and creep, and termophysical coefficients of lightweight aggregate concrete are compared with the provisions in relevant foreign specifications.
