ＵＥＡ补偿收缩混凝土性能试验研究江西省建材科研设计院刘慕丹，刘松柏，方春霖，唐琳一、前言普通砼是一种用途广泛用量很大的最常用建筑材料，它有许多的优点，但也存在一些缺点。如抗拉强度低，极限延伸率小。当砼产生干缩或冷缩时，如果砼受到约束，不能自由变形，则... UEA Compensation for Shrinkage Concrete Performance Test Study Jiangxi Provincial Building Materials Research and Design Institute Liu Mudan, Liu Songbai, Fang Chunlin, Tang Linyi, foreword Ordinary earthworm is one of the most commonly used building materials with a wide range of uses. It has many advantages, but it also exists. Some disadvantages. If the tensile strength is low, the ultimate elongation is small. When the crucible produces shrinkage or shrinkage, if the crucible is restrained and cannot deform freely, then...
