当前我国人造轻集料(陶粒)年产量约360万立方米,而且增长速度较快,其中绝大多数被用于制作轻集料混凝土小型空心砌块。加上利用天然轻集料、煤渣等工业废渣轻集料的混凝土砌块,目前全国轻集料混凝土小型空心砌块的总产量约在1500万立米左右。但是,从中国建筑砌块协会最近在呼和浩特市召开的“轻集料混凝土小型空心砌块生产应用技术交流研讨会”传出的信息,轻集料混凝土空心砌块的质量形势不容乐观。在最近进行的新型墙体材料产品质量国家监督抽查中,对两个省抽查轻集料小型空心砌块生产企业13家的13个产品,检测合格率仅为61.54%,而同时抽检的混凝土小型空心砌块,产品合格率是100%。
At present, China’s artificial light aggregate (ceramsite) annual output of about 3.6 million cubic meters, but also faster growth, the vast majority of which are used to make light aggregate concrete small hollow block. Coupled with the use of natural light aggregate, cinder and other industrial waste light aggregate concrete block, the current national light aggregate concrete small hollow block of the total output of about 15 million cubic meters. However, from the recent report by China Building Block Association in “Symposium on the Exchange and Application of Lightweight Aggregate Concrete Small Hollow Block Production and Application Technology” held in Hohhot, the quality situation of light aggregate concrete hollow block is not optimistic. In the recent national quality supervision and spot check of new wall materials, 13 products of 13 light aggregate small hollow block manufacturers were inspected in two provinces with a passing rate of only 61.54%. At the same time, the small concrete samples Hollow block, the product pass rate is 100%.
