我国黑龙江、吉林、辽宁、内蒙、山西等地蕴藏着极其丰富的火山爆发形成的天然轻骨料——浮石,由于资源丰富,开采方便,节约能源,性能优越.因此,在建筑工程中日益得到广泛推广和应用.近年来,用浮石配制的轻骨料混凝土在我省初步统计,在十多万平方米建筑中应用,效果很好.我们在试验中配制了300~#浮石混凝 China’s Heilongjiang, Jilin, Liaoning, Inner Mongolia, Shanxi and other places have abundant pumice, a natural lightweight aggregate formed by volcanic eruptions. It is rich in resources, easy to extract, energy-saving, and superior in performance. Therefore, it is increasingly gaining in construction projects. Widely promoted and applied. In recent years, lightweight aggregate concrete formulated with pumice stones has been preliminary statistics in our province. It has been applied in over 100,000 square meters of buildings. The effect is very good. We have prepared 300~# pumice stone coagulation in the experiment.
