浮石——是火山爆发后,岩浆喷落到地面冷却而形成的轻质石料。它呈蜂窝状结构,气孔多而不贯通,颜色有黑、深灰、铁锈黄、赭红等。它体轻、强度高,并有良好的保温性能和活性。它既是一种理想的混凝土轻骨料,又是极有前途的新型墙材料,还是良好的水泥混合材。内蒙古乌兰察布盟、锡林郭勒盟等地,浮石资源极为丰富。后旗乌兰哈达火山群浮石储最在一亿立方米以上。这些矿开采十分方便。开采后有的不须加工,有的只须破碎筛分即可
Pumice stone - is a light stone formed after the volcano erupts and the magma drops to the ground to cool. It has a honeycomb structure, many pores but not through, color black, dark gray, rust yellow, blush and so on. It is light, high strength, and has good insulation properties and activity. It is not only an ideal concrete lightweight aggregate, but also a promising new wall material, or a good cement admixture. In Wulanchabu League and Xilin Gol League in Inner Mongolia, pumice resources are extremely abundant. After the flag of Ulan-Hada volcanic group, the pumice is more than 100 million cubic meters. The mining is very convenient. After mining, some do not need to be processed, some only need to crush and sieve
