摘要: A light-weight concrete having a density of 800 - 1,800 kg/m3 consists essentially of a coarse aggregate, a fine aggregate, cement, and water, the coarse aggregate being at least 50 percent of all solids by volume, the fine aggregates being constituted by fine said of less than 1 mm grain size, crushed mineral material such as crushed brick of less than 5 mm grain size and pulverized mineral material, such as powdered brick of a grain size of less than 2 mm.
