Lightweight core-shell aggregate and concrete
The invention provides a high-strength and light-weight core-shell type aggregate prepared from waste materials. The aggregates comprise a porous core material, which may be one or more of perlite, vermiculite, hollow microspheres, expanded polystyrene, or charcoal. Forming at least one layer of shell layer material on the core material, wherein the shell layer material comprises one or more of blast furnace slag particles, fly ash, hollow microspheres, recycled concrete powder, recycled glass powder or charcoal powder. The high-strength lightweight core-shell aggregate of the present invention has a loose bulk density of less than about 980 kg/m < 3 >, a compressive strength of greater than about 4 MPa, a water absorption of less than 20%, and a carbon emission of about 181 kg carbon dioxide equivalent (kgCO2eq) or less per ton. Lightweight concrete having a density of 1900 kg/m < 3 > or less is formed by mixing high strength, lightweight core-shell aggregate with cement.
本发明提供一种利用废料制成的高强度、轻质核壳型骨料。这些骨料包含多孔核心材料，该多孔核心材料可以是珍珠岩、蛭石、中空微球、膨胀聚苯乙烯或生物炭中的一个或多个。在核心材料上形成至少一层壳层材料，其中包括高炉矿渣颗粒、粉煤灰、中空微球、再生混凝土粉末、再生玻璃粉末或生物炭粉末中的一种或多种。本发明高强度、轻质核壳型骨料的松散堆积密度小于约980千克/立方米，抗压强度大于约4兆帕，吸水率小于20％，碳排放量约为每吨含181或更低的千克二氧化碳当量(kgCO2eq)。通过将高强度、轻质核壳型骨料与水泥混合形成轻质混凝土，其密度为1900千克/立方米或更低。
