In one example embodiment of the invention discloses a preparation method of aggregates, the method includes silicon aluminum scrap from combustion ash mixed sludge wastewater treatment equipment and non coal, the mixture is agglomerated to form agglomerates, and the high-temperature processing of agglomerates to form aggregates. For example, the waste can include city solid waste incineration incinerator bottom ash, fly ash, cement kiln incinerator filter dust, dust, waste glass, blast furnace slag, kiln dust and / or granite sawing residue. The method may further include grinding the waste prior to mixing. Preferably, the grinding is wet grinding. High temperature processing of agglomerates can be carried out in a rotary kiln. The resulting aggregates may be light weight or normal weight, sintered or vitrified aggregates. Methods of making aggregates and aggregates of high and low calcium aluminosilicate materials are also disclosed.
