Lightweight sintering-free aggregate prepared from solid waste and preparation method of lightweight sintering-free aggregate
The invention relates to a light sintering-free aggregate using solid waste and a preparation method thereof. The light sintering-free aggregate comprises an outer shell layer, an inner shell layer and a light porous concrete core material which are sequentially arranged from outside to inside; the lightweight porous concrete core material comprises the following raw materials in parts by mass: 5-10 parts of cement, 10-25 parts of an admixture, 55-80 parts of solid waste powder, 1-3 parts of a foaming agent and 0-10 parts of a functional auxiliary material, the inner shell layer is prepared from the following raw materials in parts by mass: 5 to 15 parts of cement, 10 to 25 parts of admixture, 64 to 82 parts of solid waste powder and 2 to 6 parts of tackifier; the shell layer is prepared from the following raw materials in parts by mass: 10 to 20 parts of cement, 20 to 30 parts of admixture and 50 to 70 parts of solid waste powder. The three-layer structure is arranged, solid waste utilization is achieved, and the high-strength unfired lightweight aggregate is obtained.
本发明涉及一种利用固废的轻质免烧结骨料及其制备方法，包括由外及内依次设置的外壳层、内壳层和轻质多孔混凝土芯材三层结构；轻质多孔混凝土芯材的原料按质量份数包括：水泥5～10份、掺合料10～25份、固废粉料55～80份、发泡剂1～3份以及功能辅助材料0～10份；所述内壳层的原料按质量份数包括：水泥5～15份、掺合料10～25份、固废粉料64～82份和增粘剂2～6份；所述外壳层的原料按质量份数包括水泥10～20份、掺合料20～30份和固废粉料50～70份。本发明设置三层结构，实现了固废利用，获得高强免烧轻质骨料。
