Concrete waste slurry recycled lightweight aggregate as well as preparation method and application thereof
The invention discloses a concrete waste slurry recycled lightweight aggregate as well as a preparation method and application thereof. The concrete waste slurry recycled lightweight aggregate comprises the following components in parts by weight: 20-30 parts of Portland cement, 15-30 parts of glass beads, 20-40 parts of modified concrete waste slurry, 10-20 parts of silanized plant ash, 50-80 parts of water, 3-4 parts of a water reducing agent and 2-3 parts of triethanolamine. The modified concrete waste slurry is obtained by crushing concrete precipitate and activating the crushed concrete precipitate with acid. The recycled lightweight aggregate can be used for high consumption of concrete waste slurry, has good physical and chemical properties, can be used for preparing lightweight aggregate concrete and mortar products, and has a wide application prospect.
本发明公开了混凝土废浆再生轻骨料、其制备方法及应用，所述混凝土废浆再生轻骨料按重量份计组分包括：硅酸盐水泥20‑30份，玻化微珠15‑30份，改性混凝土废浆料20‑40份，硅烷化草木灰10‑20份，水50‑80份，减水剂3‑4份，三乙醇胺2‑3份；所述改性混凝土废浆料为混凝土沉淀经粉碎后使用酸活化得到。所述再生轻骨料能够高消纳混凝土废浆料，且具有良好的理化性能，可用于制备轻集料混凝土和砂浆类产品，应用前景广阔。
