Class III coarse aggregate prepared from river sludge and applied to municipal roads and preparation method of class III coarse aggregate
The invention provides class-III coarse aggregate prepared from river sludge and applied to municipal roads. The class-III coarse aggregate is prepared from the following components in parts by weight: 60-80 parts of river sludge, 6-10 parts of water glass, 4-8 parts of needle-like Al2O3 sol, 10-15 parts of fly ash and 4-6 parts of a flaky SiO2 sol fiber net. According to the class III coarse aggregate disclosed by the invention, traditional clay and shale are replaced by wastes such as river sludge and fly ash for firing, so that the problems of energy shortage and waste recovery are solved, and the prepared novel recycled coarse aggregate can reach the standard of the class III coarse aggregate.
本发明提供了一种利用河道淤泥制作应用于市政道路Ⅲ类粗骨料，包括以下重量份组分：河道淤泥60‑80份，水玻璃6‑10份，针状Al2O3溶胶4‑8份，粉煤灰10‑15份，片状SiO2溶胶纤维网4‑6份。本发明Ⅲ类粗骨料利用河道淤泥、粉煤灰等废料来替代传统的黏土和页岩烧制，解决了能源紧缺问题和废料回收问题，且制备出来的新型再生粗骨料可达到Ⅲ粗骨料的标准。
