Full-machine-made sand wet-mixed mortar and processing method thereof
The invention provides full-machine-made sand wet-mixed mortar, which comprises the following components in parts by weight: 180-200 parts of cement, 18-22 parts of fly ash, 8-12 parts of limestone powder, 8-12 parts of semi-hydrated gypsum, 18-22 parts of vitrified micro beads, 180-220 parts of water, 3-7 parts of an additive, 20-30 parts of activated sludge and 1200-1600 parts of machine-made sand, wherein the water is from starch slurry waste liquid with the starch content of 8-12%, and the additive comprises 3% of amylase, 5% of latex powder, 2% of lauryl sodium sulfate and 90% of sodium gluconate. The invention further provides a processing method of the wet-mixed mortar, wherein starch production wastewater and activated sludge generated in urban life are utilized, so that secondarypollution of the starch industry and the activated sludge to the environment is avoided, and a large amount of waste materials can be consumed while the production cost is reduced. According to the invention, additives used in the production process are simple in component, can be purchased in the market, do not affect normal production of enterprises and can be popularized in wet-mixed mortar enterprises; and a full-machine-made sand formula is used, so that river ecology is not damaged.
本发明提供了一种全机制砂湿拌砂浆，其依重量计，包括以下：180～200份水泥、18～22份粉煤灰、8～12份石灰石粉、8～12份半水石膏、18～22份玻化微珠、180～220份水、3～7份外加剂、20～30份活性污泥和1200～1600份机制砂；所述水来自于其中淀粉含量为8～12％的淀粉浆废液；所述外加剂包括3％的淀粉酶、5％的乳胶粉、2％的十二烷基硫酸钠、90％的葡萄糖酸钠。本发明还提供了该湿拌砂浆的加工方法，其中利用了淀粉生产废水以及城市生活产生的活性污泥，避免淀粉工业、以及活性污泥对环境造成二次污染；降低生产成本的同时能够大量消耗废弃物料；生产过程中使用的外加剂成分简单，可以市售购得，不会影响企业的正常生产，能够在湿拌砂浆企业中得以推广；使用全机制砂配方，不会对河流生态造成破坏。
