Low-strength lightweight concrete prepared from bulk solid wastes
The invention discloses low-strength lightweight concrete prepared from bulk solid wastes. The low-strength lightweight concrete is prepared from the following components in percentage by mass: 5.8 to 8.7 percent of ordinary Portland cement, 8.7 to 11.9 percent of III-grade fly ash, 18.3 to 20.4 percent of shell fine materials, 17.2 to 20.4 percent of red slag fine materials, 25.0 to 28.6 percent of brick-concrete recycled coarse materials, 14.0 to 17.2 percent of mixing water, 1.5 to 1.7 percent of additional water, 0.86 to 1.18 percent of foam and 0.046 to 0.059 percent of foam stabilizer. And by reasonably controlling the mixing ratio, the requirements of various backfill projects on working performance and mechanical performance can be met. According to the invention, various solid waste materials such as waste shells, red slag and brick-concrete construction wastes are co-processed and digested, and conditions are provided for high working performance of the low-strength lightweight concrete; the additional value of waste is fully excavated, and social, economic and environment-friendly benefits are improved; and the method is green, low-carbon, energy-saving and emission-reducing, and the cost is obviously
本发明公开了一种利用大宗固废制备的低强度轻质混凝土,包括如下按质量百分计的组分:普通硅酸盐水泥5.8~8.7%、Ⅲ级粉煤灰8.7~11.9%、贝壳细料18.3~20.4%、红渣细料17.2~20.4%、砖混类再生粗料25.0~28.6%、拌合水14.0~17.2%、附加水1.5~1.7%、泡沫0.86~1.18%、稳泡剂0.046~0.059%。通过对配合比的合理控制,可满足各类回填工程对工作性能、力学性能的要求。本发明协同处置与消纳废弃贝壳、红渣、砖混类建筑垃圾等多种固废材料,为低强度轻质混凝土较高的工作性能提供条件;充分挖掘废弃物的附加值,提高社会经济环保效益;绿色、低碳,节能减排,显著降低成本。
