Ecological ultra-high performance concrete incorporating multi-scale and multi-source solid wastes as nano-micron filler, ultrafine binder and fine aggregate
Original language description
Ultra-high performance concrete (UHPC) is a typical material composed of fine raw materials of high quality, such as silica fume (SF) and quartz sand (QS), and has a high content of cement, which result in high cost and carbon emissions. In present work, a low-cost and ecological UHPC was prepared with multi-scale and multi- source solid wastes as nano-micron filler, ultrafine binder and fine aggregate. The nano-micron grade waste autoclaved aerated concrete (WSA) and micron grade ultrafine GGBS (UGGBS) were prepared to replace the original SF and ordinary slag respectively, and QS was replaced by iron tailings (IT). The amount of solid wastes in the prepared green UHPC is as high as 42 %, and the compressive strength at 28 d reached 156.8 MPa, which is higher than that reported in previous literatures. The main hydration peak is advanced and strengthened, and the microstructure of UHPC is refined by the synergistic effect of solid wastes with different fineness grades. Under similar carbon emission, green UHPC prepared from multi-source solid waste has higher compressive and flexural strength. The cost of UHPC with multi-scale and multi-source solid wastes was 21 % lower than that of single solid waste group and 30 % lower than that of reference group without substitution.
