Shrinkage property is a significant indicator of the durability concrete, and shrinkage green recycled concrete particularly problematic. In this paper, construction waste was crushed screened to generate simple-crushed coarse aggregate (SCRCA). The SCRCA then subjected particle shaping create primary particle-shaped (PPRCA). On basis, PPRCA again obtain secondary (SPRCA). Under conditions where dosage cementitious material 300 kg/m3 sand rate 38%, new high-belite sulphoaluminate cement...
Green recycled aggregate concrete (RAC) with high strength and low shrinkage is prepared based on coarse produced by the particle-shaping aggregate-strengthening method green low-carbon new cement. This not only effectively alleviates shortage of natural resources, but also improves performance concrete, which great significance for multi-channel resource utilization construction waste. In this study, three kinds aggregates (RCA), including simple crushing (JD-RCA), one-time (KL-RCA)...
Alkaline electrolyzed water, a kind of clean green water with excellent characteristics such as high activity, strong alkalinity, ion penetrating ability, electrical charge, and good molecule adsorption, was significant to the resource utilization industrial fly ash waste. This paper studies highly active potassium-based alkaline water's impact, compared ordinary on cement hydration process using microstructural methods heat test, differential thermal analysis, X-ray diffraction (XRD)...
