Solid wastes have been widely used as a cement substitute in precast concrete. On the one hand, solid waste can effectively ameliorate series of problems caused by steam curing. other use reduce amount construction industry and carbon emissions. However, due to complexity curing system, performance concrete prepared under different conditions varies greatly. Moreover, there are wide variety wastes, differences physicochemical properties significant. Therefore, it is necessary systematically determine mechanism action commonly wastes. In this paper, system introduced detail, summarized. It was found that an appropriate increase temperature duration facilitates strength development addition, difference effect addition on early late concrete, which usually leads decrease demolding but increases This study provides reference for rationally regulating systems realizing comprehensive utilization

NH4+-N and Low Ratios of NH4+-N/NO3−-N Promote the Remediation Efficiency of Salix linearistipularis in Cd- and Pb-Contaminated Soil

(1) Background: the utilization of fast-growing trees for phytoremediation in heavy-metal-contaminated soil is increasingly recognized as an effective remediation method. Nitrogen (N) fertilizer enhances plant tolerance to heavy metals, yet impact various N levels and ammonium (NH4+-N)/nitrate (NO3−-N) ratios on cadmium (Cd) lead (Pb) by remains unclear. (2) Methods: efficiency Salix linearistipularis remediating Cd- Pb-contaminated was investigated using a pot experiment with three (60, 120, 200 kg hm−1 year−1) five NH4+-N/NO3−-N (6/0, 4/2, 3/3, 2/4, 0/6) employed, resulting 16 treatments including control. (3) Results: significantly affected Cd Pb uptake S. linearistipularis. The highest increases were observed N120-6/0 treatment, which increased 104.36% 95.23%, respectively. In addition, stem leaf bioconcentration factors enhanced 28.66% 40.11%, Structural equation modeling revealed that predominantly influenced traits (biomass root traits) rather than properties. (4) Conclusions: Our findings highlight potential ratio regulate traits, thereby improving soil.
