The utilization of coal gangue (CG) as a substitute for cement in building materials offers an effective solution to mitigate resource wastage and environmental pollution caused by CG accumulation while also reducing carbon dioxide (CO2) emissions. This paper employs orthogonal experiments to examine the effects of CG content. water/binder ratio (w/b). and foam content on the mechanical. https://herbsdailyes.shop/product-category/face-creams/
