Characteristics of Foamed Concrete Containing Ultra-fine Drift Sand of the Yangtze River

The primary goal of this study was to evaluate the use Ultra-fine Drift Sand from Yangtze River (China) in place natural sand production foamed concrete. experimental design included factors with varying levels: proportion at four levels (0 percent, 30%, 60%, and 100%). substituted mass material. Each factor's effect on compressive strength, density (dry saturated), air voids, water absorption assessed. According results, all had significant findings. strength concrete increased due an increase curing time; fly ash content up 30%; increasing percent Yangzi river sand; decreasing slag. mixture 10% SF (Silica Fume), 24% FA (Fly Ash) 100% YS (Yangzi soil) gives enhanced results by which it reaches about 7 MPa compared other remaining percentages mixing benefit compression results. This method treatment provides economical way through providing a cheap material that enhances mechanical properties concrete, light weight good isolator improve building's thermal insulation reduce ecological problems save energy.
