Experimental Verification of Use of Secondary Raw Materials as Fillers in Epoxy Polymer Concreteone of the most widely used fillers in PC. Silica sand is the primary raw material and its replacement by some progressive secondary raw materials could be appropriate if PC shows the same or better physical and mechanical properties. In this paper, the possibility of using secondary raw materials shegemony 发表于 2025-3-25 12:52:04

Polymer Solutions for Protection of Concrete Exposed to Strong Alkaline or Acid Effluent on Industrifailure, piping leaks, control mishandling, etc.). Besides chemical tanks specifically designed for long-term storage, surrounding concrete retention basins are generally not protected properly against unexpected exposure to aggressive solutions. This raises concerns for environmental protection aga瘙痒 发表于 2025-3-25 23:39:42
