NOVELTY - Regenerated concrete comprises 920-980 pts. wt. regenerated aggregate, 70-130 pts. wt. cement, 0.84-1.6 pts. wt. nano-reinforced liquid, 35-75 pts. wt. water, 0.84-1.8 pts. wt. steel fiber-polyvinyl alcohol mixed fiber, 4.5-9.3 pts. wt. waste textile fiber, 0.7-1.3 pts. wt. carborundum, 10-16 pts. wt. soybean protein powder, and 4-8 pts. wt. trehalose. The nano-reinforced liquid is a mixed solution of nano-silica, nano-alumina, nano-calcium carbonate, nano-graphene and water reducing agent. The waste textile fiber comprises waste polyester fiber, waste cotton fiber and waste glass fiber in a ratio of (1-1.1): (0.8-1.0): (1.0-1.3). The water reducing agent is polycarboxylic acid water reducing agent. USE - Used as regenerated concrete. ADVANTAGE - The regenerated concrete has small porosity, high density, and strong mechanical property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the regenerated concrete.
