▎ 摘 要
NOVELTY - A polyvinyl alcohol fiber (PVA)-and-graphene added high-strength concrete comprises PVA fiber, graphene, cement, water, sand, gravel, and water reducing agent. USE - Polyvinyl alcohol fiber-and-graphene added high-strength concrete. ADVANTAGE - The concrete is suitable for reinforcing construction of building structure, which can obviously enhance strength index of the concrete. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the pPolyvinyl alcohol fiber-and-graphene added high-strength concrete, which comprises adding PVA fiber and graphene into water, and uniformly mixing; pouring cement into rest water, using cement mixer to stir uniformly; pouring mixed solution of PVA fiber and graphene into the uniformly stirred cement, adding water reducing agent, uniformly mixing to obtain mixed solution A; finally pouring crushed stone and sand in the mixed solution A, and fully stirring to obtain high-strength concrete.
