Highly durable composite and manufacturing thereof

摘要

Lithium compound functionalized carbonaceous materials are dispersed in a homogenous aqueous mixture. The mixture is dispersed in water used to mix cement and aggregate and remain dispersed in the cement. Spraying the aqueous mixture over cracked or damaged concrete surfaces fill the cracks or damages with the functionalized nanotubes. The solution solves problems of concrete permeability, eliminates alkali-silica reactions, avoids shrinkage and thermal stress and improves durability of concrete.
