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.

摘要: The present invention relates to a binder composition comprising a glass powder with a particle size of at least less than 0.15 mm and an alkali activator containing at least one alkali metal and at least one silicate. Preferably, a sodium silicate with a SiO2:Na2O weight ratio between about 1.6:1 to about 2.0:1. Mixed with water, the binder composition can be cured at ambient temperature, but rapidly yields a very high strength at an elevated temperature between about 40° C. to about 120° C. Preferably, between about 70° C. to about 90° C. The invention further provides a method of making artificial stone using glass as a sole binder and aggregate.
