Geopolymer as a new type of alkali excitation gel material, can use natural minerals containing aluminate silica (kaolin), industrial solid waste (fly ash, slag, steel slag, red mud, etc.) as the main material, through the alkali agent, first after the formation of condensation with three-dimensional space mesh structure of polysilicate aluminate gel material.
Performance advantage
Early strength, fast hardening, high strength, seepage resistance, corrosion resistance, heat insulation, high temperature resistance, good stability.
Compared with cement, the production process of Geopolymer reduces the emission of CO2, energy saving and environmental protection, and has the advantages of fast hardening speed and high early strength.
Application in cementitious materials
Due to its own early strength and fast hard characteristics, especially suitable for fast demolding gel materials; suitable for making GRC plate, easy to form.
Due to its early strength and high interface bonding strength, it can be used as a rapid repair material for concrete structure.
As a polymer based coating, the polymer hydration structure is dense, with good waterproof, fire proof and other properties.
