Problems solved by technology

Using high-concentration strong alkali and alkali metal silicates and carbonates as activators to activate slag powder to make alkali-activated slag cement was first invented by Ukrainian scientist Glukhovsky in 1957. It has many silicates Cement does not have excellent properties, such as early strength and high strength, low water demand,

Abstract

The invention discloses composite ecological cement produced by using reproducible biomass combustion wastes, industrial residues and the like as main raw materials (the utilization ratio of the biomass combustion wastes and the industrial residues is over 80 percent). The novel gelling material namely the composite ecological cement is combined with other environment-friendly materials such as a paper honeycomb panel and the like to compound and manufacture a novel environment-friendly building product, such as a novel super-lightweight high-strength inner wall composite partition plate (having a dead weight of about 19 kilograms per square meter) special for novel high-rise and multi-layer frame constructions, a 65 percent self-heat preservation lightweight high-strength outer wall partition plate, an outer wall heat preservation and decoration integrative plate, a novel composite wood building block, a novel composite baking-free brick, novel bubble concrete and the like; and all the products are detected by a national level building material detection institution, reach a related product quality standard, are manufactured in factory by using specified machinery, are mounted and manufactured on site and are efficient and economical. The composite ecological cement uses various reproducible resources and various reclaimable wastes to the utmost extent, protects the environment, saves energy, reduces discharge and the overall comprehensive engineering manufacturing cost, and has important economic and social benefits.
