Abstract

The invention relates to building polymer powder based on composite silicate, comprising the components in percentage by weight: 35-45wt% of fly ash, 20-30wt% of granulated blast-furnace slag micro powder, 25-35wt% of Portland cement or common Portland cement, 3-5wt% of limestone powder and/or calcium hydroxide and 4-5wt% of sulfate or gypsum powder. The specific surface area of the thinness of the components ranges from 280 to 340; and the specific surface area of the building polymer powder based on the composite silicate ranges from 470 to 500. The production process can be an intermittent grinding system generating process or a continuous grinding system generating process. The polymer powder has favorable stability, operation, mechanical properties, durability, no corrosion or radiation, low use price which is 45-50% lower that that of cement, small specific gravity, and great size which is approximately 15% larger than that of common Portland cement when weights are same.

Description

Technical field:

[0001] The invention relates to a composite silicate-based building polymer powder, which belongs to the field of building materials. technical background:

[0002] At present, the poor structure of the cement industry has brought many negative effects, such as high energy consumption, large carbon dioxide emissions, serious environmental pollution, a large amount of waste of geological resources, and low productivity. Random mining has caused great damage to mines, land resources and vegetation. The phenomenon of destruction and soil removal is more serious, and the pollution of waste gas and dust from cement enterprises is the most serious. Most cement plants have become major polluters today, seriously affecting the urban and rural environment and agricultural production. Cement dust pollution sources include limestone mining and crushing, transportation, storage, packaging, drying, raw material grinding, clinker calcination process and cooling process, coal ...
