Embodiment 1

[0011] A kind of dry powder cement, the main components are phosphorus slag, boiler slag, waste clinker and gypsum produced in the production of calcium aluminate powder and mixed in proportion, and after mixing, use a ball mill to grind it into ultrafine powder. The components are composed as follows in percentages and parts : Phosphorus slag 30%, boiler slag 25%, waste clinker produced in the production of calcium aluminate powder 40%, gypsum 5%.

Embodiment 2

[0013] A kind of dry powder cement, the main components are phosphorus slag, boiler slag, waste clinker and gypsum produced in the production of calcium aluminate powder and mixed in proportion, after mixing, use a ball mill to grind into ultrafine powder: phosphorus slag 35%, boiler slag 29% %, 35% of waste clinker produced in the production of calcium aluminate powder, and 1% of gypsum.

[0014] Known by embodiment 1 and embodiment 2, above-mentioned embodiment 1 and embodiment 2 are used to paint on the exterior wall, and it and ordinary cement are painted on the exterior wall to get table 1,

[0015] Table 1 Example 1, Example 2 and common cement are used in the contrast effect of external wall painting under the same environment and conditions

[0016]

[0017]

[0018] As can be seen from Table 1, when the dry powder mortar of the present invention is used on the outer wall, it has better acid and corrosion resistance than ordinary cement, good fire prevention effe...

Abstract

The invention relates to the technical field of an environmentally-friendly material, in particular to dry powder plaster. The main component is obtained by mixing phosphorus slag, boiler slag, waste clinker generated by production of calcium aluminate and gypsum according to the proportion and grinding the mixture into ultrafine powder by a ball mill; the component consists of the following raw materials in percentage by weight: 30 to 35 percent of phosphorus slag, 25 to 29 percent of boiler slag, 35 to 40 percent of waste clinker generated by production of calcium aluminate and 1 to 5 percent of gypsum. The dry powder plaster has the advantages of wide application range, waste material recyclability, low production cost and high heat-insulating, fire-resistant, acid-resistant and corrosion-resistant properties.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to dry powder cement. Background technique [0002] Using natural rock or industrial waste as the main raw material, it is a non-metallic industrial material with regular crystal arrangement, hard texture and fine texture made by batching, melting, pouring, heat treatment and other processes. Cast stone has good corrosion resistance and wear resistance, but its toughness and impact resistance are poor, and cutting is difficult. Cast stone products mainly include cast stone pipes, cast stone composite pipes, cast stone slabs and cast stone materials, which have been widely used in severe wear and corrosion parts in electric power, coal, mining, metallurgy, chemical industry, construction and other industrial sectors. It can prolong the service life of parts or equipment by ten times or even dozens of times that of other materials. [0003] Due to the poor toughness and h...
