Abstract

The invention relates to a cement-based abrasion-resistant material for a concrete floor, and particularly relates to a cement-based abrasion-resistant material for an II type concrete floor. The cement-based abrasion-resistant material is prepared from the following substances in parts by weight: 35-50 parts of ordinary portland cement, 20-40 parts of silicon carbide, 5-20 parts of steel slag, 0.5-3 parts of redispersible latex powder, 0.15-0.35 part of water reducing agents, 1-15 parts of silicon ash, 0.05-0.15 part of cellulose compounds and 5-15 parts of fly ash. The cement-based abrasion-resistant material disclosed by the invention is compounded from common building raw materials, chemical raw materials and industrial waste residues, has the advantages of easiness for obtaining raw materials, sufficiency in supply, low toxicity, no volatilization, simplicity for processing and preparation and low cost. Various indexes of the cement-based abrasion-resistant material all meet the requirements of the cement-based abrasion-resistant material for the II type concrete floor in a JCT 906-2002 'a cement-based abrasion-resistant material for a concrete floor' standard. The cement-based abrasion-resistant material disclosed by the invention can be used for well solving the problem of surface weak layer of the traditional concrete floor and has the advantages of high strength and high abrasion-resistant property.

Description

technical field [0001] The invention relates to a cement-based wear-resistant material for concrete floors, in particular to a type II cement-based wear-resistant material for concrete floors. Background technique [0002] In order to solve the problem of the weak layer on the surface of the concrete floor and overcome the disadvantages of the terrazzo floor, the British invented the cement-based wear-resistant material for the concrete floor. dry mix materials. Due to its advantages of low cost, fast construction, compression resistance, impact resistance, and wear resistance, it is widely used in parking lots, warehouses, highways, docks and other places with heavy friction, easy damage and high impact force. my country's current standard JCT906-2002 "Cement-based wear-resistant materials for concrete floors" divides wear-resistant materials into two types: type I and type II according to aggregate types. The wear-resistant aggregate used in type II wear-resistant materia...
