Abstract
The invention discloses an abrasion-resistant cement-based self-leveling mortar.The abrasion-resistant cement-based self-leveling mortar is prepared by mixing ordinary Portland cement, high alumina cement, quartz sand, coarse whiting powder, anhydrite powder, an early strength agent, a water reducing agent, a retarder, a defoaming agent, dispersible latex powder, a water retention agent and an abrasion-resisting agent.The abrasion-resistant cement-based self-leveling mortar uses the high alumina cement and the ordinary Portland cement as binding materials in a compounded mode and uses the anhydrite powder to produce irreversible expansion in the cement condensation hardening process and prevent later shrinkage of the mortar.The abrasion-resisting agent improved by a foaming agent is also added in the composition, the apparent density of the abrasion-resisting agent is moderate, and the abrasion-resisting agent does not result in accumulation and sedimentation when being used in the self-leveling mortar and can be evenly distributed.In addition, a porous structure can be fully bonded and infiltrated with auxiliary materials, an admixture and base layer concrete and makes the abrasion resistance of the floor surface of the self-leveling mortar improved greatly.The application range of the self-leveling mortar in warehouses, underground parking garages and other places is widened.
Description
Technical field
The present invention relates to a kind of building mortar, be specifically related to a kind of wear-resisting cement-based self-leveling mortar.
Background technology
Cement-based self-leveling mortar refers to the pulverulent material being made up of cement-based gelling material, fine aggregate, filler and additive etc., through with water or emulsion mix and blend after there is the floor leveling mortar of certain fluidity.In recent years, self-leveling cement serves not only as self-leveling material have been had and has been widely applied, and is also obtaining as on finish earth material
Bigger development, some surfacing self-leveling floor cement obtain market accreditation with the Surface Engineering effect that its flat smooth, color are more consistent, in underground parking, workshop, warehouse, market, exhibition room, office building and commercial and residential building etc. be obtained for application.
Cement-based self-leveling mortar is as finish earth material, and surface abrasion resistance is an important index.Surface layer cement-based self-leveling mortar needs to meet the requirement of a lot of high-performance aspect: such as high fluidity, high-strength and early strong, ungauged regions, smooth etc. without bleeding, smooth surface, reach these performance requirements, need raw material is carried out careful screening, formula is optimized, just can develop high performance gravity flowing levelling mortar.
Summary of the invention
Present invention aim at the deficiency for existing cement-based self-leveling mortar, it is provided that a kind of wearability is good, high fluidity, ungauged regions, and intensity is high, the gravity flowing levelling mortar formula of the advantages such as smooth surface, and the technical solution adopted in the present invention is:
A kind of wear-resisting cement-based self-leveling mortar, it is characterised in that formed by following components mixed preparing by weight percentage:
Portland cement 20-35 part
Alumina cement 5-10 part
Quartz sand 30-45 part
Dicalcium powder 5-10 part
Anhydrite powder 5-10 part
Early strength agent 1.5-2.8 part
Water reducer 0.5-1.0 part
Retarder 0.2-0.5 part
Defoamer 0.2-0.5 part
Polymer dispersion powder 1-5 part
Water-retaining agent 0.2-0.5 part
Anti-wear agent 8-15 part.
As the present invention further improvement, described early strength agent is sodium sulfate, and calcium formate is that 1:2 mixes according to percentage by weight.
As the present invention further improvement, described water reducer is poly carboxylic acid series water reducer.
As the present invention further improvement, described water-retaining agent viscosity is at the hydroxyethyl methyl of 1.5-4.5 ten thousand mpa.s
Cellulose ether.
As the present invention further improvement, described anti-wear agent is that ferrum adds apparent density that foaming agent makes at 2700kg/m under 1500 DEG C of high temperature3Foam iron ore.
The present invention provides the benefit that relative to prior art: the wear-resisting cement-based self-leveling mortar of the present invention, uses alumina cement and Portland cement compound as Binder Materials, it is achieved that mortar condenses hardening and early strength.Employ anhydrite powder so that cement setting hardening process produces irreversible microdilatancy, it is prevented that the contraction in mortar later stage.Early strength agent, retarder, effectively control the setting time of mortar and improve the early strength of mortar, water-retaining agent, defoamer, polymer dispersion powder etc. substantially improves application property and the degree of compaction of mortar.Formula also added the foamed dose of anti-wear agent improved, its apparent density is moderate, gravity flowing levelling mortar uses and does not result in accumulation and sedimentation, can be uniformly distributed, simultaneously, loose structure can well-bonded with adjuvant, additive and basal layer concrete, infiltration, make gravity flowing levelling mortar terrace surface wearability be greatly improved.Expand gravity flowing levelling mortar in warehouse, the application in the places such as underground parking.
