Abstract
The invention discloses anti-crack anti-freezing cement mortar. The anti-crack anti-freezing cement mortar is prepared by mixing coal ash, silicon ash, quartz sand, an early strength agent, a water reducing agent, water, fiber and a thickening agent. According to the anti-crack anti-freezing cement mortar provided by the invention, the common silicic acid serves as a main cementing material, and auxiliary materials such as the coal ash and the silicon ash are used cooperatively, so that the strength of the mortar is effectively improved; the quartz sand with different grain size are used in a matched way, and a proper amount of water-reducing agent, thickening agent and the early strength agent are added, so the porosity of the mortar is reduced and the earth strength of the mortar is improved; high-quality polyvinyl alcohol fiber and cement are added, so that high affinity and excellent alkali resistance and weather resistance are achieved, and crack caused by plastic shrinkage of the mortar and temperature change can be effectively controlled; moreover, the impact resistance, the permeation resistance and the anti-freezing property of the cement mortar are improved, and the anti-crack anti-freezing cement mortar can be widely applied to water conservancy project, roads and bridges, ports and piers and the like.
Description
Technical field
The present invention relates to building materials field, and in particular to a kind of cracking resistance antifreezing cement mortar.
Background technology
Cement mortar structure its durability is always the big problem that engineering field is badly in need of solving.Cement-base composite material exists
The numerous areas application prospects such as road and bridge construction are extremely wide.Main application steel fibre domestic at present, glass fibre, carbon
Fiber, polypropylene fibre increase cement mortar, but the problems such as there is bad dispersibility, constructional difficulties, high cost.
The content of the invention
Present invention aim at, there is provided a kind of cracking resistance antifreezing cement mortar, the technical solution adopted by the present invention is as follows：
A kind of cracking resistance antifreezing cement mortar, is mixed with and formed by weight percentage by following components：
Portland cement 15-35 parts
Flyash 5-10 parts
Silicon ash 1-10 parts
Quartz sand 20-40 parts
Early strength agent 0.5-2 parts
Water reducer 1-3 parts
Water 20-50 parts
Fiber 2-10 parts
Thickener 0.5-2 parts.
One of preferably, described quartz sand is mixed with the quartz sand of 90-120 mesh in 30-70 mesh quartz sand by particle diameter
Conjunction is formed.
One of preferably, described early strength agent is calcium formate.
One of preferably, described fiber be intensity in 15-20CN/dtex, modulus is in the poly- of 12-18GPa
Alcohol fibers.
One of preferably, described thickener is by the hydroxypropyl methyl cellulose ether and hydroxypropyl of 200,000 mpa.s
Base starch ether is 5 according to weight ratio:1 mixing composition.
The present invention is relative to the beneficial effect of prior art：Cracking resistance antifreezing cement mortar of the invention, with common silicic acid
As main Binder Materials, and with the use of flyash, the auxiliary material such as silicon ash effectively improves the intensity of mortar, different
The quartz sand collocation of particle diameter is used, and adds appropriate water reducer, thickener, early strength agent so that mortar porosity declines, and improves
The early strength of mortar, the vinal and cement for adding high-quality has a good affine performance, alkaline-resisting against weather
Mortar plastic shrinkage, the crackle caused by temperature change can be effectively preferably controlled, while cement mortar impact resistance is lifted,
Impermeability, and freeze-proof, can be widely applied to the places such as hydraulic engineering, road and bridge, port and pier.
