Abstract
The invention belongs to the technical field of building materials and construction, and particularly relates to anti-cracking plastering mortar.The anti-cracking plastering mortar is prepared from, by weight, 200-220 parts of ordinary Portland cement, 780-800 parts of engineering sand, 1-1.5 parts of polypropylene fibers and 0.5-0.6 part of ordinary mortar additive.The anti-cracking plastering mortar has a good application property and water-retaining property, and can be widely applied to building walls.Compared with traditional products or existing products, a three-dimensional disordered distribution net bearing function can be formed in concrete, and microcracks formed at the preliminary hardening stage of a cement product are blocked in the development process and can hardly further develop.Therefore, the breaking tenacity of the cement product can be improved, the anti-cracking and anti-seepage performance of the cement product is improved, and the anti-cracking plastering mortar is a novel ideal anti-cracking, anti-seepage, abrasion resisting and heat preserving material in the mortar and concrete work.
Description
Technical field
The invention belongs to construction material and technical field of construction, be specifically related to a kind of cracking resistance motar.
Background technology
Along with the continuous propelling of China's construction material reform, substantial amounts of novel wall material is widely used, and defines the materials for wall structural system taken as the leading factor with walling unit.Walling unit water absorption is strong, contractility is big, mixing water in mortar is quickly siphoned away by materials for wall, and traditional motar workability, poor water retention property, adhesion strength is low, there is cracking, the problems such as dry linting, the quality of building can be had a strong impact on, therefore traditional motar can not meet existing wall plastering construction requirement along with the fast development of market economy and improving constantly of people's living standard, dwelling construction maintains the impetus of fast development, meanwhile, people increasingly advocate comfortableization of living environment, superior and gracefulization, numerous residents will carry out finishing in various degree before moving house, to create grace, comfortable living environment, this has just driven decorations upsurge and the modern rise of inside plant.
Owing to traditional motar application property in various building blocks is poor, low with building block adhesion strength and dried easily cracking, have a strong impact on construction quality, therefore also urgently need one can mechanical execution, crack resistance good, there is better adhesion strength and the motar of low drying shrinkage, improve the cracking resistance of overall metope, it is to avoid the generation of various crackings in various degree.
Summary of the invention
For solving the deficiencies in the prior art, the invention provides a kind of cracking resistance motar, it has significantly high cracking resistance, spread upon buildings or structures surface, and can be suitably used for the block material of currently the majority, concrete wall surface etc., crack can be reduced, make building strengthen intensity, strengthen anti-permeability performance, more attractive in appearance.
A kind of cracking resistance motar, including each component of following weight portion: the Portland cement of 200～220 parts, the engineering sand of 780～800 parts, the polypropylene fibre of 1～1.5 part, the ordinary mortar additive of 0.5～0.6 part.
Concrete, the diameter of polypropylene fibre is 10～30 μm, and length is 8～12mm.
Concrete, described engineering sand is any one or a few the mixture in quartz sand, dolomite sand, natural river sand or mechanism quartz sand.
Preferably, the modulus of fineness of described engineering sand is 2.0～3.0, and particle diameter is less than 4.75mm, and clay content is less than 5.0%, and clod content is less than 2.0%.
It is furthermore preferred that the water content of described engineering sand is less than 0.5%.
Concrete, described Portland cement is P I 42.5 higher level portland cement, P II 42.5 higher level portland cement or P O42.5 higher level portland cement.
Concrete, described ordinary mortar additive includes cellulose ether, starch ether and air entraining agent, carries out thickening water conservation.
The cracking resistance motar that this provides, there is good application property, water-retaining property, can be widely applied to building wall, relative to tradition or existing product, it can form the netted support effect of three-dimensional random distribution in concrete, makes cement products be stopped in evolution at the micro-crack that the hardening initial stage is formed, it is difficult to develop further.Thus the fracture toughness of cement products can be improved, improve the anti-crack and anti-seepage performance of cement products, be mortar, concrete works cracking resistance, antiseepage, wear-resisting, insulation new type ideal material.
Detailed description of the invention
Hereinafter principles of the invention and feature being described, example is served only for explaining the present invention, is not intended to limit the scope of the present invention.
