Description

A kind of low-cost environmental-protecting mortar
Technical field
The invention belongs to building material technical fields, and in particular to a kind of low-cost environmental-protecting mortar.
Background technique
Mortar refers to inorganic coagulation material, fine aggregate, admixture, water, and is pressed according to the other components that performance determines The architecture engineering material of proper proportion cooperation, mixing and hardened formation, main the effects of playing bonding, liner and transmitting stress. Mortar is a kind of functional material, and an entirety is usually collectively formed with matrix, such as masonry mortar is to glue building block, brick bulk Become an entirety, common bearing load;For another example plastering mortar is applied to building substrate surface, in addition to obtaining smooth table Outside face, the effect of protection base is also acted as.Therefore, in addition to require mortar have certain intensity other than, also require mortar have compared with Good water-retaining property, crack resistance etc., increase the additive of water retentivity of mortar at present is at most cellulose ethers product, such Product has that price is high, influences mortar strength.Furthermore with the continuous increase of current construction scale, many places face The situation of natural sand scarcity of resources, and because river sand exploitation do great damage to riverbed and surrounding natural environment, part river Quicksand resource is prevented or restricted from exploitation, and river sand resource is increasingly in short supply.
Summary of the invention
In view of the above-mentioned problems, providing a kind of low-cost environmental-protecting mortar, which is replaced the present invention using part industrial residue River sand resource, and cellulose ethers are replaced with the lower lignocellulosic of price, reaching reduces cost, saves the mesh of natural resources 's.In order to achieve the above objectives, the present invention adopts the following technical scheme that.
A kind of low-cost environmental-protecting mortar, is made of the raw material of following parts by weight: 150-230 parts of ordinary portland cement, 30-80 parts of zeolite powder, 500-700 parts of ferronickel slag sand, 700-1000 parts of river sand, 0.2-0.5 parts of water-retaining admixture, slow setting early strength agent 0.5-2 parts, 0.15-0.3 parts of emulsifier op-10.
The zeolite powder by natural zeolite powder is milled to 45um and tails over to be obtained less than 12%.
The ferronickel slag sand is to be crushed to sand grains diameter by the waste residue generated in smelting ferronickel alloy process to obtain less than 4.75mm It arrives.
The water-retaining admixture is made of lignin fibre, cellulose ether and xanthan gum.
Preferably, the cellulose ether is carboxymethyl SE-cellulose ether or ethoxyl methyl cellulose ether.
Preferably, the lignin fibre is to pass through the organic fiber that chemical treatment obtains by straw.
It is furthermore preferred that the water-retaining admixture is by lignin fibre, carboxymethyl SE-cellulose ether and xanthan gum by weight Amount is formed than 1-3:1-2:1.
The slow setting early strength agent is made of sodium sulphate, calcium saccharate and dimethylethanolamine by weight 1-9:1-3:1.
Zeolite powder of the present invention is that natural zeolite is obtained after grinding, is one kind with SiO2And Al2O3Based on day Right mineral, can be with Ca (OH)2Reaction generates a series of hydrated product, has good pozzolanic activity.Due to ferronickel slag Formation temperature is higher, with certain hydration reaction activity under high alkali environment, there are the risk of certain alkali-aggregate reaction, Zeolite powder has excellent inhibition alkali-aggregate reaction performance, can effectively inhibit the generation of alkali-aggregate reaction.In addition, zeolite powder It is big to construct opening, there is many uniform cavities and ducts, in the energy adsorption moisture in mortar whipping process, reduction mortar Bleeding improves the water-retaining property of mortar.Ferronickel slag sand is different with the grain shape of river sand, and the present invention replaces river using part of nickel scum sand Sand can play the role of improvement plaster workability, improve mortar strength.Ferronickel slag sand is different with the water absorption rate of natural river sand, Particle of the partial size less than 0.075mm contains a large amount of clay, organic matter etc. in river sand, and water requirement is larger, and these substances influence The development of intensity.Broken ferronickel slag sand surface is relatively smooth, fine and close, and water absorption is small, can increase mortar mobility and consistency;River The rounder and more smooth smoothness of sand shape, and ferronickel slag sand is formed by Mechanical Crushing, has certain angular structures, makes to have between aggregate The mechanical engagement of effect is conducive to the compression strength for increasing mortar;Sand contains the mineral such as tricalcium silicate, dicalcium silicate in ferronickel slag, With certain hydration reaction activity, the interfacial structure of cementitious material Yu ferronickel slag sand can be improved, improve adhesion strength;Cellulose Ethers additive is the most obvious to the effect of mortar adhesiveness and adhesion strength, and mortar becomes viscous after incorporation, and adhesiveness improves, and glues Knotting strength improves, but compression strength is substantially reduced, and higher cost.Lignin fibre is the three dimensional network with obvious cross-linked effect Shape structure can improve the workability and cracking resistance of mortar with having preferable water imbibition, fiber reinforcement and thickening effect Performance is used in conjunction with cellulose ether, it is possible to reduce the dosage of cellulose ether improves mortar strength.Cellulose ether and lignin Fiber synergistic effect, reach water conservation, thickening, enhancing, cracking resistance optimum efficiency;Calcium saccharate itself has cement good slow Solidifying effect, with sodium sulphate and dimethylethanolamine it is compound after, can increase substantially the early strength of mortar, later strength also have compared with It is big to improve, overcome the problems, such as that later strength reduces after sodium sulphate is used alone.In addition, calcium saccharate is a kind of surfactant, It has good peptizaiton to cement granules, therefore can increase the workability and mobility of mortar, has certain diminishing Effect.Emulsifier op-10 can improve the emulsibility and foaming effect of mortar, improve the plumpness of mortar and use volume.
Two aspect below beneficial effects of the present invention major embodiment:
(1) mortar workability of the present invention is good, is easy to squeeze mix, plumpness and adhesion strength are high, the adhesiveness with masonry It can be good.
(2) present invention largely utilizes industrial solid castoff ferronickel slag, can help to dissolve processing ferronickel slag, reduce environment The problem of polluting, also solving the problem that natural sand shortage of resources, kills two birds with one stone.
