Description
Technical field
The invention belongs to building material technical field, and in particular to a kind of low-cost environmental-protecting mortar.
Background technology
Mortar refers to inorganic coagulation material, fine aggregate, admixture, water, and the other components determined according to performance are pressed
The architecture engineering material of proper proportion cooperation, mixing and hardened formation, main serve bonds, pads and transmitted stress etc..
Mortar is a kind of functional material, and an entirety is generally collectively formed with matrix, and such as masonry mortar is to glue building block, brick bulk
Become an entirety, common bearing load；For another example motar, is applied to building substrate surface, except obtaining smooth table
Outside face, the effect of protection basic unit is also acted as.Therefore, in addition to requiring mortar and there is certain intensity, also require mortar have compared with
Good water-retaining property, crack resistance etc., the additive of increase water retentivity of mortar is most for cellulose ethers product at present, such
The problem of there is high price, influence mortar strength in product.In addition with the continuous increase of current construction scale, many places face
The situation of natural sand scarcity of resources, and because river sand exploitation does great damage to riverbed and surrounding natural environment, part river
Quicksand resource is prevented or restricted from exploitation, river sand resource worsening shortages.
The content of the invention
The present invention is in view of the above-mentioned problems, provide a kind of low-cost environmental-protecting mortar, and the mortar is replaced using part industrial residue
River sand resource, and cellulose ethers is replaced with the relatively low lignocellulosic of price, reaching reduces cost, saves the mesh of natural resources
's.To reach above-mentioned purpose, the present invention is adopted the following technical scheme that.
A kind of low-cost environmental-protecting mortar, is made up of the raw material of following parts by weight：150-230 parts of 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 is milled to 45um by natural zeolite powder and tailed over to be obtained less than 12%.
The ferronickel slag sand is that the waste residue produced in smelting ferronickel alloy process is crushed to sand grains footpath and obtained less than 4.75mm
Arrive.
The water-retaining admixture is made up of lignin fibre, cellulose ether and xanthans.
It is preferred that, the cellulose ether is carboxymethyl SE-cellulose ether or ethoxyl methyl cellulose ether.
It is preferred that, the lignin fibre is to pass through the organic fiber that chemical treatment is obtained by straw.
It is furthermore preferred that the water-retaining admixture presses weight by lignin fibre, carboxymethyl SE-cellulose ether and xanthans
Amount compares 1-3:1-2:1 composition.
The slow setting early strength agent is by sodium sulphate, calcium saccharate and dimethylethanolamine by weight 1-9:1-3:1 composition.
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)2The a series of hydrated product of reaction generation, with good pozzolanic activity.Due to ferronickel slag
Formation temperature is higher, has certain hydration reaction activity under high alkali environment, there is the risk of certain alkali-aggregate reaction,
Zeolite powder has excellent suppression alkali-aggregate reaction performance, can effectively suppress the generation of alkali-aggregate reaction.In addition, zeolite powder
Construct opening big, 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 type of river sand, and the present invention replaces river using part of nickel scum sand
Sand, can play improvement plaster workability, improve the effect of mortar strength.Ferronickel slag sand is different with the water absorption rate of natural river sand,
Particle of the particle diameter less than 0.075mm contains substantial amounts of clay, organic matter etc. in river sand, and water requirement is larger, and these materials influence
The development of intensity.Broken ferronickel slag sand surface is relatively smooth, densification, and water absorption is small, can increase mortar mobility and denseness；River
The rounder and more smooth smoothness of sand profile, and ferronickel slag sand is formed by Mechanical Crushing, with certain angular structures, makes to have between aggregate
The mechanical engagement of effect, is conducive to increasing the compression strength of mortar；Sand contains the mineral such as tricalcium silicate, dicalcium silicate in ferronickel slag,
With certain hydration reaction activity, the interfacial structure of binder materials and ferronickel slag sand can be improved, adhesion strength is improved；Cellulose
Effect of the ethers additive to mortar adhesiveness and adhesion strength is the most obvious, and mortar becomes viscous after incorporation, and adhesiveness improves, and glues
Knotting strength is improved, but compression strength is substantially reduced, and cost is higher.Lignin fibre is the three dimensional network with obvious cross-linked effect
Shape structure, with preferable water imbibition, fiber reinforcement and thickening effect, can improve the workability and cracking resistance of mortar
Performance, is used in conjunction with cellulose ether, it is possible to reduce the consumption of cellulose ether, improves mortar strength.Cellulose ether and lignin
Fiber acts synergistically, and reaches water conservation, thickening, enhancing, the optimum efficiency of cracking resistance；Calcium saccharate has good delay to cement in itself
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 problem of later strength is reduced after exclusive use sodium sulphate.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, with 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, it is easy to extrude mix, and plumpness and adhesion strength are high, the adhesiveness with masonry
Can be good.
(2) present invention is a large amount of utilizes industrial solid castoff ferronickel slag, you can help, which is dissolved, handles ferronickel slag, reduces environment
Pollution, the problem of also solving the problem that natural sand shortage of resources is killed two birds with one stone.
