Description
Technical field
The present invention relates to a kind of building material and production technique thereof, be specifically related to a kind of masonry mortar, particularly relate to a kind of wet-mixing masonry mortar adopting aggregate chips to prepare.
Background technology
Generic field mixing mortar is by cement, river sand, clear water mix, plays material of construction bonding one, form the effect of firm entirety through sclerosis.Along with the raising that construction industry technical progress and civilized construction require, on-the-spot mixing mortar demonstrates its intrinsic defect day by day, as unstable in mortar quality, waste of material is large, mortar kind is single, civilized construction degree is low and contaminate environment etc.Therefore, adopt the premixing mortar of suitability for industrialized production imperative, it is the Important Action ensureing construction engineering quality, improve building operation modernization level, reduce municipal pollution.Premixing mortar refers to for the various mortar mixtures in construction project, is one of current comparatively main engineering raw material.The features such as premixing mortar has abundant raw material, cheap, production technique simple, easy construction, thus usage quantity is increasing.Meanwhile, it is high that premixing mortar has ultimate compression strength, steady quality, good endurance, the features such as convenient, environmentally-friendly sanitary of constructing, and is also main material in present building operation.
In recent years, along with growing continuously and fast of fundamental construction, the consumption of building mortar sharply increases.River sand is the necessary material ensureing mortar strength, and its consumption also sharply increases.Due to river sand resource day by day reduce, the reason such as national environmental protection is strengthened day by day, in order to protect limited river sand resource, people are finding the starting material that can substitute river sand in mortar preparation.Aggregate chips is also known as artificial sand, and surface ratio river sand is rough, has sharp corners, is less than the stone flour of 0.16mm containing more particle diameter, is the byproduct after stone processing.If aggregate chips can be adopted to substitute river sand configuration premixing mortar, then not only protect limited river sand resource, also take full advantage of aggregate chips, namely decrease environmental pollution, again reduce production cost.But, aggregate chips is replaced river sand preparation wet-mixing masonry mortar, often there is following two problems: the grain composition of (1) aggregate chips is undesirable, cause bleeding problem (mixed coarse aggregate sinks, moisture floats resembles) serious; (2) the wet-mixing masonry mortar serviceability prepared is not good enough, without mobility, and soap-free emulsion polymeization power.
Patent of invention CN103332893B discloses " a kind of Novel dry mixed plastering mortar ", composed of the following components by mass percentage: the Wingdale of 20-50%, the mine tailing of 0-30%, 20% iron tailings, the yellow ground of 15%, the cement of 9-25% and surplus admixture; Described admixture is properties-correcting agent and viscosifying agent.Described properties-correcting agent is the mixture of hydroxypropyl methyl cellulose ether, water reducer and polyvinyl alcohol, and described viscosifying agent is mortar densification powder.The mass percent of described mortar densification powder, hydroxypropyl methyl cellulose ether, water reducer and polyvinyl alcohol is mortar densification powder: hydroxypropyl methyl cellulose ether: water reducer: polyvinyl alcohol=120:1:5:3.This invention efficiently utilizes limestone tailing and iron tailings, reduces the cost of dry-mixed plastering mortar.
Summary of the invention
The present invention is directed to the problems referred to above existing for existing wet-mixing masonry mortar, provide a kind of wet-mixing masonry mortar adopting aggregate chips to prepare.The Machine-made Sand that the present invention adopts aggregate chips to replace producing by grating and river sand, overcome the dependence of premixing mortar to river sand, reduce production cost, ensure mortar quality.
Technical scheme of the present invention: the wet-mixing masonry mortar adopting aggregate chips preparation, counts by weight, is made up of following component: 18-22 part cement, 6-8 part flyash, 5-7 part breeze, 22-25 part water, 135-145 part aggregate chips, 0.5-2.0 part mortar additive; The particle diameter of described aggregate chips is for being not more than 4.75mm, and in described aggregate chips, the weight fraction of stone flour is 2-3%; The grading limit of aggregate chips is 4.75mm:10 ~ 20; 2.36mm:25 ~ 50; 1.18mm:40 ~ 50; 0.6mm:60 ~ 90; 0.3mm:80 ~ 95; 0.15mm:90 ~ 100; Fineness modulus is 3.1 ~ 4.0.Containing comparatively particle in aggregate chips, also containing powder, the intensity of this grating mixture is higher, good with the gelling material cohesiveness such as cement.
Wherein, described mortar additive is thickening agent, described thickening agent is counted by weight, is made up of following component: 2-4 part sulphonic acids air entrapment agent, 10-20 part melamine water reducer, 1-3 part caster sugar, 1-3 part hydrophober, 4-6 part Xylo-Mucine and 40-60 part sodium bentonite.Sulphonic acids air entrapment agent make to produce in mortar tiny, be uniformly distributed and the microbubble that can retain after hardening, thus improve the denseness of mortar, viscosity and water-retentivity; Melamine water reducer can reduce the water consumption of mortar, ensures mobility and the intensity of mortar; Caster sugar can extend the time of coagulation of wet-mixing masonry mortar, and Xylo-Mucine and sodium bentonite make suff water be kept at the inside of mortar, thus ensure that the development completely of the hardening and intensity of the aquation of cement, improves the bonding strength of mortar.Described thickening agent, under the synergy of each component, has good protect plasticity and water-retentivity, not only extends time of coagulation, reduces denseness loss; And improve cohesiveness and the snappiness of mortar, decrease shrinkage strain and the crack of mortar.
Wherein, described cement is 42.5 cement; 28 days intensity of described cement are 48.6Mpa.Described breeze is S95 breeze; Described breeze specific surface area is 410m
2/ kg, within 28 days, activity is 97%, and degree of mobilization is than 100%.Described flyash is second class powered coal ash; Fineness is 13.5%, needs water than 100%, and loss on ignition is 6.2%.
Adopt the compound method of the wet-mixing masonry mortar of aggregate chips preparation, comprise the following steps:
(1) count by weight, take 2-4 part sulphonic acids air entrapment agent, 10-20 part melamine water reducer, 1-3 part caster sugar, 1-3 part hydrophober, 4-6 part Xylo-Mucine and 40-60 part sodium bentonite; Thickening agent is obtained after mixing;
(2) count by weight, take 18-22 part cement, 6-8 part flyash, 5-7 part breeze, 22-25 part water, 135-145 part aggregate chips, 0.5-2.0 part mortar additive, after mixing, obtain wet-mixing masonry mortar; The particle diameter of described aggregate chips is for being not more than 4.75mm, and in described aggregate chips, the weight fraction of stone flour is 2-3%; Described mortar additive is the thickening agent that step (1) obtains.
Beneficial effect of the present invention is:
(1) the present invention adopts processing stone remaining aggregate chips replacement mechanism sand and river sand, and it is convenient and cheap that aggregate chips is drawn materials, and not only achieves the Appropriate application of resource, reduce discarded aggregate chips environmental pollution, and reduce the production cost of mortar;
(2) thickening material that the present invention adopts has dispersion mortar gel material, keeps the effect of mortar plasticity, reduce the water consumption of the masonry mortar adopting aggregate chips to produce, solve the bleeding problem that aggregate chips easily causes as raw material, ensure that its mobility and cohesive force simultaneously.
(3) the present invention is by the proportioning of reasonably optimizing mortar, while reduction mortar production cost, ensures the performance index of product, enhances the water retention of mortar, viscosity, extend time of coagulation, ensure the use continuity of mortar.
