Description
Technical field
The present invention relates to a kind of building material and production technology thereof, be specifically related to a kind of masonry mortar, relate in particular to a kind of wet-mixing masonry mortar that adopts aggregate chips preparation.
Background technology
Common on-the-spot mixing mortar is by cement, river sand, clear water mix, plays the construction material one that bonds through sclerosis, forms the effect of firm entirety. Along with the raising that building industry technological 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 large, mortar kind is single, civilized construction degree is low and contaminated environment etc. Therefore, adopt the premixing mortar of suitability for industrialized production imperative, it is the Important Action that ensures construction engineering quality, raising construction modernization level, reduces municipal pollution. Premixing mortar refers to the various mortar mixtures for construction project, is one of current comparatively main engineering raw material. The features such as premixing mortar has abundant raw material, cheap, production technology simple, easy construction, thereby use amount is increasing. Meanwhile, it is high that premixing mortar has compression strength, steady quality, good endurance, and the features such as convenient, environmentally-friendly sanitary of constructing are also main materials in present construction.
In recent years, along with growing continuously and fast of capital construction, the consumption of building mortar sharply increased. River sand is the necessary material that ensures mortar strength, and its consumption also sharply increases. Due to reasons such as river sand resource reduce day by day, national environmental protection is strengthened day by day, in order to protect limited river sand resource, people are finding the raw material that can substitute river sand in mortar preparation. Aggregate chips claims again artificial sand, and surface ratio river sand is rough, has sharp corners, contains the stone flour that more particle diameter is less than 0.16mm, is the byproduct after stone processing. If can adopt aggregate chips to substitute river sand configuration premixing mortar, not only protect limited river sand resource, also take full advantage of aggregate chips, reduce environmental pollution, reduce again production cost. But, aggregate chips is replaced to river sand preparation wet-mixing masonry mortar, often there are following two problems: the grain composition of (1) aggregate chips is undesirable, cause bleeding problem (mixed coarse aggregate sinking, moisture floating resemble) serious; (2) the wet-mixing masonry mortar service behaviour of preparation is not good enough, without mobility, without cohesive force.
Patent of invention CN103332893B discloses " a kind of Novel dry mixed plastering mortar ", composed of the following components by mass percentage: the lime stone of 20-50%, the mine tailing of 0-30%, 20% iron tailings, 15% yellow ground, the cement of 9-25% and the additive of surplus; Described additive is modifier and thickening agent. Described modifier is the mixture of hydroxypropyl methyl cellulose ether, water reducer and polyvinyl alcohol, and described thickening 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 has effectively utilized limestone tailing and iron tailings, has reduced the cost of dry-mixed plastering mortar.
Summary of the invention
The present invention is directed to the existing the problems referred to above of existing wet-mixing masonry mortar, a kind of wet-mixing masonry mortar that adopts aggregate chips preparation is provided. The present invention adopts aggregate chips to replace Machine-made Sand and the river sand produced by grating, has overcome the dependence of premixing mortar to river sand, reduces production costs, and ensures mortar quality.
Technical scheme of the present invention: adopt the wet-mixing masonry mortar of aggregate chips preparation, meter, 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 by weight; 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; Modulus of fineness is 3.1～4.0. In aggregate chips, contain compared with particle, also contain powder, the intensity of this grating mixture is higher, good with Binder Materials caking property 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 entraining agent, 10-20 part melamine water reducing agent, 1-3 part soft white sugar, 1-3 part hydrophober, 4-6 part sodium carboxymethylcellulose and 40-60 part sodium bentonite. That sulphonic acids air entraining agent makes to produce in mortar is tiny, be uniformly distributed and harden after the microbubble that can retain, thereby improve denseness, viscosity and the water-retaining property of mortar; Melamine water reducing agent can reduce the water consumption of mortar, ensures mobility and the intensity of mortar; Soft white sugar can extend the setting time of wet-mixing masonry mortar, and sodium carboxymethylcellulose and sodium bentonite make enough moisture be kept at the inside of mortar, thereby has ensured the aquation hardening of cement and the development completely of intensity, has improved the adhesive strength of mortar. Described thickening agent, under the synergy of each component, has good protect plasticity and water-retaining property, has not only extended setting time, has reduced denseness loss; And cohesiveness and the pliability of mortar, contraction distortion and the crack of having reduced mortar are improved.
Wherein, described cement is 42.5 cement; 28 days intensity of described cement are 48.6Mpa. Described breeze is S95 breeze; Described breeze specific area is 410m2/ kg, within 28 days, activity is 97%, fluidity 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%.
The compound method that adopts the wet-mixing masonry mortar of aggregate chips preparation, comprises the following steps:
(1) count by weight, take 2-4 part sulphonic acids air entraining agent, 10-20 part melamine water reducing agent, 1-3 part soft white sugar, 1-3 part hydrophober, 4-6 part sodium carboxymethylcellulose and 40-60 part sodium bentonite; After mixing, obtain thickening agent;
(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 aggregate chips is drawn materials convenient and cheap, has not only realized the reasonable utilization of resource, reduces discarded aggregate chips environmental pollution, and has reduced the production cost of mortar;
(2) thickener that the present invention adopts has the effect that disperses mortar gel material, keeps mortar plasticity, reduce the water consumption of the masonry mortar that adopts aggregate chips production, solve the bleeding problem that aggregate chips easily causes as raw material, ensured its mobility and cohesive force simultaneously.
(3) the present invention, by the match ratio of reasonably optimizing mortar, in reducing mortar production cost, ensures the performance indications of product, has strengthened water retention, the viscosity of mortar, extends setting time, ensures the use continuity of mortar.
