Abstract

The invention discloses fly ash dry-mixed mortar, belonging to the field of the ready mixed and dry-mixed mortar material for building. The dry-mixed mortar is prepared by mixing the following ingredients in parts by weight: 25-30 parts of fly ash, 0-5 parts of cement, 65-75 parts of aggregate, 0.15-0.3 part of composite exciting agent, 0.03-0.05 part of water retention agent and 0.3-0.5 part of anti-cracking agent. Compared with the prior art, the fly ash dry-mixed mortar of the invention directly uses fly ash as cementing material and is characterized by energy saving, environmental protection, low material cost and the like.

Description

The flyash dry-mixed mortar
Technical field
The present invention relates to a kind of premixing dry-mixed mortar material for building, specifically a kind of flyash dry-mixed mortar.
Background technology
Along with the development of society, people improve constantly the requirement of construction quality, environmental requirement and civilized construction, and the advantage that is dry mixed mortar obtains more and more people's favor.
In the prior art, the main gelling material of dry-mixed mortar is cement or gypsum, and the consumption of cement mostly is not less than about 15%, and the consumption of gypsum also is not less than 30%.Although flyash also can be used as supplementary cementitious material or filler uses, consumption can not surpass 10%, otherwise the problems such as mortar cracking, hollowing very easily occur.
On the other hand, China is one of a few country take coal as main energy sources in the world, and coal accounts in Energy Mix more than 75%, the coal-fired topsoil that causes, water pollutes, and a large amount of generations of flyash all seriously threatening ecotope.At present, flyash at building materials, build the worker, build the road, the comprehensive utilization work of the aspect such as backfill, agricultural is fully under way, even so, the comprehensive utilization ratio of flyash also can only reach about 65%, still have every year more than 200,000,000 ton flyash to store up, occupy cultivated land, pollute.
Summary of the invention
Technical assignment of the present invention is for above-mentioned the deficiencies in the prior art, and a kind of energy-conserving and environment-protective are provided, the flyash dry-mixed mortar that the cost of material is low.
Technical assignment of the present invention is realized in the following manner: the flyash dry-mixed mortar is mixed by the batching of following weight proportion:
Flyash 25-30 part
Cement 0-5 part
Aggregate 65-75 part
Exciting agent 0.15-0.3 part
Water-holding agent 0.03-0.05 part
Anti-fissuring agent 0.3-0.5 part,
Described compound activator is by AL 2(SO 4) 3, KAL (SO 4) 212H 2O, Na 2SO 3, trolamine is with 2.5: 2: 1: 1 weight proportion is composite to be obtained.
In order to make it can better be applicable to exterior wall, flyash dry-mixed mortar of the present invention can also be mixed by the batching of following weight proportion:
Flyash 25-30 part
Cement 0-5 part
Aggregate 65-75 part
Exciting agent 0.15-0.3 part
Water-holding agent 0.03-0.05 part
Anti-fissuring agent 0.3-0.5 part
Hydrophobizing agent 0.1-1 part,
Described compound activator is by AL 2(SO 4) 3, KAL (SO 4) 212H 2O, Na 2SO 3, trolamine is with 2.5: 2: 1: 1 weight proportion is composite to be obtained.
Further,
Described hydrophobizing agent is polymkeric substance redispersible powder, sodium stearate or Zinic stearas.
The fineness of described flyash is preferably 300~500 orders.
Described aggregate is the mixture of one or more materials in the pulverized particles of Machine-made Sand, river sand, water-granulated slag or building waste, and the fineness of aggregate is less than 4 millimeters.
Described water-holding agent can be water-holding agent general in the prior art, such as polyvinyl alcohol, polyoxygenated alkanes etc., preferably use the mixture of one or more materials in methylcellulose gum, Vltra tears, hydroxyethylmethyl-cellulose or the treated starch (as: organic phosphate starch, cationic starch, anionic starch, vinyl cyanide starch etc.).
Described anti-fissuring agent can be anti-fissuring agent general in the prior art, preferably uses xylon, polyacrylonitrile fibre, fibrous magnesium silicate, steel fiber, glass fibre or aluminium powder.
Above-mentioned flyash preferably uses I and II flyash; Cement preference uses the above cement of 425#.
The present invention is by adding water-holding agent and compound activator etc., with appropriate proportioning, this low activity activity of materials of flyash is improved, the condition of namely utilizing the reduction flyash such as water-holding agent and exciting agent to react makes material (flyash or flyash and cement) form final mortar product by hydration reaction.
In the present invention, cement plays the effect of further increase mortar strength, in most cases needn't add.When needing the motar of higher-strength, can add a small amount of cement.
Flyash dry-mixed mortar of the present invention compared with prior art has following outstanding beneficial effect:
(1) need not or with a small amount of cement, directly take flyash as gelling material, overcome in the prior art and can only do the deficiency that supplementary cementitious material or filler are produced dry-mixed mortar with flyash, the all technical of product meets the indices requirement in the national sector standard fully, energy-conservation, reduction of discharging, cost are low, for utilization of fly ash has increased a new way;
(2) consumption of flyash can reach more than 30% in the product, has solved the shortcoming of mortar cracking, hollowing when the flyash consumption is excessive in the existing dry-mixed mortar;
(3) all raw materials are environment-friendly materials, really accomplish nontoxicly, adapt to people to the requirement of environmental protection;
(4) various raw materials are commercially available common product, are easy to realize, cost is low.
