Abstract
The invention discloses slag micro-powder dry mixed mortar, and belongs to the field of premixed dry mixed mortar materials. The dry mixed mortar is prepared from the following materials in part by weight: 20 to 30 parts of slag micro-powder, 5 to 10 parts of fly ash, 60 to 75 parts of aggregate, 0.3 to 0.5 part of composite exciting agent, 0.01 to 0.03 part of water holding agent, and 0.3 to 0.5 part of anti-cracking agent. Compared with the prior art, because the slag micro-powder is directly prepared into the dry powder mortar, the slag micro-powder dry mixed mortar has the characteristics of energy conservation, environmental friendliness, low material cost and the like.
Description
Technical field
The present invention relates to a kind of premixing dry-mixed mortar material for building, specifically a kind of slag micro-powder 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 prior art, the main gelling material of mortar is cement or gypsum, and the consumption of cement mostly is not less than 15% left and right, and the consumption of gypsum also is not less than 30%.Although slag micropowder also can be used on a small quantity, can only make cement together with cement clinker, flyash etc. and could use.
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 slag micro-powder dry mixed mortar that the cost of material is low.
Technical assignment of the present invention is realized in the following manner: slag micro-powder dry mixed mortar is mixed by the batching of following weight proportion:

Compound activator 0.3-0.5 part
Water-holding agent 0.01-0.03 part
Anti-fissuring agent 0.3-0.5 part.
In order to make it can better be applicable to exterior wall, slag micro-powder dry mixed mortar of the present invention can also be mixed by the batching of following weight proportion:
Slag micropowder 20-30 part
Flyash 5-10 part
Aggregate 60-75 part
Compound activator 0.3-0.5 part
Water-holding agent 0.01-0.03 part
Anti-fissuring agent 0.3-0.5 part.
Hydrophobizing agent 0.1-1 part.
Described hydrophobizing agent is polymkeric substance redispersible powder, sodium stearate or Zinic stearas.
The specific surface area of described slag micropowder is greater than 400m
2/ Kg.
Described flyash is the above flyash of one-level.
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 compound activator is that weight ratio is that the water glass of 1: 1 and Sulfothiorine mixture or weight ratio are water glass and the calcium oxide mixture of 1: 1.
Described water-holding agent can be water-holding agent general in prior art, as polyvinyl alcohol, polyoxygenated alkanes etc., preferably use the mixture of one or more materials in methylcellulose gum, Vltra tears, hydroxyethylmethyl-cellulose or 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 prior art, as fibrous magnesium silicate, steel fiber, glass fibre etc., preferably uses xylon or polyacrylonitrile fibre.
The present invention is by adding exciting agent, water-holding agent and anti-fissuring agent etc., slag micropowder, this low activity activity of materials of flyash are improved, the condition of namely utilizing the reduction slag micropowders such as exciting agent, water-holding agent and anti-fissuring agent to react makes material (slag micropowder and flyash) form final mortar product by hydration reaction.
Slag micro-powder dry mixed mortar of the present invention compared with prior art has following outstanding beneficial effect:
(1) without cement or gypsum, directly take slag micropowder as gelling material, overcome in the prior art and slag micropowder must be made into the deficiency that cement is produced dry-mixed mortar again, the all technical of product meets the indices requirement in national sector standard fully, energy-conservation, reduction of discharging, cost are low, for the utilization of slag micropowder and flyash has increased a new way;
(2) all raw materials are environment-friendly materials, really accomplish nontoxicly, adapt to people to the requirement of environmental protection;
(3) various raw materials are commercially available common product, are easy to realize, cost is low.
