Abstract
The present invention discloses phosphorous ground slag cement mortar, and comprises ordinary silicate cement, phosphorous ground slag, sand and water. On the one hand, the phosphorous ground slag used in the present invention is used as mixed material to substitute the cement in equal weight to be mixed into the pre-mixing commodity mortar, thus reducing the consumption volume of the cement; on the other hand, the retardation property of the phosphorous slag is used to obviously prolong the condensation time, thereby overcoming the weakness that the retardation agent must be added into the traditional pre-mixing commodity mortar, and can realize the effect similar to the adding of the retardation agent. Therefore, the present invention makes full use of the effect of the phosphorous to improve the workability of the mortar, thereby greatly reducing the production cost, and reducing the environmental pollution.
Description
Technical field
The present invention relates to a kind of construction cement mortar, is a kind of construction cement mortar that is mixed with phosphorus slag powder specifically.
Background technology
The premixing commodity mortar refers to various starting material (comprising water) are prepared and factory operation through reasonable, is transported to a kind of mortar product in building site by transportation means (using airtight tank car usually); Be characterized in that production lot is big, steady quality, comprehensive cost reduce, but for guaranteeing the normal construction activity duration, need the special mortar retardant of admixture to guarantee that mortar can store for a long time in encloses container, can guarantee that again mortar and body material bonding firmly and can sclerosis rapidly in atmosphere, because the adding of retardant, the cost of mortar just increases greatly.
Phosphorus slag is that obtain when producing yellow phosphorus with electric furnace process a kind of is the industrial residue of main component with the Calucium Silicate powder, and what obtain after cold quenching is handled is the granulation electric furnace phosphoric slag.Because China's phosphate rock resource is abundant, according to statistics, the phosphorus production ability of China in 2002 has reached 98.49 ten thousand tons, and actual production reaches 69.39 ten thousand tons, become first in the world phosphorus production and export State, the 2005 phosphorus production abilities of being only river, Yunnan-Guizhou E4Sheng just are 850,000 ~ 900,000 tons.Therefore pile up like a mountain for the phosphorus slag of discharging, and the problem of environmental pollution that brings is on the rise.Although China was studied with regard to the comprehensive utilization to phosphorus slag since the seventies in last century, mainly contain and utilize the yellow phosphorus slag to prepare cement, devitrified glass, concrete etc.But because phosphorus slag slow setting, slow strong effect are remarkable, so its utilization is still limited so far, therefore effectively utilize the phosphorus slag resource on a large scale, reduce environmental pollution, giving full play to the effect of phosphorus slag and the consumption of minimizing retardant and cement and reduce the mortar production cost, is to need the further problem of solution.
Summary of the invention
Technical problem to be solved by this invention is, a kind of phosphorus slag powder sand-cement slurry is provided, and it belongs to the premixing commodity mortar, utilizes the P that exists in the phosphorus slag
2O
5And F
-Delay the characteristic of hydrated cementitious, its big volume is applied in the premixing commodity mortar, and under the situation of not mixing retardant, not only effectively prolonged mortar time of coagulation, improve the mortar workability, reach the effect close with the admixture retardant, simultaneously under the prerequisite that intensity and other technical feature meet the demands, reduce cement consumption and production cost significantly, reduced environmental pollution, realized the greenization that the premixing commodity mortar is produced.
In order to address the above problem, the present invention has adopted following technical scheme:
A kind of phosphorus slag powder sand-cement slurry of not mixing retardant is provided, and the prescription of this mortar very is by weight:
In the gelling material: cement accounts for 20～50%, and phosphorus slag powder accounts for 50～80%;
The exciting agent of admixture accounts for 1.5～8% of gelling material in addition; Water reducer accounts for 0.2～0.3% of gelling material;
Sand: by cement-sand ratio 1:2～1:6 amount of getting;
Water: be controlled at 30～110mm with denseness and be advisable.
The fineness of phosphorus slag powder is greater than 410m
2/ kg.
The cement that adopts in the prescription is ordinary Portland cement or Portland blast.
The cement intensity grade that adopts in the prescription is 32.5 or 42.5.
Above-mentioned exciting agent is alkali metal sulfates or gypsum; Or the composition of said two devices.
Above-mentioned exciting agent is the composition of alkali metal sulfates and gypsum, and wherein the weight percent of alkali metal sulfates is 0.5～2%, and the weight percent of gypsum is 1%～6%.
Gypsum is desulfurated plaster, fluorgypsum, phosphogypsum or the plaster of paris.
Water reducer is sulfonated lignin.
Sand in the prescription is medium sand, and particle diameter is less than 5mm, and water ratio is less than 0.5%.
Compared with prior art, the present invention replaces cement quality with phosphorus slag powder as the big volume equivalent of mixing material and mixes the premixing commodity mortar, reduced cement consumption, and utilize the slow setting characteristic of phosphorus slag, significant prolongation time of coagulation, solved the shortcoming of essential admixture retardant in traditional premixing commodity mortar, given full play to the effect of phosphorus slag, simultaneously, use industrial waste gypsum and utilized the sulfonated lignin water reducer, and the sulfonated lignin water reducer is to extract xylogen after sulfonation in a kind of waste liquid that utilizes pulp production, the Industrial products that condensation forms, itself be exactly to reclaim fully again, sharp useless, reduce water pollution and energy-saving and cost-reducing green ecological product, has certain delayed coagulation, and it is better with the consistency of other admixture, so the present invention has made full use of industrial solid castoff, greatly reduces production cost, has reduced environmental pollution.
The present invention utilizes P in the phosphorus slag
2O
5And F
-Slow setting characteristic to hydrated cementitious, regulate the material volume, the mortar strength that records and other technical indicator all satisfy " commodity mortar production and utilisation technology rules " (DG/TJ08-502-2006) standard-required, the mortar that the present invention prepares when the phosphorus slag powder volume be lower than gelling material 80% the time strength grade can reach M20; The phosphorus slag powder volume is lower than 40% o'clock of gelling material, and strength grade can reach M30; Can be used for building by laying bricks or stones, plaster and ground surface works of general industry and civil building and structures, not only turn waste into wealth, turn harm into good, and alleviate environmental pollution, save a large amount of soils, have remarkable Technological Economy meaning.
