Abstract
The invention belongs to retarder technical field, and in particular to a kind of ardealite setting retarder for cement, including phosphogypsum slag, flyash, calcareous material, wherein by mass percentage, phosphogypsum slag is 30-70%, flyash is 26-60%, calcareous material is 4-10%.The present invention can carry out stabilization, normal tune to cement and coagulate, and can also improve cement early strength, reduce cement cost, improve cement output.
Description
Technical field
The invention belongs to cement retarder technical field, and in particular to a kind of ardealite setting retarder for cement.
Background technology
Efficient retarding and water reducing agent is a kind of additive being of wide application in concrete admixture, and it is
Have slow setting concurrently and the additive of mixing water amount is greatly reduced.With capital construction development to concrete
Performance propose more and higher requirements.
High performance Water-reducing Admixtures To Cements have peptizaiton high, can preferably keep concrete it is bright fall
Degree.Penetrating into this kind of additive can make the concrete have high-performance, can obtain high-strength high-performance concrete.
The main component of existing retardation water reducing agent is generally high molecular polymer and inorganic salts.Phosphogypsum slag is wet
The industrial residue produced in method phosphoric acid production, often produces 1 ton of phosphoric acid about 4 tons of phosphogypsum slag of discharge.Phosphorus stone
The main component of cream is CaSO4·2H2O, accounts for 65-96%, and silicon compound, phosphate, other
Sulfate, additionally contains a small amount of hazardous compound such as fluoride, free acid.Such waste residue is in China's profit
With rate only 10% or so, land occupation being stacked for a long time, wasting land resource, solvable harmful substance can also be with
Precipitation enters surface water pollution environment.Therefore, developing a kind of retarder with phosphogypsum slag as raw material has
Great production practices and realistic meaning.
The content of the invention
A kind of ardealite setting retarder for cement is provided it is an object of the invention to solve above-mentioned technical problem.
The present invention is achieved in that a kind of ardealite setting retarder for cement, including phosphogypsum slag, flyash,
Calcareous material, wherein by mass percentage, phosphogypsum slag is 30-70%, flyash is 26-60%,
Calcareous material is 4-10%.
Described calcareous material can use lime.
The ardealite setting retarder for cement also includes Bentonite modifier.
The content of the modifying agent is the phosphogypsum slag, flyash and calcareous material total amount 1-2%.
The preparation method of the ardealite setting retarder for cement is to mix above-mentioned raw materials under 150-240 degree temperature
Even, insulation is cooled to room temperature after 1-2 hours.
The present invention can carry out stabilization, normal tune to cement and coagulate, and can also improve cement early strength, drop
Low cement cost, raising cement output.
