Abstract
The present invention discloses a concrete expansion agent. The concrete expansion agent comprises the following components, by weight, 45-60 parts of fluorine gypsum, 25-35 parts of fly ash, 2-12 parts of slags, 2-5 parts of alunite, 15-25 parts of a high alumina clinker, 1-3 parts of phenol and 3-6 parts of a retarding and water reducing agent. The concrete expansion agent is prepared through steps of crushing and uniform mixing. According to the present invention, the concrete expansion agent provided by the present invention has a plurality of functions of expanding, water reducing, retarding, collapse protecting, enhancing and the like; only the treatment of grinding is required in the preparation process while the treatment of calcination is not required, the production process is simple, such that a large amount of the energy can be saved, the cost is low, the economic benefit is high, the concrete expansion agent provides more market competitiveness than similar products, the environmental pollution is reduced.
Description
Technical field
What the present invention relates to is a kind of swelling agent, and what be specifically related to is a kind of concrete swelling agent, belongs to building material field.
Background technology
Cement expansive material is a kind of concrete admixture with great market capacity and development prospect.It has the temperature of reduction and coagulates native hydration heat, improves concrete strength and impervious ability, characteristics such as compensating concrete shrinking percentage.Be widely used in underwater engineering, flood control project and all kinds of large-sized concrete construction work.Concrete admixture commonly used in the market has common swelling agent, water reducer, retardant, retardation water reducing agent etc.; Though these admixtures all can improve the quality of the Yin Dynasty to some extent; But its function is unicity, thus when using these admixtures as convenient construction with improve concrete quality and need use multiple admixture to satisfy the needs of modern project simultaneously the high-performance quilt, but in actual the use because of the mutual capacitive between the admixture; Reasons such as proportioning; Cooperate trouble, and also there is adaptability problem in different admixture, fails to satisfy building bound pair high-performance enemy's demand.
And domestic existing some cement expansive material adopts pure raw material to carry out pyroprocessing to process, and cost is high, and energy consumption is big; And great majority are high-alkali cement expansive materials, and addition content is big, and are fluorine-containing; There is sizable gap in the production technique relative complex with the low alkali cement expansive material of international leading product.According to literature survey; The domestic waste residue fluorgypsum in production fluorine Lyons and the flyash of heat power plant's discharge of once utilizing is the raw material production cement expansive material; But this swelling agent is two kinds of raw materials, and simple mixing is levigate, its performance is not done further adjustment and improvement, so its addition content is big; Need 15-20%, lack economy.
Summary of the invention
The objective of the invention is to overcome the defective that prior art exists; A kind of multiple functions such as expansion, diminishing, slow setting, guarantor are collapsed, enhancing that have are provided; Easy construction, good with various cement adaptabilities, can satisfy the cement expansive material that commerical ready-mixed concrete and pump concrete are used; And cost is low, need not the false burning of high temperature.
The technical scheme that the present invention adopts is following:
A kind of cement expansive material is characterized in that: comprise the following component of meter by weight:
Fluorgypsum 45-60 part, flyash 25-35 part, slag 2-12 part, alunite 2-5 part, high alumina 15-25 part, phenol 1-3 part, retardation water reducing agent 3-6 part;
The preferred weight umber of said cement expansive material is:
50 parts of fluorgypsums, 28 parts in flyash, 6 parts in slag, 2 parts of alunites, 15 parts of high aluminas, 2 parts of phenol, 4 parts of retardation water reducing agents;
The preparation method of said cement expansive material is:
A, the fluorgypsum with above-mentioned weight part, flyash, slag, alunite, high alumina are ground into powder with kibbler, and be subsequent use;
B, the resulting powder of steps A is put into stirrer, add phenol, retardation water reducing agent stirred after 4-8 minute, made cement expansive material.
The present invention compared with prior art has the following advantages:
1, the cement expansive material processed of the present invention is a kind of multifunctional expanded dose of integrating expansion, enhancing, diminishing, slow setting, has tangible diminishing, slow setting and enhancement.In concrete, add swelling agent of the present invention, can reduce the rate of loss of slump in the construction process, and can reduce hydration heat of cement significantly.Obviously be superior to the alkali prepared at the scene with multiple single admixture with the concrete stability of its preparation and flexibility; Be specially adapted to prepare the high-performance commerical ready-mixed concrete, can be widely used in structure from waterproofing work, big volume rod coagulates soil; Large area concrete, super-long structural engineering etc.
2, cement expansive material of the present invention need not calcined, and only needs grinding, and production technique is simple, can save mass energy, and is with low cost, and economic benefit is high, compares with like product, has more the market competitiveness, simultaneously, has reduced the pollution to environment.
