The cement is Portland cement with the grade not lower than 42.5. The admixture is a mixture of silica fume, fly ash and mineral powder mixed in any proportion. The acid-resistant rubber powder is a mixture of phenylpropenoic acid, modified rubber neoprene and vinyl acetate-neoprene copolymer emulsion powder which are mixed in any proportion. The water reducing agent is a naphthalene water reducing agent or a polycarboxylic acid water reducing agent. The aggregate is machine-made sand, quartz sand or broken stone. The material not only has strong acid resistance, but also has the advantages of self-compaction, micro-expansion, high early and later strength, simple and convenient construction and the like of the cement-based reinforced grouting material.
Description
Technical field
The invention belongs to building material field, be specifically related to a kind of cement based reinforcing grouting material compounding process having resistance to strong acid performance, this reinforcing grouting material can be used as the concrete structure reinforcement under strong acid corrosive environment, also can be used as acid resisting concrete.
Background technology
The concrete structure of some petrochemical industry, chemical enterprise; the beam column, piping lane post etc. of such as treatment tank, factory building; be subject to the corrosion of the acid waste water waste gas that factory discharges; occur that concrete cover peels off very soon, inner reinforcing bar is by corrosion condition; weather resistance is very poor; need to adopt the long-pending reinforcing of enlarged cross section, conventional reinforcement material is that cement based reinforces grouting material for this reason.It is not acidproof that cement based due to routine reinforces grouting material, and the concrete structure after reinforcing still exists short defect in work-ing life.
Acid resisting concrete conventional in engineering structure is water glass class, generally with water glass and Sodium Silicofluoride for jointing compound, be equipped with powder and aggregate is made, this kind of material ultimate compression strength is low, poor fluidity, time of coagulation be short, should not be used for that concrete structure enlarged cross section is long-pending reinforces.The corrosion resistant concrete compound method that it is component that patent 201310434672.9 discloses with cement, reinforced plastic glass fibre, acidproof fibrous magnesium silicate, stone and admixture, promotes concrete acid resistance mainly through reinforced plastic glass fibre, acidproof fibrous magnesium silicate.Patent CN 102674744A discloses a kind of compounding process of Multi-functional acid-resistant concrete gel powder, what this acidproof gel powder improved inside concrete gelling system with basicity regulation and control mineral admixture consists of master, mainly improve concrete density, optimize hydrated product structure, reduce based on perviousness, reduce the intrusion speed of acidic solution, reach lifting acid-fast ability.
The acid-fast ability of inorganics is poor, and some macromolecule organics have good acid corrosion-resistant ability, adopts organics modifications inorganics, both can have more organic physicochemical properties, and retain the fundamental characteristics of inorganics simultaneously.The development of redispersable latex powder technology, reinforces grouting material for the cement based preparing resistance to strong acid performance and provides another kind of Technology Ways.
Summary of the invention
Thering is provided a kind of during technical problem to be solved by this invention has the cement based of resistance to strong acid performance to reinforce grouting material, this material not only has resistance to strong acid ability, possesses cement based simultaneously and reinforces the advantage such as self-compacting that grouting material has, microdilatancy, early stage and later strength is high, easy construction.
For solving the problems of the technologies described above, the technical solution used in the present invention is, a kind of have the cement based of resistance to strong acid performance to reinforce grouting material, and it is made up of the component of following mass fraction:
Cement: 100 parts
Adulterant: 0 ~ 50 part
Acidproof rubber powder: 20 ~ 30 parts
Water reducer: 3 ~ 10 parts
Aggregate: 200 ~ 300 parts
Swelling agent: 10 ~ 20 parts
Water-holding agent: 0 ~ 0.5 part
Described cement is be not less than the silicate cement of 42.5 grades.Described adulterant is the miscellany that silicon ash, flyash and breeze mix with arbitrary proportion.Described acidproof rubber powder is the miscellany that derived from phenyl acrylic acid, modified rubber neoprene and vinyl acetate between to for plastic-chloroprene rubber emulsion copolymer powder mixes with arbitrary proportion.Described water reducer is naphthalene water reducer or polycarboxylate water-reducer.Described aggregate is the miscellany that Machine-made Sand, quartz sand or rubble mix with arbitrary proportion.Described swelling agent is that UEA swelling agent or nitroso-group get angry swelling agent with the mixed miscellany of arbitrary proportion.Described water-holding agent is ether of cellulose, its molecular weight 20000 ~ 40000.
The main acidproof mechanism of action of the present invention is: acidproof rubber powder can form one deck continuous thin film on hydrated product surface, and this film itself has resistance to strong acid performance, and the hydrated product of hindered acid and cement reacts; The calcium hydroxide that hydrated cementitious produces can be converted into acidproof Calucium Silicate powder by adulterant, strengthens density simultaneously, reduces the perviousness of acid solution; Water reducer plays enhancing, fluid effect; Swelling agent plays the effect strengthening density.By above-mentioned effect, make material not only have the fundamental property of grouting material, possess the effect of resistance to strong acid simultaneously.
