Abstract
The no-shrinkage self-densifying material for reinforcing building structure consists of Portland cement 30-40 wt%, expansion agent 1-4 wt%, inorganic non-metal ore powder 3-6 wt%, water reducing agent 0.2-0.6 wt%, sand for building 50-65 wt%, and cellulose ether 0.002-0.02 wt%. It is prepared through weighing the materials, mixing in a mixer for over 5 min, and packing. It has the features of high flowability, no shrinkage, high strength, etc.
Description
Technical field
The present invention relates to a kind of building structure reinforcement material that does not have contraction, self-compacting, can be used for various building structure reinforcements, sectional dimension is amplified and is repaired, and belongs to inorganic cement mortar material technical field.
Background technology
Domestic present building structure reinforcement, cross section up-sizing are mainly taked deposit concrete or with the method for common grouting material.
The shortcoming of deposit concrete mainly is: most applications is subjected to place restriction and can't the commodity in use concrete; A lot of situation cross sections up-sizing is less, and the bar spacing between template and the former concrete surface is less, and the scene do not possess the condition of vibrating, and normal concrete can't be poured into a mould closely knit.
The performance of common on the market grouting material is primarily aimed at Equipment Foundations grouting and decides, and is mobile big, mixes and stirs the slurry instability, easily segregation; Aggregate size is less than normal, and cement consumption is bigger than normal, and is easy to crack; And surface porosity is more.
Summary of the invention
The objective of the invention is to invent a kind of building structure reinforcement material that does not have contraction, self-compacting.
For realizing above purpose, technical scheme of the present invention provides a kind of building structure reinforcement material that does not have contraction, self-compacting, it is characterized in that, form: ordinary Portland cement 30-40, swelling agent 1-4, inorganic non-metallic breeze 3-6, water reducer 0.2-0.6, common building sand 50-65, ether of cellulose 0.002-0.02 by following weight percent raw material.
Described ordinary Portland cement need meet the GB175-85 standard; The CSA that described swelling agent selects for use Tangshan polar bear special cement company limited to produce; Described inorganic non-metallic breeze is commercially available silicon powder Si02 content 〉=92%; The SN-II that described water reducer selects for use auxiliary reagent factory, the May 4th farm, Shanghai to produce; Described ether of cellulose is a methylhydroxypropylcellulose ether, and viscosity is 300-600maps/20 ℃ (2%).
A kind of preparation method who does not have the building structure reinforcement material of contraction, self-compacting, its method is:
Step 1. takes by weighing each raw material by weight percentage;
Each raw material that step 2. will take by weighing is placed on to mix in the forced action type mixing machine and gets final product more than 5 minutes, is packaged into bag then, just can transport the construction site to through being up to the standards.
Wherein ordinary Portland cement, swelling agent and inorganic non-metallic breeze are gelling material.
The present invention is agglutination material with cement, adopt sulplo-aluminate, calcium oxide expansion agents, it is non-bleed type, make the reinforced material volume stability, reduce shrinkage cracking, adopt high efficiency water reducing agent, inorganic non-metallic breeze and low viscosity methylhydroxypropylcellulose ether to adjust the viscosity of reinforced material mixture, make reinforced material have flowability and water-retentivity, satisfy anti-bleeding, the education resistance energy of reinforced material, guarantee the homogeneity and the density of reinforced material, mix commodity mortar through factory's batching, mixing, doing of packing.The scene can be used after adding the water stirring, has and does not have contraction, self-compacting, and promptly mobile, easy working characteristic are applicable to that various building structure reinforcements or sectional dimension are amplified and repairing.
Advantage of the present invention is:
1. have large fluidity, do not have to shrink, early strong characteristic;
2. high efficiency water reducing agent, inorganic non-metallic breeze and low viscosity methylhydroxypropylcellulose ether is used, can adjust the viscosity of reinforced material mixture, when guaranteeing reinforced material mixture large fluidity, reduce the possibility that the reinforced material mixture produces segregation, bleeding;
3. adopt sulplo-aluminate, calcium oxide composite expanding agent, make and build the body volume stability;
4. factory is specialized produces, and various material prescription technology are concentrated realization, constant product quality, the supply of material of commodity bagging, transportation, storage, easy to use.
