Abstract
The no-shrinkage grout material consists of Portland cement 35-50 wt%, expansion agent 1-6 wt%, water reducing agent 0.1-0.8 wt%, sand for building 45-60 wt%, and cellulose ether 0.001-0.08 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 contraction-free grouting concrete, be applied to the foundation grouting of various device installation, Steel Structure Installation.Belong to inorganic cement mortar material technical field.
Background technology
Mainly there is poor water retention property in the tradition contraction-free grouting concrete, and flowability is easily lost, and easily produces segregation, bleeding problem, actual engineering shows as that to build the body material homogeneity poor, it is easy to crack to build body, builds body and equipment bay disengagement because of material contracts makes, and not reaching does not have the purpose of shrinking grouting.
Summary of the invention
The purpose of this invention is to provide a kind of large fluidity, high-moisture-retention, anti-bleeding, anti-isolating contraction-free grouting concrete.
For realizing above purpose, technical scheme of the present invention provides a kind of contraction-free grouting concrete, it is characterized in that, form: ordinary Portland cement 35-50, swelling agent 1-6, water reducer 0.1-0.8, common building medium sand 45-60, ether of cellulose 0.001-0.08 by following weight percent raw material.
Described ordinary Portland cement must meet the GB175-85 standard; The CSA swelling agent that described swelling agent selects for use Tangshan polar bear special cement company limited to produce; FDN or 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 of contraction-free grouting concrete 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.
Ordinary Portland cement and swelling agent are formed gelling material.
Advantage of the present invention is:
The present invention have large fluidity, do not have to shrink, high-strength, early strong characteristic;
2. being used of high efficiency water reducing agent and low viscosity methylhydroxypropylcellulose ether can be adjusted the viscosity that mixture is expected in grouting, when guaranteeing grouting material mixture large fluidity, reduces the possibility that the material mixture that is in the milk produces segregation, bleeding;
3. adopt commercially available CSA swelling 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.
