Cement-based high strength grouting material for cement test analysis

High strength grouting cement base high strength grouting material equipment foundation with high strength grouting cement base high strength grouting material is made of cement as the basic material, the amount of fine aggregate and attend a few concrete and beautiful seam an agent, and other data of dry mixing materials, after mixing with large activity of water, high early strength xianning bearing high strength grouting material performance of the micro bulk up. Because of its no shortening high strength self-compacting nanning high strength grouting material manufacturer construction is convenient wait for a characteristic, is widely applied in the equipment foundation in secondary grouting anchor bolt anchorage concrete repair reinforcement, etc. Because imported high strength grouting material of high strength grouting material is expensive, site experiment combined with the domestic demand in recent years, the discussion was active for high strength grouting material in China and has achieved great development. In performance and cost of materials is a breakthrough, cement base of domestic high strength cement is often used in Portland cement grout. And after increase swell the seam an agent to promote internal ettringite formation, cement paste for early strength Gao Qiangwei swell, such as performance, will happen because of ettringite in 0 ℃ or breakdown reports have worried about swelling in the domestic market the stability of the seam an agent performance. High strength grouting material questioned the stability of the system on the engineering application, sulphur aluminate cement with a rapid hardening characteristics of the early strength slightly swelling, available manufacturing cement base high strength grouting material. But its price is general Portland cement is high, many and have a discussion with silicate cement sulfate aluminate cement composite gel system to reduce the cost.
