Building materials have the characteristics that good durability, high flowability, high intensity, with being mainly used for steel construction bolt and concrete foundation
Back-grouting, column and strengthening of foundation etc..As country continues to increase the promotion efficiency of building industrialization and assembled architecture,
Important materials as node connection are more applied, due to being related to reliability and the safety of monolithic architecture, property
It can require than general cement-based grouting material higher, such as《Cement-based grouting material》For general grouting material in JC/T 986
Initial flow degree require be only be not less than 260mm, 1d compression strength not less than 22MPa, 3d compression strength not less than 40MPa,
28d compression strength is not less than 70MPa, and for fabricated grouting material according to JG/T 408《Bar connecting is in the milk with sleeve
Material》It is required that be then initial flow degree be not less than 300mm, 1d compression strength not less than 35MPa, 3d compression strength not less than 60MPa,
28d compression strength is not less than 85MPa, and indices require have raising by a relatively large margin.Therefore, market there is an urgent need to develop
It is a kind of with high fluidity and high intensity with compensation contractile function, while there is lower cost, economize on resources, to environment friend
Good high-performance grouting material.
Chinese invention patent CN201410776390.1 discloses a kind of cement-based grouting material and preparation method thereof.Wherein
It is formed including two kinds, a kind of group becomes cement 350~450, gravel 300~400, middle sand 150~200, fine sand 50~100, fills out
Material 20~70, swelling agent 40~50, water-reducing agent 6~10, auxiliary agent 1~3, water 13~20；Second group become cement 350~450,
Gravel 300~400, fine sand 50~100, filler 20~50, swelling agent 40~60, water-reducing agent 8~12, helps middle sand 150~200
Agent 1~5, water 13~18.
Chinese invention patent CN201710895233.6 discloses bar connecting sleeve grouting material and preparation method thereof.Its
Middle group becomes cement 35~50, aggregate 40~50, admixture 5~20, polycarboxylate water-reducer 0.3~0.8, plastic expansion agent 0.02
~0.1, composite expanding agent 3~5, conditioning agent 0.05~0.3.
Grouting material disclosed in document above, and grouting material items main performance majority on the market is not achieved at present
The requirement of sleeve grouting material, some are then with high costs, as some products use extraordinary sulphate aluminium cement, quartz sand, steel
Fiber etc., and special cement yield is small on the market and price is high at present, natural sand resource is also environmentally protected and yield day
Benefit reduces and price increasingly increases, and also some are added to steel fibre, the fluidity being unfavorable for after initial flow degree and 30min.
