The special early strength agent used in above example is TT-1, and early strength agent is formulated with nanoreinforcement material, nanometer
Reinforcing material composition can quickly absorb the free water generation crystallization water and hydrated cementitious complexing, can improve grouting material system rapidly
One day intensity can make grouting material system intensity reach 80Mpa for three days, and provide the swelliong power of system, therefore system ungauged regions,
Later strength sustained, stable growth, no retraction phenomenon.It, will not there is no being had an impact to fluidity while improving early strong
There is the phenomenon that loss is excessive.
Maximum aggregate size is no more than 25mm.
The general silicon 52.5 of cement selection
Sand during aggregate preferably uses is not preferably less than 15% by the granule content of 0.315mm sieve pores, and no more than 30%, leads to
The granule content for crossing 0.160mm sieve pores is not preferably less than 5%.
It is aided with suitable water-reducing agent, water-reducing rate more than 30%.
And the nanoreinforcement material composition in the above embodiments can quickly absorb the free water generation crystallization water and cement
Aquation is complexed, and can improve one day intensity of grouting material system rapidly, grouting material system intensity can be made within three days to reach 80Mpa, expands
The swelliong power of agent offer system, therefore system ungauged regions, later strength sustained, stable growth, no retraction phenomenon.It is early strong improving
While, early strength agent is not in the phenomenon that loss is excessive there is no being had an impact to fluidity.
Comparative example
Select existing sleeve grouting material, including cement 50, quartz sand 50, gypsum 5, common swelling agent 13, additive 5,
Fiber 5, no nanoreinforcement material.
Sleeve slurry obtained obtains following characteristic：
Because assembled architecture steel connector socket wrench specially adapted for it grouting material is under different construction conditions, the temperature difference is larger, herein water
Material is than us according between weather temperature 13%-17%.
Cross that low viscosity is excessive, and fluidity is too small is not easy to construct with water, with dilutional hyponatremia it will cause 28 days later stages intensity and
Shrink increase.
And in comparative example, strength of cement is substantially weaker, and anti-freezing property is also poor.
Above-described is only the preferred embodiment of the present invention, it is noted that for those of ordinary skill in the art
For, without departing from the concept of the premise of the invention, various modifications and improvements can be made, these belong to the present invention
Protection domain.
