Description
Technical field
The invention belongs to grouting material technical field, and in particular to a kind of duct grouting material and preparation method thereof.
Background technology
Need to carry out inside concrete reserving hole channel grouting in engineer applied and former concrete forms overall closely knit knot
Structure, existing grouting material, mainly cement-based mortar composition, when carrying out grouting construction, composition and the water of grouting material cement mix
Close and hydration reaction occurs, generate hard hydrate, sand therein is cemented together filling, and forms the higher knot of compression strength
Structure body, but the grouting material poor fluidity, difficulty of construction is big, pipeline leakiness after construction, and exists after the grouting material aquation
Volume contraction, gap be present with original pipeline after hardening, the grouting material does not possess osmotic effect also, it is impossible to penetrate into former concrete
In duct wall, preventing grouting structure and former xoncrete structure, easy fracture, easily carbonization, it makes from forming an overall compact structure
It is poor with effect, therefore prior art needs further improve.
The content of the invention
It is an object of the invention to provide a kind of self-compaction, microdilatancy, Thief zone duct grouting material.
Based on above-mentioned purpose, the present invention adopts the following technical scheme that：
A kind of duct grouting material, is made up of following parts by weight：P. II 52.5R cement 20-30 parts, alumina cement 8-12 parts, UEA
Swelling agent 4-6 parts, quartz sand 40-60 parts, polycarboxylate water-reducer 0.0005-0.001 parts, re-dispersible glue powder 1-3 parts, glucose
Sour sodium 0.0002-0.0003 parts, cellulose ether 0.0005-0.001 parts, anhydrite 4-6 parts, Na2O·nSiO2 0.0012-
0.0018 part, solid defoaming agent 0.001-0.002 parts, water 10-12 parts.
Further, the solid defoaming agent is polysiloxanes.
Further, the preparation method of described a kind of duct grouting material, is comprised the steps of：By the 52.5R water of P. II
It is mud, alumina cement, UEA swelling agents, quartz sand, polycarboxylate water-reducer, re-dispersible glue powder, sodium gluconate, cellulose ether, hard
Gypsum, Na2O·nSiO2, solid defoaming agent it is well mixed after, add water and remix uniformly.
The water consumption of grouting material can be greatly lowered in the present invention, improve the mobility of grouting material, make grouting material by gravity
Or grouting pressure is voluntarily closely knit, unnecessary water can be prevented to be internally formed defective voids in Behavior of Hardened Cement Paste, overall density is good, and fills
The early stage of slurry and later stage compression strength are high, and volume contraction will not occur in hydration process, and permeance property is good, and homogenieity is good,
Security is good, corrosion-resistant, service life length.
