Abstract
The invention discloses a high-strength shrinkage-free sleeve grouting material for rebar connection and a preparing method of the high-strength shrinkage-free sleeve grouting material. The grouting material comprises the following components in parts by weight: 300-650 parts of cement, 300-500 parts of quartz sand, 50-100 parts of pulverized slag powder, 20-40 parts of compound expanding agent, 3-12 parts of polycarboxylate superplasticizer and 0.5-12 parts of defoaming agent. The newly-stirred slurry of the high-strength shrinkage-free sleeve grouting material is in a high flow regime, the initial fluidity is 340mm or more, and the 30min fluidity is 260mm or more. The high-strength shrinkage-free sleeve grouting material is not prone to sedimentation and bleeding, even if the water using amount is large. The high-strength shrinkage-free sleeve grouting material achieves compound expanding compensation, the plastic expanding agent can well compensate early shrinkage, and the plastic expanding agent can well compensate shrinkage generated by slurry hardening in middle and later periods. The high-strength shrinkage-free sleeve grouting material is high in strength, the strength is larger than or equal to 35MPa after one day, is larger than or equal to 60MPa after 3 day, and is larger than or equal to 85MPa after 28 day. Furthermore, the high-strength shrinkage-free sleeve grouting material is environmental-friendly.
Description
Technical field
The present invention relates to a kind of high strength and no shrinting bar connecting sleeve grouting material and preparation method thereof.
Background technology
At present, this high strength and no shrinting bar connecting sleeve grouting material is exclusively used in industrialization assembled-type house
The connection of building prefabricated components is it can also be used to the back-grouting of large equipment base, the filling of steel construction suspension column
Slurry.Similar imported product price is high, on market like product generally exist fresh paste poor fluidity,
Water consumption bandwidth is less than normal, intensity is not enough, without problems such as early-age plastic expansions.
Summary of the invention
In order to solve existing like product exist fresh paste poor fluidity, water consumption bandwidth less than normal, strong
Degree is not enough, without problems such as early-age plastic expansions, it is an object of the invention to provide one high strength and no shrinting reinforcing bar
Sleeve for connection grouting material and preparation method thereof.
The purpose of the present invention is achieved through the following technical solutions: a kind of high strength and no shrinting bar connecting set
Cylinder grouting material, pulp components weight composition is as follows: cement 300～650 parts, quartz sand 300～500 parts,
Pulverized slag powder 50-100 part, composite expanding agent 20～40 parts, polycarboxylate water-reducer 3～12 parts,
Defoamer 0.5～12 parts.
Preferably, described defoamer is organic silicon defoamer.
The preparation method of a kind of high strength and no shrinting bar connecting sleeve grouting material, comprises the steps:
1), by the cement of constant weight, quartz sand importing equipment import respective pre-homogenizing storehouse carry out pre-all
Change；
2), each component carries out continuous batching in proportion；
3), compound mixed at high speed 5-7 minute in forced stirrer of preparing, then middling speed mixing 2-3
Minute, obtain dry mash；
4) dry mash, mixed imports finished product homogenizing storehouse；
5), electronic measurement is packed automatically；
6), finished product warehouse-in.
The medicine have the advantages that 1, polycarboxylate water-reducer and cement-based material have good adaptability, really
Protect fresh paste upper flow regime, and have longer operable time.
2, the deleterious bubbles that the interpolation of organic silicon defoamer introduces when can effectively eliminate slurry stirring.
3, plastic expansion agent can compensate well for early-age shrinkage, and middle and late stage extender can make up slurry well
The contraction produced after hardening.
4, the quartz sand optimizing particle size range makes slurry can obtain preferable mobility, can obtain again higher
Intensity.
5, the interpolation of pulverized slag powder, improves hydration and hardening microenvironment and the pore size distribution$ of placing body,
Long-term strength and durability to placing body have huge improvement.
Specific implementation method
The present invention is described further in conjunction with the embodiments.
