Abstract
The invention relates to a pore-like grouting agent for a road and a preparation method of the pore-like grouting agent. The pore-like grouting agent comprises 2-3 percent of water reducing agent, 0.3-0.5 percent of micro expansion powder, 0.3-0.5 percent of anti-settling agent and 96-98 percent of mineral additive. The preparation method comprises the following steps: weighing the water reducing agent, micro expansion powder, anti-settling agent and mineral additive according to a ratio, adding the mixture into a mixing stirrer and stirring, thus obtaining the pore-like grouting agent. According to the pore-like grouting agent prepared by the method, bleeding can be avoided, and the slurry is dilute, does not settle to the bottom, expands slightly and is easy for construction, and the construction quality is guaranteed.
Description
Technical field
The present invention relates to a kind of cement additive, be specifically related to a kind of hole path pressure grouting agent for highway and preparation method thereof.
Background technology
Grouting agent is mud jacking material for the girder pre-stressed pipeline pack of posttension, prevent prestressing steel anticorrosion, guarantee effectively stress transmission between prestressing tendon and concrete structure, make in duct slurry full closely knit, slurry keeps certain pH value scope, wrap up prestressing steel completely, after slurry sclerosis, have higher intensity and Young's modulus and expansion shrinkage-void and bonding force.At present, on market, most grouting agent has bleeding, thickness, shrinks and grabs the deficiencies such as the end, for the use of grouting agent is made troubles.
Summary of the invention
The object of this invention is to provide a kind of hole path pressure grouting agent for highway and preparation method thereof, the grouting agent of preparing by the method can prevent bleeding, and its slurry rare, do not grab the end, microdilatancy, be easy to construction and ensure construction quality etc.
The object of the invention is to be achieved through the following technical solutions:
For a hole path pressure grouting agent for highway, described grouting agent composition and mass fraction thereof comprise:
Water reducer 2-3 part
Microdilatancy powder 0.3-0.5 part
Anti-sedimentation agent 0.3-0.5 part
Mineral additive 96-98 part.
Further, described grouting agent composition and mass fraction thereof comprise:
2.5 parts of water reducers
0.4 part, microdilatancy powder
0.4 part of anti-sedimentation agent
97 parts of mineral additives.
Further, described water reducer comprises the poly carboxylic acid of powder.
Further, described microdilatancy powder comprises vitriol.
Further, described anti-sedimentation agent comprises soap.
Further, described mineral additive comprises flyash and micro-silicon ash.
A kind of preparation method of the described hole path pressure grouting agent for highway, described preparation method is: take in proportion water reducer, microdilatancy powder, anti-sedimentation agent and mineral additive and added in batch mixing stirrer, stir, just obtain the described hole path pressure grouting agent for highway.
Further, on batch mixing stirrer, be connected with air-inducing dust-removing equipment.
Further, the batch mixing stirrer that described batch mixing stirrer is volume 1000L-2000L.
The invention provides a kind of hole path pressure grouting agent for highway and preparation method thereof, its beneficial effect mainly having is: the advantages such as its slurry of hole path pressure grouting agent of preparing by the inventive method is full, not fast, the microdilatancy of bleeding, flow velocity, construction are smooth, use manpower and material resources sparingly and reduce that secondary is done over again, have important using value.
