A kind of road and bridge engineering reinforcing high performance grouting material and preparation method thereof
Technical field
The invention belongs to building material technical field, specially a kind of road and bridge engineering reinforcing high performance grouting material.
Background technology
Grouting material be using high-strength material as aggregate, using cement as bonding agent, be aided with upper flow regime, microdilatancy, prevent from
The materials such as analysis are formulated.It adds a certain amount of water at the construction field (site), can be used after stirring.Grouting material needs to have
Have that self drainage is good, fast hard, early strong, high-strength, ungauged regions, microdilatancy;Nontoxic, harmless, not aging, to water quality and surrounding environment without dirt
Dye, from the features such as close property is good, antirust.There is reliable in quality in construction party face, reduce cost, shorten duration and easy to use etc. excellent
Point.Grouting material is widely used in the small gaps such as the back-grouting of Equipment Foundations, the grouting of steel structure column basis, track foundation and bonds filling
Slurry, subway, tunnel, underground engineering backhander method construction joint build-in, foot bolt fastening, the reinforcing of beams of concrete, post, plate, wall are repaiied
Supplementary irrigation is starched, and other normal concretes are difficult to irregular dead angle, corner and concrete porosity supplementary irrigation reparation poured into a mould etc..
Structural strengthening is widely used in concrete structure enlarged cross section with cement-based grouting material (referred to as reinforcing grouting material)
Product is reinforced.Grouting material is reinforced, is the added material for being used to improve concrete strength in engineering construction.The high-strength master for reinforcing grouting material
Technical indicator is wanted due to its particularity, to often require that reinforcing and repairing effect is good, the duration is soon and easy for structural strengthening repairing work
In construction the features such as.Thus, the requirement being embodied on grouting material be its fluidity, expansion rate, early stage and final strength and
The indexs such as setting time.
