Abstract
The invention discloses a kind of highway concrete admixture, contain alcohol-soluble resin in ingredient；The one kind of the alcohol-soluble resin in thermoplastic phenolic resin, Lauxite and polyvinyl butyral.The present invention provides a kind of highway concrete admixtures, include the component of following weight fraction, 20 30 parts of alcohol-soluble resin, 5 11 parts of guar gum, 25 parts of silica flour, 30 50 parts of slag.The highway concrete admixture of the present invention, is added to institute Pei Quan in concrete, can increase its impact resistance, wearability, greatly provides the durability of concrete.
Description
Technical field
The present invention relates to a kind of highway concrete admixtures, belong to road traffic engineering field.
Background technology
Concrete admixture kind is more, Various Functions.Using the additive of various different cultivars, can reach different
Effect, the workability for such as improving concrete, the freezing and thawing performance for improving maturing, be greatly lowered concrete use water
Amount, improve concrete strength, can compensate for concrete shrinkage, reduce concrete contraction fissure, improve concrete corrosion resistance,
Extend the service life of concrete, improve durability etc., it can be seen that concrete admixture effect it is huge.But concrete is additional
The construction quality that the type variety adoption of agent, addition manner etc. will seriously affect its concrete.
In recent years, as the process of urbanization, Integration of Urban-rural Areas are constantly accelerated, the effect of concrete admixture is increasingly
It is important.And it is well known that cement concrete material is one of current most large construction material, in we live, concrete
It is ubiquitous.Either the investigation station in road, bridge, building, harbour, harbour, dam, airport or the South Pole and the brill of ocean
Well platform, people can at every moment touch it, and cement concrete material is also used for outer space by scientist in research.
With the development of science and technology, requirement of the people to engineering technology, construction quality and building service life is more and more high.It uses
Concrete admixture is raising and improves concrete properties, meets the best, most effective, most easy of project durability requirement
One of approach.
Concrete admixture kind is more, Various Functions.Using the additive of various different cultivars, can reach different
Effect, the workability for such as improving concrete, the freezing and thawing performance for improving maturing, be greatly lowered concrete use water
Amount, improve concrete strength, can compensate for concrete shrinkage, reduce concrete contraction fissure, improve concrete corrosion resistance,
Extend the service life of concrete, improve durability etc., it can be seen that concrete admixture effect it is huge.But concrete is additional
The construction quality that the type variety adoption of agent, addition manner etc. will seriously affect its concrete.
There is particular/special requirement using concrete when the special engineerings such as highway, airfield runway, bridge road surface are built, generally
There is very high requirement to its slump, compression strength, flexural strength, shrinking percentage and rate of wear.And traditional mortar concrete
Either airfield runway etc. is frequently used the highway built by the high intensity such as vehicle or aircraft or high external pressure, is held
It easily collapses, surface abrasion is serious, and pavement roughness is caused to influence the normal of highway or airfield runway as time goes by
It uses, later period maintenance maintenance is thus needed to increase its cost.
Invention content
The technical problem to be solved by the present invention is to provide a kind of highway concrete for improving and improving concrete durability
Additive.
The invention discloses a kind of application of alcohol-soluble resin on highway concrete and its additive.Alcohol can be dissolved in
Class solvent but not soluble in water and hydrocarbon natural resin or synthetic resin.It is to prepare alcohol matter coating or alcohol varniss without drying oil
Important source material.The present invention is invented by many experiments, can be applied it on highway concrete admixture.
Alcohol-soluble resin of the present invention is in thermoplastic phenolic resin, Lauxite and polyvinyl butyral
It is a kind of.
The present invention also provides a kind of highway concrete admixture, contain alcohol-soluble resin in ingredient.
The highway concrete admixture, which is characterized in that alcohol-soluble resin is selected from thermoplastic phenolic resin, urea
One kind in urea formaldehyde and polyvinyl butyral.
Preferably, the present invention provides a kind of highway concrete admixtures, include the component of following weight fraction, alcohol
20-30 parts of soluble resin, 5-11 parts of guar gum, 2-5 parts of silica flour, 30-50 parts of slag.
Above-mentioned highway concrete admixture, is prepared by following process：
（1）Alcohol-soluble resin and guar gum are added in into reaction kettle, under the conditions of 110 DEG C, vacuumized, reaction system pressure is maintained at
1.5-1.9KPa reacts 1-2h, and organosilicon end hydroxy polyether polyalcohol and silica flour are then added in into reaction kettle, is stirred
It is even, 120-130 DEG C is warming up to, control reaction system pressure is vacuumized and is maintained at 1-2KPa, react 1-2h；
（2）After reaction, slag is uniformly mixed with the material stirring in reaction kettle additional to get the concrete of the present invention
Agent.
Beneficial effects of the present invention：
The highway concrete admixture of the present invention, is added to institute Pei Quan in concrete, can increase its impact resistance, resistance to
Mill property greatly provides the durability of concrete.
