Description
Technical field
The invention belongs to road and science of bridge building field, specifically a kind of polymer slag cement concrete can protected
Under conditions of demonstrate,proving the material other main pavement performance technical indicators and not reducing, concrete road surface or bridge floor are more significantly improved
Abrasion resistance.
Background technique
In the special area of some roads, if route profile radius is smaller, bus platform or tunnel road surface, large longitudinal slope
Deng the easy road surface for gathering around packet passage, road surface bears the repeated action of cross force and shear stress, road surface table often occurs
The permanent deformation of face transverse direction is embodied in wave, gathers around packet and passage, and then leads to safety and wear resistance decrease, thus
Lead to traffic accident, cause casualties and economic loss, especially in abrupt slope of growing up, minor radius zig zag, Heavy Traffic etc.
Special road section.And conventional method is that road pavement uses cement concrete pavement instead, for these special area cement-concrete roads
Face can cause flexural strength insufficient because rigidity is excessive and then cause easily to crack, and the abrasion resistance of road surface can be substantially
Decline, seriously affects the using effect on road surface, safety accident can be caused when serious.
Concrete is construction material most large in the world, is mainly formed by cementitious material, coarse-fine aggregate and water mix,
Middle aggregate occupies concrete overwhelming majority volume, and the superiority and inferiority of aggregate performance has the properties of concrete direct and significant
Influence.In recent years, the natural sand stone aggregate that China consumes every year is up to billions of tons, the imbalance of some areas supply-demand relationship
Also the price of sandstone aggregate is caused constantly to be promoted, in addition, the excessive exploitation and long-distance transport to sandstone have caused environment
Serious influence.It is asked in conclusion the substitute for seeking excellent sandstone aggregate has been that our face one is very important
Topic.At the same time, the amount that steel slag is shelved at present by China has reached 180 × 107Ton, and now also with annual millions of tons
Speed increases.China but only has 30% or so to the utilization rate of steel slag, and is mainly used as backfilling material, how preferably using residual
Remaining steel slag is a problem urgently to be resolved.It is used steel slag as the aggregate of concrete, is one for improving utilization rate of steel slag
Effective way.Due to containing dicalcium silicate, tricalcium silicate and ferrous aluminate isoreactivity minerals in steel slag, there is hydraulic gelling
Property, the water reactivity of cement concrete can be enhanced in the addition of steel slag, meanwhile, steel slag price is excellent honest and clean, has very big market
Advantage.
Summary of the invention
The object of the present invention is to provide a kind of polymer slag cement concrete, to solve existing road or bridge floor abrasion performance
The problem of performance deficiency.
To solve the above-mentioned problems, technical scheme is as follows: a kind of polymer slag cement concrete, feature
It is in terms of 100 parts of total weight, each parts by weight of raw materials proportion of the polymer slag cement concrete is as follows:
It the rest is water；
Wherein in polyphenylene sulfide lotion, in terms of 100 parts of total weight, each parts by weight of raw materials proportion is as follows:
Polyphenylene sulfide resin 37-56
Polyoxyethylene sorbitan laurate 1.5-3.0
It the rest is water.
Further, wherein water is ordinary tap water.
Further, the main component of polyphenylene sulfide resin is polyphenylene thioether, and purity is 60% or more, impurity
According to the difference of synthesis technology including but not limited to polyether-ether-ketone (PEEK), polysulfones (PSF) or polyimides (PI), polyphenylene
The relative density of sulfide resin is 1.0-1.4g/cm3.
The main component of above-mentioned polyphenylene sulfide resin is polyphenylene thioether, molecular structural formula are as follows:
Further, the polymer slag cement concrete also includes water-reducing agent and defoaming agent, and wherein water-reducing agent is steel
The 0-3 ‰ of slag weight, defoaming agent are the 0-3% of polyphenylene sulfide resin weight.
Further, the cement is ordinary portland cement, portland cement or sulphate aluminium cement.
Further, the steel slag is the waste residue making steel heel row and removing, including open hearth or converter slag.
Further, the sand is sandstone, limestone, basalt, diabase, aluminum ore fine aggregate, maximum aggregate size
For 0.6mm-2.36mm.
Further, the rubble is that limestone, basalt, diabase or aluminum ore fine aggregate, maximum aggregate size are
2.36mm-9.5mm。
The water-reducing agent is that the aqua or pulvis that portland cement concrete uses should make its effective component according to aqua
Reach above-mentioned weight requirement.Steel slag density is big compared with other aggregates, and the mobility for weakening concrete is added, to guarantee finished product
The construction property that concrete has had needs the amount according to steel slag that water-reducing agent is added.
The defoaming agent matches use with polymer used, and effective dose should be with the effective component phase of polyphenylene sulfide lotion
It is corresponding.Due to usually containing other polymers impurity such as polyether-ether-ketone, polysulfones etc., unpurified polyphenylene sulfide meeting in polyphenylene sulfide
Other unpredictable side reactions are brought, biggish surface tension can be brought in the process, generate foam, to reduce final coagulation
Native finished product inner air rate needs the effective dose according to polyphenylene sulfide that defoaming agent is added.
Water-reducing agent and defoaming agent are the prior art, and using general cement water reducing agent and defoaming agent, details are not described herein.
Polymer slag cement concrete of the invention has biggish bulk density, and setting time is compared with benchmark coagulation
Soil is slightly short, and mechanics, endurance quality and normal concrete are substantially close to the incorporation of polymer and steel slag improves cement concrete
Shrinkage performance, and stable long-term strength develops, and as age increases, growth rate is substantially better than normal concrete, and has
Lower alkali content and chloride ion content enhance flexural strength, compression strength and bend-press ratio, toughness while intensity increases
Apparent raising is obtained, also there is stronger abrasion resistance, apply and can get preferable durability on road surface and deck paving.
