The mass percent of thing is 1%~3% of cement quality in the concrete allocated by the strength grade of concrete of engine request.
A kind of concrete of sulfate resistance physical erosion of the present invention, it is characterised in that:The acrylic acid polymer
The proportion of composing of middle acrylic acid crosslinked resin, water, glycerine and triethanolamine is：Contain acrylic acid in per 100g acrylic acid polymers
Crosslinked resin 6g, water 90g, glycerine 2g and triethanolamine 2g.
A kind of compound method of the acrylic acid polymer of the concrete of sulfate resistance physical erosion of the present invention, it is special
Levy and be:The compound method of the acrylic acid polymer 100g is as follows：
1. 2g glycerine is poured into 6g acrylic acid crosslinked resins, moistens acrylic acid crosslinked resin,
2. water 90g is added, is stirred, placed 2~3 hours, acrylic acid crosslinked resin is fully expanded,
3. 2g triethanolamines, regulation pH value to 6~7, acrylic acid polymer is added to prepare and complete.
The construction method of the concrete of sulfate resistance physical erosion of the present invention, including by the strong concrete of engine request
The perfusion of the concrete of degree grade allotment and the filling concrete of sulfate resistance physical erosion, it is characterised in that：The sulfuric-resisting
The filling concrete of salt physical erosion be the ground design elevation with construction ground as baseline, irrigate base respectively in baseline upper and lower surface
The concrete layer of the sulfate resistance physical erosion above the concrete layer and baseline of the sulfate resistance physical erosion below line, it is described
The concrete layer of the sulfate resistance physical erosion above the concrete layer and baseline of the sulfate resistance physical erosion below baseline
Thickness is not less than 30cm, by the concrete layer sulfur resistive respectively below baseline that the strength grade of concrete of engine request is allocated
Above the concrete layer of the sulfate resistance physical erosion below the concrete layer of hydrochlorate physical erosion and above line.
Principle of the invention is that there is acrylic acid polymer (PAA-VLMW) suppression physics salt knot is produced in concrete
Brilliant effect, using this effect of acrylic acid polymer (PAA-VLMW), is added into by the strong concrete of engine request
In the concrete of degree grade allotment, the destruction of sulfate physical erosion can be prevented and reduced；It is certain in ground surface in construction
(solution-air/gas-soil) irrigates the concrete of sulfate resistance physical erosion in region, improves the most heavy interface of sulfate physical erosion
The resisting erosion of sulfate ability in region, so as to strengthen the strength and stiffness of whole engineering structural system.
The beneficial effects of the invention are as follows：Raw material is easy to buying and cost is relatively low, concrete matched and than simple, and construction method is simple
Just, sulfate resistance physical erosion ability is strong.
Brief description of the drawings
Fig. 1 is the concrete construction structural representation of sulfate resistance physical erosion
In Fig. 1,1 is the concrete layer allocated by the strength grade of concrete of engine request, and 2 is ground design elevation, and 3 are
The concrete layer of the sulfate resistance physical erosion below baseline, 4 is the concrete layer of the sulfate resistance physical erosion above baseline.
Specific embodiment
