Abstract
An water-permeable concrete brick suitable for high-load pavement features that the polymer and high-hydroscopicity and-strength shale ceramsite are used to modify the sand-free porous cement concrete for improving elasticity, adhesive to aggregate, mechanical performance and durability.
Description
Technical field
The invention belongs to a kind of water-permeable road brick.
Background technology
The honeycombed cement concrete road surface has a series of advantage: good draining, anti-skidding and anti-acoustic capability have obtained application in many occasions.But owing to following two shortcomings have limited its further broadened application:
(1) the honeycombed cement mechanical properties of concrete is relatively poor, and especially the elasticity of cement slurry is relatively poor, can not bear the traffic dynamic stress, thereby weather resistance is bad, never obtains to use on the trap for automobile road surface.
(2) the honeycombed cement concrete is owing to the scope of application of moisture consumption in its proportioning raw materials is very narrow, thereby make the moisture consumption be difficult to control, mortality is higher when causing the production of road surface cast in situs of honeycombed cement concrete permeable or honeycombed cement concrete road pavement brick, has also limited the broadened application of honeycombed cement porous pavement.
Summary of the invention
, moisture consumption unmanageable shortcoming relatively poor at above-mentioned honeycombed cement mechanical performance of concrete; the invention provides a kind of production method of porous ceramicite concrete permeable brick; with the porous ceramicite concrete permeable brick water-permeable and air permeable that this method is produced, cohesive strength height, good endurance.
The technical solution adopted for the present invention to solve the technical problems is by the mode of working along both lines the honeycombed cement concrete to be carried out modification:
First pipe: the honeycombed cement concrete is carried out modification by adding polymkeric substance, improve the elasticity of cement slurry and the bonding of cement slurry and aggregate, do not influence simultaneously concrete ultimate compression strength again, improved the mechanical property and the weather resistance of cellular concrete greatly, thereby made the honeycombed cement concrete can be used for trap for automobile etc. than heavy traffic load road surface.
The polymkeric substance that can be used for the cellular concrete modification has benzene emulsion, pure acrylic acid emulsion, styrene-butadiene emulsion and epoxy resin etc., and should select near second-order transition temperature (Tg) kind of (20～40 ℃) room temperature.Because if second-order transition temperature is too high, polymkeric substance can not film forming in concrete, can only play filling effect, to not contribution of mechanical property.If second-order transition temperature is too low, then, be unfavorable for concrete ultimate compression strength because polymkeric substance is softening at ambient temperature.
Second pipe: in the concrete crushed stone aggregate of no sand honeycombed cement, add the high-strength haydites of book structure of a certain proportion of water-absorbent and form combined aggregate.
Haydites of book structure inside and surface have crackle and micropore, and these holes were filled up by air originally, but with fresh water mud mix, haydite will absorb the moisture in the grout, makes the haydite volume of voids dwindle; And grout condenses and when sclerosis, and grout will absorb the moisture in the haydite hole, makes the haydite volume of voids of cement slurry parcel increase, and microtubule pressure reduces, thereby is lower than external pressure.Rely on this " from vacuum " process, the boundary strength and the adhesive property of haydite and cement slurry are increased, and the mechanical property of cellular concrete is strengthened.
Simultaneously, haydites of book structure has stronger water-absorbent, has reduced separating out of grout, has reduced the risk that the grout of the permeable space of the permeable brick of cellular concrete being separated out in the preparation stops up, thereby the moisture that has enlarged the cellular concrete pavior brick is suitable for proportional range, increases its applicable performance.
This porous ceramicite concrete permeable brick can use general road brick mould of plastics can not make permeable brick surface layer voidage reduce as production mould, and water-permeable weakens.
The proportioning of this porous ceramicite concrete permeable brick sees Table 1.
Table 1 porous ceramicite concrete permeable brick prescription
