Description
Technical field
The present invention relates to be used for the new and effective economic water-proof material of highway, bridge, house, underground works, be specifically related to a kind of semi-rigid leakproof paste.
Background technology
Highway, bridge, house, the extensive water-proof material that adopts of underground works have rigidity and flexible waterproof material two big classes usually at present, as water-proof concrete, fibrous concrete, modifying asphalt, resinous polymer etc., rigidity water-proofing material such as water-proof concrete and fibrous concrete will occur seepage because the material porosity is big, compactness and relatively poor with the cementability of structure in case produce microfracture; Modifying asphalt class material and structure primary structure are bonding better, but temperature difference adaptability and ageing resistance are relatively poor, and the waterproof time limit is subjected to bigger limitation; It is better that polyester material is compared effect, but construction is complicated, cost is high, and range of application is subjected to certain restriction.Although at present water-proof material is of a great variety, cost performance is good, and construction technology is simple, and water resistance is good, and freeze proof, heat resistanceheat resistant, the anti-aging impervious material that can both take into account are still rare, obviously can not adapt to the needs of economic construction.
Summary of the invention
Purpose of the present invention aims to provide a kind of good seepage-proof property, cost is low, construction technology is simple, and high-temperature stability, low-temperature cracking-resistance and ageing-resistant performance are good, the semirigidity activated serial leakproof paste that cost performance is high.
The object of the present invention is achieved like this: semirigidity activated leakproof paste, mix by various active micro mist and pitch, wherein also add fiber and cement additive, its proportioning is by weight: activate micro powder 100～300: pitch 50～200: fiber 0.01～0.1: admixture 0.03～0.5;
Wherein, activate micro powder refers to specific surface area 600m
2The combination of special thin cement, slag micropowder, the former powder of flyash, silicon ash and sand that/kg is above, its component is counted with weight ratio: cement 30～60, breeze 10～40, flyash 10～40, silicon ash 5～20, sand 80～120; Pitch refer to according to the structure needs adopt split soon type, in split type, slowly split type, split the fast type emulsified bitumen that coagulates slowly; Fiber is meant the polyester defend and split fibre;
Admixture is meant cement water reducing agent, diminishing hardening accelerator, retardant etc.
Can provide the series that satisfies different needs prescription according to thinking of the present invention, as:
1, flexible partially semirigidity activated leakproof paste, form by the following weight ratio composition:
Cement 50, breeze 25, flyash 15, silicon ash 10, sand 100, fiber 0.1, admixture 0.4 splits the fast type emulsified bitumen 200 that coagulates slowly.
2, inclined to one side inflexible semirigidity activated leakproof paste, form by the following weight ratio composition:
Cement 50, breeze 25, flyash 15, silicon ash 10, sand 100, fiber 0.1, admixture 0.4 splits type emulsified bitumen 80 soon.
Key problem in technology of the present invention is emulsified bitumen and the reaction of activate micro powder additive material appropriate proportioning, the high compactness impervious material that generates, it has good anti-low-temperature cracking, high-temperature stability, corrosion-resistant, ageing resistance good, do not heat, free from environmental pollution, with primary structure bonding firmly, easy construction, construction costs is low, the cost performance advantages of higher.Also have many people in emulsified bitumen, to add different materials before comparing and comprise cement, but their adding cement etc. only have been the effects of weighting agent.The present invention is actually a kind of activate micro powder concrete and emulsified bitumen and carries out physical-chemical reaction generate a kind of novel secondary rack on the basis of one-level rack, filling is between the one-level rack, the elasticity rack of rigid material and the visco-plasticity rack of flexible materials cross one another, constitute bullet plasticoviscosity rack, formed a kind of hard and soft dense material that combines.
Compared to existing technology, the present invention has the following advantages:
(1) compactness height, its infiltration is highly almost nil.
(2) cold cycle, resistance to cleavage are good.
(3) high temperature stability performance is good.
(4) good with the primary structure adhesive property.
(5) corrosion resistance and good.
(6) resistance of aging is strong, and Years Of Service is long.
(7) construction costs is low, the cost performance height.
(8) need not heat, free from environmental pollution, energy-saving and environmental protection are profitable, easy construction.
(9) crumbly coefficient can be adjusted between 3～5 according to the structure needs, can just can soften.
(10) be widely used in antiseepage, leakproofs such as highway, bridge, tunnel, house, the application industry field is wide.
Description of drawings
Fig. 1 is that the present invention uses process flow sheet.
