Abstract
The invention discloses crack-preventing asphalt concrete which comprises the following raw materials in parts by weight: 100 parts of cement, 30-35 parts of asphalt, 10-13 parts of coarse aggregates, 8-11 parts of fine aggregates, 3-6 parts of diphenol propane type epoxy resin, 2-5 parts of sodium sulfide, 0.5-2 parts of diphenylcarbohydrazide and 0.02-1 part of chloropropane. The crack-preventing asphalt concrete disclosed by the invention is not specially preserved in the preserving process. However, no matter how the three phases of the concrete change, crack of the concrete is not affected even if the liquid phase is lost, evaporated and absorbed by the solid phase.
Description
Technical field
The present invention relates to a kind of concrete.
Background technology
Concrete is heterogeneous three-phase body, i.e. solid, liquids and gases.Two kinds of faces that contact are called interface, and the existence of concrete median surface is unavoidable, and concrete performance is produced to detrimentally affect.The shared volume of concrete mix three-phase is roughly, solid phase account for cumulative volume 73% ~ 84%, liquid phase accounts for 15% ~ 22%, gas phase accounts for 1% ~ 5%.The volume of three-phase is not unalterable, and in the setting and harden process after building, the shared volume of three-phase will constantly change, but final set changes minimizing later, show as cumulative volume and liquid phase and reducing, and gas phase is increasing, and is mainly that liquid phase runs off, evaporates and absorbed and cause by solid phase.In addition, the volume of three-phase also can change with the variation of envrionment conditions.The change of three phase volumes is that concrete produces crack one of the main reasons, and especially concrete produces final set before comparatively obviously (it has been generally acknowledged that accompanies shrinks, the crack that dry shrinkage etc. cause).
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, provide solidify after the bituminous concrete of the anti-chap in crack not.
Object of the present invention is carried out specific implementation by the following technical programs:
A kind of bituminous concrete of anti-chap, each component of its raw material by weight, 100 parts of cement, pitch 30-35 part, coarse aggregate 10-13 part, fine aggregate 8-11 part, propane type epoxy resin of di phenolic group 3-6 part, sodium sulphite 2-5 part, phenylbenzene phosphinylidyne two hydrazine 0.5-2 parts, propenyl chloride 0.02-1 part.
As preferred version, the bituminous concrete of above-mentioned anti-chap, each component of its raw material by weight, 100 parts of cement, 35 parts of pitches, 12 parts of coarse aggregates, 10 parts of fine aggregates, 4 parts of propane type epoxy resin of di phenolic group, 3.5 parts, sodium sulphite, 1.5 parts of phenylbenzene phosphinylidyne two hydrazines, 0.4 part of propenyl chloride.
During use, after raw material is fully mixed by weight, by normal health-preserving method health.
Beneficial effect of the present invention:
The bituminous concrete of anti-chap of the present invention, in health process, without special maintenance, no matter how concrete three-phase changes, even if liquid phase runs off, evaporates and absorbed by solid phase, can not affect concrete dry and cracked.
