Abstract
The invention discloses an anti-cracking modifier for concrete, which is prepared from the following raw materials in parts by weight: 1.5-2.8 parts of diethylenetriamine, 5-10 parts of sodium fluosilicate, 2.5-3.7 parts of sodium lauryl sulfate, 2.2-3.5 parts of 4-p-phenylphenol, 0.8-1.6 parts of zinc borate, 2.3-4.9 parts of bis-tert-butyl diisopropyl benzene peroxide, 1.2-2.4 parts of acetyl tributyl citrate and 0.5-1.5 parts of benzoic acid. The modifier has the advantages of high-temperature anti-rut property and low-temperature anti-cracking property; the modifier can enhance the summer anti-rut capacity and winter anti-cracking capacity of the unmodified asphalt concrete, and has lower cost than like products; the modifier enables the construction quality of the asphalt concrete to exceed the strength and service life of common asphalt concrete, and has favorable compatibility for asphalt and stone; and the modifier can be used for building new roads, and can also be used for roadway maintenance.
Description
Technical field
The present invention relates to a kind of concrete anticracking properties-correcting agent, belong to building material field.
Background technology
At present not high enough for building anti-carrying capacity and the sustainability of bituminous concrete of road, cause the aspects such as high temperature rut, cold cracking, Moisture Damage and weather resistance often to go wrong.The domestic roads such as motorway, national highway and high-grade highway that built up often need maintenance and medium-term and long-term overhaul, so not only increased the comprehensive cost of Road construction and maintenance, and affect the transport power of road, in the long run consider also to have affected the efficiency of Material Transportation, the fast development of national economy, road traffic has also been formed to a kind of restriction.
Summary of the invention
The deficiency existing for prior art, technical problem to be solved by this invention is, a kind of concrete anticracking properties-correcting agent is provided, and intensity is high, and resistance to cleavage is good, long service life.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is, a kind of concrete anticracking properties-correcting agent,
Raw material by following parts by weight is made: diethylenetriamine 1.5-2.8 part, Sodium Silicofluoride 5-10 part, sodium lauryl sulfate 2.5-3.7 part, 4-p-phenyl phenol 2.2-3.5 part, zinc borate 0.8-1.6 part, dual-tert-butyl peroxidation diisopropyl benzene 2.3-4.9 part, tributyl acetylcitrate 1.2-2.4 part and M-nitro benzoic acid 0.5-1.5 part.
Optimize, above-mentioned concrete anticracking properties-correcting agent, by the raw material of following parts by weight, made:
1.3 parts of 1.8 parts of diethylenetriamines, 7 parts of Sodium Silicofluorides, 3.2 parts of sodium lauryl sulfates, 2.8 parts of 4-p-phenyl phenols, 1.1 parts of zinc borates, 4.5 parts of dual-tert-butyl peroxidation diisopropyl benzenes, 2 parts of tributyl acetylcitrates and M-nitro benzoic acids.
The present invention compares with existing properties-correcting agent, has the following advantages: the anti-rut of high temperature, low temperature cracking resistance; Use 4-p-phenyl phenol can make unmodified bituminous concrete originally improve at the rutting resistance in summer and the cracking resistance trace energy force rate in winter; Low with like product comparative costs; Use dual-tert-butyl peroxidation diisopropyl benzene can make the construction quality of bituminous concrete over intensity and the work-ing life of general bituminous concrete, good to the compatibility of pitch and building stones; Be applicable to any domestic heavy traffic paving asphalt, pitch wax content is not required, be applicable to various physicalies building stones up to standard, the acid-basicity of building stones is not required, both can be for newly-built road, again can be for pavement maintenance & rehabilitation.
