Abstract

The invention discloses a concrete modifying agent. The concrete modifying agent is prepared from the following raw materials in parts by weight: 2.5-3.7 parts of sodium dihexyl succinic sulfonate, 1.3-2.6 parts of sodium stearate lactate, 0.5-1.6 parts of naphthalene water reducing agent, 2.3-4.6 parts of gum arabic, 2.5-4.5 parts of chlorosulfonated polyethylene, 1.2-1.8 parts of ammonium thiosulfate, 1.6-5.8 parts of carboxyl styrene-butadiene latex and 1.2-3 parts of ethylene propylene terpolymer rubber. Compared with the existing concrete modifying agents, the concrete modifying agent has the advantages that the surface toughness is high, the brittleness is low, and the low-temperature stability of concrete is improved; by using the concrete modifying agent, the coefficient of heat conductivity of the concrete is lowered, the heat absorption value is reduced, the heat/cold resistance value is increased, the temperature sensibility is lowered, the high/low-temperature stability of asphalt concrete becomes better, the crack resistance of a concrete paved pavement is improved, the service life of the paved pavement is prolonged, and the maintenance cost is reduced.

Description

A kind of for concrete properties-correcting agent
Technical field
The present invention relates to a kind ofly for concrete properties-correcting agent, belong to building material field.
Background technology
In recent years, bituminous highway career development is very fast, but the problem of bituminous pavement ubiquity technology and two aspects of quality, be mainly reflected in the weather resistance of highway engineering and the early stage infringement on road surface, especially severe at some weather condition and the larger section of traffic loading, therefore, the performance of bituminous concrete is had higher requirement.Conventionally, bituminous concrete must obtain the pitch through heating and the uniform mixture that thick, fine aggregate and packing material (breeze, cement etc.) form by suitable proportioning institute mix after compacting.Conventionally, the temperature stability of bituminous concrete is the principal element that affects highway weather resistance, the water stability of bituminous concrete is the principal element that affects Protective Measures of Bitumen Pavement Initial Damage, bituminous concrete pavement is because stability is bad, just there is a large amount of be full of cracks, hole groove, the obscission of peeling off, gather materials not reaching its design life, even form structural destruction, have to rebuilding or maintenance, cause the great wasting of resources and financial loss.
Summary of the invention
The deficiency existing for prior art, technical problem to be solved by this invention is to provide a kind of for concrete properties-correcting agent, good stability, the possibility that occurs be full of cracks, hole groove, the obscission of peeling off, gather materials within working life reduces greatly, has reduced maintenance cost.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is, a kind of for concrete properties-correcting agent,
Raw material by following parts by weight is made: dihexyl succinic acid sodium sulfonate 2.5-3.7 part, stearic acid Sodium.alpha.-hydroxypropionate 1.3-2.6 part, naphthalene water reducer 0.5-1.6 part, Sudan Gum-arabic 2.3-4.6 part, chlorosulfonated polyethylene 2.5-4.5 part, ammonium thiosulfate 1.2-1.8 part, carboxylic styrene butadiene latex 1.6-5.8 part and terpolymer EP rubber 1.2-3 part.
Optimize, above-mentioned for concrete properties-correcting agent, by the raw material of following parts by weight, made:
1.8 parts of 3.3 parts of dihexyl succinic acid sodium sulfonates, 2.4 parts of stearic acid Sodium.alpha.-hydroxypropionates, 1.2 parts of naphthalene water reducers, 3.8 parts of Sudan Gum-arabics, 3.2 parts of chlorosulfonated polyethylenes, 1.5 parts of ammonium thiosulfate, 3.2 parts of carboxylic styrene butadiene latexs and terpolymer EP rubbers.
The present invention compares with existing concrete modifying agent, and surface toughness is high, and fragility is low, improves concrete low-temperature stability; Use concrete thermal conductivity of the present invention to decline, heat absorption value reduces, and thermal resistance, cold resistance value improve, Temperature Susceptibility reduces, and the high low-temperature stability of bituminous concrete improves, and has improved the resistance to cleavage on concrete pavement road surface, increase the working life on the road surface of mating formation, reduced maintenance cost.
