The invention discloses a kind of highway crack resistence plain concrete, raw material includes：Cement, rubble, expanded slag, coarse sand, scoria, conch meal, agstone, gypsum, glass fibre, vinal, multi-walled carbon nanotube, polycarboxylate water-reducer, triethanolamine, prodan, rosin resin, sodium alkyl benzene sulfonate, water.A kind of highway crack resistence plain concrete proposed by the present invention, bearing, crack resistence and durability are good, can effectively improve the service life of highway.
Description
Technical field
The present invention relates to technical field of concrete more particularly to a kind of highway crack resistence plain concretes.
Background technique
Concrete refers to the general designation of the cementing integral engineered composite material of aggregate by cementitious material (cement), has become
For one of modern times the most widely used construction material.Concrete has greatly speeded up the hair of national infrastructure project since the appearance
Exhibition, the especially development of highway construction.Due to highway environment complexity, its bearing tool there are certain requirements, the plain coagulation of highway
Soil is all commonplace at home and abroad because of the accident of highway cracking damage caused by Material degradation, and becomes worse, and therefore, grinds
Make a kind of highway crack resistence, plain concrete with long service life is current urgent problem.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of highway crack resistence plain concretes, hold
Principal characteristic, crack resistence and durability are good, can effectively improve the service life of highway.
A kind of highway crack resistence plain concrete proposed by the present invention, raw material include by weight：Cement 140-180
Part, 480-540 parts of rubble, 30-40 parts of expanded slag, 440-520 parts of coarse sand, 30-50 parts of scoria, 10-20 parts of conch meal, stone
15-25 parts of limestone flour, 1.5-3 parts of gypsum, 2-5 parts of glass fibre, 2-5 parts of vinal, 1-3 parts of multi-walled carbon nanotube,
0.6-1.2 parts of polycarboxylate water-reducer, 0.2-0.5 parts of triethanolamine, 1-2 parts of prodan, 0.1-0.4 parts of rosin resin, alkyl
0.1-0.4 parts of benzene sulfonic acid sodium salt, 85-120 parts of water.
Preferably, raw material includes by weight：150-170 parts of cement, 490-520 parts of rubble, expanded slag 32-38
Part, 460-500 parts of coarse sand, 35-45 parts of scoria, 12-18 parts of conch meal, 18-22 parts of agstone, 2-2.5 parts of gypsum, glass
3-4 parts of fiber, 3-4 parts of vinal, 1.5-2.5 parts of multi-walled carbon nanotube, 0.8-1 parts of polycarboxylate water-reducer, three ethyl alcohol
0.3-0.4 parts of amine, 1.2-1.8 parts of prodan, 0.2-0.3 parts of rosin resin, 0.2-0.3 parts of sodium alkyl benzene sulfonate, water 95-
110 parts.
Preferably, raw material includes by weight：160 parts of cement, 500 parts of rubble, 35 parts of expanded slag, 480 parts of coarse sand,
40 parts of scoria, 15 parts of conch meal, 20 parts of agstone, 2.2 parts of gypsum, 3.5 parts of glass fibre, 3.5 parts of vinal,
2 parts of multi-walled carbon nanotube, 0.9 part of polycarboxylate water-reducer, 0.35 part of triethanolamine, 1.5 parts of prodan, rosin resin 0.25
Part, 0.25 part of sodium alkyl benzene sulfonate, 100 parts of water.
Preferably, the partial size of rubble is 15-30mm.
Preferably, polycarboxylate water-reducer is prepared by following technique：By methoxy polyoxyethylene ether, prenol polyoxy
Vinethene mixing, is then added vitamin C, benzoyl peroxide, acrylic acid, mercaptoethanol, methylpropene sodium sulfonate, and stirring is anti-
It answers, suitable quantity of water is then added, regulation system pH value obtains polycarboxylate water-reducer.
Preferably, polycarboxylate water-reducer is prepared by following technique：By weight by 20-40 parts of methoxy polyoxyethylenes
Ether, 20-40 parts of isoamyl alcohol polyoxyethylene ether mixing, control system temperature are 35-40 DEG C, and 0.2-0.4 parts of dimension lifes are then added dropwise
Plain C, 0.1-0.2 part of benzoyl peroxide, 50-80 parts of acrylic acid, 0.6-0.8 parts of mercaptoethanols, 5-8 parts of methacrylic sulfonic acids
Then suitable quantity of water is added in sodium, insulation reaction 1-1.5h after completion of dropwise addition, regulation system pH value is 5-6, obtains polycarboxylic acids diminishing
Agent.
Preferably, time for adding 40-50min.
Inventive article is made using conventional fabrication process.
By rationally adding rubble, expanded slag, coarse sand, scoria, conch meal and agstone, each component in the present invention
Cooperation, using the difference of its partial size, realizes in concrete and is sufficient filling with, reduce the gap between each component particle, improves
Concrete institutional framework keeps concrete more closely knit, improves the impermeability, air-tightness and early strength of concrete, then cooperates
Glass fibre, vinal and multi-walled carbon nanotube are added, the uniform random distribution in concrete further improves mixed
Solidifying soil pore structure and compaction rate, moreover it is possible to stress is concentrated when eliminating because moisture loss bring adversely affects, and can extenuate load-bearing,
Tend to stress distribution uniformly, effectively bearing, crack resistance, wearability and the later strength of enhancing concrete of the present invention, coagulation
Native durability improves；Again by rationally adding polycarboxylate water-reducer, wherein use methoxy polyoxyethylene ether, prenol
Polyoxyethylene ether mixing, is then added vitamin C, benzoyl peroxide, acrylic acid, mercaptoethanol, methylpropene sodium sulfonate, stirs
Reaction is mixed, suitable quantity of water, regulation system pH value, the resistance to storage of obtained polycarboxylate water-reducer, in concrete of the present invention is then added
It is good with good compatibility, dispersibility and dispersion retentivity, match with gypsum, triethanolamine, rosin resin, sodium alkyl benzene sulfonate
Close, advanced optimize concrete institutional framework of the present invention, improve the mobility of concrete of the present invention, pumpability, education resistance and
Workability improves concrete permeability resistance, weatherability and crack resistance of the present invention.By cooperating between each material in the present invention, have
Synergistic effect makes concrete of the present invention have excellent bearing, crack resistence and durability, meets performance needed for highway, energy
