Description
Technical field
The present invention relates to concrete manufacturing field, more particularly to a kind of anti-crack concrete.
Background technology
At present, the thermal insulation material used on roofing includes extruded sheet, polyurethane coating, foam concrete, cinder, expansion
Perlite, foam glass waste and the polyphenyl pellet thermal insulation mortar for wall.Wherein, cinder, expanded perlite, foam glass
Glass waste is laxity material, and water absorption rate is high, and to install exhausting-gas hole, destruction is produced to waterproof layer after water suction, after water inlet
Poor thermal insulation property, to belong to national obsolete product.Extruded sheet is although cheap and is widest for roof heat insulation at this stage
Product, and heat-insulating property is preferable, but market now extruded sheet quality it is good it is excellent differ, shoddy phenomenon is serious, no fire prevention
The low price extruded sheet inferior of performance is still the mainstream in market, and the measured price of matter is also higher；And because extruded sheet is one piece of block
Be layered on roofing, be not pasted together with basic unit, easily departed from cement mortar screeding layer and basic unit, make screed-coat crack after water into
Enter basic unit, being directed at extruded sheet and being impregnated with reduces heat insulation effect in water, while also waterproof hidden danger is occurred.Polyurethane coating heat insulating ability
Can be good, but prevailing price is high, and cause serious pollution to the environment, smell is big, and to making, roofing overall cost is of high cost.There is polyphenyl pellet once in a while
Thermal insulation mortar is used in roof sections but because difficulty of construction is big, of high cost and dosage is few.Foam concrete heat-preserving looks for slope, although
Keep the temperature and look for slope and tool has great advantage in price, but because of construction machinery quality and construction personnel's technical problem, and existing rank
Section construction adds the mode of production of foaming agent using 100% cement, and finished product is not sufficiently stable in heat-insulating property, exists in construction
Many limitations, it is also relatively low in terms of integral strength and wearability, it is easy to crack.
The content of the invention
The technical problem to be solved in the present invention is to provide it is a kind of can be with cracking resistance, the impervious, anti-crack concrete that can keep the temperature.
In order to solve the above technical problems, the technical scheme is that：A kind of anti-crack concrete, its innovative point are：Press
Weight fraction proportioning is made of following components：
76-83 parts of cement, 32-37 parts of lime stone matter mountain flour, 44-47 parts of quartz sand, 10-20 parts of iron powder, nanometer silicon ash
11-16 parts, 3-5 parts of sodium sulfite part, 5-12 parts of flyash or slag powders, 150-180 parts of cobblestone, sepiolite 10-13
Part, 1-2 parts of water-reducing agent, 2.5-3 parts of water proof type polymer dispersion powder, 2-5 parts of penetrant crystalline activity masterbatch, durafiber 2-
3 parts, newborn 5-8 parts of the cement modifier of pulvis third.
Further, the quartz sand is the quartz sand of uf=1.5-2.5.
Further, the penetrant crystalline activity masterbatch is the active masterbatch of cement-based capillary crystalline waterproof coating.
Further, the newborn cement modifier of the pulvis third is the newborn modified cement of the pulvis third containing acrylic emulsion rubber powder
Agent.
The advantage of the invention is that：The formula of the present invention is ingenious in design, not only realizes good cracking resistance, impervious, insulation
The advantages of effect, and have energy-conserving profit waste, constructs and is limited from temperature and weather, and working procedure is simple, stable quality.
Novel concrete formula disclosed in this invention, the coal dust in original formula, pole are substituted using lime stone matter mountain flour
The big dependence alleviated to coal dust, reduces the production cost of concrete, improves economic benefit.
Mechanized construction can be used in construction, speed of application is fast, reduces space hold, substantially increases insulating product
Heat-insulating property and compressive property, while there is water proof anti-seepage, cracking resistance, adhesion strength are high.Reduce engineering cost and apply
Work cost, utilization to flyash or slag powders in the present invention, energy-conserving profit waste, economizes on resources.
