Abstract
The present invention relates to a technology for a concrete pumping agent. The existing concrete pumping agent is prepared from a single component water reducing agent and a retardation agent and has the defects of poor cement adaptation, poor fluidity, crystal separation under low temperature in winter, pipeline blockage caused by precipitation, abnormal use, extremely instable quality and rapid slump constant loss, and the present invention provides a concrete pumping agent compounded by a multiple water reducing agent and a multi-component retardation component and a preparation method thereof. The concrete pumping agent has the technical scheme that the concrete pumping agent comprises the compositions in weight ratio: 15 to 73 of naphthalenesulfonic acid formaldehyde condensation product, 8 to 50 of sulfamate, 20 to 50 of fatty group hydroxy sulphonate, 0.2 to 0.7 of sodium dodecylbenzene sulfonate, 0 to 1.5 of sodium tripolyphosphate, 0 to 1.5 of sodium hexametaphosphate, 0 to 2 of sucrose and 10 to 20 of water. The concrete pumping agent has the preparation method that the water is added in a reaction kettle to be heated according to the weight ratio, the sodium tripolyphosphate, the sucrose, the sodium hexametaphosphate and the sodium dodecylbenzene sulfonate are orderly added to be stirred, the naphthalenesulfonic acid formaldehyde condensation product, the sulfamate and the fatty group hydroxy sulphonate are stirred and cooled to 23(+/-)3 DEG C, and the concrete pumping agent is obtained.
Description
One, technical field
The present invention relates to a kind of concrete technology, especially a kind of concrete pump-feed agent and preparation method.
Two, background technology
At present used concrete is generally provided by large-scale stirring station in construction work, help the control of quality and enhance productivity, labour intensity is low, the duration is short, noise is low, airborne dust is few, be beneficial to advantage such as environmental protection.General concrete all adopts the technology of pumping to pour into a mould at the construction field (site), therefore need concrete to have good flowability and pumpability, but because the concrete of stirring station is to be transported to the working-yard by truck mixer from stirring station, in case traffic jam or road are far away, mobile heavy losses can take place and can't pumping in the overlong time of the concrete that stirs experience.At present the aqua concrete pump-feed agent of selling on the market adopts single-component water reducer and retardant formulated more, thereby there is a following shortcoming: inferior suitability, usually can only adapt to the minority cement type, mobile bad, (composition is Na to separate out crystal under the winter low temperature condition
2SO
4Or CaSO
4), precipitation, cause line clogging, can't normally use, simultaneously, quality is extremely unstable, slump-loss is fast.At number of patent application is 200410016574.4, discloses " a kind of control slump-loss type high performance concrete pumping agent " patented technology, adopts the single-component water reducer, still exists above-mentioned weak point.
Three, summary of the invention
The purpose of this invention is to provide and a kind ofly can even more normally under the low temperature use non-crystallizablely, can adapt to 90% above cement type at 0 ℃, good fluidity, cost is low, polynary water reducer and many components slow setting composition compound concrete pump-feed agent and preparation method.
The technical scheme that purpose of the present invention is taked is to be made up of following constituent and weight ratio:
Concentration is 38% naphthalene sulfonic acidformaldehyde condensation product 15-73
Concentration is 38% sulfamate 8-50
Concentration is 30% aliphatic hydroxyl sulphonate 20-50
Sodium dodecylbenzene sulfonate 0.2-0.7
Tripoly phosphate sodium STPP 0-1.5
Sodium hexametaphosphate 0-1.5
Sucrose 0-2
Water 10-20
Preparation method of the present invention is as follows:
By weight water is added in the reactor, be warmed up to 50 ℃-70 ℃, add tripoly phosphate sodium STPP, sucrose, sodium hexametaphosphate and Sodium dodecylbenzene sulfonate successively, stir 30-40min, after material is dissolved fully, add naphthalene sulfonic acidformaldehyde condensation product, sulfamate, aliphatic hydroxyl sulphonate again, behind the stirring 15-25min, cool to 23 ± 3 ℃, promptly get concrete pump-feed agent.
Naphthalenesulfonate formaldehyde condensation compound water reducer used in the present invention, sulfamate water reducer, aliphatic hydroxyl sulphonate water reducer are high efficiency water reducing agent, belong to anion surfactant, and its effect is to disperse cement granules.Sodium dodecylbenzene sulfonate is an air entrapment agent, is mainly used in to reduce concrete pumping resistance, prevents concrete water bleeding, segregation, improves impervious, freezing and thawing performance simultaneously.Tripoly phosphate sodium STPP, sodium hexametaphosphate, sucrose are retardant, regulate concrete coagulating time.
Starting material used herein are easy to get, and cost is low, effectively improve concrete pumping and keep mobile, pumpability in the long period.Be widely used in structures such as commodity ready-mixed concrete, mass concrete, Steel Concrete, light aggregate concrete, bridge, building, water conservancy project and road surface.
Four, embodiment
Further specify the present invention below in conjunction with embodiment.
Fetch water by weight and 13.8 add in the reactors, after being warming up to 60 ℃, add tripoly phosphate sodium STPP 0.25, sucrose 0.15, sodium hexametaphosphate 0.3 and Sodium dodecylbenzene sulfonate 0.5 successively, stir 30min, after material is dissolved fully, add concentration again and be 38% naphthalene sulfonic acidformaldehyde condensation product 25, concentration and be 38% sulfamate 20, concentration and be 30% aliphatic hydroxyl sulphonate 40, stir 15min after, cool to 23 ℃, promptly obtain concrete pump-feed agent.
Concrete pump-feed agent is delivered to the check of Chongqing City construction project quality test test center, check conclusion: this product is checked by examining concrete performance among " concrete pump-feed agent " JC473-2001, satisfies the requirement of acceptable end product performance index.
