Abstract
A kind of Superfluid state concrete is that a kind of Portland cement, flyash, particle diameter in 325-625 is that 0.5-2 centimetres stone, medium coarse sand, UWB-1 type retardation setting type flocculation agent, polyacrylamide, wooden calcium sulfonate and water is formed by label.The weight ratio of above-mentioned each component is: 500-700 kilograms of cement, flyash is 25-210 kilograms, water cement ratio is 0.4-0.7, sand coarse aggregate ratio is 0.4-0.6,500-700 kilograms of medium coarse sand, 333.3-1050 kilograms in stone, the agent 5.25-27.3 of UWB-1 type retardation setting type wadding, 0.053-0.91 kilogram of polyacrylamide, 0.53-2.73 kilograms of wooden calcium sulfonates.It is low that Superfluid state concrete of the present invention has a frictional coefficient, good fluidity, and anti-good dispersity, the intensity height, stone can suspend therein.
Description
The present invention puts it briefly and relates to a kind of concrete, specifically relates to a kind of Superfluid state concrete.
The concrete kind that building operation is used is a lot, as normal concrete, pump concrete, chutable concrete or the like.The normal concrete slump is lower.Be about 5-9 centimetre, needing reinforcement to vibrate could be closely knit, combines eakiness with surrounding soil with its dabbling concrete pile, moulds under the mud geologic condition soft, grout spreads loss easily, concrete can automatically shrink, and deep hole can't jolt ramming in addition, phenomenons such as pile body constriction, fracture may occur, particularly in the concrete perfusion pile driving construction, because heavy stone easily sinks, accumulates in the bottom in hole in normal concrete, forms more closely knit structure, can't insert skeletons such as Steel Reinforcement Cage.
Though the chutable concrete slump is higher, can reach about 20 centimetres, be convenient to pumping transportation and cast, the quality of the plastic concrete that is similar to slump 5-10 centimetre is arranged again, stone is many, viscosity is little, workability is poor but it contains.In the construction of pouring concrete pile, it is the same with normal concrete, and heavy stone easily sinks, and can not suspend, and more closely knit structure is formed on the bottom that accumulates in the hole, can't insert Steel Reinforcement Cage.In some construction technology, earlier concrete is pressed into the Kong Zhongzhi height in hole that do not collapse, and then puts into Steel Reinforcement Cage, under the situation of top penetration concrete, can form the darker plain concrete pile in bottom again, the reinforced concrete pile that top is short, thereby, the stake of poor quality, intensity is low.
It is low to the purpose of this invention is to provide a kind of frictional coefficient, good fluidity, closely knit automatically, viscosity is big, workability is good, can be in water from the construction that fall, polluted water not, intensity height, good endurance, the Superfluid state concrete that stone can suspend therein.
The objective of the invention is to realize by following manner:
A kind of Superfluid state concrete, by label is that stone, medium coarse sand, UWB-1 type retardation setting type flocculation agent, polyacrylamide, wooden calcium sulfonate and the water of a kind of ordinary Portland cement, flyash, particle diameter 0.5-2 centimetre among the 325-625 is formed, and above-mentioned each components by weight is:
Cement (kilogram) 500-700
Flyash (kilogram) 25-210
Water cement ratio 0.4-0.7
Water (kilogram) 210-637
Sand coarse aggregate ratio 0.4-0.6
Medium coarse sand (kilogram) 500-700
Stone (kilogram) 333.3-1050
UWB-1 type retardation setting type flocculation agent (kilogram) 5.25-27.3
Polyacrylamide (kilogram) 0.053-0.91
The 0.53-2.73 of wooden calcium sulfonate's (kilogram)
Superfluid state concrete advantage of the present invention is that frictional coefficient is low, good fluidity, and levelling is closely knit automatically voluntarily, anti-good dispersity can be from the construction that falls in water, the intensity height, and stone can suspend therein, when being used to pour into reinforced concrete pile, can enhance productivity greatly, reduce cost.
Other advantages of Superfluid state concrete of the present invention and details can be understood by reading the embodiment that hereinafter describes in conjunction with the accompanying drawings.
Embodiment:
With No. 425 ordinary Portland cement preparation Superfluid state concretes,
Its proportioning is as follows:
Cement (kilogram) 550
Flyash (kilogram) 100
Water cement ratio 0.5
Water (kilogram) 325
Sand coarse aggregate ratio 0.47
Medium coarse sand (kilogram) 553
Particle diameter 0.5-1.5 centimetre stone (kilogram) 624
UWB-1 type retardation setting type flocculation agent (kilogram) [notes] 6.5-19.5
Polyacrylamide (kilogram) 0.065-0.65
The 0.65-1.95 of wooden calcium sulfonate's (kilogram)
Annotate: the special additive of concrete under water is the product innovation of Engineering Technology Inst., China Petroleum ﹠ Natural Gas General Co's (No. 40, the Qu Jin pool, Tianjin City Tanggu highway) development.
Wherein, the particle diameter of stone can be defined between 0.5-2 centimetre, and this is for stone can be suspended in the concrete for preparing, and can be by concrete perfusion rig (application number the is CN93101250.3) discharge port of inventor's invention.The purpose that adds UWB-1 type retardation setting type flocculation agent is that the concrete for preparing is obtained is anti-dispersed, can be from the construction that fall in water, and levelling voluntarily, closely knit automatically and do not pollute the construction waters.
The purpose that adds polyacrylamide is the concrete cohesive force for preparing in order to improve, and reduces the fluid friction coefficient.
Wooden calcium sulfonate is a kind of water reducer, adds to its objective is in order to increase the slump, improves workability.
Its process for preparation is as follows:
1, weighs the weight of each component respectively by said ratio according to the concrete weight that needs in the construction to use;
2, the component except that wooden calcium sulfonate is mixed, mix under field conditions (factors) and stir.
3, added wooden calcium sulfonate in preceding about 10 minutes in pumping.
Only enumerated an embodiment above, in the process of actual concrete batching, its proportioning can be chosen in following scope:
Cement (kilogram) 500-700
Flyash (kilogram) 25-210
Water cement ratio 0.4-0.7
Water (kilogram) 210-637
Sand coarse aggregate ratio 0.4-0.6
Medium coarse sand (kilogram) 500-700
Particle diameter 0.5-2.0 centimetre stone (kilogram) 333.3-1050
UWB-1 type retardation setting type flocculation agent (kilogram) 5.25-27.3
Polyacrylamide (kilogram) 0.053-0.91
The 0.53-2.73 of wooden calcium sulfonate's (kilogram)
Wherein, wooden calcium sulfonate can replace with water reducer, and cement can use a kind of in No. 325-No. 625 the Portland cement.
Superfluid state concrete of the present invention is water insoluble, polluted waters not, intensity is up to the 200-350 kilograms per centimeter, good endurance, workability is good, and the slow setting time is 8-18 hour, and frictional coefficient reduces 60-90% than normal concrete, can be used for pouring into reinforced concrete pile, also can be used for productions such as beam, post, plate, be suitable for pipe-line transportation, be convenient to mechanized construction.Especially its stone can suspend in concrete, thus can be after jar be annotated concrete descending reinforcing cage, thereby improved mass of foundation.
