The application of Chinese honey locust in concrete
The present invention relates to the application of a kind of Chinese honey locust in concrete, particularly as the application of concrete air-entrainer.
Air entrapment agent is a kind of concrete admixture commonly used, also is one of main raw material of various composite additive for concrete.At present, China's air entrapment agent kind is few, poor performance, commonly used have a colophonium pyrolytic polymer, sodium alkyl benzene sulfonate etc., these products all are colloidal, and the on-the-spot dissolving difficulty of using more can not be compound with other dry powder admixture, so use face is restricted, the most compound additive or concrete of bleed of needing are all selected wooden calcium (calcium lignin sulphonate) water reducer for use, but wooden calcium water reducer, the one, resource-constrained, the 2nd, the bubble diameter that it is introduced is bigger, the small bubbles content useful to concrete strength is few, tends to reduce concrete strength after mixing, and reduces diminishing enhancing rate.Service condition from every side, up to the present, China's air entrapment agent exists all in the use that bubble is big, the unit volume number of bubbles is few, surely the bubble time short, mix problem such as inconvenience, cause defectives such as the concrete slump loss that mixes air entrapment agent is big, water retention property is poor, pumpability is bad, influence preparation high-grade concrete therefrom.
The objective of the invention is to Chinese honey locust is applied in the concrete as air entrapment agent or needs in the compound additive of bleed, thus improve effectively that the bubble that former air entrapment agent exists is big, the unit volume number of bubbles is few, surely the bubble time short and mix defectives such as the slump-loss that the back is produced in the concrete is big, water retention property is poor, pumpability is bad, influence preparation high-grade concrete.
The object of the present invention is achieved like this: Chinese honey locust is processed into powdery or aqua, mixes in the concrete or add the effect that can play air entrapment agent in the concrete with the compound back of other admixture.
Above-mentioned Chinese honey locust is processed into powdery and mixes two kinds of forms in the concrete:<1〉the Chinese honey locust oven dry is crushed to more than 100 orders, directly to mix in concrete, its incorporation is the 2-6 of cement consumption;<2〉with Chinese honey locust by fragmentation, immersion, boiling, pulp-extruding machine extrusion solution, to secrete press filtration, be concentrated into solid content be 30%-35%, be crushed to behind the roller drying more than 100 orders or after the spraying drying again and mix in the concrete, incorporation is the 0.5-1.5 ‰ of cement consumption.
Above-mentioned Chinese honey locust is processed into powdery and other admixture and mixes in the concrete after compound and be meant:<1〉make gas tracting subtractive agent with white sugar after compound and mix in the concrete, spaonin powder accounts for 15-30% in this water reducer, white sugar accounts for 70-85%, and the doping level of water reducer is the 5-8 ‰ of cement consumption when using;<2〉make gas tracting subtractive agent with saccharification calcium after compound and mix in the concrete, spaonin powder accounts for 5-15% in this water reducer, and saccharification calcium accounts for 85-95%, and the doping level of water reducer is the 10-15 ‰ of cement consumption when using.
Embodiments of the invention are by table 1, table 2, table 3 explanation.
Table 1 is Chinese honey locust air entrapment agent and Chinese honey locust gas tracting subtractive agent performance index test-results.
Table 2 is Chinese honey locust gas tracting subtractive agent and wooden calcium, sugared calcium wood calcium recombiner comparative test result.
Table 3 is used as pumping agent for the Chinese honey locust gas tracting subtractive agent or allocates the performance comparison test result of pumping agent into.
Now that table 1 is measured data and process of the test are described below as embodiment:
Embodiment 1: Chinese honey locust directly mixes in the concrete after being processed into powdery.
Detailed process: soak more than 8 hours with being placed on after the Chinese honey locust fragmentation in the water, in rotary spherical digester boiling 2-4 hour then, use the pulp-extruding machine extrusion solution again, secrete press filtration with secreting press, being concentrated into solid content at last is to adopt spraying drying to make spaonin powder behind the 30-35%, the spaonin powder that makes is mixed in the concrete, incorporation be cement consumption 7 ‰ (wherein spaonin powder is 1 ‰, saccharification calcium is 6 ‰), the cement that is adopted during test is ferry 625 cement, it is as shown in table 1 to mix data measured after stirring, water-reducing rate: 8%; Bleeding rate ratio: 52%; Air content 3.5%; Time of coagulation poor: initial set is 80min, and final set is 90min; Compressive strength rate: 3d is 110%, and 7d is 115%, and 28d is 118%; Shrinkage ratio: 125%; Relative durability index: 90%, can find out from institute's column data, Chinese honey locust has all reached acceptable end product among the existing air entrapment agent standard GB-8076-1997 of China as air entrapment agent on every index, thereby illustrate that Chinese honey locust is feasible as air entrapment agent, possess the condition that replaces existing various air entrapment agents fully.
Embodiment 2: Chinese honey locust is processed into powdery and saccharification calcium to be made gas tracting subtractive agent after compound and mixes in concrete.
Detailed process: the process of producing of spaonin powder is identical with embodiment 1, the spaonin powder that makes and saccharification calcium are mixed in the concrete after compound, incorporation is 12 ‰ of a cement consumption, wherein spaonin powder is 1 ‰, saccharification calcium is 11 ‰, testing used cement is ferry 625 cement, mixes that to stir the measured data in back as shown in table 1, water-reducing rate: 12%; Bleeding rate ratio: 48%; Air content: 3.8%; Time of coagulation poor: initial set is 110min, and final set is 115min; Compressive strength rate: 3d is 120%, 7d is 128%, 28d is 126%; Shrinkage ratio: 110%; Relative durability index: 92%, can find out from institute's column data, every index of Chinese honey locust gas tracting subtractive agent has all reached the acceptable end product among the existing gas tracting subtractive agent standard GB-8076-1997 of China, illustrates that the Chinese honey locust gas tracting subtractive agent can replace the existing various gas tracting subtractive agents that use fully.
Table 2 has been listed Chinese honey locust gas tracting subtractive agent and the more general comparison of other admixture on use properties of China's use at present in detail, in the table incorporation of admixture all with cement consumption as standard, from table, can find out, the Chinese honey locust gas tracting subtractive agent all is better than the various ordinary water-reducing agents that present China uses on every performance, illustrate that again Chinese honey locust is feasible as air entrapment agent and the compounded gas tracting subtractive agent of other admixture.
Table 3 has been listed Chinese honey locust gas tracting subtractive agent and other admixture as pumping agent or the comparison on use properties after allocating pumping agent into, in the table doping level of listed admixture all with cement consumption as standard.
Performance was all relatively poor when China used more general admixture to use as pumping agent at present, thereby cause the current pump concrete pumpability of China poor, pumping pressure is big, often obstruction, pump case and catheter wall pipe decrease big, pumping distance and highly limited and accident etc. often occurs, the application of Chinese honey locust gas tracting subtractive agent then can improve every index (listed as table 3) of pumping agent greatly, thereby significantly improves the performance and the quality of pump concrete.
When above-mentioned Chinese honey locust water reducer uses as pumping agent, need the requirement according to engineering, the label of cement and an amount of methylcellulose gum that add such as height and distance that concrete needs pumping sometimes.
Chinese honey locust also can be made into aqua among the present invention except that can be made into powdery; At some in particular cases, Chinese honey locust air entrapment agent and gas tracting subtractive agent need an amount of promoting agent and the suds-stabilizing agent of adding in use.
The present invention is owing to being applied in concrete as air entrapment agent Chinese honey locust or needing in the compound additive of bleed, thereby defective such as improved effectively that the bubble that exists in the former air entrapment agent is big, the unit volume number of bubbles is few, surely the bubble time is short, concrete anti-penetration grade and weather resistance have been improved greatly, increased the concrete slump, reduced bleeding, improve concrete pumpability, and reached all technical requirementss of GB GB8076-1997 air entrapment agent acceptable end product.
