The method that material preparation subtracts jelly.
Background technique
Main raw material(s) of the cement as construction industry, dosage is huge, and cement industry energy consumption is high, heavy-polluted asks
Topic protrudes, and runs counter to the requirement of Green Development.At this stage, rationally using resource, reduce cement usage amount can yet be regarded as one it is good
Good solution.It is a kind of emerging concrete function additive that concrete, which subtracts jelly, and main function is to reduce cementitious material to use
The 10wt%-15wt% of amount, and keep the mobility and later period strength grade of concrete of concrete.Subtract jelly and other concrete
Additive matches, and improves concrete workability, keeps strength grade of concrete, saves the dosage of cement in engineering construction.
Water-reducing agent is the necessary component of high performance concrete, it is ensured that concrete has preferable mobility, is dispersed, still
Due to the limitation of water-reducing agent itself, it is difficult to be imitated by improving the measure of reduction gel material content of water-reducing agent dosage
Fruit, and the problem of isolating bleeding may be brought.Micro- collection that water-reducing agent can not disperse can be acted on by subtracting the general component in jelly
On material, micro disperse effect is generated.Containing a large amount of low molecular weight sugars in carbohydrate leftover bits and pieces, saccharide compound has polyhydroxy structure,
It with good water holding capacity, while can also be adsorbed on some cement granules, generate micro disperse effect, can also be used as and subtract
The component of jelly improves its surcharge.
Patent CN105293983A discloses a kind of high-adaptability concrete with jelly is subtracted, by alcohol amine compound, melamine
Amine system water-reducing agent, silica solution, alcohol aldehyde compound, alkali-resistant penetrant and water composition.The invention and polycarboxylic-acid, naphthalene system, fat
When race's water-reducing agent is used in combination, to the rheological property of cement-based gelling material mixture have it is slight increase effect, to mixture and
Yi Xingyou improvement result.Alcohol amine compound, alcohol aldehyde compound can be to C in the invention component3A、C4Hard mineral facies generate association to AF fastly
Same peptizaiton, silica solution can further excite C3S、C2S host phase hydration rate and process, melamine system water reducer are mended
Part diminishing effect is filled, and ensures that early strength is up to standard, alkali-resistant penetrant can centainly assist improving the infiltration of above-mentioned surfactant
Effect thoroughly.
Patent CN105198264A discloses a kind of energy-efficient Concrete synergist and preparation method thereof, by following weight

Wherein, UFD high-molecular copolymer is made of urea, formaldehyde, ten diphenyl sodium sulfonates.The energy-efficient concrete of the invention increases
Imitate agent can be improved strength grade of concrete, improves working performance by the coordination facilitation between each component, or protect
Hold working performance of concrete, strength grade it is almost the same in the case where reduce cement consumption, thus reach reduce coagulation scholar production
The purpose of cost, and then realize target that is energy-saving, reducing environmental pollution.
Patent CN105906230A discloses a kind of high performance concrete and subtracts jelly and preparation method thereof with multi-functional, by changing
Property polyethers, mixing hydramine, mixed alcohol, unsaturated acids, modified siloxane, initiator and water composition.The high-performance coagulation of the invention
Soil subtracts that be able to maintain strength grade of concrete while jelly reduces gel material content used in concrete constant with multi-functional, and
The durabilities such as frost resistance and the anti-carbonation of coagulation scholar can be improved.
It is different from the above prior art, the present invention introduces specific carbohydrate leftover bits and pieces in subtracting sizing agent component, using wherein
The design feature of the saccharide compound polyhydroxy of low molecular weight, auxiliary generate micro disperse effect, and jelly other components are common with subtracting
Effect achievees the purpose that reduce gel material content, environmentally protective, and can significantly reduce and subtract jelly cost.

Test
Using C30 concrete as blank example (table 1), cement is using new 42.5 ordinary portland cement of China, sand for test
The river sand that fineness modulus is 2.4, stone are the continuous grading rubble of 5-25mm, and water-reducing agent is common commercially available polycarboxylate water-reducer.
That adds embodiment 1-6 preparation respectively on the basis of blank example subtracts jelly, and compares with the blank example for not adding and subtracting jelly.
Concrete mixture characteristic is tested according to GB/T50080 " Standard for test methods of properties of ordinary concrete mixture standard "；Coagulation
Native intensity is tested according to GB/T50081 " standard for test methods of mechanical properties of ordinary concrete ".
1 C30 concrete mix of table (blank example)
| Cement | Flyash | Sand | Stone | Water | Water-reducing agent |
| 300 | 80 | 840 | 1010 | 160 | 7.8 |
Based on the C30 concrete of the match ratio preparation of blank example in table 1, does not change the match ratio of concrete, be added
Subtract jelly, volume is the 0.5wt% of gel material content, and concrete mixture characteristic and mechanical property test the results are shown in Table 2.
2 concrete performance experimental result of table
After what in C30 concrete it can be seen from test result in table 2 prepared by addition embodiment 1-6 subtracts jelly, concrete
Initial slump degree has improvement, and 7d, 28d and 60d intensity have growth.
The match ratio of concrete is adjusted, cement consumption is reduced, the jelly that subtracts that embodiment 1-6 preparation is added carries out concrete examination
It tests, concrete adjustment match ratio is shown in Table 3, and concrete mixture characteristic and mechanical property test the results are shown in Table 4 (blank example use originals
Match ratio, other embodiments are all made of match ratio after adjustment).
The adjustment of 3 C30 concrete mix of table
| Cement | Flyash | Sand | Stone | Water | Water-reducing agent | Subtract jelly |
| 300 | 80 | 840 | 1010 | 160 | 7.8 | 0 |
| 270 | 80 | 850 | 1020 | 157 | 7.8 | 1.7 |
Concrete performance experimental result after table 4 adjusts
Subtracting for embodiment 1-6 preparation is added it can be seen from test data in table 4 to reduce in cement consumption after jelly
In the case where 10wt%, concrete workability is still slightly better than blank example, and 28d intensity and 60d intensity all slightly increase.
In conclusion high-performance of the invention, which subtracts jelly, can significantly improve concrete mix workability, coagulation is improved
The compression strength of soil；Also cement consumption 10wt% or more can be reduced in the case where guaranteeing that concrete strength is constant simultaneously, thus
Cost is reduced, energy conservation and environmental protection has great economic benefit and social benefit.
