Description
Technical field
It collapses effect the present invention relates to a kind of concrete production field more particularly to a kind of guarantor for improving concrete
With easy agent.
Background technique
When producing commerical ready-mixed concrete, the raw material needed are cement, sand, stone, water and chemical admixture, at present ring
Guarantor's policy is very severe, and high quality natural sand stone is limited, the mud containing excess in many poor quality sandstones.Sandstone factory is eluriating mud
In the process, in order to reuse water, flocculant can be added in the sewage eluriated, precipitates the mud in sewage as early as possible, so
After reuse upper layer clear water go eluriate sandstone, flocculant can be thus introduced in sandstone.Sandstone containing flocculant
It being transported to after concrete company, when for producing concrete, the adaptability of water-reducing agent and cement can be caused bad, such as
Collapsing reduces, and slump-loss is accelerated etc..So when producing concrete using this sandstone containing flocculant, just
It needs to be added the water-reducing agent than more one times or so under normal circumstances, increases the production cost and difficulty of construction of concrete.
It solves the above problems therefore, it is necessary to provide the new additive of one kind.
Summary of the invention
Effect the and easy agent in order to solve the above technical problems, the guarantor that the present invention provides a kind of for improving concrete is collapsed,
It in parts by weight include following component: 60-80 parts of water, 10-30 parts of sodium phosphate, industrial 1-5 parts of sucrose, triterpenoid saponin 2-8
Part, 2-6 parts of polycarboxylate water-reducer.
It preferably, in parts by weight include following component: 70 parts of water, 20 parts of sodium phosphate, industrial 2 parts of sucrose, triterpene
5 parts of saponin(e, 3 parts of polycarboxylate water-reducer.
Preferably, the sodium phosphate is dissociated into PO after being dissolved in water4 3-And Na+, a large amount of positive charge ion Na is provided+, should be from
Son has stronger adsorption capacity compared to other particles to suspend in water, and meeting Preferential adsorption is in flocculant (polyacrylamide
Amine) in molecule, so that it is adsorbed the reduced capability of other particles, to be shielded flocculating effect；PO4 3-It can be dissociated with cement
Ca2+Generate Ca not soluble in water3(PO4)2, it is deposited in cement particle surface, delays the heat evolution velocity of cement, promotes coagulation
The guarantor of soil is collapsed effect.
Preferably, the industrial sucrose is common concrete slump retaining agent, can delay the setting time of concrete.
Preferably, the triterpenoid saponin has bleed, and a large amount of equally distributed small gas can be introduced in concrete
Bubble, improves the workability of fresh concrete, improves the durability of concrete.
Preferably, the polycarboxylate water-reducer improves the workability of concrete, increases concrete flowability, improves pump
Send ability.
Compared to the prior art, the guarantor for improving concrete of the invention effect and easy agent of collapsing can shield flocculation
The flocculating effect of agent, be added in ordinary water-reducing agent about 1% and easy agent can promote the adaptability of water-reducing agent and cement,
The guarantor for improving concrete is collapsed effect.
Specific embodiment
Below in conjunction with embodiment, the invention will be further described.
The guarantor that the present invention provides a kind of for improving concrete is collapsed effect and easy agent, is wrapped in parts by weight
Include following component: 60-80 parts of water, 10-30 parts of sodium phosphate, industrial 1-5 parts of sucrose, 2-8 parts of triterpenoid saponin, polycarboxylate water-reducer
2-6 parts.
Embodiment one
It in parts by weight include following component: 70 parts of water, 20 parts of sodium phosphate, industrial 2 parts of sucrose, triterpenoid saponin 5
Part, 3 parts of polycarboxylate water-reducer.
The sodium phosphate is dissociated into PO after being dissolved in water4 3-And Na+, a large amount of positive charge ion Na is provided+, which compares
There is stronger adsorption capacity in other particles to suspend in water, meeting Preferential adsorption is in flocculant (polyacrylamide) molecule
In, so that it is adsorbed the reduced capability of other particles, to be shielded flocculating effect；PO4 3-The Ca that can be dissociated with cement2+It is raw
At Ca not soluble in water3(PO4)2, it is deposited in cement particle surface, delays the heat evolution velocity of cement, the guarantor for promoting concrete is collapsed
Effect.
The industry sucrose is common concrete slump retaining agent, can delay the setting time of concrete.
The triterpenoid saponin has bleed, and a large amount of equally distributed micro-bubbles can be introduced in concrete, improves new
The workability of mixed concrete improves the durability of concrete.
The polycarboxylate water-reducer improves the workability of concrete, increases concrete flowability, improves pumpability.
Some experimental data is as follows:
From test data as can be seen that being added with after easy agent, the flocculability of flocculant is shielded, when volume reaches
30g/m3When, two hours slumps of concrete are not in loss substantially.
Embodiment two
60 parts of water, 10 parts of sodium phosphate, industrial 1 part of sucrose, 8 parts of triterpenoid saponin, 6 parts of polycarboxylate water-reducer.
The practical application effect of the embodiment is (note: containing flocculant about 0.05% in sand after measured) as shown in the table
Embodiment three
80 parts of water, 30 parts of sodium phosphate, industrial 5 parts of sucrose, 2 parts of triterpenoid saponin, 2 parts of polycarboxylate water-reducer.
The practical application effect of the embodiment is (note: containing flocculant about 0.05% in sand after measured) as shown in the table
There are a pair of of lone pair electrons in polyacrylamide, on amido nitrogen, hydrogen bond can be formed with the hydrogen in water, adsorb water
Ability is larger, to increase the viscosity of water, in addition, the suspended particulate in water is mostly positively charged, can also be formed with amido nitrogen compared with
Strong absorption, the usual molecular weight of polyacrylamide is larger, and there are a large amount of amido, a large amount of solid particles are attracted to molecule knot
It is final to reunite with sinking on structure, make clarification of water.
The guarantor for improving concrete of the invention effect and easy agent of collapsing can shield the flocculating effect of flocculant, In
Be added in ordinary water-reducing agent about 1% and easy agent can promote the adaptability of water-reducing agent and cement, the guarantor for improving concrete is collapsed
Effect.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright description is applied directly or indirectly in other relevant technology necks
