Abstract
The invention relates to a method for preparing a concrete admixture by using vinasse prepared by distilling sugarcane molasses, which is different from the Chinese patents No.36.110 applied on January 4th 1997. At the initiation phase in the method for preparing the concrete admixture by using the vinasse prepared by distilling the sugarcane molasses, powders are not used, but the vinasse before being subject to condensation is used, a liquid product is obtained finally. The improved method for preparing the concrete admixture by using the vinasse prepared by distilling the sugarcane molasses comprises the following steps: collecting specifically-quantitative sugarcane vinasse with 8-10% of an undissolved substance; carrying out condensation on the sugarcane vinasse in two steps so as to cause the sugarcane vinasse to reach 60 degrees in degrees brix at temperature of 60 DEG C, and mixing with formaldehyde and soda ash in a trough; and decanting the mixture into the other trough with three outlet heights, wherein the outlets can be used for obtaining a product of which an undissolved substance is less than 1%. The product can change structural characteristics of the concrete, and can improve the plasticity of the concrete and the static dispersion of cement in the concrete mixture.
Description
Technical field
The present invention relates to the concrete admixture preparation method's that a kind of building industry used especially in concrete mix improvement, this admixture makes with the vinasse that cane molasses distillation produces.
Background technology
Building industry is used different mixtures to improve concrete performance according to various purposes.
While preparing concrete according to special purpose, with the special modified product that cane molasses distillation obtains, improve and adjust some characteristic particularly important.For example, if need more increase resistance, must reduce water cement ratio with liquid agent.These products for every kind of specific function are known as concrete admixture.Modal concrete admixture is that those improve the liquid agent of fresh concrete usability by changing concrete surface tension force.They also reduce intergranular friction, and make cement granules with static charge, and cement granules is repelled mutually, thereby avoid agglomerating, and therefore improve concrete quality.Use liquid agent can also reduce concrete water-content, gain in strength, provide better concrete quality, and because it has replaced a part of cement in concrete mix, so more cheap, these are all known.
The important character of another one of admixture is that it allows the more mobile mixture of preparation, and eliminates air content.
Admixture of the present invention can be used according to concrete desired use together with other concrete hardenerss, promotor or slow setting composition.For example, if this concrete must transport at a distance, must postpone to condense the time opening.On the contrary, if concrete, for the manufacture of pre-manufactured product, can shorten time of coagulation.
Summary of the invention
The present invention relates to a kind of vinasse that obtained by sugarcane distillation and prepare the novel method of concrete admixture.
The admixture making is by the concrete preparation for building industry.
As previously mentioned, this technique is usingd the product that is known as vinasse that cane molasses distillation obtains as initial.
For removing the calcium sulfate insolubles that may stop up dosage valve in final product, vinasse are disperseed under the action of the centrifugal and remove described insolubles.The vinasse concentration that does not contain insolubles of this distillation is between 8 ° of-10 ° of Brixs (Brix).
For reducing fermentation capacity and water-content, be beneficial to carry, vinasse are delivered to plate-type condenser.Vinasse enter this thickener, and make its Brix bring up to 45 ° from 8 ° in the first stage; In the second thickener and subordinate phase, make the Brix of vinasse be increased to 60 °.The product of condensation is discharged the temperature of 66 ℃, and keep this temperature that described product is sent in tempering tank, in tempering tank, added formaldehyde and sodium hydroxide (SODA ASH LIGHT 99.2).It is sent into decanting tank from this groove, and this decanting tank has three outlets at various height, is used in each outlet test by the insolubles percentage after concentrated.At this temperature, reduced viscosity is to certain value, and insolubles is precipitated to container bottom very soon.
During due to condensation, water is removed, and insolubles is also removed and has reached minimum percentage with the form of calcium sulfate, between 0-1%, thereby provides the fermentation capacity reducing above-mentioned treatment stage.
Concentrated vinasse product is a kind of water reducer, and not with cement or any other cement component generation chemical reaction, its effect just changes the physical properties of cement, particularly for the physical properties of the tensile surface of cement.As tension active agent composition, it has the hydrophobic free base being formed by propyl group cloves (propilsyringilic) class phenyl, the repulsion that it is positioned at one end of molecule and is subject to water.At the other end of molecule, it comprises a hydrophilic free radical being formed by water acceptor sulfate.These compound effects are on cement granules, make it more easily infiltrate, flow, slide, and become the mixture that has more mobility, simultaneously, better water absorbability is provided and has flowed to be penetrated into the performance in the cement of sclerosis, to obtain the denseness of expectation in the situation that reducing water cement ratio.
For obtaining this concrete admixture, vinasse enriched material adopts encapsulant (blocking agent), stablizer and for example terpin calcium (calcium terpenate) and the product of sodium hydroxide to process.Terpin calcium produce as have 2-4 micron diameter bubble contain air.Yet, its not remarkably influenced concrete resistance.And the heat that the thermopositive reaction of water-cement produces has improved the mobility of mixture.Sodium hydroxide is increased to 7.5 by the pH value of product, has avoided the fermentation of product.These compositions have changed the acidity of product, make it become water reducer fluidisation admixture.
Accompanying drawing explanation: Fig. 1 is process flow sheet of the present invention
Embodiment
Final product provides the improvement of the patented method that focuses on fine concrete admixture, and the vinasse that this admixture is obtained by cane molasses distillation make, and more specifically, the vinasse enriched material being obtained by the method by following steps as shown in the schema of Fig. 1 is made:
The first step: the vinasse that preparation comprises the solid between 8 ° of-10 ° of per-cents of Brix.
Second step: vinasse are sent into the thickener I with plate-type condenser, in the first stage, the Brix of vinasse is increased to 45 ° by 8 °-10 °.
The 3rd step: the vinasse that second step is obtained are sent into plate-condenser thickener II, is increased to 60 ° by the Brix of described product by 45 ° in subordinate phase.
The 4th step: the enriched product with low viscosity and 66 ℃ of temperature is taken out, and keep this temperature, sent into tempering tank, add formaldehyde and sodium hydroxide (SODA ASH LIGHT 99.2) in tempering tank.
The 5th step: mix products is transported in decanting tank, and this decanting tank has three (3) the individual different open heights (I, II and III) that go out, and it allows to detect insolubles percentage.At the temperature of 66 ℃, reduced viscosity is to certain value, and insolubles is deposited to container bottom, and because insolubles is precipitated to container bottom, so this situation allows product to discharge from going out open height I, II and III.
