Abstract

A method of treating molasses in which the molasses is modified to yield surfactants with plasticizer (water reducing) and dispersant properties. The essence of the treatment is that the molasses in the series is treated in acid and alkali environments at temperatures higher than ambient. This means that the ingredients of molasses are exposed to acid and alkali hydrolysis. The acid treatment provides the production of monosaccharides (reducing sugars), aldonic and aminocarbonic acids. The alkali treatment provides the forming of saccharinic acids and their salts, aldonic acid salts, aminocarbonic acids and their salts, and soluble soaps of wax ethers. The molasses modifications can be effectively used for concrete plasticizers (water reducing admixtures) and cement clinker grinding additives application.

Description

Application for Invention
Title: Molasses treatment for the "Molassperse" surfactant production for concrete plasticizers (water reducing admixtures) and cement clinker grinding additives application
1. Background
1.1. Concrete admixtures
Molasses (see molasses typical analysis in Appendix 1) is traditionally used as a retarding agent in concrete admixtures [1,4]. It allows increased settings and as a result slightly reducing water consumption in concrete mixes.
Chinese patent titled: "PROCESS FOR PREPARING SETTING RETARDANT TYPE-HIGH- EARLY STRENGTH WATER-REDUCING AGENT AND PRODUCTS THEREOF" [2] is close to our presented invention.
This invented setting-retardant type high-early strength water reducing agent is prepared as follows: after molasses is diluted to 1.22-1.25 Baum'e degrees and heated to 70-80 deg.C, lime of 1-2 wt. % of that of diluted molasses is added for reaction to make a portion of sugar react with calcium oxide to form soluble calcium sugar which can produce optimum effect of water reduction. The result is that the product after reaction still retains a portion of sugar component so that the said product not only possesses the effect of water reduction, but also that of setting retarding, meanwhile, the addition of anhydrous sodium sulphate in a certain proportion makes it have the effect of high-early strength.
It is known that sugar (molasses sugar) added to the concrete mix immediately react with calcium oxide (which is produced in the process of cement hydration) and form "soluble calcium sugar".
The difference of this Chinese method, in comparison with traditional molasses using (direct molasses addition in concrete mix), is that a relatively small part molasses sugar is converted to "calcium sugar". The disadvantages in this method are: from a position of molasses modification: practically nothing is changed in the ingredients of concrete mix; just the process of formation of a small quantity of "calcium sugar" is slightly intensified "calcium sugar" starts to precipitate [3] at temperature lower than 20 deg. C misbalancing the hardening of concrete - sodium sulfate is used for reduction of traditionally strong molasses sugar retardation effect
The closest to the presented invention is the traditional Soviet Union's method [4] which is covered by Korean patent [5] titled: CONCRETE ADMIXTURES CONTAINING MOLASSES FERMENTATION BYPRODUCTS.
"Molasses fermentation byproducts" essentially are spent waste liquor after fermentation of molasses sugars and extraction of fermentation products (mainly alcohol and yeast) from the "mother liquor". This molasses spent waste liquor in comparison with original molasses contains a relatively small quantity of the byproducts from the sugar fermentation process mainly in the form of different organic acids. These acids slightly increase the surfactant properties of molasses spent waste liquor in comparison with original molasses. The main disadvantage (problem) of the "molasses fermentation byproducts" (molasses spent waste liquor) is their still lower surfactant properties in comparison with traditional water reducing agents such as lignosulphonates. Also "molasses fermentation byproducts" contain too many variables. Therefore these byproducts are seldom used in concrete admixtures application.
1.2. Cement clinker grinding additives
Traditionally molasses is not used as a grinding additive because of its low dispersant properties (low properties surfactant). However Chinese patent [6] titled: METHOD FOR
USING TALC & MOLASSES AS CEMENT GRINDIG AID suggests to use molasses for this application in combination with talc in approximate proportion, accordingly, 1 :10.
It seems that in this composition molasses is used as a well known adhesive agent.
In the process of grinding, talc is a much softer material than cement clinker and gets ground significantly thinner than clinker. The very fine particles of talc in the complex with molasses (as adhesive agent) hypothetically can envelope cement particles averting them from (against) aggregation.
This method is not widely used because of its low effectiveness.
The main disadvantage of this method is that molasses is not used as a surfactant- dispersant.
2. Idea of the Suggested Molasses Treatment
Deep modification of the molasses ingredients, converting them to the effective surfactants with plasticizer (water reducing) and dispersant properties.
3. Description of the Treatment (Invention)
3.1. Essence of the treatment
Molasses in the series is treated in acid and alkali environments at temperatures higher than ambient.
This means the ingredients of molasses are exposed to acid and alkali hydrolysis.
3.2. Regimes and parameters of the treatment

3.2.6. Time of the treatment: - acid treatment 10min-24 hours alkali treatment 10min-24 hours 3.2.7. After both the acid and alkali treatment, the pH of molasses can be adjusted to the required levels.
4. Treatment effect on molasses properties
4.1. Acid treatment provides: - converting of polysaccharides to monosaccharides (reducing sugars) converting of the part of monosaccharides to aldonic acids - decomposition of proteins to aminocarbonic acids with a relatively high quantity of carboxyl and amino groups
4.2. Alkali treatment provides: - converting of monosaccharides (reducing sugars) to saccharinic acids and their salts converting of aldonic acids to their salts decomposition of the residuary proteins to aminocarbonic acids - converting of aminocarbonic acids to their salts - converting (saponification) of wax ethers to the soluble soaps
5. Properties of the new formations of the treated molasses
5.1. The salts of saccharinic and aldonic acids are quite strong anionic surfactants with high dispersion properties.
The salts of aminocarbonic acids and wax soaps are effective wetting agents and detergents [7].
5.2. Content of the produced complex of the surfactants: - domination of saccharinic and aldonic acids salts - a small part of aminocarbonic acids salts and wax soaps
5.3. The produced complex of the surfactants provides a relatively high effectiveness of the treated molasses as concrete plasticizers (water reducing admixtures) and clinker grinding additives.
6. Application tests of the treated molasses
6.1. The modified molasses was tested as a plasicizer in cement mortars in comparison with the best general European softwood Na and Ca lignosulphonates.
The test results are shown in Appendix 2.
6.2. The modified molasses was also tested as a clinker grinding additive. The test results are shown in Appendix 3.

Investigations of "Molassperse" Modified Molasses for Concrete Applications
Modifications
Three modifications of the raw molasses were done in the AIA laboratory.
The modifications were named Molassperse P-l, Molassperse P-2 and Molassperse P-3.
Testing in cement mortars
The best general European softwood Na and Ca lignosulphonates were used as control samples.
Consumption of the molasses modifications and lignosulphonates were 0.1, 0.2 and 0.3% of cement mass.
Blue Circle Southern Cement was used for making the cement mortars.
Two river sands (coarse and fine) were used in the tests (ratio 1:1).
Water/Cement ratio for all cement mortars was constant - 0.55.
Ratio Cement : Sand : Water was 1 : 3 : 0.55.
Fluidity of cement mortars was determined with Flow Table.
Air entrainment was determined by a volumetric method.
Cement mortar ISO prisms 40x40x160mm were made for compressive strength determination.
The results of the tests have shown in Table 1.
Discussion
NA and CA Lignosulphonates (control) are typical middle range water reducers and retarders.
Cement mortars with Molassperse P-l, Molassperse P-2 and Molassperse P-3 in comparison with NA Lignosulphonate and CA Lignosulphonate have a higher fluidity at low consumption 0.1 %.
At the middle consumption 0,2% and high consumption 0.3%- the mortar fluidity is similar for the molasses modifications and lignosulphonates.
Compressive strength of all cement mortars with the molasses modifications is a slightly higher in comparison with the mortars with lignosulphonates.
This can be explained by a higher air entrainment of lignosulphonates. Conclusions The molasses modifications are compatible with the best general European softwood Na and Ca lignosulphonates The molasses modifications can be characterized as middle range water reducers with a low air entrainment.
