Definitions
- 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.
- 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.
- “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
- “molasses fermentation byproducts” contain too many variables. Therefore these byproducts are seldom used in concrete admixtures application.
- 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.
- the main disadvantage of this method is that molasses is not used as a surfactant- dispersant.
- Molasses in the series is treated in acid and alkali environments at temperatures higher than ambient.
- Inorganic and organic acids can be used for acidification of molasses up to pH 0.8
- Inorganic and organic alkalis can be used for alkalization of molasses up to pH14.0
- Temperature of acid and alkali treatment can be 50-200°C at ambient, positive and negative pressure
- Catalysts of acid and alkali hydrolysis (oxidation) can be used for the treatment
- Solids content of molasses can be 5.0-90.0%
- 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
- 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
- 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].
- 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.
- the modified molasses was tested as a plasicizer in cement mortars in comparison with the best general European softwood Na and Ca lignosulphonates.
- 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.
- NA and CA Lignosulphonates are typical middle range water reducers and retarders.
- Compressive strength of all cement mortars with the molasses modifications is a slightly higher in comparison with the mortars with lignosulphonates.
- 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.
