Definitions

  • the present invention generally concerns a concentrated sugar additive comprising (a) raffinate derived from citric acid recovery industry and (b) a sugar- containing solution useful for delay setting time of cement preparations, such as cement paste, mortar, concrete, etc.
  • Portland cement is mainly composed by clinker, pozzolan and gypsum and acts as an active hydraulic binder that sets when mixed with water by way of a complex series of chemical reactions. The different constituents slowly crystallize and the interlocking of their crystals provides strength. Portland cement not only hardens by reacting with water but also forms a water-resistant final product. For this reason, it has been largely used for building as basic ingredient of cement preparations, e.g. concrete, mortar or cement paste.
  • Additives have been included in the cement preparations in order to modify the properties of final product and obtain higher quality, low-cost and efficient production .
  • Set retarder additives are useful to delay hydration of cement by forming a film around the cement compounds (e.g., by absorption), thereby preventing or slowing the reaction with water. The thickness of this film will dictate how much the rate of hydration is retarded. After a while, this film breaks down, and normal hydration proceeds.
  • Gypsum and calcium chloride are used to attempt regulation of setting time of such preparations.
  • Other agents are specifically applied as additives for stopping fresh concrete from quickly drying out, providing reinforced products without cracking.
  • such additives are specific inorganic compounds or complex mixtures (e.g. the additives disclosed in US1859253; US3695906, US5925416, US5573588, WO9940041, and US5993531) .
  • the additive according to the present invention comprises (a) raffinate and (b) a sugar-containing solution .
  • Raffinate (a) is an aqueous solution effluent (for instance syrup or liquor) from fermentation processes (residuary or not) .
  • Raffinate (a) is an aqueous solution comprising at least citric acid, inorganic matter (such as minerals) , proteic matter and sugar matter.
  • sugar matter typically includes carbohydrate selected from fructose, dextrose, maltose and/or polyol selected from arabitol, erythritol, or mixtures thereof.
  • the inorganic matter is measured by analyzing ashes and typically includes nitrogen, phosphorus, potassium, calcium, magnesium, sulphur, iron, manganese, copper, zinc, boron, sodium or mixtures thereof.
  • raffinate (a) may be a by-product derived from the citric acid recovery process, for instance as disclosed in the patent US 4,994,609, assigned to Cargill Inc. (1991), incorporated herein as reference.
  • the raffinate (a) ingredients ratio depends on the performance of the recovery industry. In this case, a by-product without commercial application is used as raw material to the manufacture of a commercial product, also avoiding cost with waste treatment.
  • the sugar-containing solution (b) may be obtained from several sources, for instance corn, sugar cane, cassava, potato, wheat, rice, etc.
  • a solution may be syrup, i.e. a viscous liquid with a sugar content.
  • Such a component also includes enzymatic or acid conversion syrup, independently from the conversion grade.
  • Sugar is selected from carbohydrates or saccharides in general, including monosaccharides, disaccharides , oligosaccharides, polysaccharides, or mixture thereof.
  • the solution (b) comprises monosaccharide such as glucose (dextrose), fructose (levulose), galactose, xylose or ribose; disaccharides such as sucrose, maltose or lactose; oligosaccharides such as raffinose or stachyose; polysaccharides such as or starch, amylose, amylopectin, cellulose, chitin; hydrolysates (for instance inverted sugar), derivatives or mixtures thereof.
  • monosaccharide such as glucose (dextrose), fructose (levulose), galactose, xylose or ribose
  • disaccharides such as sucrose, maltose or lactose
  • oligosaccharides such as raffino
  • the sugar- containing solution (b) may be a viscous concentrated solution of sugar, in water or other liquids (for instance alcohols) .
  • a solution may also include other ingredients such as coloring agents, flavors or thickening agents .
  • component (b) contains about 40% equivalent dextrose in relation to about 80% total solids.
  • dextrose for instance, such an ingredient is commercialized as Glucogill 40/82 by the Cargill group in Brazil .
  • the concentrated sugar additive useful as set retarder comprises:
  • the present invention also concerns a process for manufacturing a set retarder comprising the following steps of:
  • the resulting set retarder according to the present invention presents % Brix (sugar parameter) from about 70 to about 75.
  • the % Brix is analyzed by a refractometer .
  • the viscosity is measured by cooling the sample at 25 °C and 20 rpm in a Brookfield viscometer DV I.
  • the additive according to the present invention Due to the characteristics of the additive according to the present invention, especially with respect to controlled concentrations of sugar, as well as physical characteristics, it is possible to obtain an improved additive able to delay hydration of cement, i.e. for delay setting time of any kind of cement preparation, such as concrete, mortar, cement paste, etc.
  • the concentrated sugar additive according to the present invention may also comprise other ingredients well known in the art, such as surfactants, biocides, pH adjusters, thickeners, etc.
  • the present invention also concerns the use of the additive as described above as set retarder for cement preparations, as well as a method for setting the time of such preparations that comprise applying an acceptable amount of an additive as described above.
  • This method is particularly useful for producing cement preparations having improved characteristics, e.g. plasticity, hardening, non-cracking and non-shrinkage.
  • a raffinate sample was obtained from the citric acid recovery process disclosed in the patent US 4,994,609, assigned to Cargill Inc. (1991).
  • the analyzed sample also contains solids (15%) and trace ingredients ( ⁇ 100ppm) .
  • a sample of the set retarder was prepared by:
  • step (b) mixing 6 kg of the raffinate obtained in the step (a) with 4 kg of a glucose syrup, commercialized as Glucogill 40/82, until complete homogenization.
  • the result shows that the set retarder according to the present invention presents improved performance when comparing a set time.
  • the set retarder according to the present invention has a 60-minute time to delay the cement set compared to the cement without such a retarder.
  • Figure 1 shows that one obtained a better passage of the liquor by perlimax with the amount of 0.01% enzyme in the first and second tests. It was noted that with 0.04%, the passage through perlimax was less effective than the liquor without enzyme.
