Abstract: An adhesive composition, includes at least one vegetable starch the amylose content of which is between 30 and 60%. The invention further relates to the method for using the composition, including application thereof to lignocellulose materials, the forming of a panel and the hot pressing thereof. The emissions of formaldehyde vapor during the method are as low as possible. The invention further relates to the panels produced as above and in particular the panels emitting reduced amounts of formaldehyde into the atmosphere.

Abstract: The invention concerns a powdered or granular composition, useful for preparing non-food and non-pharmaceutical products, characterized in that it contains at least one legume starch, and at least one additive selected from a flow agent, a filler, a polymer, an active principle or a mixture thereof. The invention also concerns the use of such a composition in the non-food and non-pharmaceutical fields.

Abstract: an industrial fluid includes a selected legume starch with a Brookfield viscosity of between 100 and 20 000 mPa.s, as component of the industrial fluid. The legume starch preferably also has a solubility in water of between 10 and 85%. The industrial fluid is particularly a fluid for use in boreholes with a pH greater than 8.5 and which can be used at a temperature above 130° C. The invention further relates to a method for preparation of a legume starch, selected thus by the viscosity thereof and also several families of novel legume starches, characterized by particular ranges of viscosity and aqueous solubility.

Abstract: The subject matter of the invention is a new additive for mineral binders comprising a composition containing at least one product of internal dehydration of a hydrogenated sugar which can especially be a dehydrated hexitol such as isosorbide, isomannide, sorbitan or mannitan and which can be introduced at a rate of between roughly 0.001 and 5% (dry/dry) within any mineral binder, said additive being advantageously used as an accelerator for setting and/or hardening and/or as an agent for improving the mechanical properties of the mineral binder. It has a remarkable efficiency, including at low temperatures.

Abstract: A novel admixture for mineral binders is composed of a polyol composition with a high hydrogenated disaccharide content (≧40%). The hydrogenated disaccharide is advantageously chosen from maltitol, lactitol and mixtures thereof. Within the admixture, the polyol composition (for example, maltitol powder, a maltitol syrup or a hydrogenated starch hydrolysate) may be combined with conventional admixtures for mineral binders, particularly lignosulfonates. The hydrogenated disaccharides make it possible to obtain an excellent compromise between retardation, plasticity and the mechanical properties of the mineral binder. They may be used equally well for admixing with cements and raw materials for cements as for admixing with mortars, slurries and concretes.

Abstract: Process for the preparation of a water-resistant fuel agglomerate, characterized by the fact:that there are employed a finely divided fuel material, an organic binder and an oxidizing agent,that the oxidizing agent is mixed with either the fuel material, or the organic binder, or with one or other of these products or their mixture,that the mixture so obtained is subjected to an agglomeration treatment, andthat the agglomerate obtained at the end of the agglomeration treatment is subjected to a stoving treatment.

Abstract: A water-resistant fuel agglomerate based on finely divided fuel material, is characterized by the fact that it comprises, distributed within its constituent mass, effective proportions respectively of at least one organic binder selected from the group comprising starches, starch derivatives, flours, proteins, celluloses, hemicelluloses as well as the mixture of these substances, and of at least one organosilicic waterproofing or water-repelling agent.
