Abstract:
The present invention is in the field of admixtures to be used e.g. in concrete or mortar in order to improve characteristics of a final product, a method to obtain such an admixture, a product, typically being a solid product, such as concrete, mortar, glass, and cement, comprising said admixture and use of said admixture. The admixture comprises: a silica alumina compound, such as metakaolin or by-products of thermal conversion of paper waste and residue from the paper production, a calcium compound such as calcium carbonate, calcium hydroxide and a modifier, such as a surfactant, an emulsifier or a dispersant.
Abstract:
Dry mortar mixture characterized by a glass mixture of expanded glass beads with a grain size d/D 0/8, mixed in a ratio of between 1:1 and 1:3, for example 1:2 with a dust poor or dust free binding mixture of hydraulic binders and stone granules in the weight ratio of 1:2 to 1:4. The glass has a discontinuous grain distribution. For the glass mixture the fractions 0,5/1,0 and 2,0/4,0 are present while the fractions 0.25/0.5 and 1.0/2.0 are absent. For the glass mixture preferably all grain sizes between 1.0 and 2.0 mm are absent and the grain size distribution is around an average, so that an open structure is obtained.
Abstract:
The invention relates to a dry mixture of embedding material or moulding material for producing embedding or moulding material for a metal casting method, such as the lost-wax method, said mixture containing a hydraulic binding constituent. Said binding constituent contains, as a hydraulic binding agent, ground Portland cement clinker which is free of sulfate carriers.
Abstract:
Die Erfindung betrifft eine Einbettungs- bzw. Formmassentrockenmischung zur Herstellung von Einbettungs- bzw. Formmassen für Metallgießverfahren wie das Wachsausschmelzverfahren, aufweisend eine hydraulische Bindemittelkomponente, wobei die Bindemittelkomponente als hydraulisches Bindemittel sulffatträgerfrei vermahlenes Portlandklinkermehl enthält.
Abstract:
Die Erfindung betrifft ein Polykondensationsprodukt auf Basis von Aromaten und/oder Heteroaromaten und Aldehyden, wobei es mindestens eine eine Polyisobutylenseitenkette und einen Aromaten oder Heteroaromaten aufweisende Struktureinheit (I) sowie mindestens eine eine ionisierbare, funktionelle Gruppe und einen Aromaten oder Heteroaromaten aufweisende Struktureinheit (II) enthält, wobei Struktureinheit (I) ungleich Struktureinheit (II) ist und der eingesetzte Aldehyd keine Säure oder Esterfunktionen aufweist. Es wird ein Verfahren zur Herstellung sowie die Verwendung als Additiv für hydraulische Bindemittel offenbart.
Abstract:
A dry formulation for an integrated marking material for concrete and asphalt application comprises a cementitious mixture including a hydraulic or cementitious binder, a redispersible polymeric cement modifier, a retroreflective agent filler, and optionally, a reflective agent filler. The formulation preferably includes a pigment, aggregate, a dispersant, a plasticizer, and/or a water reducer. The formulation optionally includes at least one admixture selected from an accelerator, an air entrainer, a defoamer, fibers, an inert filler, a natural clay, a pozzolanic filler, a retarder, a rheology modifier, a shrinkage compensating agent, a synthetic clay, a suspending agent, and a thickening agent. The marking material, when applied, has broadcast onto and embedded into its surface, additional retroreflective agents.
