USE OF A CEMENTITIOUS COMPOSITION AS A COATING FOR DISPOSABLE FOUNDRY CORES AND RELATIVE COATED CORE
Publication number: 20190262894Abstract: The use of a cementitious composition is described, as a coating for disposable foundry cores, said cementitious composition comprising at least one binder or hydraulic cement in a quantity ranging from 40% to 99.9% by weight with respect to the total weight of the cementitious composition; possibly one or more fillers in a quantity ranging from 0.1% to 60% by weight, with respect to the total weight of the cementitious composition, said filler preferably having a D99<100 ?m; at least one rheology modifying agent selected from cellulose, derivatives of cellulose such as methylhydroxyethylcellulose, vinyl acetate/versatate copolymers, polycarboxylate ether polymer, or a mixture thereof, in a quantity ranging from 0.1% to 5% by weight with respect to the total weight of the cementitious composition. A disposable foundry core is also described, having at least one coating layer based on said cementitious composition.Type: ApplicationFiled: June 8, 2017Publication date: August 29, 2019Applicant: ITALCEMENTI S.p.A.Inventors: Roberto CUCITORE, Maurizio Iler MARCHI, Gianluca LEZZI, Marco ORLANDO -
Patent number: 8039100Abstract: The present invention concerns a composite cement paving with photocatalytic action for reducing urban polluting agents, composed of a bituminous or cement foundation, a resin having the function of interface, a superficial cement layer with photocatalytic properties able to reduce organic and inorganic polluting agents, said paving also comprising reinforcing materials and possible suitably positioned fibrous materials. The paving thus realised presents a strong photocatalytic action, prolonged overtime, even in the presence of high mechanical stress caused by heavy traffic.Type: GrantFiled: June 22, 2005Date of Patent: October 18, 2011Assignee: ITALCEMENTI S.p.A.Inventors: Roberto Cucitore, Stefano Cangiano, Luigi Cassar

Patent number: 7678191Abstract: Described herein are new cementitious mortars with a high degree of fluidity and short consolidation times. The mortars contain water, a fast-setting cement, fluidifiers and/or superfluidifiers, setting regulators and aggregates having a specific granulometric distribution. The aggregates are made up of two fractions with different grain size such that the ratio between the characteristic grain diameters of the two fractions is comprised between 2.2 and 3.2. The new mortars thus obtained have values of fluidity 2-3 times higher than those of mortars produced with traditional aggregates; the increase in fluidity is obtained without increasing the water/cement ratio and without increasing the amount of fluidifiers present. The mortars produced according to the invention may be used to advantage in all applications in which it is required to associate a high degree of fluidity and a rapid consolidation.Type: GrantFiled: February 10, 2005Date of Patent: March 16, 2010Assignee: Italcementi S.p.A.Inventors: Umberto Costa, Roberto Cucitore

Patent number: 7641732Abstract: Described herein is the use of new cementitious mortars with a high degree of fluidity and short consolidation times in the production of cementitious products by means of pouring in foundry moulds. The mortars used contain water, a fast-setting cement, fluidifiers and/or superfluidifiers, setting regulators, and aggregates having a specific granulometric distribution. The aggregates are made up of two fractions with different grain size such that the ratio between the characteristic grain diameters of the two fractions is comprised between 2.2 and 3.2. The new mortars thus obtained have values of fluidity 2-3 times higher than those of mortars produced with traditional aggregates.Type: GrantFiled: February 8, 2005Date of Patent: January 5, 2010Assignee: Italcementi S.p.A.Inventors: Umberto Costa, Roberto Cucitore

Patent number: 7628852Abstract: Described herein are new cementitious mortars with a high degree of fluidity and high final resistance. The mortars contain water, a hydraulic binder, a pozzolanic substance (finely ground slag), a fluidifier and/or superfluidifier, a setting regulator, and aggregates having a specific granulometric distribution. The aggregates are made up of three highly monogranular fractions (A, B, C), and a fourth fraction (D) having a low monogranularity. The new mortars described herein have values of fluidity higher, by approximately 70%, than those of mortars produced with traditional aggregates. The increase in fluidity is obtained without increasing the water/cement ratio and without increasing the amount of fluidifiers/superfluidifiers present. The mortars produced according to the invention may be used to advantage in all applications in which it is required to associate a high degree of fluidity and a high final mechanical resistance, both in compression and in flexure.Type: GrantFiled: February 9, 2005Date of Patent: December 8, 2009Assignee: Italcementi S.p.A.Inventors: Umberto Costa, Roberto Cucitore
