62 Mixing agent for slip forming method JP3799394 1994-03-09 JPH07242455A 1995-09-19 YAMAKAWA TSUTOMU; SASAGE TAKEAKI; TOKUTANI NAOSHI
PURPOSE: To obtain a novel mixing agent for a slip forming method to improve the fluidity of concrete by incorporating welan gum and a swellable low- substitution hydroxypropylcellulose which does not completely dissolve in water. CONSTITUTION: (A) A low-substitution hydroxypropyl cellulose having <100μm grain size, in a single state or with a filler, is added to concrete. This cellulose is insoluble with water but swellable to adsorb bleeding water and to provide a bearing effect. If necessary, a mixing agent such as a dewatering agent and fluidizing agent is added. (B) Welan gum which is an extracellular gum produced by fermentation with Alcaligenes bacteria is refined by precipitation and recovery with alcohol. The obtd. gum is used as a mixing agent by ≤5.0kg/m 3 in a single state or with a water-reducing agent. Further, 5-100g nonion cellulose ether per 1m 3 and 50-2000g polyacrylamide per 1m 3 are compounded as a thickener to the mixing agent (A) to (B). COPYRIGHT: (C)1995,JPO

64 Production of fiber reinforced inorganic body JP26483491 1991-10-14 JPH05105497A 1993-04-27 TAKADA TAKASHI; HONDA YUZURU
PURPOSE:To obtain a fiber reinforced inorg. body ensuring excellent dimensional stability without curing at a high temp., having low specific gravity and also having excellent strength because reinforcing effect can be satisfactorily produced by short fibers. CONSTITUTION:A slurry contg. a hydraulic inorg. material contg. cement, a shrinkage inhibitor, short reinforcing fibers, water and a waterinsoluble vinyl monomer contg. a polymn. initiator and an emulsifying agent is prepd. and molded. The resulting molded body is hardened and cured to produce a fiber reinforced inorg. body.

PURPOSE:To provide an acrylic fiber-reinforced inorganic form high in mechani cal strength and excellent in dimensional stability, capable of trimming the equipment cost for its molding and running cost. CONSTITUTION:Firstly, an emulsion is prepared by incorporating (A) 100 pts.wt. of a hydraulic material comprising (1) 30-75wt.% of cement and (2) 70-25wt.% of pozzolanic active silica with the molar ratio Ca0/SiO2 coming to 0.5-1.2 with (B) 0.4-40 pts.wt. of acrylic short fibers 1-15mm in mean length, (C) 20-500 pts.wt. of water, and (D) 1-150 pts.wt. of a waterinsoluble vinyl monomer containing (1) 0.5-5wt.% of a polymerization initiator and (2) 3-50wt.% of an emulsifier. Then this emulsion is extruded into a forming which is, in turn, put to autoclave curing at 100-180 deg.C for 3-15hr.
66 Redispersible powder of vinyl polymer JP35292391 1991-12-17 JPH04335050A 1992-11-24 JIYANFURANSOWA KORONBE; BURUNOO TEIBOO
PURPOSE: To provide water-redispersible pulverulent compsn. based on a water- insoluble vinyl and/or acrylic polymer and to disclose uses of the powders in the construction industry. CONSTITUTION: Water-redispersible powders of a water-insoluble film-forming vinyl and/or acrylic polymer are obtd. by incorporating at least one silicone and these powders are made as adjuvants for mixtures for hydraulic binders used in the construction industry.

67 METHODS AND MATERIALS FOR ZONAL ISOLATION PCT/GB2006002351 2006-06-26 WO2007003885A3 2007-05-03 SAWDON CHRISTOPHER ALAN; LADVA HEMANT KUMAR JETHALAL; JONES TIMOTHY GARETH JOHN; TUSTIN GARY JOHN
The invention relates to the use of one or more water-soluble reactive liquid component capable of subsequent polymerization or cross-linking to form a solid to improve the zonal isolation and alleviate the impacts of cracks and fissures in the cement sheath around a completed subterranean well. It includes the steps of injecting a wellbore fluid carrying the reactive component or additive into the wellbore, injecting a cementitious composition as slurry into the wellbore and letting said reactive liquid component pass through at least one of the interfaces between cement and formation, cement and filter cake, and filter cake and formation before forming a solid of said reactive liquid component that traverses said at least one of the interfaces.
68 NOVEL HYDRODISPERSIBLE WATERPROOFING AGENT, THE PREPARATION THEREOF, AND THE USE OF THE SAME IN THE FIELD OF CONSTRUCTION ESPECIALLY IN MINERAL BINDING AGENT COMPOSITIONS PCT/FR2005001281 2005-05-24 WO2005118683A3 2006-07-20 MERCIER JEAN-MICHEL; JOUBERT DANIEL; TAQUET PASCAL; DERUELLE MARTIAL
The invention relates to a novel hydrodispersible waterproofing agent based on at least one water-insoluble and water-immiscible waterproofing agent which has previously been emulsified in a hydrosoluble amphiphilic copolymer composition. The invention also relates to the solid forms of said composition obtained by drying, and to the use thereof in a water-insoluble film-forming polymer composition or in a mineral binding agent composition for applications in the field of construction.
69 METHOD FOR SEALING NATURAL STONES PCT/EP2005052507 2005-06-01 WO2006010663A3 2006-04-06 NUN EDWIN; HENNIGE VOLKER; PAULMANN UWE; ARMONEIT HANNELORE; BANKEN SIGRID; WILKES MARIE-THERES; KERN NORBERT; HERKT-BRUNS CHRISTIAN; SCHRIEF THOMAS; BERENDES ECKART
The invention relates to a sealed natural stone. The pores thereof are permeable to steam but impermeable to aqueous liquids. The invention also relates to a method for the production and use of said type of natural stone.
