Abstract:
The present invention relates to a non-shrink high viscosity chemical grout composition, more particularly to a non-shrink high viscosity chemical grout composition comprising, on the basis of solid content, a) 100 parts by weight of a room temperature curable organic liquid phase resin; b) 10 to 200 parts by weight of glass beads; and c) 10 to 500 parts by weight of glass powder. In addition, the present invention relates to a method for repairing and reinforcing a construction using the non-shrink high viscosity chemical grout composition. The non-shrink high viscosity chemical grout composition of the present invention has superior acid resistance, alkali resistance, injection property, fluidity, crack resistance, impact resistance, adhesion property and storage property, and the method for repairing and reinforcing a construction of the present invention has affinity with subsidiary materials, can completely restore function and shape of a construction in short time due to rapid curing and simple construction, compensates properties of construction such as tensile strength, allows strong adhesion to a construction, and prolongs lifetime of a construction.
Abstract:
The invention concerns a method for inerting clays in sand intended for preparing hydraulic compositions, comprising a step which consists in adding to the composition or one of its constituents a cationic polymer having a cationic charge density more than 0.5 meq/g and an intrinsic viscosity less than 1 dg/l.
Abstract:
The invention is a composition of an architectural papier-mâché, and articles made therewith. Articles formed from using the architectural papier-mâché have excellent weather resistance, and can be used outdoors, as well as indoors. The composition is comprised of cellulose insulation and a joint compound. Cellulose insulation is a paper-based material, like newsprint or phonebook paper that is shredded and chemically treated with boric acid, which imparts resistance to mold, mildew, fungus, insects, moisture and flammable combustion.
Abstract:
Provided are methods and systems for introducing a wet gypsum accelerator or other high viscosity production additive to an aqueous dispersion of calcined gypsum in a discharge apparatus downstream of a stucco mixer in which the dispersion was prepared. These methods and systems are useful in the production of various gypsum products such as board including wallboard and ceiling tiles.
Abstract:
A photoluminescent material is formed by curing a blend of a transparent base material and a photoluminescent pigment component, wherein the viscosity of the transparent base material is 1 Pa·s(20° C.) or more and is added in an amount of 7 to 95 wt %. Luminescence performance is further improved by taking in consideration the relation between the internal structure of a molding and its luminescence performance, thereby achieving a luminescence of predetermined brightness for an extended period of time.
Abstract:
Compositions for controlling wellbore fluid and gas invasion including methods for using the compositions. The compositions are initially flowable slurries preferably comprising about 70 to 30% by weight of magnesium oxychloride and about 70 to 30% by weight of water. The compositions undergo a rapid phase transition to form a substantially solid mass with a near-linear relationship between the time required for the phase transition to occur and the composition temperature at which the phase transition occurs thereby permitting accurate determination of the set time. The method includes use of the composition to control the loss of fluids and gases from the wellbore.
Abstract:
A mixture composition of a cellulose ether made from raw cotton linters and at least one additive is used in a cement based dry mortar composition wherein the amount of the cellulose ether in the tile cement based dry mortar composition is significantly reduced. When this cement based mortar dry composition is mixed with water and applied to a substrate, the water retention, thickening behavior, and/or sag resistance of the wet mortar are comparable or improved as compared to when using conventional similar cellulose ethers.
Abstract:
A mixture composition of a cellulose ether made from raw cotton linters and at least one additive is used in a ready mixed joint compound composition wherein the amount of the cellulose ether in the joint compound composition is significantly reduced. When this joint compound composition is mixed with water and applied to a substrate, the water retention, sag resistance, and workability of the wet joint compound are comparable or improved as compared to when using conventional similar cellulose ethers.
Abstract:
A viscous breakable gel additive carrier for mixing with ion containing materials, including dry powder based and calciferous materials, which in its uniform homogeneous gel form, prevents separation and settling of the additives prior to mixing and is easily measurable, and upon mixing with the ion containing materials liquefies and becomes totally and evenly miscible to allow easy and precise mixing to produce uniform homogeneous mortars, grouts, stuccos and other compositions. The gel includes a predetermined amount of selected additives thoroughly mixed with a cross-linked polyacrylic acid gelling agent, an organic chelating agent, and an alkaline electrolyte, and prior to mixing with ion containing materials, has a consistency of a custard or jelly.
Abstract:
