摘要:
The present description relates to method of initiating the curing of carboxylic acid-treated material compositions to enable an initial lowering of the viscosity and stiffness of the material for low temperature wetting and coating of solid surfaces, for paving, for waterproofing, for roofing, and for underlayment applications. The present description relates to ecologically sound, non-toxic technology that enables a practitioner to improve the low-temperature cracking properties of a material or material composition while also inducing a rapid increase in the high-temperature stiffness and viscosity of the material or material composition, and to rapid cure and strength development of finished product composition for application in paving, roofing, adhesive interlayer bonding, roll finishing, blow-molding, water-proofing, and underlayment.
摘要:
Methods for cementing a subterranean well and maintaining zonal isolation involve preparing a cement slurry that contains water, an inorganic cement and an expanding agent. The slurry is placed in the annular region between casing and the formation or between two casing strings. After the cement sets, the expanding agent reacts and causes the set cement to be in a state of compression within the annular region. The casing dimensions may fluctuate in response to a temperature change, a pressure change, a mechanical disturbance resulting from a well intervention, or mud contamination or a combination thereof. The expanding agent may further react and maintain a state of compression within the annular region. The state of compression in the annular region may be monitored by acoustic impedance measurements.
摘要:
The invention relates to a pulverulent composition for dispersion and/or dissolution in water, comprising 5% by weight to 98% by weight of chalk and at least one substance having water retention capacity and at least one hydrophilic additive and additionally a hydrophobic additive. More particularly, the invention further relates to the use of the pulverulent composition, for example, as a spackling compound, casting compound, paint, cosmetic product or wellness product. The invention also relates to a container (1) for said composition, comprising at least one pouch (3) having at least one opening provided with at least one closure means (2).
摘要:
In the present invention, a hydraulic binder is rapidly cured using either: (1) a liquid quick-setting agent for a hydraulic binder, comprising aluminum sulfate or a hydrate thereof, an aluminum oxide or hydroxide, at least one organic acid, at least one alkaline earth metal oxide or hydroxide, and water; or (2) a combination of (A) a liquid quick-setting agent which contains aluminum sulfate or a hydrate thereof, an aluminum oxide or hydroxide, at least one organic acid, at least one alkaline earth metal oxide or hydroxide, and water; with (B) a non-slurry auxiliary quick-setting agent which contains powdery aluminum sulfate or a hydrate thereof. In accordance with the present invention, a quick-setting agent system which is easy to use, produces little dust, is non-alkaline, and is capable of exhibiting good curing properties even under conditions which are difficult to carry out construction with conventional quick-set concrete.
摘要:
The present invention relates to a binder comprising calcium sulfoaluminate (CSA) cement and a magnesium compound, to a method of enhancing strength development and/or increasing compressive strength of building structures from CSA binders and to the use of magnesium compounds as additives for increasing compressive strength of hydrated CSA binders.
摘要:
Disclosed herein are gypsum products with at least one high efficiency heat sink additive. The gypsum products, e.g., gypsum panels, are less susceptible to the damaging effects of extreme heat as the temperature rises due to the presence of the at least one additive.
摘要:
Inorganic-organic composite articles and methods for producing them using inorganic acidic/alkaline precursor components as inorganic adhesives is provided. Articles prepared therefrom provide improved flexibility, zero flame spread, no release of volatile organic compounds, and low carbon foot print.
