EP0218363A1 – Magnesium phosphate fast-setting
improved magnesium phosphate fast-setting cementitious compositions containing a carboxylic acid, salt or acid derivative. These compositions form a hardened mass when water is addet at ambient temperatures. The incorporation of the carboxylic acid, salt or acid derivative within these compositions retards the initial setting time, increases the early compressive strength of the resulting …Cited by: 12

Process for making reinforced magnesium phosphate fast
Mar 26, 1991· Several fast-setting magnesium phosphate cements were made to test the effect of the addition of fibers. A fast-setting cement with compressive strength of 4700 psi after two hours when reinforced with 2.4% steel fibers gave 4900 psi after two hours and when reinforced with 4.7% steel fibers gave 5100 psi after two hours.
Magnesia–ammonium phosphate-bonded cordierite …
The setting reaction of magnesium phosphate cements starts with water addition to a mixture of ammonium phosphate and magnesium oxide, is very fast and takes place at room temperature (cold setting).
US4755227A – Production of solid phosphorus pentioxide
A solid phosphorus pentoxide containing material suitable for use in fast-setting cements can be produced by a process which comprises mixing a porous material with a liquid, phosphorus pentoxide containing material and heating the mixture until a dry solid is produced. The solid phosphorus pentoxide containing material thus formed can then be dry blended with a solid component comprising …Cited by: 25

Integrated marking materials – MBT Holding AG
Rapid setting patch materials shall be used to patch a designated site, typical of a standard repair. The site will be evaluated after one year’s exposure. Approval will be based on visible signs of distress, such as cracking, crazing, scaling, spalling, wearing, edge fraying, corner cracking, or debonding.
Feb 04, 2003· In the dry formulation, the hydraulic or cementitious binder is a hydraulic cement, preferably a portland cement such as that used for highway, bridge, or airfield runway construction, and the like, or quick setting cementitious binders such as magnesium phosphate or magnesium potassium phosphate cement, or any other suitable hydraulic binder.
