![]() ![]() The discovery that a coarse sand such as mason sand may be used in combination with the dry cement composition of this invention, to prepare a liquid free-flowing, self-leveling and self-smoothing coating formulation, was both unexpected and surprising. ![]() There is no requirement that fine sand, having a relatively fine particle size distribution, be used as the added aggregate in the coating formulation. The fine sand component of the dry cement composition typically represents only about 10 to about 20 wt % of the total aggregate present in a coating formulation prepared from such dry cement composition, with the balance of aggregate being added at the job site, i.e., about 80 to 90 wt % of the required aggregate being blended with the dry cement composition at the job site.Ī further advantage of the dry cement composition of this invention is that the aggregate added to the dry cement composition may be any readily available coarse grade of sand, such as mason sand, or an equivalent aggregate. The amount of sand in the dry cement composition represents a relatively small amount of aggregate, as compared to the coarse sand or equivalent aggregate that is subsequently combined with the dry cement composition, along with water, to make a flowable, self-leveling and self-smoothing coating formulation. C04B2111/62- Self-levelling compositionsĪn advantage of the cement composition of this invention is that it contains a relatively small amount of sand, i.e., aggregate, a factor that allows the dry cement composition to be economically shipped from the manufacturing site to end-use sites that are relatively long distances from the manufacturing location.C04B2111/00- Mortars, concrete or artificial stone or mixtures to prepare them, characterised by specific function, property or use.polycarboxylate cements containing hydraulic cements other than calcium sulfates C04B28/02- Compositions of mortars, concrete or artificial stone, containing inorganic binders or the reaction product of an inorganic and an organic binder, e.g.C04B28/00- Compositions of mortars, concrete or artificial stone, containing inorganic binders or the reaction product of an inorganic and an organic binder, e.g.MORTARS, CONCRETE OR LIKE BUILDING MATERIALS ARTIFICIAL STONE CERAMICS REFRACTORIES TREATMENT OF NATURAL STONE C04B- LIME, MAGNESIA SLAG CEMENTS COMPOSITIONS THEREOF, e.g. ![]() C04- CEMENTS CONCRETE ARTIFICIAL STONE CERAMICS REFRACTORIES.HERBERT Priority to CA002249878A priority patent/CA2249878A1/en Priority to EP98308179A priority patent/EP0916629A1/en Application granted granted Critical Publication of US5873936A publication Critical patent/US5873936A/en Anticipated expiration legal-status Critical Status Expired - Lifetime legal-status Critical Current Links (A MINNESOTA CORPORATION) ASSIGNMENT OF ASSIGNORS INTEREST (SEE DOCUMENT FOR DETAILS).
