The present invention relates to a three component composition consisting of a polyol component (A) comprising at least two polyols, one with high and one with low molecular weight, and water, a polyisocyanate component (B) comprising a methylene diphenyl diisocyanate (MDI) product with an average NCO functionality of at least 2.5, or a methylene diphenyl diisocyanate (MDI) product with an average NCO functionality of at least 2 and at least one further polyol with an amount of between 1% and 30% based on the weight of said polyisocyanate component (B), wherein said MDI product and said polyol have reacted at least partially, and a powder component (C) comprising at least one hydraulic binder, preferably cement and/or calcined paper sludge, preferably a calcium compound selected from calcium hydroxide and/or calcium oxide, and optionally one or more aggregates. Polyurethane cementitious hybrid flooring or coating systems having glossy/semiglossy surfaces, good workability and outstanding mechanical properties can be achieved. Blister formation can be avoided.

The Invention is related to increasing of early strength and final strengths of cements classified under EN and ASTM as Portland or CEM cements and also related to all clinker employing cements and to any kinds which employ calcium sulphates for set optimization and is for composing of new cements by only assessing new methods for production and is for composing of new cements by only assessing new methods to formation and inclusion of calcium sulphate resources which are used for set optimization. A new calcium sulphate resource is obtained by employing lower heats and this input is arranged to different dehydration levels at which they can be most efficient for the selected use. These different dehydration levels are called intermediate phases of dehydrate or hemihydrates or called as monohydrate.

The present disclosure concerns an aluminosilicate having a Blaine fineness of about 500 m.sup.2/kg to about 3000 m.sup.2/kg and/or a specific surface area of about 4 m.sup.2/g to about 20 m.sup.2/g, as well as the uses thereof. The present disclosure also comprises a dry cementing composition and a mortar or concrete composition, the compositions comprising said aluminosilicate. The present disclosure also comprises a process for the manufacture of aluminosilicate. The process comprises: roasting a spodumene concentrate in an acid medium; leaching the acidic roast spodumene concentrate so as to obtain a mixture comprising a solid comprising the aluminosilicate and a leachate; and separating the aluminosilicate from the leachate in an acid medium, wherein said aluminosilicate contains a calcium concentration of less than about 5%.

The present invention is directed to a plaster composition with a reduced carbon footprint and a method of making and using such plaster composition. In one aspect, the plaster composition may include a workability composition and a binder. When hydrated with water, a hydrated plaster composition may have enhanced workability, enhanced surface texture, enhanced finish, and may have a reduced carbon footprint as compared to a traditional plaster composition.
