Analyses of the matrices show dissolution of gypsum along with formation of sodium sulfate and calcium silicate hydrate. Moreover, the introduction of phosphogypsum to these matrices up to a mass rate of 6% has no significant effect on the mechanical strength. Beyond that rate, the compressive ...
of calcium sulfate hemihydrate: the α-hemihydrate form and the β-hemihydrate form. These two types of stucco are often produced by different means of calcination. While the P-hemihydrate form is normally used due to its lower cost, either type of calcium sulfate hemihydrate is suitable for ...
The invention adopts another technical proposal that: a method for preparing the calcium increased sand by using the cyclone boiler calcium increased cinder is characterized in that: the input calcium increased cinder is crushed by using a crusher, and the crushed calcium increased cinder is ...
Adding to cementitious binder and aggregate a low density calcium silicate hydrate sufficient to reduce the curing time; curing to setdoi:US7041167 B2Disclosed are concrete and fiber cement formulations and products comprising low-density calcium silicate hydrate, and methods for producing these ...
The method of drying the ingredients of a mixture for making concrete mortar includes first mixing them with a stoichiometric quantity of calcined chalk. This extracts moisture from the sand and cement powder, and heat is generated during transformation to calcium hydrate so that time and energy ...
