If the calcium sulfate is added in the form of gypsum, it can become dehydrated at grinding temperatures of the order of 115130C or above, and can be present in a form which when mixed with water forms a supersaturated solution with respect to gypsum and from which secondary gypsum precipitates to provide a structure having some rigidity. This has the effect of stiffening the concrete or mortar and making it necessary to add additional water and thereby lower the strength-giving properties. This is known as false set and should be distinguished from flash set, which results in cements which have insufficient sulfate present effectively to stop the hydration of the tricalcium aluminate to the hydrate rather than to ettringite. Flash set is accompanied with the release of considerable amounts of heat whereas it is sometimes possible with false set (as its name implies) to break down the structure developed through vigorous mixing. Some of the problems with false setting can be alleviated by replacing some of the gypsum added to the cement by natural anhydrite. Other problems associated with the calcium sulfate addition arise when the clinker contains a relatively high SO5 content. As most cement specifications contain a requirement for a maximum SO3 level, the amount of calcium sulfate which can be added is restricted, and in that situation must be in a form where the solubility is sufficient to prevent the formation of the tricalcium aluminate hydrate rather than ettringite

The formation of fcc-free surface layer on cemented carbide can minimize the propagation of thermal cracks formed between the coating and the substrate into the bulk, which is caused by the thermal expansion mismatch between the coating and the substrate. Here, one example on DICTRA simulation of fcc-free surface layer formation on WCTi(C,N)TaCCo cemented carbides during one-step and two-step sintering in vacuum performed by Chen et al. [58] is demonstrated. The temperature profiles for one-step and two-step sintering in vacuum are schematically shown in Figs. 6.8(A) and 6.8(B). The end-point temperature for the simulation was chosen to be 1310C. The CSUDDCC1 mobility database, together with CSUTDCC1 thermodynamic database, was used for the DICTRA simulations. Only diffusion in liquid phase (i.e., binder phase) was considered, while the other two phases (WC phase and cubic phase) acted as point sinks or sources of solute atoms during the simulation. Considering the presence of the dispersed hard phase in the cemented carbides, a model for long-range diffusion occurring in a continuous matrix with dispersed phases [59] was adopted to simulate the gradient layer formation. A labyrinth factor (f) [60], which has been demonstrated by Mohammadpour et al. [61] to be linear in the volume fraction f of the binder phase, was employed. Thus, the effective interdiffusivity Dkjeffn in the binder phase can be given by

Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds.The result is called clinker, which are rounded nodules between 1mm and 25mm across. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement.The powdered cement is then mixed with water and aggregates to form concrete that is used in construction
