Dieter Naumannhe width of cracks if cracking is not to be excluded in general. In the paper the analysis of the impact of a cooling pipe system (CPS) on the changes of temperature and strains in a RC semimassive wall was presented. In the numerical calculations a model covering non-linear and non-stationary tempe

Dieter Naumanntes is the environmental aspect—it is partially made by utilizing waste products, such as fly-ash, slags, and others. It has been estimated that geopolymer binder production makes up to 6 times less CO. than the production of Portland cement. Due to the polymerization or in other words nature of the

.S in cement chemistry notation), which forms at lower temperatures, is a promising solution to develop eco-efficient and sustainable cement-based materials, used in enormous quantities. However, the slow reactivity of belite limits its application. To understand the reasons behind, dissolution mech

Chemical Equilibrium,equilibrium for a reaction by changing its pressure, temperature and/or concentration. A catalyst does not affect the equilibrium position. Rather, it changes the reaction mechanism, substantially increasing the speed of the reaction.
