Consequences of dewatering cement mortars incorporated with ground Bayburt stone

Abstract

The detrimental effects of the rapid dewatering of cement mortars due to the interaction of wet mortar and brick substrate at the freshly mixed state in masonry construction are often addressed in the literature. The desorptivity and hence very high water releasing ability of cement mortars result in a great water loss during dewatering that significantly affects the fresh and hardened state properties of the end product. The paper therefore investigates the possible role of ground Bayburt stone incorporation in cement mortars on dewatering characteristics and the consequences of this effect at the hardened state properties of these mortars in construction practice. The paper begins with the measurement of the parameters of water transport kinetics and individually reports the effect of dewatering on the mechanical properties and durability characteristic of cement mortars incorporated with ground Bayburt stones. The results reported in this paper strongly suggest that ground Bayburt stone incorporation in cement mortars significantly compensate the degree of dewatering, and this vital feature does not only decreases the influence of dewatering on mechanical properties but also results in an enhanced durability characteristics of cement mortars.
