Abstract

An opportunity is discussed to improve operational parameter stability of concrete and reinforced concrete articles on Portland cement basis in heavy-duty environment. Demonstration of binding properties of cements with identical normative parameters was shown to be dissimilar under amended operational conditions. Such behavior may be supposedly connected to insufficiently stable relation between alkalinity and dispersity of consumed Portland cement.It was found feasible to arrange preventive control of incoming Portland cement with due consideration of its application conditions. The results of such control were shown to be efficient at substantiated correction of applied Portland cement activity.The purpose of this research has been expansion of methodological basis of mineral binder quality control for stabilization of consumer properties of concrete and reinforced concrete structures produced on their basis.
