A STUDY OF DYNAMICALLY COMPACTED CONCRETE DEFORMATION BY LASER INTERFEROMETRY METHODS

Abstract

Dynamically compacted concrete is obtained by mechanical casting of mixture to the surface to be poured. To study the deformation peculiarities of dynamically compacted heavy-weight concrete such methods are necessary that enable registration of deformation fields of its macro- and microstructure. To this end laser holographic interferometry methods were applied. There methods ensure contact-free inertialess registration of deformation fields in a wide range of dynamic and static loads.
