Název v původním jazyce

Investigation of mechanical properties of cement pastes with fine recycled concrete as partial replacement for Portland cement: kind of method high-speed milling

Popis výsledku v původním jazyce

This article deals with mechanical activation of old concrete by high-speed mills and using recycled concrete powder as a partial replacement for cement. In particular, we focus on mechanical properties of cement pastes containing different kinds of fineness of micronized recycled concrete powder. As recycled materials, we used the monolithic construction of a column from a construction of supporting structures. Recycled material was milled by company LAVARIS Ltd. at high-speed milling process with different types of milling. Mechanical properties were obtained by non-destructive (resonance method) and destructive method. Investigated mechanical properties were the dynamic modulus of elasticity and the dynamic shear modulus, flexural strength and compressive strength. Results obtained from these materials were compared with the reference material.
