Adhesion to concrete of new types of rebar rolled products for construction

Cover Page

Abstract


This article discusses the background and history of the emergence of innovative, popular today, types of rebar for construction, their distinctive features and quality indicators, the methodology and results of various studies conducted on the basis of NIIZHB named after A.A. Gvozdev of JSC Research Center of Construction and LLC “Technological Institute ‘VNIIzhelezobeton’ ”. The purpose of this article is to introduce new types of innovative rebar products and demonstrate their advantages. For the tests, the results and methods of which are given in the article, test rolls of rebar with a four-row screw profile were made. In terms of strength and deformability of adhesion to concrete, the reinforcement with multi-row (four-row and six-row) reinforcement profiles significantly surpassed the reinforcement with two-row crescent (European) and screw (GEWI-Stahl analog) profiles. It has demonstrated high adhesion to concrete not only in the operational, but also in the extreme stage of deformation of the reinforcement.
