چکیده
For the production of building reinforcing steel, special charge components were used, consisting steel waste, cast iron shavings and about 20 % NVG pellets. Steel was smelted in a 60-ton electric arc furnace. The pouring liquid carried out on continuous casting machine. Heat treatment immediately after rolling operation to improve physical mechanical properties construction steels melted furnace from material using metal waste. It is recommended that these be made low-carbon (C≤0.25 %) low-alloy order have sufficiently high technology good weldability. However, meet requirements standards, must structural integrity properties. found can solved only by heat armature. In this case, effect obtained fittings hardening due temperature. Therefore, further during thermomechanical (TMT), directly (immediately) deformation roll. Immediately spread, properties, as well fluidity strength reinforcement met standard conducting HTMT. Increased technological are achieved dispersion at high-temperature tempering, which temperature more than 580 °C

متن کاملINFLUENCE OF ADHESION AT STEEL/MORTAR INTERFACE ON CORROSION CHARACTERISTICS OF REINFORCING STEEL By
The mechanism of corrosion of reinforcing steel in concrete is discussed based on electrochemical and electron microscopy observations. The importance of calcium hydroxide precipitation on the steel surf ace in the steel/mortar interface is evaluated by placing filter paper around reinforcing steel bar specimens prior to casting in mortar, thus preventing direct contact between steel and mortar...
متن کاملStrain hardening and heterogeneous deformation during twinning in Hadfield steel
We identify the role of deformation twinning and twin–twin intersections on the strain hardening behavior of Hadfield steel single crystals using strain field measurements. In situ and ex situ strain field measurements resolved at micrometer length scales are obtained using digital image correlation. Ex situ measurements reveal that macroscopic twin-bands, which are composed of a mixture of fin...

Analytical strengths of reinforced concrete beams and columns based on reinforcing steel stress-strain curves with and without a sharp yield plateau and the nonlinear stress-strain behavior of concrete are compared with strengths calculated in accordance with the ACI Building Code to determine the feasibility of using the 0.2% offset method to define the yield strength of reinforcing steel. Com...
