چکیده
• A new approach is presented for determining the diagonal cracking resistance. The method not dependent on subjective visual appraisals of cracks. results are obtained by using conventional measuring instrumentation. Concrete mixes containing EAF steel slag aggregates have been assessed. An alternative experimental predicting shear resistance steel-reinforced concrete beams developed in this paper. Conventional extensometric strain-gauge rosettes placed lateral surfaces a set four beams. As propagates through beams, load–strain curves flatten out at plateau and mechanical property under consideration may be determined. applied to cast from pumpable self-compacting with cement types I IV electric arc furnace aggregates. feasibility applying standard design code formulas concretes these therefore studied compared other recent research works. Accurate were without having interrupt test specimen.

Experimental Investigation of Corrosion Cracking in Reinforced Concrete Beams Containing Nano Wollastonite
Cracking of the concrete cover due to corrosion is defined as the serviceability limit state of reinforced concrete structures. This study evaluated the influence of a mineral admixture i.e. nano wollastonite on corrosion performance and serviceability of reinforced concrete structures by performing an accelerated corrosion test on ten reinforced concrete beams under a sustained load. To do so,...

Abstract: A new reinforced SFRFLC (abbr. steel fiber reinforced full-lightweight concrete) superposed beam was proposed to sufficiently utilize the good peculiarities of ordinary concrete in compression and SFRFLC in tension, and reduce its self-weight. Experimental study was carried out on the flexural behaviors of reinforced SFRFLC superposed beams compared with reinforced concrete beams and ...
متن کاملExperimental Investigation on Shear Cracking Behavior in Reinforced Concrete Beams with Shear Reinforcement
This paper presents an experimental investigation to clarify shear cracking behavior of reinforced concrete beams. The effects of the various influential parameters on the spacing between shear cracks and the relationship between shear crack width and stirrup strain at the intersection with shear cracks were carefully investigated. It was found that shear crack width proportionally increases wi...
