Abstract: An ultrasonic shear wave-based nondestructive method is proposed in this paper to detect steel–concrete interface debonding owing to the top-bar effect. A concrete wall was cast with horizontal reinforcements at different ...

Abstract: In reinforced concrete construction, deflection control is an important performance criterion for its serviceability and sustainability. In this paper, an experimental program aimed at modeling the effects of both short-term ...

Abstract: The macro-finite-element (MFE) modeling proposed in this paper is dedicated to the calculation of the deflection of already cracked reinforced concrete beams under service loading at the stabilized cracking stage. MFEs are ...

Abstract: This paper investigates the microstructure and autogenous shrinkage of calcined kaolinitic clay-limestone (LC) blended cement paste composites up to 200 days. The calcined clay-limestone content ranged between 20% and ...

Abstract: This study investigated the performance of two alkali-activated concretes (AACs) subjected to marine exposure for 2 years. The AACs were synthesized from a low-calcium Class F fly ash (FA) and a blast-furnace slag. ...

Abstract: This paper focuses on the effect of supplementary cementitious materials on early-age mechanical and viscoelastic properties of concrete, restrained shrinkage-induced cracking, and time to cracking. Compressive strength, ...

Abstract: Ferronickel slag (FNS) which is also known as electric arc furnace slag is a byproduct of the production of ferronickel alloy. The production of FNS at Société Le Nickel (SLN) in New Caledonia is about 2 Mt per year ...
