TORSIONAL AND CRACKING BEHAVIOURS OF NORMAL WEIGHT AND COCONUT SHELL LIGHTWEIGHT CONCRETES [PDF]

open access: yesJournal of Engineering Science and Technology, 2018
Modern-day structures using conventional concrete, which is tall and aesthetically pleasing is in need of torsional strengthening. The ability of a structure to withstand twisting forces about a longitudinal axis is called torsional strength.

Comparison of lightweight and normal-weight aggregate concrete

open access: yesDÜMF Mühendislik Dergisi, 2022
In this experimental study, lightweight aggregate concrete (LWAC) and normal-weight aggregate concrete (NWAC) were compared within the contexts of the size of calcium hydroxide (CH) crystals in interfacial transition zone (ITZ), compressive strength, and oven-dry density. Six LWAC and NWAC mixtures were prepared for this study.

The Rapid Chloride Migration Test in Assessing the Chloride Penetration Resistance of Normal and Lightweight Concrete

open access: yesApplied Sciences, 2021
Chloride-induced corrosion has been one of the main causes of reinforced concrete deterioration. One of the most used methods in assessing the chloride penetration resistance of concrete is the rapid chloride migration test (RCMT). This is an expeditious

Behavior of Reinforced Composite Foamed-Normal Concrete Beams

open access: yesJournal of Engineering, 2023
A study has been undertaken to investigate the production and behavior of beams made with foamed, normal, and composite concrete and reinforced with different steel percentages (under, balanced, and over). Nine reinforcement beams, including three normal-

Lightweight aggregate concrete produced with crushed stone sand as fine aggregate

open access: yesCogent Engineering, 2020
Lightweight aggregate concrete mixtures incorporating 0, 10, 20, and 30 weight percent replacement of normal-weight aggregate with lightweight aggregate and crushed stone as fine aggregate were tested at 7, 28, 56, and 90 days for various strength and ...
