Mechanical performance of structural lightweight concrete with metallurgical coal aggregates [PDF]

open access: yesScientific Reports
Many studies have investigated industrial by-products as alternatives to natural aggregates; however, little attention has been given to metallurgical coal (MC).

Mechanical behaviour evaluation of scrab tire based rubberized lightweight and normal structural concrete and response at elevated temperatures [PDF]

open access: yesScientific Reports
In recent years, the exponential increase in the world population had led to sharp increase in discarded scrap tires, creating a serious ecological problem. In addition, environmental and social damage that occur during the extraction of aggregate is one

Method of calculating the optimal sand content in normal-weight concrete

open access: yesИнженерно-строительный журнал, 2018
In the practice of proportioning concrete compositions, the optimum sand content in a mixture of aggregates is usually found empirically. The disadvantage of this approach is the considerable complexity and duration of the required tests.

Prediction of flexural fatigue life and failure probability of normal weight concrete

open access: yesMateriales de Construccion, 2022
Fatigue life has to be considered in the design of many concrete structures at various stress levels and stress ratios. Many flexural fatigue test results of plain normal-weight concrete are available in the literature and almost every set of test ...

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
