“…They said this would occur because more water would be required in mixtures made unworkable by big aggregate sizes, thus resulting in concrete with lower strength. Arslan and Kamas [7] investigated the effect of varying size of the aggregates on the compressive strength of concrete cubes at 28 days. They created three-dimensional concrete models by idealizing the material properties such as modulus of elasticity and mass density that they obtained experimentally.…”

This study investigates the effect of aggregate size on the compressive strength of concrete. Two nominal mixes, that is, 1:2:4 and 1:3:6 were used in the study. Concrete cubes were produced with 6, 10, 12.5, 20 and 25 mm aggregates for the two nominal mixes and they were subjected to compressive strength test after curing for 7, 21, 28 and 56 days. It was found in the study that the strength development follows the same trend for both nominal mixes. Also, the results show that the compressive strength increases with increasing aggregate size up to 12.5 mm, while the concrete produced using 20 mm had greater compressive strength than those produced using 25 mm aggregate. This established the importance of ensuring that the right aggregate size is used in the production of concrete. Therefore, it is recommended that careful attention must be paid to the sizes of aggregates used in the production of concrete for structural purposes.

“…Active detection methods include stress wave method and electromechanical impedance (EMI) technique is widely used in structure healthy monitoring (Ai et al, 2016;De Oliveira et al, 2018) and damage detection (Yan et al, 2017;Tzoura et al, 2015). The EMI spectrum can reflect the structural changes based on the electrical impedance technology (Lu et al, 2018;Arslan and Kamas, 2017;Wang et al, 2014;Wang et al, 2015;Zhang et al, 2019). Shi et al (2018) investigated the feasibility of monitoring the compactness of concrete-filled fiber-reinforced polymer tube (CFFT) slurry based on the piezoelectric impedance method, and the experimental results showed that the variation of the conductivity characteristics could qualitatively determine the compactness of the slurry.…”

Purpose At present, piezoelectric impedance technology has been used in the study of wood damage monitoring. However, little effort has been made in the research on the application of piezoelectric impedance system to monitor the change of wood moisture content (MC). The monitoring method of wood MC is used by piezoelectric impedance technique in this study. Design/methodology/approach One piezoceramic transducer is bonded to the surface of wood specimens. The MC of the wood specimens increases gradually from 0% to 60% with 10% increments; the mechanical impedance of the wood specimen will change, and the change in the mechanical impedance of the structure is reflected by monitoring the change in the electrical impedance of lead zirconate titanate. Therefore, this paper investigates the relationship between wood MC change and piezoelectric impedance change to verify the feasibility of the piezoelectric impedance method for monitoring wood MC change. Findings The experiment verified that the real part of impedance of the wood increased with the increase of wood MC. Besides, the damage index root mean square deviation is introduced to quantify the damage degree of wood under different MC. At the same time, the feasibility and validity of this experiment were verified from the side by finite element simulation. Finally, MC monitoring by piezoelectric impedance technique is feasible. Originality/value To the best of the authors’ knowledge, this work is the first to apply piezoelectric ceramics to the monitoring of wood MC, which provides a theoretical basis for the follow-up study of a wide range of wood components and even wood structure MC changes.

“…Concrete manufacturing consumes a massive amount of raw material, such as natural aggregate and lime stone, which are among the basic and main components involved in concrete production and the cement industry, and these materials may soon be subjected to vanishing. Many researchers found that aggregates represent about 70-80% of concrete volume, and they have a vital role in various concrete characteristics such as consistency, strength and durability [4][5][6]. The increasing demand on concrete raises the alarm on the future availability of the natural aggregate resources for the coming generations, as natural aggregates were extracted by 28.6 gigatons in 2010 only and became the most extracted materials worldwide [7].…”

Aggregates are generally thought of as inert filler within a concrete mix, and a typical concrete mix is comprised of as much as 70–80% of them. They play an essential role in the properties of both fresh and hardened concrete. Nowadays, scientists are aiming to use waste materials, thereby replacing natural aggregates for economic and environmental considerations. This study investigates the effect of the utilization of steel slag by-product aggregates (air- and water-cooled slag) as concrete aggregates on the behavior characteristics of concrete. Various concrete mixtures, with different levels of replacement of slag aggregate (50, 75, and 100%), were conducted in order to find the optimum percentages to improve the microstructure and different properties of concrete (fresh and hardened). The results showed that increasing the fine aggregate replacement percentage led to a decrease in compressive strength values, in contrast with coarse aggregate replaced with slag aggregate. The steel slag aggregates showed potential to be used as replacement for natural aggregate with comparable compressive strength and acceptable workability.
