A swarm intelligence shrinkage optimization of fly ash and tile aggregate based self-compacting concrete exposed to high temperatures

Engineering and Applied Science Research, 2023
Almost all the building structure is built with the basis ofSelf-compacting concrete (SCC). Hence, it has increased the researcher's interest in enriching the mechanical properties by optimizing the shrinkage.

Use of recycled concrete aggregate in concrete: a review

Journal of Civil Engineering and Management, 2013
The use of recycled concrete aggregate (RCA) in concrete as partial and full replacements of natural coarse aggregate is growing interest in the construction industry, as it reduces the demand for virgin aggregate.

Ultra-light foamed concrete mechanical properties and thermal insulation perspective: A comprehensive review

Journal of CO2 Utilization
Ultra-lightweight foam concrete (ULFC) is a relatively new construction material that has gained attention recently due to its unique properties. This material is not very heavy and low-density, making it easy to form into different shapes and sizes. Its

Hardened properties of high-performance printing concrete [PDF]

Cement and Concrete Research, 2012
This paper presents the hardened properties of a high-performance fibre-reinforced fine-aggregate concrete extruded through a 9 mm diameter nozzle to build layer-by-layer structural components in a printing pro- cess. The printing process is a digitally controlled additive method capable of manufacturing architectural and structural components without ...

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

FEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Fatigue life of case-hardened steel roller with an effective case-hardened depth of 2mm

Nihon Kikai Gakkai ronbunshu, 2014
In this study, case-hardened steel rollers with an effective case-hardened depth of 2 mm were fatigue-tested using a roller testing machine in order to elucidate their rolling contact fatigue life. They were made of three kinds of steels.
