Mortar Consumption Characteristics of ‘Brickwork’ and a Framework for Managing Brick and Mortar Walls in Chaotic Environments

Engineer: Journal of the Institution of Engineers, Sri Lanka, 2012
This study investigated how bricks and mortar could be used in a chaotic environment where brick and joints sizes could be varied to achieve better outcomes (such as cost minimisation) through an understanding of mortar consumption characteristics of brickwork. This was made possible by integrating three innovative concepts, viz.

Utilizing residual waste particles from polyethylene terephthalate (PET) waste pellet production in cement mortar

International Journal of Sustainable Engineering
Polyethylene terephthalate (PET) bottle waste management is a global challenge, with PET pellet production generating 20-23% waste particles (PWP). These particles, when deposited in landfills, do not decompose and can disperse, posing health risks ...

Integrated product development and lifecycle management in building production – A case study for logistic of mortar distribution in building sites

Journal of Building Engineering, 2020
In this work, there was developed a modular container based on the principle of integrated product development (IPD), as a device to facilitate the distribution of mortar between workplaces during the production of a multi-story building, as part of the IPD strategy applied to a project under development.

Bone‐Inspired Recyclable Composites for Damage‐Tolerant Circular Materials

Advanced Functional Materials, EarlyView.
Bone‐inspired architected composites are developed by combining osteon‐like reinforcements with a recyclable Elium thermoplastic matrix. The hierarchical architecture redirects cracks and promotes energy dissipation, while enabling recovery of intact, aligned, load‐bearing reinforcement units that retain their original stiffness, revealing a route ...

Assessment of Sieving as a Mean to Increase Utilization Rate of Biomass Fly Ash in Cement-Based Composites

Applied Sciences, 2023
Biomass fly ash is a growing challenge for combustion by-product (CBP) management. This research was conducted to investigate the influence of activation by sieving through a 63 µm sieve and a 125 µm sieve on fresh and hardened cement mortar properties ...

CO2‐to‐CO Conversion in a Gas‐Fed, Zero‐Gap, PEM Electrolyzer Enabled by Polycations and Nitrogen‐Doped Carbon‐Supported Cobalt Nanoparticles

Advanced Functional Materials, EarlyView.
A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)
