A textile reinforcement method for 3D printed concrete [PDF]

MATEC Web of Conferences, 2022
The reinforcement of 3D printed concrete elements has proven to be a significant challenge that needs to be addressed. However, before reinforcement can be applied, the behaviour of the consequent composite materials must first be studied.

A Life-Cycle Approach to Investigate the Potential of Novel Biobased Construction Materials toward a Circular Built Environment

Energies, 2022
Conventional construction materials which rely on a fossil-based, nonrenewable extractive economy are typically associated with an entrenched linear economic approach to production.

Analysis of Thermal Resistance of Developed Energy-Saving External Enclosing Structures with Air Gaps and Horizontal Channels

Buildings, 2023
New energy-saving enclosing structures with air gaps are proposed; when calculating the temperature fields in the enclosing structures, the method of finite element analysis in the ANSYS environment was used.

Multi-layered cement-hydrogel composite with high toughness, low thermal conductivity, and self-healing capability

Nature Communications, 2023
The inherent quasi-brittleness of cement-based materials, due to the disorder of their hydration products and pore structures, present significant challenges for directional matrix toughening.

CO2 Utilization and Market Size Projection for CO2-treated Construction Materials

Frontiers in Climate, 2022
Achieving a net climate benefit requires that captured CO2 (from stack emissions, directly from air or any other source) does not return to the atmosphere. There are several negative-emissions technologies that will meet this criterion.
