Investigation of the mechanical and thermal performances of concrete hollow blocks [PDF]

SN Applied Sciences, 2020
In order to improve the thermal performance of external masonry walls, the impact of the blocks’ internal configuration on both their mechanical strength and thermal properties is numerically investigated. Ten different configurations with approximatively similar void ratios of about 40% (38.25–40.5%) and same external dimensions (40 cm × 20 cm × 10 cm)

Engineering Biochar‐Derived Functional Materials for High‐Performance Supercapacitors: Design Principles, Mechanisms, and Scalable Strategies

Carbon Energy, EarlyView.
ABSTRACT Biochar has emerged as a useful and adaptable source of carbon for supercapacitor electrodes. Its value comes from the way biomass chemistry, thermal conversion, and activation conditions shape the resulting pore network, surface groups, and degree of carbon ordering.

The regulation of mechanical properties and freeze-thaw properties of concrete hollow block with granite waste

Journal of Asian Architecture and Building Engineering
Owing to the generation of waste during mining and processing, granite stone causes great damage to the environment. In this study, the broken granite waste and the stone powder were used as concrete coarse aggregate and “admixture” to make granite waste

Numerical and Experimental Evaluation of a Simplified Lateral Spring Formulation for Rocking Structures

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Rocking podium isolation systems have gained significant research interest as a method of limiting seismic demands on superstructures and eliminating residual post‐earthquake drifts through self‐centring behaviour. However, while numerous models of varying complexity, including analytical, phenomenological, and physical formulations, have been
