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

Study on overstrength and ductility of reinforced concrete building with different infill through nonlinear analysis

Structural Mechanics of Engineering Constructions and Buildings, 2021
The building structure with infill wall shows higher global stiffness along with the uncertain behaviour during 2015 Gorkha earthquake. It significantly increased the collapse rate of structures during earthquakes.

Effect of Thermal Bridges on Thermal Conductivity of Lightweight Block Units

NTU Journal of Engineering and Technology
The objective of this study is to develop lightweight hollow concrete blocks for use as partition walls instead of load-bearing walls. These blocks aim to improve thermal insulation by reducing heat transfer through cavities of varying dimensions and ...

Experimental Research on the Thermal Performance of Composite PCM Hollow Block Walls and Validation of Phase Transition Heat Transfer Models

Advances in Materials Science and Engineering, 2016
A type of concrete hollow block with typical structure and a common phase change material (PCM) were adopted. The PCM was filled into the hollow blocks by which the multiform composite PCM hollow blocks were made.
