Compressive Strength And Block-Mortar Bond Of A New-Type Of Insulation Hollow Block

This paper mainly studies the mechanical properties of hollow block made from shale, coal gangue and sawdust. In China, shale is gradually used as substitute material for clay in the manufacture of sintered masonry materials. The research goal was to provide basis for the generalization and application of the fired shale hollow block through uniaxial compress compression test and failure mode under biaxial stress state. Results showed that the hollow block had reliable compressive strength and bond strength with lower density and good thermal insulation performance, meaning the feasibility of application in practical engineering.
