Material characterisation of thin layer mortared clay masonry
Highlights Material properties of thin layered mortared masonry were characterised. High bond strength mortared specimens lead to mix mode of failure. Low bond strength mortared specimens behave similar to conventional masonry. Prism compressive strength was quite higher than the conventional masonry.
Abstract Although thin layer mortared (TLM) masonry has potential economic benefits over conventional masonry construction, the lack of understanding on material and structural characteristics under various loading situations hamper its widespread usage. Hitherto few systematic research studies were reported on this masonry system. Therefore in order to better understand the material characteristics, an experimental programme was carried out to characterise the TLM clay masonry and its constituents. Tensile bond, shear bond, flexural and compression strengths and deformation characteristics of TLM clay masonry were investigated in this research using clay bricks with proprietary and laboratory made mortars. The results have revealed that the TLM masonry exhibit failure modes different to the conventional masonry: however, where the bond strength commensurate to the conventional mortar, the distinction between the TLM and conventional masonries vanishes. Therefore it is recommended to select appropriate TLM type suitable for the design requirements. Additionally the research generated data of key material properties that might be useful for nonlinear numerical analysis of TLM masonry.
