Description
This thesis reveals the role of different clay minerals in the fired brick production process. Multiple in-situ characterisation techniques have been effectively combined to study the thermal behaviour of clayey materials added with kaolinite, expandable vermiculite, and nanofibrous palygorskite at various dosages. Laboratory-scale brick buttons are obtained to test the mineralogical composition, mechanical strength, density, porosity, colour, water absorption, and thermal diffusivity. The conclusions obtained can effectively assist brick manufacturers and researchers in achieving optimised clay mix design to obtain maximum economic efficiency and quality.
Impact and interest:
Citation counts are sourced monthly from Scopus and Web of Science® citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
