In this study, rubberized concrete interlocking bricks have been developed by utilising crumb rubber (10) and fly ash (56) as partial replacements of sand and OPC, respectively. It is aimed to develop mean and characteristic compressive strength correlations of rubberized concrete interlocking hollow and grouted wall systems, corresponding to rubberized concrete interlocking brick and prism strengths. A systematic investigation of 20 rubberized concrete interlocking brick units, 10 hollow and grouted rubberized concrete interlocking prisms and 10 identical hollow and grouted rubberized concrete interlocking wall panels were cast, constructed and tested under compressive load. Results were statistically analysed and the design-charts for the mean and characteristic compressive strength of masonry were used. The results obtained for the strength of rubberized concrete interlocking brick, prism and wall revealed a normal distribution with 5 significant interval. Four types of regression models were proposed for statistical analysis and the best fit model was identified based on r2 (correlation coefficient). The power model for the mean and characteristic strength curves presented the best fit to the sorted data. The cracking pattern and modes of failure of the tested specimens were discussed. The relationships for characteristic strengths of rubberized concrete interlocking masonry hollow and grouted wall were derived in terms of rubberized concrete interlocking unit and prism strength and found to be fkw = 1.533fb 0.290, fkw = 2.178fb 0.337 and fkw = 1.119fp 0.659, fkw = 1.023fp 0.731, respectively. © 2020 Institution of Structural Engineers date: 2020 publisher: Elsevier Ltd official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85083343525&doi=10.1016%2fj.istruc.2020.04.010&partnerID=40&md5=3e4f67c082070b91420c3f267a698213 id_number: 10.1016/j.istruc.2020.04.010 full_text_status: none publication: Structures volume: 26 pagerange: 169-184 refereed: TRUE issn: 23520124 citation: Al-Fakih, A. and Mohammed, B.S. and Wahab, M.M.A. and Liew, M.S. and Mugahed Amran, Y.H. and Alyousef, R. and Alabduljabbar, H.
