Total five (05) mixes of concrete have been examined using calcined kaolin (CK) of 0, 5, 10, 15 and 20 by weight of cement. For each mix, compressive strength, splitting tensile strength and flexural strength have been determined by preparing three specimens. The effect of CK on the mechanical properties of HSC has been investigated at age of 7, 28, 56 and 90 days. Multiple linear regressions through least square error have been used to develop the expression and to predict the compressive, splitting tensile strengths and flexural strength of HSC. It has been found that CK as CRM increases the strength significantly. The models may predict the strengths closely match the measurements and optimum replacement of cement by CK. © (2014) Trans Tech Publications, Switzerland. date: 2014 publisher: Trans Tech Publications Ltd official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84903511535&doi=10.4028%2fwww.scientific.net%2fAMM.567.375&partnerID=40&md5=4a8eff7a3f804ab86aad19b47b1f01c1 id_number: 10.4028/www.scientific.net/AMM.567.375 full_text_status: none publication: Applied Mechanics and Materials volume: 567 pagerange: 375-380 refereed: TRUE isbn: 9783038351238 issn: 16609336 citation: Nuruddin, M.F. and Khan, S.U. and Shafiq, N.
