dc.description.abstractBroken bricks (BB) with dried calcium carbide residue (DCCR) is a potential pozzolana-lime cement. The BB contains mainly Si02, Al203 and Fe203 while DCCR contain Ca(OHh, the major components for pozzolana-lime cements. The BB-DCCR mixture met the ASTM C 593 requirements for use of pozzolana with lime. Rice husk ash (RHA) was used as control pozzolana in this study. BB-DCCRIcommercial hydrated lime (CHL) mixes developed higher compressive strength than RHA- DCCRICHL mixes at the 7th and 28th day of curing. BBDCCR mix exhibited a higher compressive strength than a BB-CHL mix. At the 28th day of curing, the BB-DCCR and BB-CHL mortar acquired a compressive strength of up to 15.4 and 13.2 MFa respectively. Thermal activation of poorly performing BB improved pozzolanic activity. The setting time of a workable paste of the BB-DCCR and BB-CHL met Kenya standard 02 1263 requirements for Portland pozzolana cements (PPC). The results of compressive strength suggested that the mixture of DCCR and BB could be used as cementing material.en_US
