Abstract: In this study, calcium carbide residue, a by-product fromproducing acetylene gas, was mixed with fly ash from Mae Moh, aby-product from coal burning in electricity generating, to be used as acementitious material. Cementing property was expected by a pozzolanicreaction of the two materials. Normal consistency and setting times ofpastes of cement, fly ash, and calcium carbide residue were investigated.For mixture of mortar, flow and compressive strength were studied.Before using as a cementitious material, calcium carbide residue wasground until the remained on sieve number 325 was not more than lo%,while fly ash and cement remained on the specified sieve of 22.6 and4.05%, respectively. The fineness of calcium carbide residue, fly ash, andcement, in term of Blaine, were 9216, 3126 and 3299 cmL/g, respectively.The results revealed that the amount of water for normalconsistency was increased with the increase of the amount of calciumcarbide residue in the paste. The setting times of pastes of calcium carbideresidue mixed with cement, fly ash or fly ash and cement were found tobe lasted longer with the higher portion of calcium carbide residue in themixture. The flow of mortar was found to increase with the decrease ofcalcium carbide residue. The mixture of 30% of calcium carbide residueand 70% of fly ash produced the flow of 111 which compared as thesame flow of standard mortar of 113. For compressive strength, it wasfound that the mixture of calcium carbide residue and cement resulted in alower compressive strength as compared to the standard cement mortar.The mixture of calcium carbide residue and fly ash gave a betterperformance since the development of high compressive strength by usingpozzolanic reaction had been observed. After 60 days of curing, thepercentage of compressive strengths of calcium carbide residue-fly ashmortar were constant as compared to that of the standard mortar. It wasalso found that the highest compressive strength of calcium carbideresidue-fly ash mortar was achieved with a mix proportion of 30% ofcalcium carbide residue and 70% of fly ash. The compressive strength ofmortar was of 209 kg/cmL or 36% as compared to the standard cementmortar strength.
