Effect of Calcium Carbide Waste Powder on Some Engineering Properties of Bamboo Leaf Ash Concrete

Abstract

The assessment of cement partially replaced with calcium carbide waste powder, CCWP and bamboo leaf ash, BLA on the strength of concrete made with cement was investigated. Oxide composition analysis of CCWP and BLA confirm their status as non-pozzolanic material rich in CaO component and pozzolanic materials, respectively. Setting times, slump, compressive and microstructure analysis tests were conducted on fresh and hardened concrete. Twenty-eight (28) and fifty-six (56) days peak compressive strength values of 13.23 N/mm2 and 15.97 N/mm2 respectively were obtained when 5% CCWP was mixed with 5% BLA plus 90% cement. Values comparable to 28 and 56 days peak compressive strength values of 13.03 N/mm2 and 15.07 N/mm2 respectively obtained when cement was only used as a binder. The use of CCWP and BLA in concrete will ensure economy in concrete production and a better way of disposing these wastes.
