EVALUATION OF COMPRESSIVE STRENGTH OF CONCRETE WITH BROKEN POT MATERIALS AS PARTIAL REPLACEMENT OF COARSE AGGREGATE
Abioye T., Bello A. G. & Abdulrazak A. Y.

ABSTRACT
Coarse aggregate is a primary ingredient for making Concrete for various construction works, including infrastructure development, low, and high-rise buildings and domestic development. It occupies about 65-80% of the concrete. Broken pot materials (B.P.M.) are waste-generated pot-making processes and day-to-day activities. The broken pot material (B.P.M.) may replace natural coarse aggregate. The broken pot (B.P.M.) was sourced from pot-selling markets/stalls at Tundun Wada and Kofar Gabas in Sokoto. Concrete of 0%, 5% and 10% replacement were produced and cured for 28 days after which the cubes were tested for strength development. It was observed that the strength of 5% replacement was lower than that of 0% while that of 10% replacement was the lowest. However, the strength developed for 5% and 10% were 27.37N/mm2 and 22.11N/mm2, which are acceptable for 1:2:4. It is therefore recommended that, where available in abundance, broken pot materials be incorporated in Concrete to replace coarse aggregate.
