Title: Performance evaluation of plain concrete made from phyllite aggregates

Abstract: This work reports on research done to evaluate the performance of plain concrete made from phyllite aggregates and granite aggregates. Aggregate property tests revealed that the phyllite aggregates were flaky and elongated with relative unit weight of 2.72. The mechanical properties with respect to water absorption, aggregate impact, aggregate crushing, Los Angeles abrasion and 10% fines were within the specification by the British Standards for aggregates used for structural concrete production. The density of phyllite concrete lies between (2300-2850) kg/m3 therefore produces normal weight concrete. Results of tests on 400 cubes and 210 prisms made of phyllite and granite concrete over a period of 360 days revealed that concrete made from phyllite aggregate achieved about 80% of the compressive strength of what concrete made from granite aggregate achieved in all the concrete classes considered in this limited test.
