This research paper delves into the prospects of the concrete block production industry in Nigeria, analyzing its current state, challenges, and potential for growth.

Essential Points. Most of the aggregates possess a relative density within 2.4 – 2.9 with a similar particle density of about 2400-2900 Kg/m 3 (150-181 lb/ft 3).; Hereabouts, for coarse aggregates, the standard test process has been described in ASTM C 127(AASHTO), and for fine aggregates, the standard test practice has been described in ASTM C 128 (AASHTO).

Purpose This paper aims to investigate the 28-day compressive strength of concrete produced with aggregates from different sources.
