| dc.description.abstract | Papercrete bricks are lightweight bricks incorporated with paper pulp from paper waste, and are basically used in non-load-bearing structures like partition walls. Preliminary tests were done on the papercrete bricks and results showed a low compressive strength value of 4.48 MPa and high water absorption rate of 21.85%. This study was aimed at assessing the suitability of using Expanded Clay Aggregates (ECAs) to improve papercrete by improving its compressive strength and water resistance. The methods used to attain the objectives include the Particle Size Distribution, bulk density and water absorption tests to determine the physical engineering properties of ECAs, efflorescence, soundness, water absorption and compressive strength tests on the bricks with ECAs to determine the ECAs’ effect on the bricks’ physical properties, and the compressive strength test on the wall prototype made using claycrete composites to determine its structural load-bearing capacity. The key parameters looked at in this study include the ECAs ratios and curing periods of the composites. This research identifies that 20% of ECAs and 28 days of curing gave the best results. | |
