Abstract:
Due to a high construction material cost in Ethiopia, it is difficult to afford a shelter by most our peoples. The Hydra form block (HFB) has been identified as low-cost building material with its potential and possibility to reverse the housing problem. Laboratory tests were conducted on Mettu, Nopa, Gore, and Hurumu areas soil.... More
Abstract:
The evolution of industries is essential for the economic growth of any country; however, this growth often comes with exploitation of natural resources and generation of wastes. The safe disposal and utilisation of industrial wastes has become essential for sustainable development. A possible approach would be to utilize these wastes in construction industries. The stone...

Abstract:
This research focuses on investigating the effect of quartz particle size and cement replacement on their physicomechnical properties. Portland limestone cement (PLC) was employed and replaced with quartz powder (QP) at various particle sizes (1.19 mm, 425 µm, 300 µm, 212 µm, <212 µm) and cement replacement between 2.5 wt.% ~ 15 wt.% at interval...

Abstract:
This work examined the structural properties of concrete obtained by partially replacing cement with sawdust ash. The sawdust ash which is a pozzolan was obtained by burning sawdust which is a waste product from processing of timber in an open air. The burnt ash was passed through a 150 µm metric sieve to obtain the... More
Abstract: In this study, the laboratory tests on the influence of pre-saturation of gravel on the mechanical properties of concrete were carried out. The study accessed the specific gravity, water absorption capacity, the impact and the crushing values of the coarse aggregates. Also, this study determined and compared the compressive strengths of concrete produced with the... More
Abstract:
This work was on non-activated and activated lateritic soil used in proportions of 0 % to 30 %, to replace fine sand by wt. %, in the production of lateritic concrete. A mix of 1: 2: 4 was used, and the cube samples were cured in four (4) curing media of water, sand, polythene, and... More
