Abstract:
One of the major challenges facing the construction industry is the growing concern over resource depletion, this is because the industry relies heavily on conventional materials such as cement, granite and sand for the production of concrete. The high and increasing cost of these materials has greatly hindered the development of shelter and other infrastructural facilities in developing countries. That has made the search for alternative materials that meet the performance standards of conventional materials imperative. The materials such as stone dust, palm kernel shells, sawdust and so on, used for this study were locally sourced for and the treatments of the study were as follows: T1 = Stone dust (4hp) + 25 kg of cement (control), T2 = Stone dust (2hp) + Grinded Palm kernel shell (2hp) + 25 kg of cement, T3 = Stone dust (2hp) + Saw dust (2hp) + 25 kg of cement, T4 = Grinded Palm kernel shell (2hp) + Saw dust (2hp) + 25 kg of cement. The results showed that T2 (stone dust + palm kernel shell + cement) performed better with a value of 4% compare to the value of T1 (stone dust + cement) with a value of 3% and respectively have the optimum compressive strength value of 13.20 KN/m2 compared to the value of T1 (stone dust + cement) with the control mix value of 14.3 KN/m3. In conclusion, T2 (stone dust + palm kernel shell + cement) was recommended as a partial replacement for stone dust in the production of unhollow block which will reduce the negative impact of this agricultural waste on our environment.
