    • ABSRACT - [ Total Page(s): 1 ]In this study, the compressive strengths and Modulus of elasticity of lightweight Concrete with oil palm shells as partial replacement of coarse aggregate was presented. The different types of mixing water were used, namely, clean water from Ahmadu Bello University Water Works, Salt water, obtained from Lagos Shore and Pond water obtained from Nagoye, Zaria. Also three mix ratios were adopted which include 1:2:4, 1:1.5:3 and 1:1:2 mix ratios. Five mixes were investigated; control, which contain granite coarse aggregate only; then four other mixes with 20%, 40%, 60% and 80% granite coarse aggre ... Continue Reading

         

      CHAPTER ONE - [ Total Page(s): 1 ]CHAPTER ONEINTRODUCTION1.1              PreambleNatural resources of the world are drastically dwindling due to the increasing demand of natural aggregate for the construction industry. The frequent use of natural aggregate in some areas led to environmental degradation, and has given impetus to studies and researches for sustainable development by using different waste products in the construction industry. Lightweight aggregates from industrial waste such as fly ash, ground granulated blast furnace slag, bed ash has led to sustainable materials but due to the lac ... Continue Reading
