    • 3.0    OBJECTIVES OF THE STUDY
      The aim and objectives of the project is to:
      -    Evaluate the strength of the concrete when polymers are used along side with other construction materials and when they are not used along side with other construction material.
      -    Examine the water absorption capability of this kind of composite.
      -    Determine the best mix ratio for the materials used for the production of this composite.
      -    Reduce the amount of environmental waste in the country in general.
      4.0    SCOPE OF THE PROJECT
      The scope of this project focused on the effect of reprocessed “pure water sachet” (PWS) on the physical and mechanical properties of wood wool (Omo wood). The physical properties include water absorption and dry density of the cubes; while the mechanical property includes the compressive strength test of the cubes.
      5.0    METHODOLOGY
      The methodology includes the following:
      -    Procurement of materials needed for the production of the specimen: wood, pure water sachets, cement and water.
      -    Using of a manual hand wooden smooth machine to remove the shavings from the wood.
      -    Production of reprocessed pure water sachet (PWS).
      -    Construction of the formwork or moulds for the wooden wool cubes of dimension 50mm X 50mm X 50mm.
      -    casting of wood wool cement  cubes.
      -    Physical and mechanical test is carried out on the cube.
      -    Analysis of results, conclusion and recommendation.

      CHAPTER TWO - [ Total Page(s): 4 ]Resistance of wood wool cement board against fungi attack also depends on the alkaline nature of the cement, since these micro-organisms prefer slightly acidic environment. Wood wool cement board have a thermal resistance of 0.18m2 ho/Kcal, a board specific gravity of 0.6 and thickness of 15mm respectively: thermal resistance increase with a decrease in specific gravity and an increase in thickness (Shigekura, 1989). While on the other hand, sound absorption was rated as 0.75 at 4000c/s for boar ... Continue reading---

         

      CHAPTER THREE - [ Total Page(s): 1 ]CHAPTER THREEMETHODOLOGY3.1    INTRODUCTION    The production of the cubes involves the construction wooden moulds, acquisition of materials, mixing of the cube materials, pressing and curing. A laboratory test on the physical and mechanical properties of the cube is carried out.3.2    MATERIALS PROCUREMENT    The wood planks used were procured from the sawmill at Irewolede and it is commonly known as Omo wood (Alstonia Longesis). The wood planks were cut into thinner planks with a m ... Continue reading---

      CHAPTER FIVE - [ Total Page(s): 1 ]4.3    DISCUSSION OF RESULTS    The average density of the cubes produced without reprocessed pure water sachets and having a mix ratio of 2:1:1 is 706.66kg/m3 while the average density of cubes produced with processed pure water sachets and having a mix ratio of 2:1:1:1 is 810.67kg/m3. The average density of the cubes produced without reprocessed pure water sachets and having a mix ratio of 1:1:1 is 437.33kg/m3 while the average density of cubes produced with reprocessed pure water sachet ...
