CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE1.0 INTRODUCTIONSoil is the cheapest and the most widely used material in civil engineering project as foundation material either in its natural or improved form. It is highly heterogeneous and an isotopic in nature and existing with different engineering properties which can be influenced to some extend by the presence of sodium salts under the influences of water (Olawale, 2013). The properties of soil as an engineering material depend on its surface electric charges, chemical c ... Continue Reading
CHAPTER TWO - [ Total Page(s): 6 ]ReactionNacl(s) +H2SO4aq → NaHSO4aq + HCl1 Then, the sodium hydrogen tetraoxosulphate (vi) react with more sodium chloride to form the sodium tetraoxosulphate (vi)NaHSO4aq + NaClaq → Na2SO4aq + HClg (Michigan, 1990)2.4.2 CHEMICAL PROPERTIES OF SODIUM (II) TETRAOXOSULPHATE (VI) SALT Sodium sulphate (NaSO4) displays a moderate tendency to form double salts which is the only alum formed with common trivated metal which unstable above 39 (degree)C and NaCrSO4 (Soskatchewan,1990). In contrast to potassium sulphate and ammonium sulphate which form many stable al ... Continue Reading
CHAPTER THREE - [ Total Page(s): 3 ]PROCEDURES• Liquid limit: A sample weighing 200g from the material passing the 300um BS test sieve was taken.• The sample was placed on flat glass plate and mix thoroughly with distilled water using the palette knife unit the mass becomes a thick homogonous paste.• The paste was allowed to stand in air tight container for about 24hours to allow the water permeate throughout the soil mass.• Curing was applied to where applicable and remix for about 10 minutes• A portion of the remix soil sample was placed in the cup of the casangrade l ...
