    Abstract

    The increased demand for housing in the country and the continued strive for the government
    to provide affordable housing to citizens have influenced the need to cut cost of construction.
    Materials being the major contributor to the cost of construction have been the main focus and
    research on alternative construction materials has been ongoing.
    There has been also increased pollution on the environment by the non bio degradable
    plastics. Finding an alternative use for the waste plastics has been a major investment by
    private companies and governments.
    In an attempt to tackle these two challenges, this project report focuses on the research of use
    of waste plastic as binder to make plastic/aggregates blocks which can act as alternative
    construction materials.
    In this research three percentages of plastics composition were used i.e. 15%,20%,25% to
    make samples used to test for the mechanical and strength properties of the mixture. The
    material was tested for its compressive strength, flexural strength, density test and water
    absorption test. The properties were first compared to determine the effects of the different
    plastic composition and also compared to the local alternative materials such as burnt clay,
    concrete blocks and stone blocks.
    It was found that an increase in plastic composition improved the properties of the materials.
    The compressive strength improved from 1.37 N/mm² for the 15% composition to 1.97
    N/mm²for the 25% composition.
    Density reduced from 1.95 g/cm³ for the 15% composition to 1.85 g/cm³ for the 25% plastic
    composition. The water absorption reduced from 1.02 % for the 15% plastic composition to
    0.72% for the 25% plastic composition. The flexural strength increased from 0.16 N/mm² for
    the 15% plastic composition to 0.24 N/mm² for the 25% plastic composition.
    The results were compared to the set building standards and to the British standards regarding
    material strength requirements as discussed.
