1.1 BACKGROUND OF THE STUDY
A lot of research activities have
been carried out on lateritic sills but little emphasis have been laid
on the relationship between plasticity (consistency limit) and
compressibility characteristics. Negligence on the part of construction
engineers have led to uncountable road and structure failure within the
Sub-Sahara Africa. According to Ashworth (1996), it was revealed that
lateritic soils are graded with deficiency in sand and silt size
particles. Ola (1974), investigated stabilization problems associated
with laterite and the modified result is used in production of blocks.
Balogun (1982), investigated some physical and geotechnical properties
of laterite soil in Shagamu, Southwestern Nigeria, this found to have
significant difference in some index properties and crushing strength of
three Southwestern Nigeria lateritic clay deposits with the aim of
seeing how the materials could be used for bricks. The result of the
findings showed that firing increase the strength tremendously. A
problem laterite soil is those that do not yield reproducible result
using standard laboratory testing procedures. The soils are difficult
to evaluate as engineering construction materials. The peculiar problem
of this soil have been identified as thermal and mechanical
instabilities i.e the susceptibility to significant change on the
addition of small levels of the thermal or mechanical energy. This
research project is to investigate the characteristic properties of
lateritic soil located at Irewole Local Government, Ikire in Osun State,
Opposite Saw Mill, by using Groundnut shell ash as an alternate binder
at various percentage replacement to know the effect which those
pozzolanic has on this selected laterite soil sample which will be
determined in the laboratory by multiple compaction test among others.
The result have from this test shall be used to determine the
characteristic properties of the selected sample as well as to design
for its mixing proportion when needed for civil engineering projects
1.2 AIMS AND OBJECTIVES AIMS T
he
aim of this research work is to determine the effect of Groundnut shell
ash on lateritic soil properties so as to determine the best mix
design.
