1.5 STATEMENT OF THE PROBLEM
Apart
from bad mixing ratios, which happen even some sandcrete
blocksproducers add more yield of blocks, some other things can cause
blocks to be in bad condition which can affect the quality of the
sandcrete produced.
1.5.1 USING OF BAD CEMENT
Due to the
prevailingadverse economic conditions, some sandcrete block makers tend
to go for very cheap cement which may not have the required quality to
bind a solid block. These block break soon after they are made. Some
cement sellers who had cement keptin stock for so long sell it at give
away price to the sandcrete block makers if the notice that the quality
of the cement has detoriated.
1.5.2 RE-BAG CEMENT
Another thing to
note with cement is that some cement sellers re-bag cement, removing
some quantity of cement or put low quality cement product in a bag of a
high quality and trust cement brand. Theration you thought you are
using to produce a given quality has been compromised and it will
produce a low quality block that can easily break even before it is
being used for the project.
1.6 THE OBJECTIVE OF THE STUDY
This
project research will help us to understand the different strength of
sandcrete blocks produced with locally excavated sand and River sand.
This will also help to know the properties of Nsude sand after laboratory test has been carried out.
This
will help us in determining the moulding methods and properties of
sandcrete blocks. These properties are determined by the ratio of block
constituents such as cement, water and sand.
1.7 SCOPE OF THE STUDY
The
scope of this project work is limited to obtaining the comparison of
locally excavated sand with River sand in terms of strength in sandcrete
blocks.(Nsude as case study).
1.8 SIGNIFICANCE OF THE STUDY
To help us understand the strength of sandcrete blocks produced with locally excavated sand and River sand in Nsude.
To help us determine the properties of Nsude sand after carrying out laboratory test.
