4. INTRODUCTION
Cassava starch is a substance with high colour
(whiteness) low dirt and fiber content that
possess a strong firm, good water holding
properties and stable viscosity (Frost et al, 1997).
The word refractory means hard to fuse. It is a
material which can withstand higher temperature,
resist action of corrosive liquids and dust – laden
current of hot gases. This refractory material
consist usually a mixture of oxides obtained from
naturally occurring materials capable of resisting
load at higher temperature (Chester, 1986).
5. AIMS AND OBJECTIVES
This project is aimed at investigating suitability of
cassava starch as a binder for the production of
refractory bricks.
Specifically, this research will
• Produce refractory bricks
1 using cassava starch as the
binder;
• Determine the effectiveness of
T
2 producing a refractory bricks
using cassava starch as the
binder; and
• Determine some of the
3 properties of the refractory
produced.
6. SCOPE OF THE STUDY
This study involves the investigation of the suitability of
cassava starch as a binder for production of refractory
bricks and as such it entails:
Obtaining cassava starch and the refractory material
(Calcium Oxide);
Production of refractory bricks from cassava starch;
Ascertaining its suitability by carrying out physical
test analysis like its porosity, permeability, crushing
strength, abrasion resistance, erosion resistance and
linear shrinkage etc.
7. PROPOSED METHODOLOGY
The proposed methodologies are:
•Sample Collection;
•Crushing and Grinding;
•Sieving Analysis;
•Pre – treatment;
•Mixing;
•Moulding;
•Drying;
•Firing;
•Drop Number Test; and
•Porosity Test.
8. JUSTIFICATION OF THE STUDY
Because of the demand and cost of refractory materials for Nigeria
industries to thrive better, there is a need to source for refractory
binders’ locally like the cassava starch to reduce the cost of obtaining
refractory for such process. This then calls for a research to
investigate the suitability of cassava starch as binder for production
of refractory bricks. It will also at the end of this research reveal
weather cassava starch can act as a good binder or otherwise.
The choice of methodology is based on the fact that cassava starch is
a substance with high colour (whiteness), low dirt and fiber content
that possess a strong firm, good water holding properties and stable
viscosity which will at the end of this research weather cassava can
act as a good binder or otherwise
9. PROGRESS MADE
The chapter one and two have been written
and submitted to the supervisors. Samples
has been collected and is being prepared for
the production of refractory bricks using
cassava starch as a binder.
