An Investigation of
the Suitability of
Kerang And
Miango Volcanic
Ashes for the
Production of
Ceramic Bodies
and Glazes
2011
PGS/20062007/302028
The study was inspired by the desire to
investigate on more materials for
ceramic production from the immediate
environment. It targeted the utilization of
the abundant volcanic ashes that are
found in Kerang and Miango, both in
Plateau State, Nigeria for the
development of ceramic bodies and
glazes. Basically, this study comprised
field, laboratory and studio work.
Importantly, theoretical framework was
reviewed on the following areas:
Sampling of ceramic materials, mixing
(coning and quartering) of sampled
materials,
milling
(beneficiating)
ceramic
materials,
compounding
ceramic bodies, determining of shrinkage
values, determining of apparent porosity
and water absorption, and glaze
blending. Materials were beneficiated
following prescribed schemes and
laboratory analysis carried out to
determine concentrations of elements in
each of the samples under study. The XRay
fluorescence
spectrometric
technique (XRF) was used for this
purpose. The materials were tested for
plasticity/particle size, shrinkage, and
for porosity. The samples were processed
in schemes adapted from ASTM C326-76
AREA FOR
RESEARCH
FURTHER
and C373-72 on shrinkage, porosity and
water absorption tests. Glazes were
subsequently
compounded
through
blending volcanic ashes of Kerang and
Miango with volcanic cinders, tuff,
volcanic glass and Jos feldspar in sixty
six member triaxial test and in thirty six
member quadrilateral tests to determine
their suitability for glazes. 12000C was
found to be the most suitable operational
temperature for both ceramic bodies and
glazes. The results of the property test
revealed that volcanic ashes from
Kerang and Miango had coarse particles
which made volcanic ash to possess low
plasticity especially for throwing
purposes. When blended with Barkin
Ladi Kaolin however, ratios 7:3 and 6:4
of volcanic ash to kaolin were found to
be most suitable for ceramic body
formation. 56 out of 138 blends,
representing 41% of glazes mixed were
found to be good, producing glazes with
gloss, semi-matt and matt effects. The
glazes are recommended to potters as
they were found to be stable.

Studies on the
Qualities of
Alkaleri Kaolin in
High – Fired
Ceramics
2000
PG, 0484
The art and science of high - fired
ceramics though closely associated with
the construction of high temperature
kilns is mostly associated with the
mastery of materials science. Kaolin, a
high temperature ceramics material is a
common feature in the geology of
Northern Nigeria. The Alkaleri kaolin
deposit in the North - East of Nigeria
having been quantified. deserves study to
determine its suitability for high - fired
ceramics. The samples were beneficiated
and tested for physical and chemical
properties as prescribed by ASTl'vl
Standard C 326 - 76, C-325 - 81, C- 323
- 56, C - 343 - 72 with some
modifications. Furthermore, both the
Biaxial and Triaxial blends of each
kaolin with other high temperature fluxes
and stoneware clay were carried out to
form bodies and glazes. The Chemical
Analysis of the kaolin samples reveal
that they are high in Alumina, high in
Silica, low in impurities and have a high
Loss of Ignition. The Sieve Analysis
revealed the coarse nature of the kaolins.
They also recorded a high percentage of
sand and a low percentage of clay
content. The physical tests also reveal
the low plasticity of the kaolins. The
kaolins recorded a linear shrinkage of
between 12% - 13% and an Abscrption
Rate of between 15.5% and 17.4%. the
Rafin Makaranta Secondary Clay
recorded an Absorption Rate of 1.39%.
Strong bodies emerged from the Biaxial
and Triaxial blends. The bodies recorded
a linear shrinkage rate of between 9%
and 13%, the China bodies recorded the
highest linear shrinkage rate. The China
bodies fused in firing and equally
recorded the lowest Absorption Rate.
The highest Breaking Strength was
recorded by the China bodies. The
refractories still open, absorbed the most
and recorded the lowest breaking
strength. The stonewares cast well in the
mould while the China and Porcelain
bodies
presented
some
casting
difficulties. Some of the glazes derived fit
the bodies, others, crawled. An analysis
of variance carried out confirmed the
reliability of reporting in percentages at
P ,0.001, P < 0.005 and P < 0.001 for
the Absorption Rate and Shrinkage Rate
data.

Investigation into
the Qualities of
Selected Metal
Jewelries
2008
PGS/20002001/304040
The quality of various jewelries that are
commonly used by women in Bauchi was
investigated
by
determining
the
percentage concentration of metals
present in them using X - ray
fluorescence
(XRF)
spectrometric
technique. Gold, copper, nickel, and
nickel - silver, silver and brass jewelries
were sampled from the different markets
in Bauchi metropolis and were ground
for XRF analysis. Hardness of jewelries
was also determined using the Rockwell
Hardness
tester.
The
elemental
percentage concentrations in the
jewelries indicate copper to be in
relatively
high
percentage
of
concentrations in the different jewelries
than other metals. Calcium and some
heavy metals occur in varying
percentage concentrations in the
different jewelries at low levels. The
result of the hardness test showed gold,
nickel - silver, copper and brass to be
higher than Brass and nickel. The result
of the hardness was correlated with the
percent metal composition. The jewelries
revealed positive correlation P s 0.05 in
some metals. The presence of heavy
metals in jewelries suggests potential
health hazards associated with the use of
such jewelries

Exploitation and
Adaptation of
Biogas to Ceramic
Kiln
2004
PG NO. 00016
'Appropriate technology' concept was
adopted in constructing and adapting the
'floating-drum' (underground) biogas
digester for firing ceramics. Following
series of pilot biogas firings directly
from the 2m3 floating drum (under ATP)
and in existing 10 CF kerosene kiln, less
than acceptable (maximum) temperature
of 234°c was obtained. Thus, a 4.5 CF
model kiln became necessary and,
designed and built. This was followed by
requisite compression of the biogas into
pressure cylinders (between 10 & 28
bars). Subsequently, another series of
regular firings, from the pressure
cylinders, were conducted. A biscuit
temperature of 90Qoc (with about 22m3
storable biogas) was recorded, using
standard analogue pyrometer and
pyrometric cone.

Pollution Control
in Nigerian Metal
and
JewelryIndustries
2004
PG. NO 00369
This study was motivated by both the
national and international concerns over
critical environmental pollution issues
and the challenges to scholars, members
of the academia and researchers to look
into the possibility of controlling
pollution within their locality for
sustainable development. The Nigerian
Metal and Jeweuery industries formed
the area for this study with samples
randomly selected from two clusters
within
the
study
area.
Questionnaires/interview
were
administered and the chi-square method
instrument was used to analyse data
from the questionnaires. Results of
laboratory analysis and information
collected during inspection visits were
used to further consolidate these
findings. The end results have indicated
significant correlation between the
activities of metal and jewellery
industries and environmental pollution in
the study area. Consequently, it is
concluded that the air, water and soil
qualities of the study area were impaired
and therefore it is recommended that the
existing Nigerian environmental laws
and regulations be enforced to ensure
compliance by those industries with set
standards to check further pollution and
environmental degradation.

Appraising the
Availability,
Usage and Impact
of Non-Print
Instructional
Media in Nigerian
Federal
Universities of
Technology
2010
PGS/20082009/304030
The study set out to appraise the
Availability, Usage and Impact of Nonprint Instructional Media in Nigerian
Federal Universities of Technology.
Four out of the five Federal Universities
of Technology were studied. An
instrument for the study which was a
questionnaire was designed in two sets,
one for the lecturers, called 'Teachers
Opinion Questionnaire (TOQ)'; and the
other for the students called 'Students
Opinion Questionnaire (SOQ)' was
administered on the selected target
population. The data collected was
analysed and presented using simple
percentages and bar charts to show the
general information pictorially in terms
of their bars after the data had been
converted to percentages. A decision
mean of 2.50 was used to decide on
whether the factor existed or not, in
answering the research questions. A ttest at 0.05 level of significance was used
to test the hypotheses. The result of the
analysis showed that the extent of
familiarity (knowledge) of the non-print
instructional media in the Federal
Universities of Technology was not
significant. The items were in common
use (according to the literature
reviewed) in most developed and some
developing countries of the world. Where
they were familiar with the items, the
data showed that they were not available
for use in the universities. The ones that

were available and used in teaching had
positive impact on the learning process
of the students. Based on the findings, it
was recommended that university
administrations should make available
non-print instructional media to both the
staff and students, for effective teaching
and learning purposes. Also the Federal
Government should increase the
budgetary allocation of universities to
enable them acquire sufficient quantities
of the non-print media for both teaching
and learning processes by the teachers
and students respectively.

An Assessment of
Risk in BuildOperate-Transfer
(BOT) Scheme for
University Hostel
Projects in Nigeria
2013
PGS/20042008/3060179
One of the newest financial schemes for
environmental projects is the Build.
Operate, and Transfer (BOT) concept,
which is being used increasingly
worldwide as a project delivery system
by which governments obtain the
infrastructure projects from private
sector after a concession period free of
charge. In the Nigerian environment, the
concept have been adopted for the
provision of students hostels in the
Universities but up to now, promoters
and investors haw had many fears
toward the proposed projects. This study
assesses the risks for implementing the
BOT system in the Nigerian universities.
The data used were collected from the
selected Universities through the use of a

combination of structured questionnaires
and
structured
interviews
with
stakeholders and a follow up case study.
Various statistical test procedures
including Risk Rating Index. One factor
analysis of variance b) ranks (Kruskal \\'allis test i. Delphi probability
technique and Pareto analysis, were
used in the research investigation.
During the course of the work, it was
discovered that conventional risk
assessment: ~l;;!'r\.'~lChes Illel) not be
effective in privatized infrastructure
projects because of the fact that. ti~e: ha.
e \ cr) long project lifecycle with many
sector specific risk factors. From the
result it \\ as discox ercd that the
assessment of complex risks is often a
difficult task when past data 011 similar
risks are not available. Analyses of the
identified risks shows that among the
political risk subfactors, termination of
concession by government and increase
in taxes (specific) ius the highest risk
rating index of 0.836 and 0.738 and were
therefore rank I and :2 respectively and
hence more severe. Similarly. in
construction, cost overrun and increase
in financing with RRI of 0.760 and 0.689
were respectively the most severe;
operation has labour risk and change in
cost of operation with RRI of 0.780 and
0.765 respectively as the most severe.
Market and revenue risk have monopoly
and insufficient tariff with RRI of 0.856
and 0.780 respectively as the most
severe. Financial risk has insufficient
evaluation of future inflation and
fluctuation in foreign exchange rate with
RRI of 0.780 and 0.745 respectively as
the most severe. Legal risk has breach of
financial agreements and title/lease of
property with RRI of 0.620 and 0.610
respectively as the most severe. These
findings were confirmed by the case
study of Emerald hostel project. Finally.
a risk probability and impact assessment
framework is proposed which prox ides a
systematic method to identify, assess and
determine the relationship. importance of
specific risks across BOT projects
