Soil stabilisation is vital in foundation and
roadway building because it enhances soil
engineering qualities. The volumetric change
of expanding soil is seen as a challenge in
geotechnical engineering practice. The
stabilization method has to be safe. In this
study quarry dust (QD) in proportions of 5%,
10%, 15%, and 20% and lime in proportions
of 1%, 3%, and 5% were used to improve the
engineering qualities of laterite. The tests
carried out in this study were specific gravity,
proctor compaction, consolidation, particle
size distribution, Atterberg limits, and triaxial
and consolidation tests. The lateritic soil was
classified as A-3, A-2-4 and A-2-6 and was
found to be acceptable for sub-grade, good fill
subbase and base materials. The result
showed the highest CBR occurred at 5%
quarry dust and 5% lime. Results also
showed that the higher the percentage of
quarry dust, the strength of the soil. The
liquid limit (LL), plastic limit (PL) and
plasticity index (PI) of the natural soil
samples were 41.1%, 27.96%, and 13.14%
respectively. LL of the soil samples falls
between intermediate plasticity. The
experimental results in general, showed that
the admixtures (quarry dust and hydrated
lime) improved the engineering properties of
the soil.

Energy Piles

Hiba ., Sindhu V — Fri, 22 Sep 2023 00:00:00 +0530

Increasing demand for sustainable energy solutions has led to the exploration of innovative methods for harnessing renewable
energy sources. Energy piles, a geotechnical and structural engineering concept, have emerged as a promising technology that
combines foundation support with heat exchange capabilities. This comprehensive paper review examines the latest research and
findings from six prominent journals in the field of energy piles. The review focuses on key aspects such as thermodynamic
properties, design of energy piles, heat transfer performance, and the environmentfriendly utilization of energy piles. By synthesizing the insights from these journals, this review provides a holistic understanding of the advancements and challenges in energy pile technology, contributing to the ongoing dialogue on sustainable energy solutions.

Seismic Evaluation of Floating Columns in RCC Constructions with Various Soil Types

Roshani Khode, Rahul Sharma — Fri, 08 Dec 2023 00:00:00 +0530

Floating columns are aesthetically pleasing
and give more space for movement in the
parking lots of many multi-story structures.
Floating columns are not inherently more
prone to degradation than other types of
structures due to the way they are created.
The arrangement of various sections inside a
structure may present certain design
challenges that need to be carefully
considered to preserve the overall stability
and structural integrity of these parts. This
study examines the drawbacks of floating
columns at different building sites. Models of
the frame structure are analyzed using
STAAD PRO software of the floating columns
at different positions, such as at the centre
and the edge, for multi-story composite
buildings using the structural response of the
building concerning response spectrum
method for different zones to determine
results like storey displacement, periods, and
mode shapes. The performance of the floating
columns outside the composite construction
was superior to that of the floating columns
inside the building.

Determination of Spatial Distribution of Deep Boreholes in the Middle Aquifer in Monguno Town, Monguno Local Government Area, Borno State, Nigeria

Kadir Stephen Wagaja, Mustapha Hassan — Tue, 26 Sep 2023 00:00:00 +0530

The study determined the spatial distribution
of deep boreholes in the Middle aquifer in
Monguno. The inadequate water supply is
also poor in terms of quality as exposure to
the atmosphere (oxygen) reduces the
palatability and aesthetic value of the water
from the user’s perspective due to the
yellowish-brown coloration which is unusual
under ideal circumstances. Therefore, there is
a need to determine the spatial distribution of
the deep boreholes in the Middle aquifer of
Monguno Local Government area since it is
the predominant source of water supply. The
specific objectives of this study were to
determine the spatial distribution of deep
boreholes in the Middle aquifer in the area.
The method used in the study includes
primary data collected using measurement,
observation, and Field surveys conducted for
a site acquaintance to all existing deep
borehole sites in Monguno and taking their
geographical coordinates using GPS
equipment (Model: Garmin GPSMAP-64s
Receivers). The Borehole coordinates were
plotted on the geographical map of the study
area using ‘’Google Earth and ArcGIS’’
software to position them and show the
spatial distribution respectively to have a
pictorial view of the area. The major finding
of the research was that sampled water points
show the concentration of parameters and
possible health implications of using water for
drinking exceeding acceptable WHO (World
Health Organization) and Nigerian Standard
of Drinking Water Quality (NSDWQ) limits.
Based on the findings, the following
recommendations were made; Stakeholders
in water supply should support communities
with water treatment consumables such as
alum and filter cloths so that water treatment
can also be done at the household level
through coagulation and filtration.

Assessing Load Bearing Capacity of Bored Piles: A Comparative Review of Methodologies

Shubham Gupta, Vaibhav Singh, Chinar Garg — Thu, 14 Dec 2023 00:00:00 +0530

Determining the capacity of piles is crucial for
maintaining structural stability in a wide
range of construction projects. This
comprehensive review compares the
calculation of pile capacity utilizing three
distinct methodologies: the theoretical
approach, empirical methods, and field test
results, drawing insights from past research
works. The theoretical approach relies on
mathematical models and soil mechanics
principles to estimate pile capacity.
Conversely, empirical methodologies derive
from historical data and correlations derived
from past field experiments. Past studies have
extensively investigated and applied various
methodologies to estimate pile capacity. The
review systematically synthesizes findings
from prior research, delving into the
strengths and limitations of each
methodology. Studies employing theoretical
models often emphasize detailed insights into
soil behaviour but acknowledge challenges
related to assumptions that might not
universally apply. Empirical methods, while
expedient, sometimes lack accuracy across
diverse soil conditions or geologies, as
evidenced in previous investigations. Field
test results, despite providing practical data,
have been noted for their costliness and timeintensive
nature in various studies. Reviewing
past research work, it will guide engineers,
researchers, and stakeholders in making
informed decisions about the most suitable
methodology for calculating pile capacities in
diverse construction settings, thus
contributing to enhanced efficiency and
reliability in structural design and
implementation.
