however, are generally of
trestle construction and of
limited span for carrying

(FBS) is better source of
cytokinin and could be an
alternative of using
synthetic cytokinin. Results
also revealed that using 7
ml and 12 ml concoctions
performs better in all
agronomic parameters. It is
recommended to use FBS
as a replacement of using
the synthetic cytokinin at
the levels of 7 ml and 12 ml
concoctions per litre of
water. Further study on the
effect of FBS must be
conducted to determine
significance in tiller
production of sugarcane.
Further research study for
the FBS to be analyzed for
cytokinin content and will
be used as fertilizer to
other crops and vegetables
are recommended to truly
validate the results.

PSRC, BRC, and PBRC was
compared to the flexural
test results of PRC which
served as the control
sample. The PRC and PSRC
beams are both reinforced
with steel, while the BRC
and PBRC beams are
reinforced with bamboo.
The PSRC and PBRC beams
contain plastic bottles
within while the PRC and
BRC beams do not. The
statistical results of PRC
compared to PSRC, BRC,
and PBRC showed a p-value
of 0.23 (insignificant), 0.01
(significant), and 0.00
(significant) respectively.
For costs, the beams were
separated into two groups:
beams with no bottles (PRC
and BRC) and beams with
bottles (PBRC and PSRC).
The beams with no bottles
are more expensive than
the beams with bottles by
9.2%.
Bamboo can serve as an
alternative building
material to steel
reinforcement. This paper
studies the results of

performance of housing

used as a chief construction

The bamboo culm, the
aboveground part of
bamboo, is one of the
oldest and most versatile
building materials used in
many construction
applications, particularly in
developing countries where
bamboo is called the “poor
man’s timber” due to its
fundamental utilization in
human communities. It is
well-accepted that bamboo
culms are a renewable and
lightweight material with
high strength. Therefore,
they can be used in building
applications, such as
scaffolding, flooring, walls,

The results show an
average level of awareness
of and experience in the
application of bamboo as
structural members,
particularly for roof and
wall construction. A major
area of application of
bamboo is as temporary
supports for formwork and
scaffoldings. The results
further indicate that the
use of bamboo for finishes
is uncommon.

experimental specimens
were realized varying the
concrete cross-section and
tested varying the
eccentricity of the applied
vertical load. Both
reinforced and nonreinforced panels were
tested. An analytical model
is proposed to evaluate the
load-bearing capacity,
based on dimensionless
curves, which provide
reduction coefficients of
strength based on
eccentricity and
slenderness, considering
second-order effects. The
analytical model
demonstrates a reliable
prediction of the

This study was carried out
to evaluate the effect of
TRCC permanent and
conventional temporary
formworks in RC columns
on key parameters of
confinement. These
parameters are,
respectively, the hysteretic
response, strength,
displacement ductility,
stiffness degradation,
energy absorption capacity,
damping ratio, residual
displacement, crack pattern
and failure mechanism. The
comprehensive
experimental investigations
have shown that TRCC
permanent formwork
improves confinement
efficiency. Consequently,
there is great potential for
use of TRCC permanent
formworks as an
alternative for conventional
formworks in the RC
columns.

that wood fiber could

The main aim of this article
was to determine
blemishes of concrete
surfaces and divide those
surfaces according to
following methods
provided by two
documents and by authors
proposed image scanning
method - "ImageJ". The
first method was CIB
Report No. 24 "Tolerances
on blemishes of concrete".
This method enables to
evaluate concrete surfaces
according to their visual
appearance by using
certain reference cards.
The second method was
GOST 13015.0- 83. This
method enables to
evaluate the concrete
surfaces according to their
biggest dimension of the
blemishes. The third,
authors proposed, method
was "ImageJ". Latter
method is based on the
free source computer
program. It helps to
establish the quantity and
the dimensions of the
blemishes in the desired
scale. Authors suggested to
imply a ration between
blemishes area and the allspecimen’s area as a factor
for evaluation of concrete
surface quality. Three

It is important for wood
plastic composites to
possess satisfactory
toughness and stiffness in
practical applications, such
as construction formworks.
In this study, an elastomer‐
grafted polyolefin (A669)
was introduced to improve
the toughness of wood
flour/polypropylene
(WF/PP) composites, with
talcum powder used as the
reinforced phase to
maintain the flexural
strength and stiffness of
the WF/PP composites. The
impact strength and
bending properties of the
composites were tested.
Differential scanning
calorimetry, dynamic
mechanical analysis, and
scanning electron
microscopy were used to
analyze this composite
system. Test results show
that the combination of
A669 and talcum powder
can provide the WF/PP
composites with both good

There are very limited

effects can be avoided by
replacing it with a

manufactured from OPT. In
Malaysia, palm trunk
plywood is used currently
for non-structural materials
such as formworks,

enhanced quality of palm

foundation is easy to

at avoiding a more

long time altering the
environment. This solution
for the realization of
foundation holes pays a
great part in reducing the
volume of digging and of
materials used in the
foundations, the quantities
of materials needing
transportation (soil,
concrete, steel-concrete,
wood for formworks, etc.)
as well as the shortening of
the construction period. All
these factors have
favorable impact upon the
environment, the
investment costs being
finally much smaller than in
the case of other known

Compared with wood
formwork, the concrete
surface using steel
formwork and PVC
formwork have higher
amount of small bugholes
and lower bughole area
ratio, but the influence of
formwork on the maximum
diameter of bugholes on
concrete surface is not
significant. The concretes
with different slump, mold
release agents and
formworks need different
vibration time in order to
decrease the bugholes on
concrete surface, although
long time vibration can
reduce the surface
bugholes, but the surface
bugholes are difficult to be
completely eliminated.
In the study reported here,
waste steel wires from
steel reinforcement and
used formworks were
blended with structural
lightweight concrete, with
the aim of replacing
commercial steel fibres of
controlled quality with
recycled fibres.
Compression, tensile,

were performed to assess
the mechanical properties
of 28 d old concrete
specimens reinforced with
mixed waste steel wires,

percentages of fibres
examined in the fibre

specimens were 0·25%,
0·50% and 0·75% (volume

With varying fibre contents,
similar trends were
observed in all the types of

The sustainable
construction aspects of
adopting prefabrication in
high-rise buildings are
examined, and the
economic, environmental
and social aspects of using
prefabrication are
assessed. A questionnaire
survey was administered to
experienced professionals
and case studies of seven
recent residential and nonresidential buildings in
Hong Kong were
conducted. The findings
revealed that
environmental, economic
and social benefits of using
prefabrication were
significant when compared
to conventional
construction methods. This
implies that a wider use of
prefabrication techniques
could contribute to
sustainable construction in
a dense urban environment
like Hong Kong.
Experimental results
indicated that both surface
treatment and penetrating
bars improve the
connection between GFRP

promote the ultimate
strength and rigidity of

the concrete used for

This paper reports on the
hygrothermal behaviour of
a new bio-based composite
building material, based on
recycled wood fibres used
as eco-aggregate within a
cementitious matrix. A
coupled heat and moisture
transfer was established
through the material and
resolved numerically with a
model developed herein.
Relative humidity and
temperature were chosen
as driving potentials. The
hygric and thermal
properties of the material
were analysed and then
used as input parameters in
the model. The accuracy of
the latter was verified by
comparing the simulation
results with experimental
hygrothermal tests, from
which the moisture
buffering value (MBV)
could be determined. The
MBV showed that the
wood-cement composite
material might contribute
to improve the indoor
thermal comfort and be
relevant for low-energy
building design.
The current research status
of building square timber
was summarized, and then
the commonly used
bamboo unit forms in
bamboo-based composite
materials were analyzed,
also well as several
bamboo-based composite
materials that might be
suitable for building square
timber. Finally, the
research prospect of
building bamboo square
timber was put forward.

The overlaid laminated
bamboo lumber (OLBL) was
developed for structural
applications with an aim to
substitute commonly used
building materials such as
steel and concrete. The
OLBL was, via a hot press,
fabricated by crosslaminating bamboo layers,
bamboo mats and phenolic
impregnated adhesive
papers. Since the weight of
OLBL was governed by the
high-density bamboo layer,
the panels made of OLBL
had a relatively highdensity value of about 850
kg/m3. In this study, a
lightweight panel was
developed by a proper
arrangement of radial
bamboo curtain. The major
and minor directions of a
panel were the paralleland perpendicular-to-its
length direction,
respectively. It was found
that 1) the density of an
OLBL panel could be
reduced by about 20%; 2)
the failure occurred in the
bamboo node(s); 3) there
was a significant difference
in effective modulus of
elasticity and effective
modulus of rupture
between two panel
directions; and 4) there was
a good relationship
between the density and

Thus, the current piece of
work attempts to address
two major issues, namely:
(1) Energy consumption of
industrial refrigeration in
production of Ice
Formwork. (2) Changes in
water mineral content after
a cycle of Ice Formwork
concrete production. For
both topics, the research
work required
development of an original
experimental methodology.
This aspect has been given
the great attention and
required development of
new technical solutions on
many levels. Further
research and development
is needed to come to a
comprehensive
environmental assessment,
and the results of the
current study merely
provide a preparatory
overview that can help to
orient and properly set the
objectives for the following
research stages.

besides, the core layer

plywood strengthened by

simultaneously had the
best performance, and the
structure which satisfies
the strength requirements
of building formwork are DP/E and D-E/P.
Experimental findings are
accompanied with
theoretical model.
This paper focuses on the
facing quality of the
reinforced concrete and
formwork surface at
various temperatures for
both conventional and selfcompacting concretes. A
series of experimental tests
have been conducted in the
laboratory to determine
the optimal polarization
parameters (voltage value,
time and duration of its
application). On-site tests
were then performed to
observe the scaling effect.
Results indicate that the
proposed polarization
technique can indeed
provide an effective means
to separate the concrete
from its formwork without
requiring demoulding oil.
Concrete mixtures
implemented both in the
laboratory and on-site
display high-quality facing
without the presence of
any attachment points. A
chromatographic analysis
of the concrete pore
solution and water
transported by electroosmosis shows that ion
concentrations remain
unaffected. This
polarization approach can
thus be used as an
alternative to avoid the use
of oils of a chemical or
petrochemical origin.
