The purpose of the experimental work presented in this study is to study the effect
of concrete compressive strength and steel reinforcement ratio on capacity and
deflection of reinforced concrete two-way slabs. Three steel reinforcement ratios are
considered which are minimum, maximum and average of them in addition to two
concrete compressive strength
values of 20 and 30 MPa. The results from
experimental work show that increasing the reinforcing steel ratio leads to increase the
ultimate capacity of the slab in addition to decrease the maximum deflection. For slabs
with
= 20 MPa, increasing the reinforcing steel ratio from the minimum to the
maximum, i.e. 600 %, leads to increase ultimate capacity by about 156 % and decrease
maximum deflection by about 52 %. Wheras, For slabs with
= 30 MPa, increasing
the reinforcing steel ratio from the minimum to the maximum, i.e. 900 %, leads to
increase ultimate capacity by about 155 % and decrease maximum central deflection
by about 27 %. In addition, matmatical expresions for load-deflection relationships are
presented in the current study
Effect of Coarse Aggregate Size on the Compressive Strength and the Flexural ...IJERA Editor
Concrete structures deflect, crack, and loose stiffness when subjected to external load. Loss of flexural strength of concrete is largely responsible for cracks in structure. In reinforced concrete structures, the mix proportions of the materials of the concrete and aggregate type determine the compressive strength while the composite action of concrete and steel reinforcement supplies the flexural strength. In occasion of loss of stiffness, steel reinforcement no longer supports flexural stresses; concrete in turn is subjected to flexure. The compressive strength and flexural strength therefore play a crucial role. Effect of varying coarse aggregate size on the flexural and compressive strengths of concrete beam was investigated. Concrete cubes and beams were produced in accordance with BS 1881-108 (1983) and ASTM C293 with varying aggregate sizes 9.0mm, 13.2mm, 19mm, 25.0mm and 37.5mm, using a standard mould of internal dimension 150x150x150 for the concrete cubes and a mould of internal dimension of 150 x 150 x 750mm for the reinforced concrete beam. The water cement ratio was kept at 0.65 with a mix proportion of 1:2:4. The specimen produced were all subjected to curing in water for 28days and were all tested to determine the compressive strength and flexural strength using Universal Testing Machine. Compressive strength of cubes is 21.26N/mm2, 23.41N/mm2, 23.66N/mm2, and 24.31N/mm2 for coarse aggregate sizes 13.2mm, 19mm, 25.0mm and 37.5mm respectively. That of flexural strength of test beams is 4.93N/mm2, 4.78N/mm2, 4.53N/mm2, 4.49N/mm2, 4.40N/mm2 respectively. In conclusion, concrete to be used mostly to resist flexural stresses should be made of finer coarse aggregates.

Strengthening of reinforced concrete beam using steel fiber at different dept...eSAT Journals
Abstract
This paper presents the results of an experimental investigation for enhancing the shear and ultimate strength capacities of reinforced concrete (RC) beams using steel fiber at different depths. Ultimate loads, load-deflection curves, cracking and crushing patterns have been compared with those of the RC beams without steel fiber henceforth noted as controlled beam. A total of four sets of experiments each having three concrete beams, one set control beam and three sets with randomly distributed discrete steel fiber at different depths henceforth noted as fiber reinforced concrete (FRC) beam, were performed to determine the most economical structure in the perspective of ultimate strength and shear capacity. From the test results, it was found that incorporation of steel fiber in RC beams have shown to be effective in enhancing the shear strength capacity. It has also been observed that the strength increases with the use of varying depth of steel fiber. Beam strengthened using this scheme has shown 20% increase in shear strength and ultimate load in comparison to controlled beam.

Influence of reinforcement on the behavior of hollow concrete block masonry p...eSAT Journals
Abstract
Reinforced masonry was developed to exploit the strength potential of masonry and to solve its lack of tensile strength. Experimental
and analytical studies have been carried out to investigate the effect of reinforcement on the behavior of hollow concrete block
masonry prisms under compression and to predict ultimate failure compressive strength. In the numerical program, three dimensional
non-linear finite elements (FE) model based on the micro-modeling approach is developed for both unreinforced and reinforced
masonry prisms using ANSYS (14.5). The proposed FE model uses multi-linear stress-strain relationships to model the non-linear
behavior of hollow concrete block, mortar, and grout. Willam-Warnke’s five parameter failure theory has been adopted to model the
failure of masonry materials. The comparison of the numerical and experimental results indicates that the FE models can successfully
capture the highly nonlinear behavior of the physical specimens and accurately predict their strength and failure mechanisms.

MODELLING OF AN INFILL WALL FOR THE ANALYSIS OF A BUILDING FRAME SUBJECTED TO...IAEME Publication
In general the analysis of a building frame is carried out with a bare frame but the presence of masonry infill in a framed structure results in high stiffness and influence the distribution of lateral load and also the response of the framed buildings. It can be noted that there is a large variation of mechanical properties of bricks. Masonry, a combination of brick and mortar, behaves in a highly nonlinear manner. The infill panel needs to be modelled in the analysis of a structural frame subjected to lateral load to obtain its true behaviour. In order to model the masonry infill, its properties required. In order to determine the properties of brick masonry compression tests were conducted on masonry infill panels and prisms.

Experimental study of concrete using corrugated steel fibreAbishaY1
Concrete is one of the most versatile building materials.
▶ It can cast to fit any structural shape from a cylindrical water storage tank to a rectangular beam or column in a high rise building.
▶ The advantages of using concrete include high compressive strength, good fire resistance, high water resistance, low maintenance, and long service life.
▶ The disadvantages of using concrete include poor tensile strength low strain of fracture and formwork requirement.
▶ The major disadvantage is that concrete develops micro cracks during curing.
▶ It is the rapid propagation of these micro cracks under applied stress that is responsible for the low tensile strength of the materials, hence fibres are added to concrete to overcome these disadvantages.
▶ The addition of fibres in the matrix has many important effects. Most notable among the improved mechanical characteristics of fibre reinforced concrete (FRC) are its superior fracture strength, toughness, impact resistance, flexural strength resistance to fatigue, improving fatigue performance is one of the primary reason for the extensive use of steel fibre reinforced concrete(SFRC) in pavements, bridge decks, offshore structure and machine foundation.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

masonry to its full potential. Experimental study has been carried out to investigate the effect of reinforced masonry prisms on its
behavior in compression and effect of slenderness on the same. Mechanical properties of hollow blocks, mortar and grout were
investigated. Compressions testing of both unreinforced and reinforced masonry prisms were carried out. From the results, advantage
of reinforcing masonry and the effect of slenderness ratio is highlighted.

1. INTORDUCTION
Practice of masonry block work in buildings and civil
engineering structures has a long history going back to
centuries. Reinforced masonry also not being younger than
masonry dating back to 1813-1825, adopted to increase the
load bearing capacity of walls[1]. Due to the improvement in
the masonry materials, construction skills and reinforcement
techniques have improved the masonry construction from
massive load bearing structures to competitive and economical
with a bonus of thermal comforts.
Masonry buildings when subjected to lateral loads were found
to have earthquake related problems due to insufficient shear
and flexural capacity. With the development of reinforced
masonry by incorporating steel to provide with flexural and
tensile resistance. Especially for reinforcing hollow blocks
steel can be introduced to resist in-plane seismic forces of
earthquake. In the past few decades different ways of
reinforcing masonry techniques have been proposed, ensuring
ductility and energy dissipating capacity. The masonry
systems depend on various parameters like geometric shapes
and material of masonry unit, mortar, grout and amount of
steel and its detailing. Masonry has a promising future being
the most important construction material for buildings, schools
and other structures in the 21st century.
In this experimental program effect of reinforcing hollow
masonry prisms on compression capacity is studied by testing
both unreinforced masonry prisms and reinforced masonry
prisms. In addition a comparison is made on the effect of
slenderness on the compressive strength of both unreinforced
masonry prisms and reinforced masonry prisms.
2. EXPERIMENTAL PROGRAMME
Experimental investigation were carried out to arrive at the
following aspects:
(i) Compressive strength and stress-strain characteristics of
hollow concrete block, mortar and grout.
(ii) Compressive strength and stress-strain characteristics of
Unreinforced Masonry (URM) and Reinforced Masonry (RM
) prisms.
2.1 Hollow Concrete Blocks
For the proposed study hollow blocks of best available
strength were adopted from local standard manufacturers of
size 400 x 200 x190mm. The basic mechanical properties such
as dimensionality, dry density, water absorption were
conducted as per IS 2185 Part 1-1979[2], IRA was conducted
as per ASTM C67[3] and compression and stress-strain
characteristics were obtained by testing them in compression
testing machine. Mean values of dry density, water absorption,
IRA and compression were 2365.95 Kg/m3
, 3.2 %, 0.705 %
and 6.57 MPa respectively. The Young's modulus at 30% of
peak stress was found to be 14393.5 MPa.
2.2 Cement-Sand Mortar
Cement-sand mortar of 1:6 volume mix was adopted in this
investigation. Grade 53 ordinary port land cement conforming
to IS 2250-1981[4] and river sand from a local source was

used. Consistency of mortar was obtained by performing flow
table test according to IS 5512-1969[5] and water-cement ratio
of 1.26 was adopted for 100% flow. Compressive strength of
mortar was obtained by testing mortar cubes of 5cm and the
mean compressive strength obtained was 6.3 MPa. The
modulus of mortar was taken from stress-strain relationship
obtained by compression testing of prisms of 150 x 150 x 300
and the young`s modulus at 30% peak stress was found to be
10222.54 MPa.
2.3 Grout
Grout is a filler material used to fill the cells in hollow blocks
to increase its strength and hold the steel in its desirable
position. Grout adopted for masonry prisms was of high slump
mixture of cement, aggregate, water. To arrive at the water-
cement ratio for a desirable slump of 200 to 250mm[6], slump
test was carried out. M20 grade concrete of maximum size of
aggregate 12.5mm, with a slump of 210mm was used as grout
with water-cement ratio of 0.75 as obtained in slump test. The
compressive strength of grout was obtained by compression
test of grout concrete cube of 150mm. The mean compressive
strength was obtained as 26MPa. The modulus of grout was
taken from stress-strain relationship obtained by compression
testing of cylinders of 150 diameter x 300 and the young`s
modulus at 30% peak stress was found to be 29527 MPa.
2.4 Reinforcement
Reinforcement in masonry is adopted to increase shear and
tensile stress resisting capacity, axial load carrying capacity
for various load conditions and inducing ductility to resist
seismic loads. In this investigation reinforcement was
provided as per guidelines of IITK-GSDMA[7]. Providing
with 0.56% steel, Grade Fe 415 reinforcing bars of 12mm
diameter was provided at all four corner of the block as
longitudinal reinforcement and supported by stirrups of 8mm
diameter holding all four bars as lateral reinforcement.
2.5 Compressive Strength of Masonry Prisms
Masonry prisms are obtained when the hollow blocks are stack
bonded one above the other. In this experimental programme
compressive strength of stack bonded masonry prism of 5
block height were cast. Both URM and RM prisms of hollow
concrete blocks with 10mm mortar joint were cast and cured
under moist gunny bags.
3. CASTING AND TESTING
Compressive strength of masonry was determined by testing
the stack bonded masonry prisms. Five block height stack
bonded masonry prism were casted using 200 mm hollow
concrete blocks and cement-sand mortar(1:6) as shown in fig
3(a). Prisms of size 400 x 200 x 990mm with a joint thickness
of 10 mm were used. Further prisms were prepared with
reinforcement for examining the influence of reinforcement on
masonry compressive strength. Fe-415 grade reinforcing bars
of diameter 12 mm and 8 mm were used and 53 grade of
ordinary Portland cement was used as shown in fig 3(e).
Testing of four of each URM and RM prisms were carried out
on Testing floor with 1000KN capacity hydraulic jack,100mm
bearing plate and demec gauge of least count of 0.001 for
measuring deformation across the mortar joint.
Testing of URM prisms was done as shown in fig 3(b) and the
crack, failure pattern was observed as shown in fig 3(c),3(d).
Testing of RM prisms was done as shown in fig 3(f) and the
crack, failure pattern was observed as shown in fig 3(g).

4. RESULTS AND DISCUSSION
The mean compressive strength of URM and RM prisms were
obtained to be 4.21 and 8.02 MPa respectively as shown in
table 1.
The modulus of URM and RM prisms was obtained from their
respective stress-strain relationship. The modulus of URM
and RM prism were found to be 4545 and 10199 MPa
respectively shown in plot 1 and plot 2. The above results
shows that reinforcing the masonry prisms with 0.56% steel
the increase in compressive strength was found to be 90.5% of
that of URM.
The results also shows that the increase in modulus of
elasticity is 2.24 times of URM for RM prism.
Effect of slenderness on the compressive strength was studied
by comparing the results of 3 block height prism[8] and 5
block height prism. Comparison is shown in table 2. From the
results it is observed that the compressive strength of masonry
reduces with increase in slenderness ratio.

5 .CONCLUSIONS AND REMARKS
1. Reinforcing of masonry prisms increases the axial
compression load capacity, encouraging to be used in load
bearing structures.
2. Effect of increase in slenderness ratio on compression
strength should result in reduction of compression strength.
The investigation showed that the reduction was only marginal
of 0.3 MPa. A possible explanation for this result could be
because of variation in the mechanical properties of the
masonry components such as compressive strength of unit
blocks, mortar, grout, quality of river sand etc.. Which cannot
be humanly controlled.
3. Masonry behavior being complex involving several
variation factors, it is recommended that more investigation
involving 3,4,5 block height masonry prisms is needed to be
carried out to arrive at a fair conclusion.
