Experimental Study on Concrete with Waste Granite Powder as an AdmixtureIJERA Editor
Granite fines which are the byproduct produced in granite factories while cutting huge granite rocks to the desired shapes. Granite fines are used as a filler material in the concrete, replacing the fine aggregate which will help in filling up the pores in the concrete. Filling up of the pores by granite fines increase the strength of the concrete and also a material which is abundantly to investigate the strength behavior of concrete with use of granite fines as an additive. Concrete is prepared with granite fines as a replacement of fine concrete in 4 different propositions namely 2.5%, 5%, 7.5% and 10% and various tests such as compressive strength, split tensile strength and flexural strength are investigated and these values are compared with the conventional concrete without the granite fines. It was observed that substitution of 7.5% of cement by weight with Granite fines in concrete resulted in an increase in compressive strength for both 7 & 28 days to 33.14 & 43.40 N/mm2 compared to 23.26 & 39.41 N/mm2 of conventional concrete. Tensile strength too followed a similar pattern with a 7.5% substitution with granite fines increasing the tensile strength for 7 & 28 days to 2.87 &4.19 N/mm2 compared with a 2.4 & 3.4 N/mm2 of conventional concrete. However flexure strength of 7.5% granite fine replacement exhibited a good improvement of flexural strength for 28 days to 6.34 N/mm2compared to a 3.35 N/mm2 of conventional concrete. Further investigations revealed that to attain the same strength of conventional concrete a 10% substitution with granite fines is effective. So it can be concluded that when locally available granite is a good partial substitute to concrete and improves compressive, tensile and flexure characteristics of concrete, while simultaneously offsetting the overall cost of concrete substantially.

A PARAMETRIC STUDY ON EFFECT OF FLY ASH TOGETHER WITH FIBER FOR SUSTAINABLE C...IAEME Publication
The present challenge for civil engineers is to produce high volume and high
performance fly ash concrete with increased durability and service life, at lowest
possible cost. Also concrete produced should have minimal negative impact on the
environment, which is green and sustainable concrete. This can be achieved by
reducing the use of natural lime, fine and coarse aggregates whose resources are
limited and are depleting very fast day by day. It could also be achieved by utilizing
maximum possible industrial by-product like fly ash in concrete as it would reduce
landfill area for fly ash disposal and CO2 emission during cement manufacturing
process. Effect of fly ash as replacement of cement together with fibers in concrete on
durability is very well reported in literatures. However effect of fly ash as partial
replacement of cement and sand together with fibers is not clearly available in
literatures. Literatures show that partial replacement of cement by fly ash reduces early
age strength of concrete. Partial replacement of sand by fly ash together with fiber shall
compensate strength loss due to partial replacement of cement by fly ash. Due to
government restrictions on natural sand mining from river beds, contractors are
demanding a reliable and all weather partial or full replacement material for sand.
Present study shall be a right step forward in reducing consumption of natural sand
and consuming higher volumes of fly ash available in Chhattisgarh region together with
fibers for sustainable and durable concrete.

It is observed that at 20% of stone dust and brick dust is the optimum dosages for concrete mixture.
Self compacting concrete for slip form pavingeSAT Journals
Abstract Slip form paving has been extensively used worldwide for construction of pavements. During the process of paving, concrete mix with a slump less than 50 mm is placed in front of a paver. Because of the low consistency of the mix, a great deal of vibration is needed to move entrapped air and compact the concrete. There is a need to overcome problem by designing a concrete that would not require vibration to compact the concrete mix, at the same time stability after extrusion and high flexural strength. Mix design based on the absolute volume concept was adopted to fabricate SFSCC. Volume of paste of 0.38 and water content of 200 kg/m3 was kept constant throughout the study. Cement content was varied from 360 to 425 kg/m3, 3 mixes of SCC with GGBS (SFSCC-S), 3 mixes of SCC with 2% of alccofine replaced by cement (SFSCC-SA) and 3 mixes of SCC with 2% of metakaolin replaced by cement (SFSCC-SM) is reported. The quantity of polypropylene fibers used in all the mixes was 900 gm/m3. Slump, spread, green strength and compaction factor were evaluated for all the 9 mixes. To simulate the practical construction process, a mini paver system was fabricated. The strength parameters compressive and flexural strength of concrete was evaluated at 7 days and 28 days.

Use of Granite Waste as Partial Substitute to Cement in ConcreteIJERA Editor
With the ever increasing cost of construction materials there is a need to curtail the same by using cheaper substitutes. In this investigation Granite Slurry (GS) was used as partial substitute in proportions varying from 5% to 20% by weight to cement in concrete and tested for compressive strength, tensile strength and flexure strength. It was observed that substitution of 10% of cement by weight with GS in concrete resulted in an increase in compressive strength to 48 N/mm2 compared to 35 N/mm2 of conventional concrete. Tensile strength too followed a similar pattern with a 10% substitution with GS increasing the tensile strength to 3.6N/mm2 compared with a 2.4 N/mm2 of conventional concrete. However flexure strength of 10% GS replacement exhibited a good improvement of flexural strength to 4.6 N/mm2compared to a 3.2 N/mm2 of conventional concrete. Further investigations revealed that to attain the same strength of conventional concrete a 20% substitution with GS is effective. So it can be concluded that when locally available GS is a good partial substitute to concrete and improves compressive, tensile and flexure characteristics of concrete, while simultaneously offsetting the overall cost of concrete substantially.
EFFECT ON STRENGTH AND DURABILITY PROPERTIES OF CONCRETE INCORPORATING GRANIT...IAEME Publication
An enormous amount of stone dust is produced as a sluggish waste material from the marble and granite stone industry and various operations of stones. It has become a serious problem to the society and environment. Presently, use of river sand confirming to IS 383-1970 has become difficult because of unavailability and costly due to environmental rules and regulations. To overcome this difficulty, an economical alternative can be developed by partial replacement of sand with granite quarry dust (GD) and cement with marble powder (MP) in concrete. In this paper, a study is conducted to investigate the viable use of marble granite residue (MGR) in concrete mixes. Sand is replaced with GD along with cement (OPC grade 43) is replaced with MP as 0%, 10%, 20%, 30% & 40% by weight for M25 grade of concrete. To study strength and durability properties of concrete, test on fresh and hardened concrete are conducted for all the mixes. The results show that MGR assimilation results enhancements in the compressive strengths of concrete by replacement up to 20% of GD and 10% of MP without affecting significant characteristics of the mix.
Analysis on concrete made from over burned bricksIJARIIT
Concrete is a composite material used for the ground that all considerate designing structure is developed with concrete
in an efforts to find an alternative material in concrete much work has been focused to use brick aggregates in producing normal
strength or even higher strength by far the most common course aggregates used in concrete is obtained from natural rock, but
type of rock suitable for concrete making is not available locally and everywhere. However, there is hardly any literature
producing previous concrete using bricks chips as course aggregates. The research was conducted to study the suitability crushed
over burnt bricks as alternative course aggregates for concrete production. The concrete cube beams and cylinders of M-25, M-
30, and M-35 grade were thrown in this trail explore work and try to analyze different properties of concrete with crushed over
burnt bricks as an alternative material. The physical properties like compressive strength, tensile strength, flexural strength and
workability with alternative material was used with a dosage of 10%, 20% and 30% in concrete with the age of 7, 14, 28 and 50
days of curing. The general properties of fresh and hardened concrete were tried and the outcomes were dissected. Over Burnt
bricks were casted and tested for compressive strength, tensile strength, flexural strength, and workability. The result shows that
the aggregate that concrete derived from Over Burnt bricks aggregate attained lower strength than the regular concrete. More
detailed and elaborated work is recommended with different mix ratio and a different proportion of Over Burnt aggregates for
a better conclusion.

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!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
