This document presents the results of an experimental study on Slurry Infiltrated Fibre Concrete (SIFCON) using manufactured sand (M-sand) and partially replacing cement with silica fume. Various tests were conducted to evaluate the mechanical properties of SIFCON specimens containing 4%, 6%, 8%, and 10% steel fibers. The results show that compressive, tensile, and flexural strengths generally increased with higher fiber content up to 8%, above which the strengths decreased due to poor bonding. Non-destructive tests found rebound number and pulse velocity were highest for 8% fiber content, confirming 8% as the optimum amount. The study demonstrates that M-sand and silica fume can be used to

Incorporation of fibers further enhances its properties specially related to post crack behavior of SCC. The fibers used in the study are 12 mm long chopped glass fiber and carbon fiber. The volume fraction of fiber taken is 0%, 0.1%, 0.15%, 0.2%. The project comprised of two stages.
A review of the effect of basalt fibre lengths and proportions on the mechani...eSAT Journals
Abstract
During the past few decades, the concrete construction field has seen a growing interest in the advantages that fibre reinforcement has to offer. Between the different types of fibres available, basalt fibre is considered a promising new material to use. It has extremely good strength characteristics and thermal resistance, high resistance to an alkaline environment, and is cheap product, making it an excellent material to reinforce concrete. In view of the significance of basalt fibres for concrete, and because different lengths and proportions of basalt fibres have an effect on the mechanical properties of concrete, it is proposed to review the effect of using different basalt fibre lengths and content on the mechanical properties of concrete. The mechanical properties of concrete reviewed are compressive strength, tensile strength, flexural strength, permeability, workability, and unit weight. This paper has for the first time reviewed the current literature related to the effect of using basalt fibres of different proportions on the mechanical properties of concrete, provided future researchers with the information and facts needed to compare their work, and identified the best basalt fibre length and content combination that demonstrates an improvement in the mechanical properties of concrete. From reviewing the literature, it was found that most authors agreed that the mechanical properties of concrete improved significantly when using basalt fibres with a length between 12mm and 24mm, and content between 0.1% - 0.5% by total volume. In this context, the length and content of basalt fibres in concrete becomes an important parameter for the mechanical properties of concrete.
Keywords: Basalt Fibres, Compressive Strength, Tensile Strength, Flexural Strength, Elastic Modulus, Workability, Permeability, Unit Weight.

Hence, it can be concluded concrete prepared with 3% NS and 6%
SF combination can be recommended for the structural applications. The increase in the strength
properties of concrete is due to the availability of additional binder in the presence of NS and SF.
The improved durability property of concrete is due to proper packing of NS and SF particles results
in reduction in voids and leading to dense concrete.
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!

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
