This document summarizes research on using scrap tire rubber to partially replace aggregates in concrete. It reviews studies that investigated the effect on properties like workability, compressive strength, tensile strength, and flexural strength. The main findings are:
1) Workability decreases as the percentage of rubber increases due to its non-polar nature, but can be improved with superplasticizers.
2) Compressive, tensile and flexural strengths all generally decrease as the percentage of rubber replacement increases, due to weak bonding between rubber and cement paste.
3) Pretreatment methods like using NaOH can improve the bonding and lead to higher strengths in some cases.
4) Rubber concrete may be

This report presents a study on the effect of partial replacement of coarse aggregates by rubber tyre aggregates on the property of concrete. Utilizing the waste rubber tyers in the form of aggregates as reinforcement in the concrete solve the problem of disposing the waste and increase the flexural strength of concrete. Different tests were conducted on the concrete with varying percentage of rubber tyre aggregates and comparing those results with normal concrete. Data presented includes workability, compressive strength, split tensile strength, flexure tensile strength and flexibility. This report describes an experimental study on mixing rubber aggregates with concrete at different mixing ratios (0, 5, 10, and 15) % by weight of coarse aggregates. The tests conducted were workability, compressive strength, split tensile strength, flexure tensile strength. Though there is decrease in compressive strength, workability, split tensile strength, flexural strength and flexibility get increased.

Fundamental properties of self compacting concrete utilizing waste rubber tir...eSAT Journals
Abstract
Utilization of waste rubber tires in concrete technology is a popular research topic over the last two decades. Reuse of waste
rubber tires in self-compacting concrete leads sustainable construction. Several studies have been conducted on incorporation of
waste rubber tires in self-compacting concrete (SCC). This review paper draws general conclusions on fundamental properties of
SCC by summarising and comparing many independent research works and justifies weather these waste tire aggregates are
possible to utilize in self-compacting concrete or not . From the review it is evident that the waste rubber tire aggregates can be
used in SCC as partial replacement of both coarse aggregates and fine aggregates. The result Although the mechanical properties
of SCC experiences negative effect for introduction of waste rubber tire aggregates, still performance of rubberized SCC is better
than ordinary SCC. Fresh properties of SCC incorporating rubber tire aggregates also is in acceptable limit.

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.
