This document analyzes the behavior of fly ash when stabilized with lime and Recron 3s fiber for use in landfills. Tests were performed on fly ash alone and in combination with lime and fibers to determine the optimum amounts for maximum strength. A vane shear test was used to measure the shear strength of the mixtures. The results found that adding lime up to 15-20% and Recron fibers up to 3% increased the shear strength of the fly ash. Therefore, fly ash stabilized with lime and fibers can potentially be used in landfills and as fill material.

A review on stabilization of soil using bio enzymeeSAT Journals
Abstract In developing countries like India the most important requirement of any project after performance criteria is its economical feasibility and serviceability criteria. The conventional methods are time consuming and are not economically feasible. Hence there is a need to discover the other possible ways to satisfy the performance as well as economical criteria. In this paper, popularly available bio-enzymes and their effect on engineering properties of soil are discussed. The stabilization of soil with bio-enzyme is a revolutionary technique which becoming popular worldwide. Recently there are many bio-enzymes available for soil stabilization such as renolith, Perma-Zyme, Terra-Zyme, Fujibeton etc. These enzymes have been proven to be very effective and economical. Another advantage of the bio-enzyme is that these are environment friendly. When these bio-enzymes are mixed with soil they alter its engineering properties. Their efficiency depends upon the amount of dose, type of soil available and field conditions. The use of bioenzyme in soil stabilization is not very popular due to lack of awareness between engineers and non availability of standardized data. However, recently some bio-enzyme stabilized roads were constructed in various parts of India, which are performing very well. Keywords: Bio Enzyme, Nontraditional Soil Stabilizer.
This study used eco-friendly materials known as Periwinkle Shell Powder (PSP) in
stabilizing the engineering properties of lateritic soil. Preliminary test was performed
on the un-stabilized lateritic soil for the purposes of identification and classification
(natural moisture content, liquid limits, plastic limits, and plasticity index). The
engineering tests were conducted on the lateritic soil stabilized with additions of (2, 4,
6, 8 and 10 %) PSP and OPC respectively. The result showed that cement gave a
progressive increase in the Maximum Dry Density (MDD) of the lateritic soil from
1875 kg/m3 (2 %) to 2294 kg/m3 (10 %) respectively. This represents 22 % increase
in the MDD from the un-stabilized state. For PSP, the Maximum MDD was attained at
6 % (1974 kg/m3), representing 5.3 % increase in MDD of the soil from the unstabilized
state. For both stabilizing agent, the Optimum Moisture Content (OMC)
increases from 13.65 % to 13.83 % and from 11.72 % to 14.41 % for Cement and
Periwinkle Shell Powder respectively. PSP recorded an increase of 5.6 % of CBR
value compared with OPC that recorded an increase of 34 % CBR value. The study
therefore concluded that Periwinkle Shell Powder (PSP) could be considered as good
stabilizer for clayey or lateritic, and its uses as a stabilizer could also provide a big
relief to the environmental pollution caused by its indiscriminate dumping

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.
