This document summarizes a study on using plastic as a soil stabilizer. Standard Proctor compaction tests were conducted on lateritic soil mixed with varying percentages of cut plastic strips. California Bearing Ratio (CBR) tests found that adding 0.4% plastic strips improved the 4-day soaked CBR value of the soil. Plate load tests also showed increased shear strength and load capacity with the addition of plastic. The results indicate that using plastic waste can enhance soil properties for road construction and provide an effective way to reuse non-degradable waste.
This presentation includes in how many ways plastic can be used in soil stabilization. It covers how a waste material can be used without any additional increase in cost.
Soil stabilization can be done in many ways. But the stabilization using waste plastic fibers is an economic method since the stabilizer used here is waste plastic materials, which are easily available. A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable.

An Experimental Study of Soil Stabilization with Cement and Polymerijtsrd
The aim of the study was to determine the value of Unconfined compressive strength and CBR values of Soil after stabilizing it with Cement and Polymer. Soil stabilization has been widely used as an alternative to substitute the lack of suitable material on site. The utilization of nontraditional compound stabilizers in soil improvement is developing every day. In this investigation a lab try was led to assess the impacts of waterborne polymer on unconfined pressure quality on sandy soil and CBR Test on clayey soil .The lab tests were performed including grain size of sandy soil, unit weight, and unconfined compressive quality test. The sand and different measures of polymer 2 , 3 , and 4 and concrete 20 , 30 , and 40 were blended in with every one of them into mixture utilizing hand blending in research center conditions. The examples were exposed to unconfined pressure tests to decide their quality following 7 days of restoring. The consequences of the tests showed that the waterborne polymer fundamentally improved the unconfined pressure quality of sandy soils which have weakness of liquefaction. Polymer altered the building properties of soil through physical holding. The amount of polymer required to modify the engineering properties was directly related to specific surface and soil particle coating thickness. Polymer amended soils displayed a reduced performance compared to cement amended soils.

soil stabilization using burnt municipal solid waste ash is done with varied test being carried out on different proportions of soil and additive which in our case is bottom ash and not fly ash
As a project in undergraduate college, we decided to explore soil and ways to reinforce using plastic fibers. Our study included Geo synthetic meshes as well as chemical stabilizers. Our scope of study study was finalized to be Waste Plastic Fiber Reinforced soil, as plastic was being used experimentally in small projects while waste plastic is easily available.
Overview of Soil Stabilization :Cement / Lime :PPTAniket Pateriya
Soil-cement is frequently used as a construction material for pipe bedding, slope protection, and road construction as a sub-base layer reinforcing and protecting the subgrade. It has good compressive and shear strength, but is brittle and has low tensile strength, so it is prone to forming cracks.
Lime can be used to treat soils to varying degrees, depending upon the objective. The least amount of treatment is used to dry and temporarily modify soils. Such treatment produces a working platform for construction or temporary roads. A greater degree of treatment supported by testing, design, and proper construction techniques--produces permanent structural stabilization of soils.
A highway pavement is a structure consisting of superimposed layers of processed materials above the natural soil sub-grade, whose primary function is to distribute the applied vehicle loads to the sub-grade. The pavement structure should be able to provide a surface of acceptable riding quality, adequate skid resistance, favorable light reflecting characteristics, and low noise pollution.

Stabilization is the process of blending and mixing materials with a soil to improve certain properties of the soil. The process may include the blending of soils to achieve a desired gradation or the mixing of commercially available additives that may alter the gradation, texture or plasticity, or act as a binder for cementation of the soil.

Utilisation of Waste Materials in the Construction Of RoadsIJERD Editor
Expansive soils are so widely spread that it becomes impossible to avoid them for highway construction to keep the network structure for mobility and accessibility. These soils are prevalent as large tracts in many parts of the world. Many highway agencies, private organizations and researchers are doing extensive studies on waste materials and research projects concerning the feasibility and environmental suitability. It is necessary to utilize the waste affectively with technical development in each field. Cyclic plate load tests were carried out on the tracks with optimum percentage of reinforcement materials like waste plastics and waste tyre rubber in gravel/flyash subbase laid on expansive subgrade. Test results show that maximum load carrying capacity associated with less value of rebound deflection is obtained for gravel/flyash reinforced subbase compared to unreinforced subbase.
Strength Behaviour of Expansive Soil Treated with Tile WasteIJERD Editor
The amount of wastes has increased year by year and the disposal becomes a serious problem. This
paper presents the effects of tile waste on, liquid limit, plastic limit, compaction characteristics, California
Bearing Ratio and swelling pressure of an expansive soil. The expansive soil collected locally was mixed with
tile waste from 0 to 30% at an increment of 10%. From the analysis of test results it was found that, liquid limit,
plastic limit, optimum moisture content, and swelling pressure are decreased, maximum dry density and
California bearing ratio are increased with an increase in tile waste.

Abstract
Road improvement is one of the significant parts of developing foundation which is growing at a quick rate; the development of roads is of real concern in India as it elevates access to monetary and social administrations, creating horticultural income and productivity employment. In India the greatest impediment to give a complete system of road framework is the constrained funds accessible to build road by the conventional method. The nearby accessible soil is not satisfactory for supporting the reiteration of high business vehicles on consistent road width results into weakening of roads. Clay soils change fundamentally in volume with change in water substance are the reason for distortions to structures that incurs cost taxpayers several billion rupees every year in the India. This paper manages a research facility examination of soil as CL as per Indian Standard (1498 – 1970). To the untreated soil adjustments utilizing the doses of 1 and 2 % PPC are carried out. At first the tests are directed to focus physical & engineering properties of natural soil by directing research center tests furthermore to assess the change in properties by the addition of stabilizers to be utilized as a part of pavement design for economy.
Keywords: Cement, Soil Stabilization, strength, moisture content.
Soil stabilization is the permanent physical and chemical alteration of soils to enhance their physical properties.
Stabilization can increase the shear strength of a soil and control the shrink-swell properties of a soil, thus improving the load-bearing capacity of a sub-grade to support pavements and foundations.
Stabilization can be used to treat a wide range of sub-grade materials from expansive clays to granular materials.
Stabilization can be achieved with a variety of chemical additives including lime, fly ash, and Portland cement, as well as by-products such as lime-kiln dust and cement-kiln dust.
1) Mechanical Soil Stabilization Technique:
Dense and well graded material can be achieved by mixing and compacting two or more soils of different grades.
Addition of a small amount of fine materials such as silts or clays enables binding of the non-cohesive soils which increases strength of the material.
Factors affecting the mechanical stability of mixed soil may include:
The mechanical strength and purity of the constituent materials
The percentage of materials and its gradation in the mix
The degree of soil binding taking place
The mixing, rolling, and compaction procedures adopted in the field
The environmental and climatic conditions
2) Compaction Soil Stabilisation Technique:
Uses mechanical means for expulsion of air voids within the soil mass resulting in soil that can bear load subsequently without further immediate compression.
Dynamic compaction is one of the major types of soil stabilization; in this procedure, a heavyweight is dropped repeatedly onto the ground at regular intervals to quite literally pound out deformities and ensure a uniformly packed surface.
1) Moisture Content. 2) Specific gravity of soil. 3) Atterberg’s limit. 4) Liquid limit. 5) Particle size distribution. 6) Preparation of reinforced soil sample. 7) Determination of shear strength.
1) Moisture Content
Soil tests natural moisture content of the soil is to be determined. The natural water content also called the natural moisture content is the ratio of the weight of water to the weight of the solids in a given mass of soil.
2) Specific gravity of soil.
The specific gravity of soil is defined as the unit weight of the soil mass divided by the unit weight of distilled water at 4°C.
3) Atterberg’s limit
Atterberg's limits are a set of tests used in soil mechanics to determine the plasticity and compressibility characteristics of soil
1. It improves the strength of the soil, thus, increasing the soil bearing capacity.
2. It is a lot of economical each in terms of price and energy to extend.
3. Bearing capacity of the soil instead of going for deep foundation or raft foundation.
4. It offers more stability to the soil in slopes or other such places.
5. Sometimes soil stabilization is also stop soil erosion or formation of mud, which is extremely helpful particularly in dry and arid weather.

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.
Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
