Date Created: 2017
Subjects--Topical: Civil engineering, Environmental engineering
Description: In 2014 approximately 47% of the 190 million short tons of coal combustion product (CCP) was recycled. As a construction material, coal fly ash (CFA) finds considerable use as a partial replacement for Portland cement, as structural fill, and as a...

Title: Geotechnical Controls on Organo-Silane Modification of Soils and Coal Combustion Fly Ash
Author: Keatts, Matthew
Date Created: 2014
Subjects--Topical: Civil engineering, Geotechnical engineering
Description: Organo-silane (OS) surface modification works by chemically altering the surface of silica based materials and rendering them hydrophobic (waterproof). Limited research is present in the literature addressing the use of OS modified soils as an inf...

Title: LABORATORY EVALUATION OF THE UNCONFINED COMPRESSION STRENGTH OF POLYMERIC FIBER REINFORCED SOILS
Author: Kral, Robert
Date Created: 2014
Subjects--Topical: Civil engineering, Soil science, Geotechnical engineering
Description: Geosynthetic fiber reinforced soil can be used to remediate weak, near-surface soils. The purpose of this study was to determine the impact that the geofibers had on the unconfined compressive strength (UCS) of various soil types. To distinguish t...

Title: Mobilization of oxyanion forming trace elements from fly ash based geopolymer concrete
Author: Sanusi, Olanrewaju
Date Created: 2012
Subjects--Topical: Environmental engineering
Description: The suitability of fly ash based geopolymer concrete as a replacement for ordinary Portland cement (OPC) concrete depends on the mobility of elements from the material. Due to the alkaline nature of geopolymer concrete, there is a potential for th...

Title: FINITE ELEMENT STUDIES OF ORTHOGONAL MACHINING OF ALUMINUM ALLOY A2024-T351
Author: Patel, Jaimeen
Date Created: 2018
Subjects--Topical: Mechanical engineering, Mechanics
Description: In this work, a new machining model using the commercial finite element software ABAQUS is developed. The model regards material separation, chip serration and breakage as ductile fracture processes where energy is required to form new surfaces. T...

Title: A discrete element approach to predicting the uniaxial compressive response of plain concrete
Author: Tannu, Nakul
Date Created: 2017
Subjects--Topical: Mechanical engineering
Description: Discrete element method (DEM) has become the method of choice for modeling the mechanical response of materials with granular structure. The method consists of representing the material as a collection of particles that interact with each other by...

Title: A study of surface modification effect of hemp fibers on the bulk material properties of hemp-poly (lactic acid) composites: thermal stability, mechanical, therm0-mechanical and biodegradability
Author: Oza, Shubhashini
Date Created: 2013
Subjects--Topical: Civil engineering, Sustainability, Environmental engineering
Description: Biocomposites made with, natural fiber and bio-based polymers, have many advantages over their synthetic counterparts including low cost, low density, high strength and biodegradability. However, some biocomposites can present problems due to high...

Title: POST-LAST GLACIAL MAXIMUM LANDSCAPE EVOLUTION OF THE UPPER CONEJOS RIVER BASIN, SAN JUAN MOUNTAINS, CO, USA.
Author: Aldred, Jennifer
Date Created: 2020
Subjects--Topical: Geomorphology, Geology, Soil science
Description: Soil development combined with sediment storage and erosion in small, upland watersheds are key landscape processes for which assumptions are frequently made but rarely verified in landscape evolution studies. However, processes such as these, act...

Title: Optimal variable speed limit control for mixed traffic flows in a connected and autonomous vehicle environment
Author: Yu, Miao
