Book excerpt: Expansive soils exhibit substantial swelling and shrinkage due to moisture content fluctuations. Predicting this volume change behavior of expansive soils has been a major challenge to the engineers in the past few years. One of the factors which play a vital role in understanding the behavior of the expansive soils is mineralogy. Chittoori (2008) had developed three models to quantify the clay minerals using Microsoft Excel Solver, Regression Equations and Artificial Neural networks. The previous models have only considered clay fraction, i.e. montmorillonite, kaolinite and illite. But the non-clay mineral contents like quartz and feldspar were not taken into consideration. Hence the main objective of this research is to include the quantification of both non-clay and clay minerals present in the soil. Also, the inclusion of potassium from feldspar and how it impacts clay mineralogy are studied. In order to accomplish this research objective, seventeen natural soils samples were taken with different mineralogical contents. Basic soil classification tests like hydrometer, wet sieve analysis were performed on these soils to identify the type of soil and for the separation of silt and clay fraction along with greater than 75 microns samples. Mineralogy studies on the test soils include Cation exchange capacity (CEC), Specific Surface Area (SSA) and Total Potassium (TP). The results from these tests were analyzed using the regression model developed by Chittoori (2008) and also by the modified method which identifies the mineral feldspar and quartz. Results from both the methods were compared and the percent amount of minerals, kaolinite and illite has shown considerable change in the predicted percentages. This research paves way for future research studies to increase the accuracy of the mineral quantification process by quantifying the percentages of both the clay and non-clay minerals present in the soils, which in turn will provide better understanding of the expansive behavior of natural soils.
Book Synopsis Detection and Quantification of Expansive Clay Minerals in Geologically-Diverse Texas Road Aggregate Fines by : George Andrew Russell

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Expansive clay mineral contamination of road aggregate materials in Texas is a persistent problem. Hydrous layer silicate minerals - particularly smectites - in concretes are associated with decreased strength and durability in Portland cement and asphalt concretes. The Texas Department of Transportation (TXDOT) and Texas A&M Transportation Institute (TTI) evaluated the methylene blue adsorption test for its potential to identify and estimate quantities of expansive clays in aggregate stockpiles. Clay mineral quantification was completed for 27 geologically-diverse aggregate materials from Texas, Oklahoma, and Arkansas. X-ray diffraction analysis (XRD) of separated clays on glass was conducted, and NEWMOD was utilized to model the resulting diffraction patterns. Methylene blue adsorption (MBA) and cation exchange capacity (CEC) of clay fractions (

Book Synopsis Clays and Clay Minerals by : S. W. Bailey
Download or read book Clays and Clay Minerals written by S. W. Bailey and published by Elsevier. This book was released on 2013-10-22 with total page 491 pages. Available in PDF, EPUB and Kindle. Book excerpt: Clays and Clay Minerals documents the proceedings of the 14th National Conference in Berkeley, California. This book focuses on the structure and quantitative analysis, surface reactivity, genesis, and synthesis of clays and clay minerals. Topics discussed include status of clay mineral structures; layer charge relations in clay minerals of micaceous soils and sediments; mechanical force fields in a clay mineral particle system; and kinetics of decomposition of cobalt coordination complexes on montmorillonite surfaces. The factors affecting the frequency distribution of clay minerals in soils; stability of brucite in the weathering zone of the new Idria serpentinite; and interrelationships of physical and chemical properties of kaolinites are also elaborated in this publication. This compilation is beneficial to students and researchers conducting work on clay mineral studies.

Download or read book Clay Minerals written by B. Velde and published by Elsevier. This book was released on 2000-04-01 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book follows another by the same author, published in 1977, which the author considered as ``a first attempt to put some order in the house of clay petrology''. That book was described as ``an excellent first attack on clay mineral petrology... informative, and stimulating because of the method of presentation and the open-door treatment of the subject. Not only clay-mineral scientists but petrologists in general must read this first book on clay mineral petrology.'' (Earth Science Reviews).This book describes clay mineral occurrence in terms of the physical and chemical forces which influence it. It includes a geological description of mineral occurrence, a definition of the major features of clay mineral chemical composition, and an indication of the physical-chemical boundaries of these occurrences. It also presents general patterns for the geological environments of weathering, sedimentation, burial diagenesis, deep sea basalt alteration, hydrothermal alteration of acidic rocks and chemical precipitation in acidic and basic environments. The major clay groups are related to one another as they occur in geological systems through the use of graphical analysis. The author has thoroughly reviewed the relevant literature for the last 25 years. The data and analyses obtained and presented in this book will not only make interesting reading, but will also prove extremely useful to those involved with studies in deep sea research, mining geology, petroleum geology, agronomy and civil engineering.
