Improved Techniques For Washing Iron Blue Suspensions : Ii. The Preparation Of O, O'-Dichlorobenzidine From O-Chloronitrobenzene., Marvin L. Gernert

Electronic Theses and Dissertations

I. IMPROVED TECHNIQUES FOR WASHING IRON BLUE SUSPENSIONS

The investigation of several procedures for the speeding of the washing of iron blue suspensions to remove electrolytes is reported. The use of several techniques to coagulate blue particles in the colloidal range to cause more rapid settling was found to be of little value. A conventional Oliver filter and centrifugal clarifier were found to be unsatisfactory for clearing iron blue suspensions. Considerable advantage in washing by settling and decantation was obtained with the settling of the blue suspensions in relatively shallow vessels. A continuous washing procedure was developed whereby the blue …

A Summary Of Experiments With Air Entrainment In Cement Concrete, Kentucky Highway Materials Research Laboratory

Kentucky Transportation Center Research Report

Field and laboratory experiments designed to show the merits of air-entrainment in cement concrete have been conducted by the Department of Highways since 1940. During that time six laboratory projects with many variables have been completed, and most of these were directly related to the four experimental roads which have been in service from four to six years. Collectively these experiments form a moderately comprehensive analysis of the features of air-entrainment, still there are many points which have not been fully covered either because of limitations in time and personnel or because of new developments which render some of the …

Porous Backfill, Robert F. Baker

Kentucky Transportation Center Research Report

Until the late 1930's, the accepted practice for the construction of drainage installation included the use of a large, approximately No. 2 size, aggregate as porous backfill. However, a lage number of drains ceased to function as result of clogging or "silting"*, and many highway departments practically eliminated sub-surface and intercepting drainage.

The following report summarizes some of the more important studies that have dealt with "filter" (backfill material) to be used in drainage construction. The scope of it is limited, dealing primarily with the questions of proper gradation.

At present Kentucky Specifications (1) require that the gradations of the …

A Preliminary Investigation Of The Hydrometallurgy Of Philipsburg Manganese, W. L. Goodman

Bachelors Theses and Reports, 1928 - 1970

In the past the steel industry of the United States has depended almost wholly on imports for its supplies of manganese. Although it is well known that there are enormous deposits of low grade manganese ore in the United States the production of substantial amounts of ferro-grade mater­ial from domestic sources presents a field for con­structive and practical research.

A Study Of The Effect Of Blended Cements On The Durability Of Concrete Incorporating An Inferior Coarse Aggregate, S. T. Collier

Kentucky Transportation Center Research Report

Research Project C-13 was set up for the purpose of studying the effect of blended cement, with air-entraining properties, on the durability of concrete incorporating an inferior grade of limestone as the coarse aggregate. This investigation is not correlated with any Department of Highways field project, being entirely a laboratory study. The tests were begun April 12, 1945, and were completed February 6, 1946.

Durability Of Concrete As Affected By Absorbed Moisture In Tennessee River Gravel Aggregate, S. T. Collier

Kentucky Transportation Center Research Report

This project is more or less a preliminary investigation of Tennessee River gravel relative to the effect of the moisture condition of the aggregates upon the durability of concrete. Certain observations made in the field indicated that absorbed moisture in the aggregate could have a marked effect on concrete, so this study was made in an attempt to give quantitative significance to the observation.

Proposed Field And Laboratory Study Of Flexible Pavements, Kentucky Highway Materials Research Laboratory

Kentucky Transportation Center Research Report

Research into the problem of the design and control of flexible pavement construction has resulted in the use of empirical and arbitrary solutions consisting of general theories for determining pavement thickness, gradation of aggregate, percent of bitumen, base requirements, etc. A desirable method would be one that is applicable to all aggregate, bitumen, and subgrade conditions. Until such a procedure is available, a determination of existing procedures are the immediate problems of highway engineers.

A Proposed Study Of Soils As Related To The Pumping Of Rigid Pavements, Kentucky Highway Materials Research Laboratory

Kentucky Transportation Center Research Report

Pumping has been described as, "The process of ejecting the water-suspended subgrade soil from joints, cracks, and the edges of pavement caused by the deflection of the pavement slab under the action of traffic"(4)*. Obviously, the action is limited to rigid or semi-rigid pavements. Hence, the problem is largely concerned with soil and is almost entirely dependent upon properties of the subgrade. During the past five or six years pumping has become the most discussed if not the most important element of highway soils engineering largely because of the increase in heavily loaded vehicles resulting from wartime traffic requirements.

A Survey And Pedological Classification Of Kentucky Soils, Kentucky Highway Materials Research Laboratory

Kentucky Transportation Center Research Report

At the meeting of the Highway Research Board in Oklahoma City this year the Department of Soils Investigations devoted the major part of one session to a discussion of the pedological method of classifying soils. This was marked departure from past policies for heretofore pedology in soil classification was largely a matter for research, and incidentally, a controversial matter.

Study Of Proposed Specifications For Bituminous Coated Corrugated Metal Pipe, Robert F. Baker

Kentucky Transportation Center Research Report

On February 27 and 28, the author visited the Research Laboratories of the American Rolling Mills Company at Middletown, Ohio. The purpose of the visit was to investigate the technique and background of the new specifications for bituminous coated corrugated metal pipe as proposed by Armco with a view to changing the Kentucky Specifications (throughout this report "proposed specifications" will refer to the specifications recommended by the American Rolling Mills Company).

It is a rather evident fact, but the author wishes to point out that the short visit could furnish only an indication rather than a positive solution to the …

Outline Of Proposed Study Of Sands Used As Concrete Fine Aggregates, Kentucky Highway Materials Research Laboratory

Kentucky Transportation Center Research Report

This investigation is being made for the purpose of evaluating fine aggregates for concrete in which the percentages of fines, finer than the No. 50 and the No. sieves, are increased over that in the normal commercial sands meeting the present specifications for Class "A" concrete. It is a continuation of the studies made in Research Projects C-14 and C-15 (Reports submitted January, 1946), but enlarged to include physical tests on sand, and tests on mortar specimens, as well as the usual tests on concrete specimens.

An Evaluation Of Density And Stability Tests On Bituminous Mixes, Cary Burns, L. E. Gregg

Kentucky Transportation Center Research Report

During the past three years the Highway Materials Research Laboratory has experimented with bituminous aggregate mixes in an attempt to determine the densities that can be obtained through certain methods of compaction and the stability of the resulting mixes. The several investigations have resulted in the preparation and testing of approximately six hundred individual samples, most of which were designed to provide information as a guide for specification on particular field projects.

Proposed Working Plan For A Study Of The Properties Of Coarse Aggregates, Kentucky Highway Materials Research Laboratory

Kentucky Transportation Center Research Report

Among the numerous materials used in the construction of highways probably none is more important or perplexing than coarse aggregate. Through past research and experience a group of procedures and specifications for selecting aggregates suitable for pavements has been developed. These acceptance tests deal almost entirely with physical properties such as gradation, soundness, absorption, abrasion, etc. However, recent data accumulated by field observations and surveys (1), (7), (8)* have indicated that some materials passing the specifications have undesirable properties which cause difficulties over a long period of time. Consequently, research directed toward a more thorough investigation of aggregates has become …

Action Of Diatoms On Clay, Joseph Harvey Renfrew

Masters Theses

"With the recent trend toward the use of higher temperatures and more severe service conditions in the metallurgical and refractories industries there has developed a constantly greater demand for high-alumina clays, that is, clays in which the alumina content is considerably above that of pure kaolinite, Alâ‚‚O₃2SiO₂·Hâ‚‚O. However, the known reserves of good diaspors are so small that ceramic engineers are already turning to basic refractories in order to have sufficient materials for work at high temperatures. Even the slightest reflection on the needs of the refractories industry will show that such substitutions are strictly limited, and possible only where …
