The compositions of ceramic masses for facing slabs based on Angren secondary kaolin and clay were developed, using metallurgical waste–iron–containing dust from the gas cleaning “Uzmetkombinat” JSC sandy waste Toytepe fluorite enrichment plant. With help differential thermal X–ray phase analysis, chemical–mineralogical compositions, exothermic endothermic effects used components determined dur...

BACKGROUND The potato psyllid, Bactericera cockerelli, is a vector of Candidatus Liberibacter solanacearum, causing several diseases in solanaceous crops. Laboratory and field no-choice and choice experiments were conducted to evaluate the repellency of kaolin particle film on adults of B. cockerelli on tomato plants that had been sprayed with kaolin particle film on the upper surface only, on ...

of specific interactions between metal oxide surface hydroxyl groups or adsorbed water and the oxygen of Eleven well characterized humic substances (HSs) were adsorbed adsorbed carboxyl or hydroxyl groups of organic acids from aqueous solution onto a Na-kaolin clay. The adsorption affinity (KL ), maximum adsorption capacity (b ), a coefficient of desorption including HA (Parfitt, 1977; Yost et ...

Abstract A high-cycle accumulation (HCA) model predicting the of permanent strain or excess pore water pressure in clay under a large number load cycles is presented. Data from an extensive laboratory testing program on kaolin undrained cyclic loading has been analysed for that purpose. The influence amplitude, void ratio, stress overconsolidation ratio and frequency rates considered constituti...

Earth-dam failure starts with cracking in the clay core, and this is not easy to detect prevent. Therefore, swellable a feasible solution, which helps close cracks automatically based on self-healing process. The presented study utilizes experimental procedures analyze swelling behavior of fine-grained clayey soils prevent structural regarding crack generations. In regard, materials were modifi...

A variety of clay specimens (Kaolin, Belfast Upper Boulder Clay and Belfast Sleech) were subjected to British Standards Triaxial Permeability Tests and Accelerated Permeability Tests in order to examine how the permeability predicted (under uniform effective stresses and conditions) varied depending on the testing method adopted. The specimens were then freeze-dried to preserve their post-test ...

Fiberboard is a common interior material used both in China and the United States of America. The increase in demand for interior materials has raised concerns regarding combustibility of the materials. The pyrolysis characteristics of fiber, phenolic resin (PF), and nano kaolinclay (NK) were investigated using thermogravimetry. The fire performances of samples coated with a mixture of NK and P...

Refractory clay tiles are composed of kaolin, which is the commercial name of clay, and this consists mainly of kaolinite mineral. Two such tiles and caowool packed in glass columns were used for the immobilization of Acidithiobacillus ferrooxidans cells in a ferrous iron medium, which was percolated through the supports. Colonization was carried out by several media replacements with no furthe...

It has long been recognized that the minerals in the clay (<2 gm) fractions of soils play a crucial role in determining their major physical and chemical properties, and inevitably, questions concerning the origin and formation of these minerals have assumed some prominence in soil science research. This review considers some important aspects of these questions and is confined to clay minerals...

The purpose of the present study was to assess the effect of kaolin feeding on health status, body weight gain (BWG), course of diarrhoeal infections caused by enterotoxigenic strains of Escherichia coli (ETEC) and the level of mycobacterial contamination in weaned piglets. The testing was performed in two experiments involving 40 weaned piglets at the age of 28 days. In the infection-free expe...
