The present investigation deals with effect of bentonite clay on concrete. The concrete was produced by partial replacement of OPC with mineral admixture bentonite clay in percentages of 0%, 5%, 10%, 15% and 20%. The M20 grade of concrete was designed. The compressive strength, split tensile strength and flexural strength were found for the specimens. The present investigation is to study the e...

the aim of this research was optimization of refining of raw sugarcane juice using bentonite for production of natural liquid sugar or cane honey. non-sugar substances of raw sugarcan juice contains: colorants, polysaccharides, gums, proteins, etc that affect on efficiency and quality of the final product and should remove from raw sugarcane juice. gelatin is a protein which is used as an aid c...

Three-layered clay minerals such as montmorillonite (bentonite) exhibit very short transverse relaxation times. This is especially true for samples with relatively low water contents in the region of 20% to 30%, which is the water content typically used in environmental technology applications (e.g., as a mineral liner material for landfills). The diffusion of water in samples with such short t...

A comparison is made of tests for thyroglobulin antibody, using gel diffusion, electroprecipitin, bentonite flocculation, tanned red cell agglutination, and latex slide agglutination techniques on sera from cases of Hashimoto's disease and other thyroid disorders. Any increase in gamma globulin was also noted from the serum electrophoretic pattern. The gel diffusion and electroprecipitin tests ...

In this study, the main objective is the preparation and the characterization of a modified Algerian bentonite based adsorbent by intercalation with hexadecyltrimethylammonium bromide (HDTMA). Natural and modified bentonites were characterized using thermogravimetric analysis (TGA), X-ray diffraction (XRD) and infrared spectroscopy (FTIR). The X-ray results indicate that the geometry of the int...

Sodium bentonite was subjected to the effect of two new homologue series of chlorides (alcoxymethyl) dimethyloctyloamonium chlorides and 3-alcoxymethyl-1-octylimidazole chlorides with the hydrophobic substituents of the same length. Morphology of the obtained modified bentonite was studied under scanning electron microscope [SEM] and the degree of adsorption of the ammonium salts was determined...
