Functional bionanocomposites based on two layered silicates, the commercial montmorillonite known as Cloisite®Na and a natural bentonite from Algeria, were prepared by intercalation of cationic starch, synthesized with two different degrees of substitution, 0.85 and 0.55. After characterization of the prepared bionanocomposites by XRD and zeta potential measurements, batch studies were conducte...

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 study was to evaluate the efficacy of a yeast glucomannan (YG) and sodium bentonite (SB) in reducing the toxicity of aflatoxin for broilers fed a diet naturally contaminated with aflatoxin. In total, 300 7-day-old Ross 308 broilers were randomly assigned to 10 dietary treatments, consisting of a diet with no aflatoxin (positive control), a diet naturally contaminated with 250 pp...
