STUDIES ON MECHANICAL, THERMAL AND PERMEATION PROPERTIES OF HDPE (BLOW GRADE) WITH MICROSILICA CLAY
Abstract: HDPE is widely used in container applications. The mechanical properties and barrier properties can be further improved by the addition of reinforcements like nanoclays. But, however the cost of nanoclays are higher about Rs.5000 – 6000/kg whereas micro silica cost is economical about Rs.450-1000/kg. Hence we used micro silica of 270nm particle size in this project with HDPE blow grade. HDPE (High density polyethylene) was melt blended with micro silica …

Review of Nitrite Inhibitor for Protection of Rebar Corrosion
Abstract: Load bearing concrete structures need steel reinforcement (rebar) strips or rods, which are prone to attack by the corrosive environment inside the concrete due to constant ingress of moisture, pollutant gases and anions (mainly Cl-, SO4- -). One of the means of reducing such type of corrosion is the use of inhibitors. Inhibitors are water soluble but film forming on metals by their selective adsorption on the metal surface. These …
