Blend up of Concrete paver with Polypropylene fibre at controlled percentage
Authors: Aman Gupta
Abstract
Concrete block pavement was put forward in The Netherlands in the beginning of 1950s as a substitution for baked clay brick roads. The normal worldwide movement in the direction of enhancement of city pavements , the increasing price of pitch as a paving substance and the quick rise in building and maintenance price have motivated designers to rotate paving substance viz. concrete blocks.
Chemical Characterization and Physico Chemical Properties of Cashew nut (AnacardiumOccidentale) Oil and Cashew nut Shell Liquid
Authors: R. Govindaraju
Abstract
Proximate composition and mineral concentration of Cashew nut (Anarcadiumoccidentale) were investigated using standard analytical methods. The physicochemical characteristics of cashew nut shell liquid were also determined. The proximate composition (%) was as follows: moisture (7.2), ash (2.8), crude fat (49.1), crude protein (36.3), crude fibre (3.2) and carbohydrate (by difference) (1.4). The mineral composition (mg/100g) of cashew nut showed potassium (27.5 ± 0.4) to be the highest, calcium (21.5 ± 0.0), magnesium (19.3 ±0.1), sodium (8.2 ± 0.2) and phosphorous (14.0 ± 0.2). Zinc and iron concentrations were lower.
Utilization of Plastic Wastes in Road Construction
Authors: Satyabhan Singh, Prof.B.P Mudgal, Ms.Anuradha Sharma
Abstract
Plastic is a toxic & persistent material available in world. It is generally found to be nearly 5%-10% in Corporation Solid Wastes (CSW) which is a major environmental threat. Present day, industrial plastics are used in our day-to-day life for Various purposes via carry bags in various shops. Plastic made manufacture materials are used for making roofs of temporary kutcha houses and hutments, packaging materials in LDPE & HDPE. Which manufacturing industries, in use of drinking water supply, sanitary appurtenances and in electrical appliance. Industrial plastics based materials product and appliances used for domestic used .The results of Life Cycle Assessment (LCA) of these plastic materials is not satisfactory.
