Replacement of Sand with Shredded Plastic in Cement Concrete. Vikas Khandelwal. Assistant Professor, Chandigarh University, Mohali, Punjab (India) Abstract The concrete is the second largest material using on earth after water. In India, approximately 400 million metric cube concrete is being used every year and is increasing day by day.
ABSTRACT. Concrete is a mixture of fine aggregate (sand), coarse aggregate (rock), cement, and water. The increasing demand of concrete for construction and development of infrastructure has drawn the attention of many researchers in searching for less expensive alternatives to the traditional materials employed in the construction industries in an attempt to reduce the high …
Hence, one can replace the river sand up to 25%-50% in the concrete mixes. This type of replacement has a lot of advantages to the environment as well as human kind. Therefore, replacement of river sand with construction and demolition waste is recommended. Also Read: Recycled Concrete Aggregates: Its Properties & Uses.
Concrete is the most undisputable material being used in infrastructure development throughout the world. It is a globally accepted construction material in all types of Civil Engineering structures. Natural sand is a prime material used for the preparation of concrete and also plays an important role in Mix Design. Now a day‟s river erosion and other environmental issues have led to the ...
The use of natural sand as fine aggregate in concrete is becoming problematic due to scarcity and pressure on mining of the resource. Alternate sources such as the use of industrial waste as replacement of natural sand in concrete are gaining popularity as a …
