Determine your wall's area: Determine the area of your wall. The formula for a square wall is Length * Height. Square Wall Area = Length * Height. Make sure to take into consideration the often-overlooked information that will affect the area of your wall – for example, the depth of your beam or the underground foundation CHB.
Plastics are non-biodegradable and the increasing generation of plastics creates a problem of disposal. One promising approach to address this problem is to find other uses for plastics after they are used. While studies on the incorporation of waste materials in concrete abound, little attention has been given to the incorporation of …
