7. Large Cement Globe from a Rubber Ball. These cement garden balls were made by coating children's rubber balls! First a layer of saran wrap was used to cover the rubber, then fabric soaked in cement was smoothed over the surface and allowed to dry. Once dried, a mixture of 2 parts sand and one part concrete was spread all over the ball.

When mixing merely sand, cement, and water, you get a material closer to mortar. You can purchase concrete with a high sand content or even a no-fines concrete where they exclude entirely sand in favor of coarse aggregates. This article will take a close look at the different methods of mixing concrete, what they contain, and their applications.
