Based on the studies conducted on strength characteristics of concrete made with utilizing waste materials, it was found that the concrete made of waste ceramic tile aggregate produced similar strength in compression, split tensile and flexure as conventional concrete. The compressive strength of concrete cubes made with ceramic
materials which can remain for next generations. Secondly, the principal binder in concrete is Portland cement, the production of which is a major contributor to greenhouse gas emissions that are implicated in global warming and climate change. Thirdly, many concrete structures suffer from lack of durability which may waste the natural resources.

How to transform plastic waste into paving tiles 2 made with this technique make good insulation, keeping you warm in winter and cool in summer. The sand in the tiles acts as a fire retardant. If there is a fire, the outer layer of plastic melts, leaving a face of sand. Sand is not flammable, so it slows the spread of the fire through the brick.
Jun 30, 2011 · The concrete industry is marketing the concept of concrete’s sustainability by highlighting its long service life and eventual reuse possibilities. CCA can make concrete a continuously recycled product. Unlike some recycled materials, the properties of concrete made with CCA and SCMs can be superior to those made with virgin material alone.
Concrete is recycled by using industrial crushing equipment with jaws and large impactors. After the concrete is broken up, it is usually run through a secondary impactor and is then screened to remove dirt and particles and to separate the large and small aggregate.
