Concrete aggregate alternatives - Appropedia: The ...

2021-5-10  High-density polyethylene can be added to concrete and sand as a feasible replacement for course aggregate. Research has shown that plastic bags that are tightly packed and then heated, shrink to a size that can easily be used in concrete. But as the name implies, the material is too ductile at full strength to support structural loads at 2500psi.

Study of Partial Replacement of Natural Aggregate by ...

2017-11-20  Concrete is a composite material, basically consisting of different constituents such as binding materials, water, aggregate and admixtures. Among these ingredients, aggregate plays a very crucial role in concrete which occupy the largest volume of about 60–75% of total concrete volume. The versatility of concrete as construction material for large construction work lies in its high strength, low maintenance cost, resistant to weathering effect, economical and excellent structural performance over other construction materials. Moreover, the extensive increase in the rate of industrialization and urbanization due to the parallel growth in economy and population has made the use of concrete as the most non-sustainable material as it is consuming the maximum amount of natural resources. Concrete has a very important role in the economy development of a country due to its large volume utilization. It uses approximately 20 billion tons of raw materials (coarse aggregate) each year. With this increase in rate of consumption, it is expected that the demand of aggregate
