As the mix prepared contains e-waste and coarse aggregate, the corresponding weights per meter cubic of concrete for different proportions are represented in table 2.Proportions of materials for different combinations the coarse aggregate used in this study is the combination of e-waste and the coarse aggregate.
Replace fine aggregates or natural sand as if you replace fine aggregates from concrete it will become no fines concrete used for specific purposes to prepare pervious media.If you want to replace natural sand on the other hand there are ple.
The manufacture of coarse aggregate by crushing rock ballast causes environmental pollution.Now a day there is a scarcity of coarse aggregate due to increase in cost and infrastructural growth.This mainly directed towards exploring the possibilities of making effective use of alternative materials.The rubber aggregates.
Concrete is a mixture of cement, fine aggregate and coarse aggregate, which is mainly derived from natural resources.Increasing population, expanding urbanization, climbing way of life due to technological innovations has demanded a huge amount of natural resources in the construction industry, which has resulted in scarcity of resources.
In this article we explore the importance of aggregate testing, various tests on aggregates and all the important properties of aggregates.Aggregate is one of the primary building materials and constituent of concrete.Aggregates are used in construction and include sand, gravel, crushed stone, slag, recycled concrete etc.
Coarse aggregate used in concrete productions are gravel, crushed stone, granite, and limestone.Therefore, there is a need to explore alternative building materials from industrial waste materials that can be recycled.Ceramic tiles are often discarded as.

Brick aggregate concrete also performs well or even better than natural aggregate concrete under high temperature fouad et al.All these studies justified the use of crushed brick as an alternative source of coarse aggregate in concrete.However, there is hardly any literature on use of brick aggregate in pervious concrete.
This paper deals with the possibility of using fresh concrete waste as recycled aggregates in concrete.An experimental program based on two variables proportion of fine aggregates replacement and proportion of coarse aggregates replacement was implemented.The proportions of replacement were 0, 50, and 100 by mass of aggregates.
Use of waste in concrete research efforts has been done to match societys need for safe and economic disposal of wastematerials.The use of waste materials saves natural resources and dumping spaces, and helps to maintain aclean environment.The current concrete construction practice is thought unsustainable because, not only it isconsuming.
An alternative sustainable coarse aggregate for natural coarse aggregate can reduce the amount of pollution and preserve natural resource.An attempt is made in this research project to use locally available soil from e site and flyash waste to prepare an alternative sustainable coarse th aggregate for concrete to be used in small constructions.
