Effect on compressive strength of concrete with the addition of solid waste

Published on 19 Apr 2022. Written by Reddy Shekar

The disposal of waste materials is always been a major problem for environmental engineers. Solid waste has the most adverse effect on the environment compared to liquid waste.

Because liquid waste can be used for domestic purposes with the help of the treatment process. In recent times, the engineers and researchers find the solution to reduce the effects of solid waste on the environment. The solution is using the solid waste incineration ash as one of the ingredients of concrete. The addition of solid waste improves the properties of concrete to ensure the maximum efficiency in the construction.

Composite concrete is a new and advanced concept which became more popular in the construction industry in recent times. High strength, easy to work and low cost are the few reasons for the popularity of composite concrete. There are many types of admixtures or materials available such as fly-ash, rice husk, natural wood resins, silica fume. Among all these admixtures or materials solid waste is the easily available material at no cost.

The generation of solid waste has been increasing at a much faster rate due to the increase in population, a number of industries, urbanization, etc…. The disposal process of solid waste is difficult and expensive. Using solid waste incineration ash as the admixture is the best way to overcome these problems. The solid waste replaces the maximum cement content in concrete thereby environmental effects due to cement can also be reduced.

Materials Used:

1. Cement – Ordinary Portland Cement
2. Fine aggregate
3. Coarse aggregate
4. Water
5. Mineral admixture – Municipal solid waste incineration waste.

Project Implementation:

1. Collect the solid waste incineration ash from your nearest waste incineration plant.
2. Conduct the physical test to find the initial properties of solid waste incineration ash.
3. Prepare the mix design of concrete.
4. Add the incineration as 0, 10%, 20%, 30% and 40% in cement.
5. Prepare the concrete cubes with different percentages of solid waste incineration ash.
6. Perform the compressive test on concrete cubes using Universal Testing Machine (UTM).
7. Find the ideal percentage of ash used to prepare the concrete cube. Which has the highest compressive strength.

Applications:

1. Eliminates the disposal problems.
2. Reduces the environmental pollution by replacing the maximum content of cement in concrete.
3. Economical.
4. Increases the compressive strength of concrete.
5. Improves the workability of concrete.

Conclusion:

Solid waste incineration ash using as an admixture is the best method to improve the compressive strength of concrete in an economical way.
