Recycled Materials in Concrete for Foundations

What is the best recyclable material that can be mixed in concrete for foundations in Kamloops, B.C.? This report will focus on three types of recyclable materials consisting of used tires, plastic and glass. All three materials will be crushed or shredded and then mixed in cement to produce a green concrete that is superior to the normal concrete used in foundation walls.
Used tires can be shredded and then mixed with cement to produce a rubberized concrete. Using these tires in concrete has many pros that include rubber having a long life expectancy and being water resistant. Rubber is cheap and gives the surface of concrete some give in both tension or compression. You only need about half the amount of rubber to achieve the same amount of strength. The cons of using rubber in concrete include it being difficult to apply, and that it poses a hazard to workers working with it. Rubber also reduces compressive strength and gives a loss of stiffness to the concrete.
Plastic can be shredded and then mixed with cement to produce a plastic concrete. Using recycled plastic in concrete seems to have many pros and very few cons. Some of the pros include plastic being extremely versatile, durable, light in weight and resistant to chemicals, water and impact. Plastic has excellent thermal and electrical insulation properties, has a low production cost, and is non degradable. However the most important property of plastic is its high strength and ability to improve compressive strength in concrete. The cons of using plastic in concrete are that plastic contains potential harmful chemicals and that it decreases in strength in higher temperatures.
Glass can be crushed as aggregate and mixed with cement to produce a glossy looking type of concrete. Using the recycled glass proves to be a good idea for foundations because it increases the compressive strength in concrete. Other pros consist of the cement increasing in strength in higher temperatures, and its ability to resist abrasion. Glass is very durable and also has the ability to resist water. In addition, the use of fine glass is proven to give better results in concrete than course glass. The only con of using recycled glass in Kamloops, is that there is no local glass recycling plant nearby.
In conclusion, using either plastic or glass in concrete seems to be the best choice. In both materials the pros out way the cons by a mile. Further test at the local concrete plant will help determine if the predictions are correct.

Conclusions

Between my three choices of materials in concrete ( tires, glass and plastic ), my conclusion is that glass or plastic would be the best choice. Both glass and plastic increase the compressive strength in concrete, which is vital in building foundation walls.

To further test these methods I plan to go to the local cement plan and test my theories on compressive strengths. I will also test other benefits such as life expectancy, resistance to water and sound and how these materials react to kamloops temperatures.

Pros and Cons of Plastic in Concrete

Pros

- Extreme versatility and ability to be tailored to meet specific technical needs.
- Lighter weight than competing materials reducing fuel consumption during transportation.
- Durability and longevity.
- Resistance to chemicals, water and impact.
- Excellent thermal and electrical insulation properties.
- Comparatively lesser production cost.
- Unique ability to combine with other materials like adhesives.
- Low density and high strength
- Non degradable
- Improves Compressive strength
- Increases in strength with time


Cons

- Potential harmful chemicals
- Decreases in strength with higher temperatures

Updated Theosis Question

Updated Theosis Question- What is the best recycleable material that can be mixed in concrete for foundations in Kamloops, B.C..

I will be compairing recycled tires, plastic and glass and their compressive strengths once mixed in concrete

Glass aggregate in Concrete

Doing a little more research it looks like recycled glass in concrete increases the compressive strength of the cement.

Pros
-Fine glass is better than course glass
-Cement gets stronger in higher temperatures
-Cement looks glossier
-Resistance to abrasion
-Durable

Cons
- No recycled glass plant in Kamloops

Pros and Cons of Recycled tires in Concrete

Pros
-Rubberized Concrete has a long life expectancy
-Cheaper
-Only need about half the amount to achieve the same strength
-Surface gives a little
-Less concrete is used


Cons
-Difficult to apply
-May pose a hazard to workers working with it
-Reduces compressive strength therefore not good for foundations
-Loss of stiffness

Recycling Tires in Concrete

Recycled tires can be used in concrete. There seems to be many benefits according to energyjustice.net and very few cons. It seems good for roads but im looking to do some more research and see if i can apply it to concrete in foundations

Contribution of the Project to Academic Goals and Objectives

My role in conceiving the project is to take an unbiased route. The main form of the research project will consist of my own reports and calculations in the concrete field. Other areas will consist of unbiased results from books and online resources.
In order to implement the project I will begin to research throughout the summer of 2010. The first place I plan to start is the local cement plant (Kemp Concrete). There I will hope to conduct samples and test materials for my study. Once my results are compiled I will research concrete from reliable resources using books and the internet. Once compiled I will put together a report to compare types of concretes and reusable materials and the prices.
My academic objective is to complete the applied research project by Feb.1 of 2011 and to finish the ARET diploma. This project will allow me to prove I can complete an applied research project in a timely manner and prove to fellow instructors that I am ready to begin my career.

Research Proposal

Research Topic Proposal

Research Topic Title: Can you use Re-usable Materials in Concrete to Build Foundation Walls in, Kamloops, British Columbia and How Much Will it Cost?

Summary Statement: The goal of this proposal is to advance in the use of green re-usable materials. Possible research may include a further look at fly ash and aggregate in concrete, or any other materials used to reduce the amount of concrete used each year. The proposal will also include an examination of the strengths of reusable concrete and there costs.

Purpose: Researching re-usable materials in concrete will help provide people with knowledge of how re-using materials can help the economy and save money. It is a step towards making people realize, green is the future.

Goals: Possible outcomes from this research include, samples of concrete showing the difference in the strengths of normal and re-usable concrete. Examples and equations will be given to prove the results of the applied research. Other outcomes may include calculations from the British Columbia Building Code 2006, and a cost analysis break down of how much the re-usable materials, will save you in cost.

Methodology and Analytical Approach:
Content- Will be based on books, the internet and most importantly, the results of experimenting with the concrete. The results will test the concrete strength and the materials used to make it.
Materials- Will consist of samples with different recyclable materials in the concrete.
Presentation- Methods of computer graphing, white paper, and samples will be used to display a presentation. This presentation will allow viewers to get a close look at what the re-usable materials in concrete look like, and to show how the concrete was made. In addition, graphs and white paper will give a breakdown of the research done and show how the calculations were derived.

Related Information: The knowledge of re-usable materials in concrete would allow communities to build green. When most people think of building green they think about the extra money and amount of time that will be needed. This research topic will prove to people building green saves you money and time. It will fill the knowledge gap and give people the information they need to know in order to persuade them. With the help of the internet and books, and some innovative research done at the local cement plant, research will be done to prove how it is possible to be green with re-usable materials in foundation walls.

Plans for Dissemination of Work: In order to allow the community to participate and gain knowledge on the subject, a blog will be placed on our local university web page at www.tru.ca. In addition the final project will be displayed at local and recommended seminars.
