Investigation of corrosion in steel General purpose cement. Why we investigating it, Induce a certain crack and observe what may happen?

Fly Ash

It is a by-product of coal combustion in power stations. It also provide environmental advantages. Overall performance and quality of concrete. It affects the plastic properties of concrete by improving workability, reducing water demand, controlling bleeding, and lowering heat of hydration. Fly ash increases strength development at later ages, reduces corrosion of reinforcing steel, and generally improves resistance to chemical attack and mobility through a reduction in permeability.

Grade 1 Fly Ash

It is a supplementary cementitiious material that delivers improved later-age strength, workability and enhances the durability properties of concrete. Commonly used as 20%-30% cement replacement in concrete. Grade 1 Fly ash is used as a single product or may be blended to produce a Fly Ash blended cement. Grade 1 Fly Ash is recommended for use in virtually in conventional concrete applications

Special Grad Ash

Its an Ultra fine high performance fly ash product that both increases the density and reduces the permeability of concrete by providing a filler effect and a reactive cementitious material. It is particularly effective for providing water tightness in higher strength and high durability applications.

Minutes with AdilAbbas( Major Stake holder) (3/05/16)

I am having regular meeting with Adil Abbas who is the major stake holder of this project. We have discussed few key points during the meeting and they are:

-Look for risk plan

-Look for standards- Australian standards quality and prepare client brief

-Quality management plan

Consistency of result-Document work procedure
Report parameters
Work performed
Documents and presentation

-All aspects of the project is free from mistakes

-Australian standard-recovery procedure

-Why Corrosion is a problem?

-Documenting the notes and put it into report as appendix. it has to be part of quality plan organising meeting with Adil, documents it with quality plan

-Risk assessment-making sure I keep an electronic copy. what if i loose the hardcopy? I need to have a backup

-Specification of blended cement-Australian standard

-Australian standard of general purpose cement

-Australian standard of blended cement

Minutes with AdilAbbas( Major Stake holder) (10/05/16)

Concentrated salt solution.

Normal concrete.

add fly ash to cement

after 7 days keep them for 14 days, put them into salt solution and check how much is it corroded?

Research on slag

Work on risk register

Work on quality management plan

Work on Australian standard- method of testing corrosion

Minutes with AdilAbbas( Major Stake holder) (17/05/16)

Find out how much cement, water, how much concrete.

Slum, water cement ratio

Go to companies and find out.

Experiment1 beam with normal cement

Another 1 partly replace slag and lime

Prepare concrete cylinder..

look for method for testing compressive strength for concrete.

Blended cement composition. Australian standard will tell composition of slag material which you add that will help determining the mix proportion

Decide how much material do I need?

Prepare at least 3 compositions

Plane
Limestone and slag
cement and slag.

What slum you want. It is important to determine the water cement ratio?

What mix proportion do I need

Minutes with AdilAbbas( Major Stake holder) (01/06/16)

I had a brief discussion regarding the experiment that I have to carry out. Adil Abbas has asked me to go to library and suggested me to look for the Australian standard website in order to find the standards. I was asked by Adil to work on water cement ratio, compression test.

With the water cement ratio he has given me 3 types. 1st one is water cement ratio of 0.40. 2nd one is water cement ratio of 0.50 and the 3rd one is 0.60.

I was told by Adil that the water cement ratio for casting slump would be 80 to 100mm, if in any case I can't get it then I have to use chemical plasticizer.

2000 words + diagrams and calculations.
