Reactive Concrete

There are many different types of concrete in the world. Each of the them are having added advantages and disadvantages when compared to each other.

For example, if concrete is made from the sulphate-resisting cement then it is good in resisting concrete from sulphate attacks but will not be good in strength as compared normal or traditional concrete.

Different concretes are been developed in the world for different purposes. Some of them are used under water some of them for rapid hardening, some of them in Ready mix concrete etc… one of them is this reactive concrete. This was first developed by P.Richard and in the early 1990’s. this RPC is prepared by replacing the ordinary concrete with quartz powder, silica fume. It has very high strength and also ductility. The compressive strength may vary from 250-810 Mpa.

Reactive concrete will have very fine powders such as sand, quartz, steel fibres, super plasticizer and cement. The quantities used are generally as follows: OPC – 1000, Water -18, Fine sand – 500, Silica Fume – 230, Quartz powder -390, Super plasticizer – 18, Steel fibers – 630 all the weights are in kg per cubic metre. And this mix give approximate strength of 800Mpa.

Requirements:

Knowledge of concrete technology.

Knowledge of Mix Design.

Cement

Sand

Quartz Powder

Silica Fume

Steel Fibers

Super Plasticizers

Test apparatus for the concrete (concrete lab can be used)

Project Implementation:

1. Make the mix design of required grade (Refer IS 10262)
2. Find the quantities and make the cubes.
3. Test them for the compression, tensile and flexural strength.
4. Make the reactive concrete from the materials above and in different proportions.
5. Make the cubes and test it for all parameters.
6. Report the difference between both the concretes.

Software Requirements:

• If you need to plot the graph for the values you can use software like MS-Excel, Origin Pro etc…

Advantages:

• It makes concrete void proof as we are using fine ingredients.
• Greater resistance for the earth quake loads
• Reduction of the dead load
• Higher shear capacity.
• Higher Ductility

Disadvantages:

• Expensive as we are replacing the aggregates.
• No official code for the design concrete mix.

Conclusion:

This project is still in development stage and do more improvisation by adding or removing the materials used in it. If you want to make something new or learn something new regarding the concrete technology then you can do this project and experience it yourself.
