Hello friends,
I am Arjun Sakhiya study in Civil Engineering in Gujarat Technological University I want to make CEMENT from waste materials like plastic waste, etc. please help me as soon as possible.
I used a cement with high percentages of granulated cinder (CEM III/a) and additional I replaced the cement clinker by fly ash (1/3).
Granulated cinder and fly ash are both waste materials.
Hi, Arjun-
If you want to use them as a cementitious material, the first thing that you need to do is to get their chemical composition to see if they can be utilized for such a purpose.
If your main point of interest is the sustainability advantages of usage of waste plastics, then you may want to try adding them in concrete mixtures as aggregate replacments instead of the cement itself.
Good luck with your research
I suggest that before trying to make cement from plastic waste, you try to read about the chemistry of cementitious materials. Taylor's "Chemistry of Cement" is a good point to start with. Research about alternative cementitious materials is not a new topic and many materials were studies in this regard. Read for example the paper of Gartner and Macphee reviewing the most of the alternative binder systems:

Hi Arjun
Do you want to incorporate the waste products as filler in the concrete, or are you looking at waste products which could be utilized as cement extenders? Much research is available on both topics, eg google scholar
Or do you want to cut out cement totally and perhaps look at plastic polymers (using lego-type construction)?
Greetings.
I recommend using materials sub-products of industrial processes rich in silice or some pozzolana of oigen ceramic even metacaolin
Semion Zhutovsky response is on point Arjun. Know the basics and key requirements first...
Hi Arjun,
you can try to replace aggregates with recycled concrete aggregates, check this out:

There is a great scope and potential Mr. Arjun, considering the Indian scenario is concerned. But it is equally challenging too.
Compressive Strength is being regarded as the single point criteria for any new type of developed concrete. But with the addition of waste you will loose concretes compressive strength. Be more judicious in effectively using any kind of waste in the production of concrete.
Hello
Industrial byproducts that are waste materials have a lot of potential, like mr. Bolognini said. My research is related to red mud, byproduct of alumina production. You can even try with different combinations.
Good luck
Since the predominant ingredients present in the cement are silica and alumina,Choose the pozzolonic materials such as GGBS ,fly ash,rice husk ash etc...which should be rich in the alumina and silica,as silica gives strength to the cement and alumina decide the setting time of the cement.
Hello dear you may prepare the cement by utilising Rice husk ash due to high content of amorphous silica which is more reactive than crystalline silica
