I don't think so, concrete is made in a chemical reaction, making the change irreversible. it is possible to mix the broken down concrete with new concrete, but you cannot simply remix and remould it.
I hope this answer benefits you.
Actually it changes ratio of cement to the other contents of concrete (Sand and crush). However an optimum percentage of cement sand and crush is decided by trial casting of concrete
You can't
limestone is used to make cement
As of right now there are no plans to remake it,although there is alot of talk about it
A small cement silo works by storing dry cement powder and releasing it into a mixer or conveyor system through a controlled discharge mechanism. The silo typically has an aeration system to prevent clogging and ensure a consistent flow of cement. The cement is loaded from the top and can be unloaded from the bottom through a screw conveyor or air slides.
Limestone is refined to make portland cement.
clay + limestone = cement
Its 2012...
As of May 2015, there is no evidence a remake of Ghost is being considered.
Yes. The cement used to make concrete usually has sand, aggregate and Portland cement in it. That would make it heterogeneous.
cement is made with water cement mixture and sand after all of this is added
it is mixed with clay to form cement.
