    Any idea about concrete mixture used in the 3d printing machine process.

    Seems to me that that the mix depends on what you or others want to print. For example, are you contemplating small-scale concrete printing as in, say, a small decorative sculpture or large-scale concrete printing such as components of a structure or an entire bridge or building, etc.

    3D printing concrete mix will be the revolutionary technology forever.
    It's a technology through which we manufacture the elements by using some binder and some other favorable material.
    Firstly we prepare the 2D model of element and again by use of the 3D printer, we layer out again and again to make a proper shape.

    The advantages are:
    We make elements more economical in addition to better quality controlled. 
    It provides flexibility to structures for a suitable construction 
    We are able to avoid the excessive material which may take place by slight mistake.. etc..

    ​Since it is a pumped concrete, I would think these might be good resources:

    For concrete 3d printing the first thing you need to know is the pumping/extruding process and printing speed. It is not surprising that every printer has a different concrete mix design. It all depends on your robot mechanical design. After that, there must be a balance between workability and flowability. Then, you must run trial tests.

    First thing you need is to design the control of the concrete movement. You do not want to print in every point at a surface, but only in some parts for doors and windows. So, you need to think in a way to stop the concrete movement in that moment.

    We are working in our printer too. I will be glad to share any useful information.

    Thank you all for this interesting subject. 

    Can you direct me to any specific scientific paper about it?

    Is there any ongoing 3D Printing research work that seeks  to eliminate or reduce over-dependence on the use of Portland Cement? Instead, it promotes the use of locally available more environmentally friendly materials...

    A friend of mine, Jason Ballard co-founded ICON, an Austin based construction company that just unveiled the first city-approved/permitted ​home using a Vulcan 3-D printer.

    I followed up on Keith Dosch's reference to ICON's project in which they 3D printed, in concrete, a house in Austin. Thank you Keith.

    If "we" can do that, why aren't the precast industry and the cast-in-place industry 3D printing (in concrete or other materials) structure components or actual structures such as buildings, bridge piers, wastewater treatment plant tanks, floating docks, wall panels, beams, columns, roofs, slabs, and railroad ties?

    Maybe those industries, in the U.S. or elsewhere, are doing R&D work on large-scale 3D printing.
