Green concrete is a broad term. Usually this is how geopolymers are called, where cement binder is substituted by metakaolin (or other material rich in aluminosilicate, like some fly ashes, mine wastes, volcanic rocs). Geopolymers usually are produced by mixing of mentioned above aluminosilicate precursor with sodium or potasium silicate soluble in water.

Hi dear colleagues
I believe that green concrete is an eco-friendly or low environmental impact concrete. Replacing of one or more of concrete constituents with waste or recycled materials can produce green concrete. Geopolymer concrete is a green concrete due to the replacing of cement (and consequently reduce the CO2 emissions that result in the cement industry) with by-product or low environmental impact materials. Replacing of the natural aggregate with recycled materials can also lead to produce green concrete.
Regards.
