**Abstract**

The environmental problems accompanying concrete come from cement. This means that the final product i.e., concrete is an environmentally sociable material by itself. This guides us to play on the concrete constituents which cause the largest environmental impact, which is cement. Therefore, if we can abate cement amount and increase cementing materials which can substitute cement for concrete, we will be able to minimize the concrete impact on the environment. The saving of cement quantity in concrete can be realized by substituting it with diverse extra cementitious materials which are a by-product of another industry and waste of agriculture.
