What's wrong with cement which is a highly used material in the construction industry.  cement has good binding properties than other binding materials like if we compare with lime. so let's go to know two major regions which insist us to find out other alternatives. CO 2    Emission :  About 1.35 billion tons made per year Ordinary Portland cement (OPC) is typically used in the production of concrete as a binder.  In the production of OPC carbon dioxide (CO2) is also produced.   OPC is responsible for approximately 7% of the total CO2 emissions released into the atmosphere per year worldwide. so d ue to many environmental concerns, the need to develop a new, sustainable alternative for OPC is needed. Workability :  Another problem faced by OPC concrete is related to its durability issues. OPC has a relatively high permeability, thus allowing water and other harmful media to penetrate concrete, causing corrosion and carbonation proble...
