Abstract: Concrete looks often as non-friendly from an environmental point of view. Further developments and new techniques should continue to be introduced into the cement and concrete industry. This will provide distinct alternatives to an OPC dominated cement market.One of such strategies is based on advanced concrete technology concepts, which enables the reduction of the quantity of cement used in concrete, by combining supplementary cementitious materials, fillers, and various admixture technologies. The production of the so-
called “low water demand binder” (LWDB) is considered to be an example of such approach.The LWDB technology makes it possible to produce binders with a wide range of material composition and properties varying from multicomponent low-clinker binders with 15...25% of clinker consume to pure clinker binders, the mineral part of which is presented only by clinker component and gypsum. Clinker consumption per 1 m3 of concrete and per 1 MPa of concrete strength, as well as specific energy inputs seems to be brought down to an extraordinary low level that allows considering LWDB as next-generation cement.Development of the codes, standards, guidelines, and training and certification programs will play a significant role in the elaboration and acceptance of the alternate concrete design.
