This paper introduces the recent state of research on creep of new concrete made by replacing the cement with a utilizing recycled active additive coming from waste glass and adding a montmorillonite mineral nano particles and comparing it to a control concrete. Several kind of concrete mixes using unconventional additives have been developed and prepared. Specimens were tested in two extreme environments: in one case there was 100% humidity provided by protecting the specimens from desiccation and in the other case specimens were air-dried and protected from any moisture. Concrete specimens were loaded in a constant room temperature and with a constant level of moisture and the properties of the concrete were examined. The properties investigated include compression strength, modulus of elasticity, elastic and creep strain, creep recovery, creep coefficient.
