Recently, as new concept concrete such as fiber reinforced concrete and ultra high early strength is widespread rapidly in construction industries and they have reached commercialization. However, compared to development of concrete performance, production, placement and curing conditions are insufficient for the study. In particular, the strength development of concrete is different according to the order of material addition in the concrete mixer. So, this paper focuses on the effect of mixing method on the mechanical properties of concrete. In this work test is conducted according to sequence of materials using concrete twin mixer.
