    This paper addresses the efficiently reuse of the recycled construction waste cementitious materials (RCWCM). The RCWCM is firstly collected, and then subjected to crushing, grinding and thermal treatments, respectively. After that, the obtained powder material is named dehydrated cement paste (DCP) in this study. Due to the fact that the DCP has relatively high pH value and high activity, two specific attempts are tried to efficiently reuse the obtained DCP. The results show that it is possible to produce a prefabricated building material with an industry by-product (fly ash) and a recycled waste material (DCP). The compressive strength of the produced prefabricated building material can be higher than 60 MPa. Additionally, after being further dispersed, the DCP could be utilized as a high performance cement additive, which can significantly promote the hydration and microstructure development of cement.
