| Summary: | By-pass filter dust (BPD) is one of the main by-products produced and collected during the cement production process, being a potential atmospheric and subsoil pollutant. In this paper, the utilization of BPD by partially replacing a conventional filler such as marble powder with regard to the durability and transport properties of Self-Compacting Concrete (SCC) is thoroughly investigated. More specifically, BPD’s incorporation effect was evaluated after conducting a series of tests related to SCCs’ water absorption, sorptivity, water permeability, chloride diffusion coefficient, carbonation and freeze and thaw resistance. The above-mentioned test results demonstrated that BPD, thanks to its high pozzolanic reactivity in conjunction with its filler effect, contributed to the production of SCC of a denser cementitious matrix, which, in turn, lead to improved durability. |
