摘要

Self-compacting concrete (SCC) is one of the most significant advances in concrete technology over the past two decades. SCC was developed to ensure adequate compaction through self-consolidation and facilitate placement of concrete in structures with congested reinforcement and in restricted areas. This paper aims to focus permeability study of self-compacting concrete (SCC) made with industrial wastes, i.e., marble sludge powder (MSP) from marble processing and crusher rock dust (CRD) from stone crushing industries. MSP can be used as filler and it helps to reduce the total voids content in concrete. Consequently, this contributes to improve the strength of concrete. An experimental investigation has been carried out to study the combined effect of addition of MSP and CRD on the durability of SCC. Water absorption, water permeability (flow), Ionic flow (Rapid Chloride ion penetrability) tests were conducted to measure the permeability of SCC and the results were compared with the normal concrete made up of river sand (NCRS) and the normal concrete made up of CRD (NCCRD). Test results indicate that the replacement of river sand with MSP and CRD in SCC reduces the permeability and does not affect the compressive strength.
