摘要：

This paper presents outcomes of investigation on various durability properties of engineered cementitious composites (ECC) incorporating glass powder as the cementitious material. The Durability was evaluated by assessing the shrinkage, permeability, and alkali-silica reaction resistance of the ECC mixtures. Shrinkage properties investigated are plastic, autogenous and drying shrinkage. The permeability properties evaluated are porosity, water absorption, sorption, sorptivity and chloride ion penetration. Results from this study showed that glass powder can be used to significantly reduce the shrinkage of ECC mixtures, however, there is a negative effect on its permeability properties. On the positive side, no occurrence of the alkali-silica reaction was observed in any ECC mixtures incorporating glass powder. Based on the overall performance of ECC mixtures incorporating glass powder, the replacement of 25% fly ash with glass powder was found to be the optimum. (C) 2020 Elsevier Ltd. All rights reserved.
