摘要：

Engineered cementitious composites (ECC) is the new sort of cement mortar; it was basically designed with the combination of Portland cement, natural sand, class F fly ash, portable water, super plasticizer and 2% volume of short fiber. In the present scenario, the manufactured sand (M-sand) is the important ingredient for the preparation of cement mortar and cement concrete in construction due to the shortage of natural sand. This study concentrated on the influence of manufactured sand on the compressive strength of polyvinyl alcohol fibred-based ECC (PVA-ECC) with different types of mineral admixtures namely ground granulated blast-furnace slag (GGBS), fly ash, bagasse ash, rice husk ash (RHA), metakaolin and silica fume. The proportion of water/cementitious ratio and PVA fiber were kept constant of 0.3 and 2% of volume respectively for all mixes. To develop this mixture, mineral admixtures were added in PVA-ECC at different ratios such as 10, 20 and 30%. The experimental result exhibited that PVA-ECC with GGBS, fly ash, bagasse ash and metakaolin were produced satisfied compressive strength at 7 and 28 days compared to silica fume and rice husk ash. Also, the incorporation of different percentages of GGBS in the ECC Mix was produced higher strength at 7 and 28 days compared to control mix. © 2021, The Author(s), under exclusive licence to Springer Nature Switzerland AG.
