Abstract Currently, chemical attacks, including acid attacks and sulphate pose a significant problem for the long-term durability of concrete infrastructures that encounter many types water, swamp marine sewage drinkable groundwater. Therefore, intention this work is to enhance resistance against attack by blending titanium dioxide (TiO 2 ) as nanoparticles into designed cementitious composites. The purpose current study obtain an appropriate TiO based on cement’s weight polyvinyl alcohol (PVA) fiber in composites using multi-objective optimisation. Thirteen mixtures comprising diverse combinations variables : 1–2%, PVA: 1–2%) were formulated utilising RSM modelling. Seven responses assessed these mixtures, loss, compressive strength, expansion, rapid chloride permeability test (RCPT) pH test. Analysis variance, other hand, was utilised construct assess eight response models (one linear six quadratics nature). R values spanning from 88 99%. optimisation generated optimal ideal variable (1% PVA 1.5% ). Experimental verification revealed predicted correlated exceedingly well with experimental data, error rate less than 5%. outcomes indicate 30% rise strength noted when nanomaterial incorporated ECC. Furthermore, expansion caused decreases used increases Besides, concentration ECC increased, value, loss reduced. In addition, RCPT recorded reducing content but it addition fiber. It has been shown 1% yields results building sector.
