Nuruddin %V 201 %T Optimisation of nano-silica modified self-compacting high-Volume fly ash mortar %X Evaluation of the effects of nano-silica amount and superplasticizer (SP) dosage on the compressive strength, porosity and slump flow on high-volume fly ash self-consolidating mortar was investigated. Multiobjective optimisation technique using Design-Expert software was applied to obtain solution based on desirability function that simultaneously optimises the variables and the responses. A desirability function of 0.811 gives the optimised solution. The experimental and predicted results showed minimal errors in all the measured responses. © Published under licence by IOP Publishing Ltd. %K Compressive strength; Fly ash; Mortar; Multiobjective optimization, Design-expert; Desirability function; High volume fly ash; Minimal errors; Nano Silica; Optimisations; Self-compacting; Superplasticizers, Silica %J IOP Conference Series: Materials Science and Engineering %L scholars8618 %O cited By 2; Conference of 7th International Conference on Key Engineering Materials, ICKEM 2017 ; Conference Date: 11 March 2017 Through 13 March 2017; Conference Code:128371 %N 1 %R 10.1088/1757-899X/201/1/012013 %D 2017
