Optimization, microstructure, and durability of sawdust ash concrete modified with Conplast SP430 superplasticizer

The use of sawdust ash (SDA) as a supplementary cementitious material offers an opportunity to valorize biomass waste and reduce dependence on Portland cement, but its incorporation can affect workability, strength development and durability. This study investigates the combined effects of SDA replacement and Conplast...

Microstructural characterization, response surface modelling and multi-objective optimization of water hyacinth fibre-reinforced concrete

This study investigates the combined influence of water hyacinth fibre content (wt. % of cement) (0.5–2.0%) and fibre length (10–50 mm) on the water absorption (WA), density, and compressive strength (CS) of concrete using response surface modelling and multi-objective optimization. A replicated full-factorial experime...
