Abstract
High-performance concrete appears to be a good choice for strong and durable reinforced concrete structures. Suitable addition of mineral admixture can improve the strength and durability owing to improvement in the microstructure at the transition zone. This paper presents an experimental study on the mechanical properties and durability of high-performance concrete containing porcelain waste powder. Concrete mixes possessing a target mean compressive strength of 70 MPa were prepared with 5%, 10%, 15% and 20% cement replacement by porcelain waste powder (water-to-binder ratio, W/B = 0·33). The mechanical and durability performance of porcelain waste based concrete is assessed by means of mechanical, rapid chloride penetration, accelerated corrosion and sorptivity tests. Results show that concrete mixtures with 15% porcelain waste perform better than the control mixtures in relation to compressive strength, flexural strength, chloride penetration, corrosion and sorptivity. Replacement by porcelain waste powder also has major environmental benefits.
