Developments in High-Performance Concrete Technology within the Saudi Arabian Construction Industry

This study aims to develop High-Performance Concrete (HPC) using materials readily available in local markets within the Kingdom of Saudi Arabia (KSA). The primary objective is to achieve compressive strengths exceeding 70 MPa by optimizing concrete mix designs through a series of experimental trials. The methodology involves incorporating varying percentages of silica fume (SF) as a mineral admixture alongside locally sourced aggregates, including crushed stone and quartz sand. The paper focuses on evaluating the effect of silica fume concentration on key performance indicators of HPC: compressive strength, permeability, and workability. Experimental results demonstrate that producing HPC with compressive strength above 70 MPa is achievable using local materials, provided they are carefully selected and proportioned to ensure optimal particle packing and mix uniformity. HPC performance improves with increasing silica fume content up to 20–30%, balancing strength, durability, and workability. Mix C (20% SF) offers an optimal combination of high compressive strength, low permeability, and reasonable workability.
