Supplementary Cementitious Materials

Supplementary Cementitious Materials by Ghani Khan explores the role of fly ash, slag, silica fume, and other mineral additives in enhancing the performance and sustainability of concrete. The book blends technical insights with practical construction applications, making complex material science accessible to builders, designers, and students alike. It highlights how SCMs not only reduce CO₂ emissions but also improve durability, workability, and long-term strength in residential and commercial projects. In his own residential project in DHA Phase 2, Islamabad, Ghani Khan demonstrated this principle by using 5% fly ash as a cement replacement, cutting nearly 5 tons of CO₂ emissions.
