🧪 WHY ARE ADMIXTURES ADDED TO CONCRETE? Admixtures are special chemical or mineral ingredients added to concrete (apart from cement, sand, aggregate, and water) to improve its performance. They are used in small quantities but have a big impact on concrete quality. 🧱 Main Purpose of Adding Admixtures ✔️ To increase durability ✔️ To increase strength ✔️ Sometimes to increase workability These improvements help concrete perform better under different site and environmental conditions. 🏗️ TO INC

Modern researchers have discovered that ancient Roman concrete behaves very differently from today’s materials, especially when exposed to water and stress. Instead of degrading, it can actually become stronger over time. The secret lies in the unique mineral composition of Roman concrete, which reacts with seawater to form new crystalline structures that naturally seal cracks. This self-healing behavior explains why many Roman structures still stand after nearly 2,000 years. From an environment
