Portland Slag Cement, commonly known as PSC, is blended cement. Slag is, essentially, a non-metallic product comprising of more than 90% glass with silicates and alumino-silicates of lime. PSC has been voted as the most suitable cement for mass construction because of its low heat of hydration.
Why do we test concrete?
Fresh concrete tests measure factors such as strength, consistency, unit weight, air content, and temperature. By performing such tests consistently, you can detect changes in concrete that may affect its long-term performance.
What is the ratio of concrete mix?
