Designer, Software Engineer, and Art Director in US
A Pozzolan, as defined by ASTM, reacts chemically with calcium hydroxide produced by the hydration of Portland cement to form additional cementations compounds. STERLING ASH Class F Fly Ash significantly increases the ability of concrete to resist attack from sulfates in soil or ground water. Additionally, Class F fly ash has been proven through extensive research and field experience to be highly effective in mitigating the deleterious effects of unrestrained alkali-silica reactions (ASR) in concrete
