Simply put, pozzolans improve concrete by converting problem-causing Calcium Hydroxide (CH)—a by-product of the hydraulic reaction between water and cement powder—to additional Calcium Silicate Hydrate (CSH)—the glue that binds the concrete aggregate. The true wonder of the pozzolanic reaction is that it both consumes the source of the problem and repurposes it to desirable CSH. The ...
