Abstract
A cement product including a supplementary cementitious material (SCM) including natural aluminosilicate, and optionally metakaolin, and methods of producing the cement product, and methods of use thereof are provided. The natural aluminosilicate may have, for example, a d97 less than or equal to about 19 μm; and may have a d10 less than or equal to about 2 μm. The product may also have improved chloride permeability as compared to cement products including natural aluminosilicates having higher d97 and d10 values. Also, the product may also have improved compressive strength and RCPT values when a portion of the natural aluminosilicate in the SCM is replaced with metakaolin.
