摘要: A cement composition for use in acidic environments containing an acid resistant particulate aggregate of fused mullite aggregate or other aggregate material, with quartz, and microsilica in combination with a colloidal silica sol binder and being substantially free of Na compounds and K compounds which react in the presence of sulfuric acid to form alkali sulfates in service, thus reducing the durability or the service life.
