KMI Zeolite Natural Pozzolan is an alternative cementitious material with unique pozzolanic properties.
KMI Zeolite is a powerful and abundant natural pozzolan with benefits including a reduction of alkali-silica reactivity and reduction in the total carbon footprint of concrete.
Our zeolite has a high surface area and cationic exchange capacity, making it a suitable pozzolanic material. It is available as raw ore, direct from the deposit, ready to be crushed on-site at most cement plants. Or, it it is also available, as a air-classified particle size of <34% retained on a no. 325 mesh sieve, pursuant to ASTM C 618.
KMI Natural Pozzolan can be used as a partial cement replacement or in binary or ternary mixes with fly ash and or slag cement.
Available as run of mine ore, or milled to spec. <34% retained on no. 325 mesh.
KMI Natural Pozzolan is compliant with ASTM C 618 and AASHTO M 295 and is source-qualified for use in ready mix concrete.
KMI Natural Pozzolan is listed on the CALTRANS Authorized Cementitious Materials for use in concrete.
