ABSTRACT:
A cementitious mixture including water-repellent vermiculite, polypropylene fibers and cement. A preferred embodiment utilizes: asphalt-coated, expanded vermiculite; collated, fibrillated polypropylene fibers; and non-shrinking Portland cement. Test data indicates a greatly increased compressive strength compared to previously known vermiculite insulating concretes. A prefabricated building panel utilizing the mixture of the present invention, and a method of manufacture thereof, are also disclosed. Calculated R values indicate good thermal insulating characteristics.
