A composition comprising:
- a low density lightweight gypsum or cementitious mix comprising low density lightweight mineral based particles with compressive strengths of greater than 2,000 psi and densities within a range from about 55 pcf to about 95 pcf.
A composition comprising:
- an ultra low density lightweight gypsum or cementitious mix comprising low density lightweight polymer based particles with compressive strengths of greater than 50 psi and densities within a range from about 15 pcf to about 55 pcf.
A gypsum or cementitious mixture having a density of less than about 130 pcf and having a controlled working or set time of at least 60 minutes to enable the delivery of the system via a mixer truck, pump truck, bulk truck or ready mix truck.
