Fire resistant coating and high strength, density controlled cold fusion concrete cementitious spray applied fireproofing
Disclosed is a densitycontrolled, geopolymer concrete, sprayapplied, fireproofing material that is designed to meet a desired target density with low shrinkage and good bond strength upon curing. The formulations are useful for treating architectural structures to impart fire resistance with industrial byproducts and without the associated environmental impact of carbon dioxide and greenhouse gases associated with other cements. Importantly, the compositions include a sacrificial and lightweight particle system that dissipates temperatures during 1, 2, 3, and 4-hour exposures to 2,000 F (1093 C), without experiencing a temperature of greater than 999 F (537 C) to underlying structure during the exposure period and even lower temperatures with greater thicknesses on less durable substrates such as wood and concrete.
