Abstract: Green building materials are new functional building materials with degaussing , noise elimination, attemperation, humidity-controlling, heat insulation, fire resistance and antistatic property , they focus on human health and environmental protection and are important development direction of new materials in the future . Our country is rich in natural sepiolite resources , because it has many advantages , such as its large surface area , good moisture absorption and desorption , strong adsorption , flame retardant and heat insulation , high temperature resistance , salt tolerance and good rheological properties , sepiolite especially suitable for humidity-controlling material , fireproof material , air purification material , energy-saving insulation material and cement-based material and so on .According to the current research and application of sepiolite building materials at home and abroad , this paper summarizes the composition , yield, properties of sepiolite and feasibility and action mechanism of its application in several green building materials .At the same time , it also puts forward the existing problems, and has better theoretical guiding significance on reasonable application of sepiolite in functional green building materials .
