Abstract: A powder adhesive composition having cement, a dispersible polymer powder; and at least 10% volume of the powder adhesive is an expanded perlite. The cement is at a ratio of between 600-1000% of the mass of the expanded perlite. The powder adhesive composition is an adhesive, and the adhesion strength of the adhesive, is over 0.4 MPa, after 28 days, and after water immersion for at least 20 days.
