<p>The invention provides a lightweight cementitious mixture comprising by volume: 5 to 80 % cement, 10 to 65 % expanded polystyrene particles; 10 to 90 % expanded mineral particles; and water sufficient to make a paste with a substantially even distribution of expanded polystyrene after proper mixing. The combination of expanded polystyrene particles and expanded mineral particles, such as of perlite and/or vermiculite, enables homogeno us, repeatable mixing to occur. Thus products with stable, expected properties can be produced for a range of structural and non-structural applications.</p> |
