A METHOD FOR FORMING A RIGID, PERMANENT FLOATING CONCRETE MASS IN A BODY OF WATER COMPRISING THE STEPS OF INTRODUCING ONTO THE SURFACE OF THE WATER A CONCRETE MIX COMPOSITION CONSISTING ESSENTIALLY OF PORTLAND CEMENT AS THE BINDER AND HOLLOW, HOLE-FREE, GLASS SPHERES HAVING A DIAMETER OF FROM 5 TO 5000 MICRONS AND A GAS DENSITY OF FROM 0.1 TO 0.75 GRAM/CC. AS THE AGGREGATE, THE VOLUMETRIC RATIO OF BINDER TO AGGREGATE BEING WITHIN THE RANGE OF 1:3 TO 1:11, AND CONTAINING AT LEAST 0.5% BY WEIGHT A CATIONIC SURFACE-ACTIVE AGENT EVENLY DISPERSED THEREIN, AND PERMITTING SAID CONCRETE MIX TO SET IN PLACE WHILE FLOATING ON THE SURFACE OF THE WATER.
