Method for forming foamed concrete structures
Abstract
Abstract CELLULAR CONCRETE STRUCTURES ARE MADE BY ADMIXING WATER AND CEMENT UNDER CONDITIONS SUFFICIENT TO PRODUCE A HIGH DEGREE OF HYDRATION OF THE CEMENT PARTICLES, FOLLOWED BY THE INTRODUCTION OF A FOAM FORMED UNDER PRESSURE FROM A MIXTURE OF WATER, AIR, FOAMING AGENT AND CHLORIDE ACCELERATOR. THE FOAM MIXTURE AND CEMENT ADMIXTURE ARE BLENDED TO A SUBSTANTIALLY HOMOGENEOUS, FOAMED CEMENT SLURRY, WHICH IS CAST INTO A MOLD AND CURED TO FORM A LIGHTWEIGHT CELLULAR CONCRETE STRUCTURE. IN THE STRUCTURE, THE VOIDS ARE RELATIVELY SPHERICAL IN SHAPE AND HAVE AN AVERATE DIAMETER OF ABOUT 0.05 TO 0.050 INCH. THE FOAMING AGENT AND CURE ACCELERATOR ARE CONCENTRATED AT THE SURFACE OF THE CONCRETE MATRIX ABOUT THE VOIDS, AND THE STRUCTURE HAS A UNIFORM DENSITY OF ABOUT 25 TO 75 POUNDS PER CUBIC FOOT.
