Zusammenfassung:	PURPOSE: To make specific gravity low, to eliminate the generation of material separation caused by the floating of an aggregate and to improve strength and trowel finishing property by kneading cement, a specific super lightweight aggregate, a ceramic lightweight foamed material of a completely closed hollow spherical body and water. CONSTITUTION: This super lightweight concrete composition is obtained by kneading 100 pts.wt. cement, 10-100 pts.wt. super lightweight aggregate obtained by granulating and firing a porous biotite rhyolite fine powder and having specific gravity of 0.5-1.20 in absolute dry condition and 0.6-5mm particle diameter, 5-50 pts.wt. ceramic lightweight foamed material of the completely closed hollow spherical body having
