A process for producing micropellets of lightweight aggregate having a substantially spheroidal configuration which includes continuously mixing ceramic clay and liquid in a high speed rotating pin mixer to encapsulate substantially all other non-volatile inorganic solid materials present in micropellets having a diameter not exceeding about six mesh. The spheroidal micropellets are then fired at a temperature of at least 2,000 DEG F. to oxidize all volatile organic compounds present. The light-weight aggregate of micropellets can advantageously-be used to replace sand in a cement or concrete matrix, as a well as for numerous other uses.
