<p><P>PROBLEM TO BE SOLVED: To provide a method of manufacturing autoclaved lightweight concrete (ALC) by using a low grade inexpensive siliceous raw material to homogeneously form a large quantity of tobermorite having high crystallinity and properly keeping the viscosity of raw material slurry. <P>SOLUTION: In the ALC manufacturing method by using each powder of the siliceous raw material and a calcareous raw material as main raw materials, adding aluminum powder and water into the raw main materials, kneading to form slurry and pouring the slurry into a molding flask, foaming, hardening, cutting the resultant semi-hardened body and curing under a high temperature high pressure steam atmosphere; silica sand and/or silica stone containing≤15 wt.%, preferably 1-12 wt.% feldspar is used as the siliceous raw material. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
