AGGREGATE, METHOD OF MANUFACTURING THE SAME, AND MORTAR/CONCRETE FOR SPRAYING

摘要

PROBLEM TO BE SOLVED: To easily obtain aggregate capable of advancing an alkali aggregate reaction without obstructing the hardening performance even in use of mortar/concrete rich in the unit quantity of cement such as mortar/concrete for spraying making a slope or the like having large inclination application objects and the mortar/concrete having properties suitable for the spray application to stabilize the inclined surface of the slope or the like without degrading for a long period of time. SOLUTION: The aggregate is porous aggregate having opened void wherein lithium nitrite is incorporated. The mortar/concrete for spraying contains cement and the porous lightweight aggregate having the opened void in which lithium nitrite is contained. COPYRIGHT: (C)2006,JPO&NCIPI
