<p>PURPOSE:To manufacture a high performance concrete aggregate with no expansion in a short period and also to evade the influence due to the particle size of the steel slug and the expansibility by using a steel slug as the raw material. CONSTITUTION:The steel slug 4 preliminarily adjusted the particle size is aged in a steam atmosphere. Free lime remaining in the steel slug 4 is completed a hydration reaction in a short time and the volume of the expanded slug 4 is stabilized. The steam aging exhibits a stable aging effect for the steel slug of various particle sizes and different expansibilities.</p> |
