利用磷石膏研制混凝土高效膨胀剂

Using Phosphor-gypsum to Develop Concrete High Performance Expansive Agent

本文介绍了利用工业废弃物磷石膏煅烧脱水制取硬石膏,再与特制高铝熟料配合研制混凝土高效膨胀剂。

This article introduces a method of manufacturing high-effective expansive agent for concrete. This type of expansive agent is produced by corporating specially-produced clumious clinker with anhydrite which can be achieved by firing ardealite (one of industrial wastes) and losing water in it.
