有效利用工业废渣制备混凝土高效膨胀剂的研究

Research on the Preparation of High Effective Expansive Agents for Concrete Using Sulphate Waste Residue

介绍了利用工业生产过程中生成的含硫废渣,部分取代膨胀剂膨胀组分中的天然硬石膏,制备混凝土高效膨胀剂,从而研究工业废渣取代量和形态对其限制膨胀率、抗压强度、凝结时间等性能的影响。

Aiming at the preparation of high effective expansive agents for concrete, the natural anhydrite in expansive agents was substituted in part for the waste residue produced in the process of industrial production. And the influence of replacements and shape on the confined expansion, the compressive strength and the setting time was studied.
