摘要
本文介绍了陕西电信网管大楼工程2.5m后基础底板大体积混凝土,采取掺加粉煤灰和膨胀剂,并用60d为抗压强度验收龄期等施工技术措施,控制大体积混凝土的温度裂缝。工程未发现温度裂缝。
This article introduced mass concrete foundation slab in Shanxi telecommunication network managementbuilding project which is 2.5m. We tried to control the temperature cracks of mass concrete through the mixing of thepulverized coal ash and the expensive agent, and achieving the compressive strength 60 days later. We didn’t findthe temperature cracks during the construction.
