摘要
对于中东地区燥热环境下,混凝土坍落度损失快的特点,采取在混凝土中掺入预先吸水的超吸水树脂(Super absorbent polymer,简称SAP)、增加减水剂用量等措施改善混凝土坍落度经时损失。结果表明:掺SAP和增加减水剂用量对当地的两种配合比混凝土坍落度损失有显著改善作用。
For slump loss of concrete quickly under hot and dry environment in Middle East, the slump loss was im proved by mixed with pre-absorbent super absorbent polymer （SAP）, increased superplasticizer quantity in the con crete. The results show that slump loss was significantly improved with these measures.
