摘要
主要研究了双掺技术(掺加粉煤灰和减水剂)和三掺技术(掺加粉煤灰、减水剂和矿渣粉)对混凝土性能的影响。通过双掺技术和三掺技术拌制不同强度混凝土的性能规律比较,分析矿物外加剂和减水剂对混凝土的作用机理,根据不同工程需要,需要慎重选择双掺技术和三掺技术。
The effects of double-doping technology(adding fly ash and water reducing agent)and triple-doping technology(adding fly ash,water reducing agent and slag powder)on the performance of concrete were mainly studied.By comparing the performance rules of different strength concrete mixed with double-doping technology and triple-doping technology,the mechanism of mineral admixtures and water-reducing agent on concrete was analyzed.According to the needs of different projects,it is necessary to carefully select double-blending technology and triple-blending technology.
