The compatibilities of slag with amphoteric superplasticizer

Li Juan;Zhang Haijiao;Zhang Liran;Hao Bing;Wang Dongmin;China University of Mining &Technology;  
Different dosage of slag concrete, were mixed with two kinds of water reducing agent – anionic superplasticizer(PCan) and amphoteric superplasticizer(PCam). The amount of cement replaced by slag is 10%~50%. Slump was designed in(200±10)mm, the concrete stage and hardening stage performance were tested and the PCam compatibility with slag was discussed. Results show that water use can be effectively reduced by superplasticizer, water reducing rate is more than 30%, PCam can effectively improve the early strength, increase the strength of more than 15%。
