PROPERTIES OF CONCRETE WITH A NEW TYPE OF AIR-ENTRAINING AGENT (TRADEMARK SJ-2)

摘要

SJ-2 air-entraining agent is introduced and the properties of concrete with this agent are investigated. The results show that the raw materials producing SJ-2 air-entraining agent and its characteristics are unique, and the properties of concrete with SJ-2 air-entraining agent are as good as those of concrete with the well-known Vinsol air-entraining agent. Therefore, SJ-2 air-entraining agent is an air-entraining agent with high quality that is worthy of recommending it to be used in concrete structures.
