| Uses |
Use for ready-mix concrete ,pumping concrete,mass concrete,high appreance requirement concrete and other high performance concrete with high durability requirement |
Use in all kinds of high performance concrete which has early strength requirment, such as routine maintenance ready-mix concrete member,railway,highway,birdge,port and industrial architecture and so on |
Use together with polycarboxylate superplasticizer (PCE) in high performance concrete |
Use for PHC pile concrete ,subway concrete segment, pole concrete or other high performance concrete with high vapor-cured requirement |
