Application :
High alumina refractory cement CA50,have passed the ISO international quality certifify.According to the different content of Al2O3,they can have totally foue types:CA50,CA60,CA70 and CA80.They have the advantage of longer setting time,can resist high temprature,better stability in air,rapidly strength,no addivity and suitable for confect all kinds of castables and low cement refractory castables,refractory concrete,ramming mixes, gunning mixes and manmade marble bricks etc.
