What is the details of our plastic refractory?

Plastic refractory is made by refractory aggregate,powder,binder and admixture.It has good work performance and plasticity. According to America ASTM,plastic refractory’s plasticity index is more than 15%,castable refractory’s plasticity index is less than 15%.In China, plastic refractory’s plasticity index is between 15%-40%.
