High Alumina Refractory Mortar Unshape Refractory Products
The Description:
High alumina refractory mortar (KHLN-55) is made of high bauxite clinker, binder and admixture, usually delivered in bulk dry, and mixed with water when used.
Solemnly remind: refractory mortar and refractory cement are different, refractory mud is mainly used as a joint material or brick joint material for masonry refractory bricks, and the adjusted refractory mud is also called refractory mud; Refractory cement is used to make refractory castable or refractory plastic bond, refractory cement is also known as high aluminum cement or aluminate cement.
