Blakite Mortar
It is a highly refractory mortar of a dark grey colour, which has the property of good water binding. It has been especially developed for laying of heat resistant insulating bricks, but it is also suitable for use with highly refractory and high alumina bricks at working temperatures up to 1650°C. It is produced in a consistency suitable for thin joints and filling but requires the addition of approximately 5% dipping water. Blakite is a good solution as a single mortar for general purpose applications in projects using mainly insulating refractory bricks and heavy refractory bricks.
