AAC-J is premix mortar for jointing and bonding of AAC blocks, panel, concrete blocks, hollow blocks, clay bricks and fly ash bricks. AAC-J consists of cement, graded sand and specialized polymers, which combine to give superior adhesion strength, water retention and stability. It replaces the conventional method and material of jointing mortar, which requires a 12-20 mm thickness with a revolutionary 2-5 mm joint thickness. It is mixed with water to make adhesive
