UTC mortar is a semi premix high quality mortar for jointing and bonding of AAC blocks, concrete blocks, hollow blocks, clay bricks and fly ash bricks. UTC mortar semi premix consists of cement, graded sand and specialised polymers which combine to give superior strength, water retention and stability. It replaces the conventional method and material of jointing mortar which requires a 12-18 mm thickness with a revolutionary 2-3 mm joint thickness. UTC mortar only requires addition of water before application to prepare the product for use, reducing the hassle of measuring and maintaining various individual elements to create a conventional mortar. Standard specification code followed is ASTM C1660-09.
