Preparation of an Environment Friendly Adhesive Mortar

In this paper, a new polymer-modified adhesive mortar is prepared using the fine iron tailings, eco-cement, re-dispersible latex powder, additives and water. In the preparation, the fine iron tailings are used to replace the river sand as the mortar aggregate. The Orthogonal experiment is designed to determine the optimal process conditions. The obtained results are as follows: the cement-sand ratio is 1:2.5, polymer-cement ratio is 4 %, the aggregate modulus is 0.81, and water reducing agent is 0.5 % (cement based). The properties of obtained polymer-modified adhesive mortar in the optimal process conditions conform to JC/T 547-2005 (The China Professional Standard: Ceramic Tile Adhesive).
