WATERPROOF MORTAR COMPOSITION AND METHOD FOR PREPARING SAME

摘要

The present invention relates to a waterproof mortar composition, which can exhibit an excellent adhesive performance with conventional concrete and maintain good workability, and obtain a required strength in a short time such that the composition is suitable for repairing a deteriorated or partially damaged defective part of the road and shows an effective waterproof property for structures including a road. The waterproof mortar composition, according to the present invention, comprises: 15-40 wt % of preprocessing silica; 25-45 wt % of an inorganic binding material; 15-25 wt % of silica; 5-10 wt % of phosphate; 2-10 wt % of aluminum oxide; and 2-10 wt % of magnesium oxide. According to the elements of the waterproof mortar composition, the present invention is capable of preventing cracks and separation of the construction part; and improving the adhesion with an attachment and at the same time, improving waterproof efficiency by filling a silane-based resin in an air-tight manner.
