Lightweight mortar used for e.g., floors in buildings, has mixture of cement, aggregate, and surfactant, in which aggregate consists of sand and ground polyurethane residues, and ground polyurethane residues and sand

Abstract

The mortar has a mixture of cement, aggregate, and between 0.5-50 wt. % of one surfactant in relation to the weight of cement. The aggregate consists of sand and ground polyurethane residues, and between 25 and 100 vol. % of the aggregate is ground polyurethane residues and sand. The surfactant is an electrically conductive compound, and has a lower hydrolipophil radius or equal to 16. The resistance to the variation in density has the capacity to attain a resistance value at a maximum pressure of between 35-50 MPa at 28 days. USE - Lightweight mortar used for e.g., floors in buildings, interior and exterior walls, and filling of structures. ADVANTAGE - The mortar has lighter material which has a very positive effect on the reduction of the load that is added to the structure on which a building is being worked or laid. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for obtaining a lightened mortar.
