An aqueous resin dispersion for mortar according to the present invention comprises: a polymer (A) which is obtained by polymerizing 0.1 mass% to 5.0 mass% of an alkoxysilane group-containing polymerizable monomer (a), 0.5 mass% to 3.0 mass% of a carboxylic acid group-containing polymerizable monomer (b), and another polymerizable monomer (c) which copolymerizes with the component (a) and the component (b), and which has a calculated glass transition temperature of -20°C to 20°C; and a nonionic surfactant. L'invention concerne une dispersion de résine aqueuse pour mortier qui comprend : un polymère (A) qui est obtenu par polymérisation de 0,1 % en masse à 5,0 % en masse d'un monomère polymérisable contenant un groupe alkoxysilane (a), de 0,5 % en masse à 3,0 % en masse d'un monomère polymérisable contenant un groupe acide carboxylique (b) et d'un autre monomère polymérisable (c) qui copolymérise avec le constituant (a) et le constituant (b), et qui a une température de transition vitreuse calculée allant de -20°C à 20°C ; et un tensio-actif non ionique.
