摘要
A mortar composition for preventing inter-floor noises is provided to need no step of adding a separate noise-protecting layer on a concrete slab, and to realize excellent compression strength and impact noise-protecting effect. A mortar composition for preventing inter-floor noises comprises: 100 parts by weight of Portland cement; 10-30 parts by weight of styrene-butadiene synthetic rubber latex containing a mixed surfactant containing an anionic surfactant and a non-ionic surfactant in a weight ratio of 1:9-0:1; 20-400 parts by weight of waste tire powder; and 50-100 parts by weigh of sand, wherein 5-40 wt% of the mixed surfactant is used based on 100 wt% of the solid content of the styrene-butadiene synthetic rubber latex.
