FIELD: manufacture of building materials.
SUBSTANCE: invention relates to compositions of dry mortar mixes based on cement binder and mineral aggregate such as sand intended to prepare finishing mortars and manufacture cast-in-place floors. Dry building mix including cement (27-35%), sand fractions ≤0.63, 0.63-1.25, and 1.25-2.5 mm wherein proportion of each fraction is not higher than 37% of the total weight of sand, and superplasticizer C-3 (0.125-0.180%) further contains carbon white BS-120 in the same amount as superplasticizer (0.125-0.180%).
EFFECT: increased flowability of mortar mix at lower water-to-cement ratio and improved laying ability of mix resulting in better quality of operation.
