FIELD: construction.
SUBSTANCE: invention concerns manufacture of construction materials, in particular, to complex additives in concrete mixes and can be used at production of concrete and water mortars with different functions. Complex additive for concrete and the water mortars including amorphous and/or crystal silicon dioxide, derivant of higher fatty acids, super-plasticiser of naphthalene formaldehyde type, contains as derivant of higher fatty acids - oligomers of higher fatty acids of lapromol production, and, as super-plasticiser of naphthalene formaldehyde type - Polyplast "СП-1" super-plasticiser at following ratio of components, mass %: specified super-plasticiser - 46.0-97.5, oligomers of higher fatty acids of lapromol production - 0.01-0.1, amorphous and/or crystal silicon dioxide - the rest.
EFFECT: increase in movability of concrete mixes and increase of durability of concrete and water mortars.
