The dry matter content in the VDP is not less than 40% by mass, its conservative viscosity according to the VZ-4 viscometer at 20 ° C is 12–23 s.
Приготовление композиции дл отделки поверхностей осуществл ют следующим образом.The preparation of the surface finishing composition is carried out as follows.
Дл получени отделочного раствора однородной консистенции (без признака расслоени ) компоненты в заданных соотношени х загружают в турбулентный смеситель СБ-43 в следующей последовательности: ВДП, вода, цемент, молотый шлак, ВНВ и мелкий кварцевый песок. Длительность перемешивани сырьевых ингредиентов в смесителе после загрузки не превышает 5 мин. Рабоча консистенци раствора находитс в пределах 20-22 см расплава на вискозиметре Суттарда,In order to obtain a finishing solution of a uniform consistency (without the sign of stratification), the components at given ratios are loaded into a SB-43 turbulent mixer in the following sequence: VDP, water, cement, ground slag, VNV, and fine quartz sand. The duration of mixing the raw ingredients in the mixer after loading does not exceed 5 minutes. The working consistency of the solution is in the range of 20-22 cm of melt on the Suttard viscometer,
Примеры составов композиции дл отделки поверхностей и основные технические свойства покрытий приведены в таблице.Examples of compositions for surface finishing and basic technical properties of coatings are shown in the table.
Наличие в составе ВНВ суперпластификатора , тонкий помол клинкера до удельной поверхности 10 тыс. см2/г и добавки молотого шлака позвол ют при формировании полимерминерального покрыти усилить контракционные процесссы в цементном камне, увеличить объем капилл ров радиусом менее 10 - 10 см, которые в обычных атмосферных услови х участие в фильтрации влаги не принимают.The presence of a superplasticizer in a VNV composition, fine grinding of clinker to a specific surface area of 10 thousand cm2 / g and the addition of ground slag make it possible, during the formation of a polymer-mineral coating, to enhance the contraction processes in the cement stone, to increase the volume of capillaries with a radius of less than 10 to 10 cm, which in conventional atmospheric Conditions do not take part in the filtration of moisture.
Использование изобретени позвол ет получить эффективное отделочное покрытие с повышенной морозостойкостью и водонепроницаемостью , решить проблему утилизации доменного шлака, а также снизить себестоимость покрыти .The use of the invention allows to obtain an effective finishing coating with increased frost resistance and water resistance, to solve the problem of utilization of blast furnace slag, as well as to reduce the cost of coating.
