Description
Изобретение относитс к промышленности строительных материалов и может быть использовано дл приготовлени золосодержащих бетонных смесей с добавками суперпластификаторов.The invention relates to the building materials industry and can be used for the preparation of ash-containing concrete mixes with the addition of superplasticizers.
Целью изобретени вл етс повышение подвижности, снижение водосодер- жани и расхода цемента.The aim of the invention is to increase mobility, reduce water content and cement consumption.
Пример. Золу-унос с удельной поверхностью 4280 смг/г в количестве 5 кг ввод т в шаровую мельницу и размалывают в присутствии 20 г водного раствора добавки супера:астификатора (0,135 % от массы золы-унос. в пересчете на сухое вещество при концентрации сухого вещества 35%). Удельна поверхность продукта помола 6890 см2/г. Продукт помола в коли- честве 1,2 мае.ч. от массы цемента ввод т в бетономешалку и смешивают с цементом, кварцевым песком с модулем крупности 1,9, гранитным щебнем фракции 5-20 мм и водой затворени , содержащей добавку суперпластификатора.Example. Fly ash with a specific surface of 4280 cmg / g in an amount of 5 kg is introduced into a ball mill and ground in the presence of 20 g of an aqueous solution of the additive of the super: astifier (0.135% by weight of fly ash. Calculated on the dry matter at a dry matter concentration of 35 %). The surface area of the grinding product is 6890 cm2 / g. The grinding product in the amount of 1.2 mach. from the mass of cement is introduced into the concrete mixer and mixed with cement, silica sand with a grain size module of 1.9, granite rubble of a fraction of 5-20 mm and mixing water containing a superplasticizer additive.
Общин расход добавки суперпласшфика- тора в бетонной смеси 0,8 % от золыThe community consumption of the supersolvate additive in the concrete mix is 0.8% of ash
После перемешивани компонентов до получени однородной смеси определ ют подвижность бетонной сиеси по осадке конуса с точностью до 0,5 см. Из полученной бетонной смеси формуют образцы-кубы, которые хран 1 Б нор- альных услови х в течении 28 сут, п затем определ ют прочность при сжатии ,After mixing the components until a homogeneous mixture is obtained, the mobility of the concrete mix is determined by the cone sediment with an accuracy of 0.5 cm. From the obtained concrete mixture, cubic samples are formed, which are stored for 1 day under normal conditions for 28 days, then compressive strength
