Abstract
Изобретение относитс к технологии бетонных и железобетонных изделий на шлаковых заполнител х с добавками. Направлено на повышение удобоукладываемости и нерасслаиваемости бетонной смеси, а также прочности бетонов на мелком заполнителе из гранулированного фосфорного шлака. В смеситель загружают плотный крупный заполнитель (щебень или гравий) и мелкий заполнитель из гранулированного фосфорного шлака и часть воды с СДБ и перемешивают в течение 1,5 - 2,0 мин. При этом количество воды определ етс исход из водопоглощени заполнителей. Затем ввод т цемент и остальную воду затворени , в которую ввод т добавку - сточный продукт производства витамина Е. 1 табл.This invention relates to the technology of concrete and reinforced concrete products on slag aggregates with additives. It is aimed at improving the workability and non-separability of the concrete mix, as well as the strength of concrete on a fine aggregate of granular phosphorus slag. A dense coarse aggregate (crushed stone or gravel) and fine aggregate from granulated phosphorus slag and a part of water with DL are loaded into the mixer and mixed for 1.5-2.0 minutes. The amount of water is determined by the water absorption of the aggregates. Then, cement and the rest of the mixing water are introduced, into which the additive, a waste product of vitamin E production, is introduced. Table 1.
Description
занной температуре и 3 ч - охлаждение в камере. Подвижность бетонной смеси, расслаиваемость и прочностные характеристики определ ют по ГОСТу. temperature and 3 hours - cooling in the chamber. The mobility of the concrete mix, the stratification and strength characteristics are determined according to GOST.
Прочностные характеристики по известному способу через 28 сут на сжатие составл ют 33,5 МПа, на изгиб 5,9 МПа.Strength characteristics by a known method after 28 days of compression are 33.5 MPa, bending 5.9 MPa.
Результаты испытаний представлены ю в таблице.The test results are presented in the table.
