Abstract
1. Способ приготовления бетонной смеси, включающий предварительную активацию золы гидроудаления ТЭС с частью воды затворения с последующим перемешиванием полученной зольной суспензии с цементом, заполнителями и оставшейся частью воды затворения, отличающийся тем, что золу гидроудаления ТЭС активируют при водотвердом отношении от 0,3 до 0,5, вначале при скорости соударения частиц 20,0-30 м/с и в течение 1,0-2,0 с, а затем в течение 2,0-3,0 с при скорости соударения частиц 35,0-45,0 м/с, а перемешивание полученной зольной суспензии с цементом, заполнителями и оставшейся частью воды затворения осуществляют при следующем соотношении компонентов, мас.ч.:2. Способ по п.1, отличающийся тем, что используют золу гидроудаления ТЭС следующего состава, мас.%:3. Способ по п.1, отличающийся тем, что в зольную суспензию при активации и/или после окончания дополнительно вводят функциональные добавки.1. A method of preparing a concrete mixture, including the preliminary activation of the hydraulic ash of TPP with part of the mixing water, followed by mixing the resulting ash suspension with cement, aggregates and the remaining part of mixing water, characterized in that the hydraulic ash of the TPP is activated at a water-solid ratio of 0.3 to 0 , 5, first at a particle collision speed of 20.0-30 m / s and for 1.0-2.0 s, and then for 2.0-3.0 s at a particle collision speed of 35.0-45, 0 m / s, and mixing the resulting ash suspension with cement, aggregates and the remainder of the mixing water is carried out in the following ratio of components, parts by weight: 2. The method according to claim 1, characterized in that the ashes of hydraulic removal of thermal power plants of the following composition are used, wt.%: 3. The method according to claim 1, characterized in that functional additives are additionally introduced into the ash suspension upon activation and / or after completion.
