Abstract

1. Способ приготовления керамзитобетона, включающий активацию части воды затворения цементом и пластифицирующей добавкой, окончательное перемешивание активированной части воды затворения, крупного и мелкого заполнителя с оставшейся частью воды затворения, отличающийся тем, что производится активация 70% воды затворения цементом и пластифицирующей добавкой в течение 1 мин, затем осуществляют окончательное перемешивание оставшейся части воды затворения, дробленого керамзитового гравия, керамзитового и кварцевого песка с предварительно активированной водой затворения в течение 0,5 мин.2. Способ по п.1, отличающийся тем, что активация 70% воды затворения цементом и используемой добавкой производится в бетоносмесительной установке при 15 об/мин.3. Способ по п.1 или 2, отличающийся тем, что полученный керамзитобетон подвергают двухэтапной тепловой обработке при t=60°С (в летнее время 5 ч, в зимнее время 8 ч) и в камере вторичной тепловой обработки при t=40°С в течение 4 ч.1. A method of preparing expanded clay concrete, including the activation of part of the mixing water with cement and a plasticizing additive, the final mixing of the activated part of mixing water, coarse and fine aggregate with the remaining part of mixing water, characterized in that 70% of the mixing water is activated with cement and plasticizing additive for 1 min, then carry out the final mixing of the remaining part of the mixing water, crushed expanded clay gravel, expanded clay and quartz sand with preliminary about activated mixing water for 0.5 min. 2. The method according to claim 1, characterized in that the activation of 70% of the mixing water with cement and the additive used is carried out in a concrete mixing plant at 15 rpm. The method according to claim 1 or 2, characterized in that the claydite concrete obtained is subjected to a two-stage heat treatment at t = 60 ° C (in summer 5 hours, in winter 8 hours) and in a secondary heat treatment chamber at t = 40 ° C for 4 hours
