Claims (6)

1. Способ получения пластифицированных портландцементов, включающий совместный помол исходного цемента с суперпластификатором С-3-натриевой солью продукта конденсации нафталинсульфокислоты с формальдегидом, отличающийся тем, что суперпластификатор С-3 берут в количестве 2 - 5% от массы цемента, а помол осуществляют в виброцентробежной мельнице при ускорении 10 - 20 g до остатка на сите 0,08 не более 0,5%, причем суперпластифицикатор предварительно подвергают активации путем помола в виброцентробежной мельнице при ускорении 10 - 20 g.1. A method of producing plasticized Portland cement, including co-grinding the source cement with a superplasticizer C-3-sodium salt of the condensation product of naphthalene sulfonic acid with formaldehyde, characterized in that the superplasticizer C-3 is taken in an amount of 2-5% by weight of the cement, and the grinding is carried out in a vibrocentrifugal mill with acceleration of 10 - 20 g to a sieve residue of 0.08 no more than 0.5%, and the superplasticizer is preliminarily activated by grinding in a vibrocentrifugal mill with acceleration of 10 - 20 g. 2.

The method according to claim 1, characterized in that the initial cement containing granulated slag in an amount of 5-40% is taken for grinding. 3. Способ по пп.1 и 2, отличающийся тем, что для помола берут исходный цемент, содержащий не более 5% гранулированного шлака. 3. The method according to PP.1 and 2, characterized in that for grinding take the original cement containing not more than 5% of granulated slag. 4. Способ по пп.1 и 2, отличающийся тем, что для помола берут исходный цемент с минеральными добавками, содержащий 5 - 20% гранулированного шлака. 4. The method according to PP.1 and 2, characterized in that for grinding take the original cement with mineral additives containing 5 to 20% of granulated slag. 5. Способ по пп.1 и 2, отличающийся тем, что для помола берут исходный цемент, содержащий 20 - 40% гранулированного шлака. 5. The method according to claims 1 and 2, characterized in that the initial cement containing 20-40% of granulated slag is taken for grinding. 6. Способ по пп.1 - 5, отличающийся тем, что при помоле дополнительно вводят противоморозные добавки в количестве не более 5% от массы цемента. 6. The method according to claims 1 to 5, characterized in that when grinding, antifrosty additives are additionally introduced in an amount of not more than 5% by weight of cement.
