Description

Временное сопротивление в кг/смг (раствор 1 :3)Temporary resistance in kg / cmg (solution 1: 3)

Из получедаых данных видно, что шлаковый бескликакерный цемент из кислых доменнЫХ -шлаков, активируемых сульфатом кальци  (двуводный гипс, полугидрат, ангидрит природный н искусственный) и тесиой смесью MgO с lOaO,  олучеиной обжигом долОМита при температуре 1100°, амеет более высокую механическую проч1ность, чеМ это наблюдаетс  при актиакровании сульфатом кальци  и портла1Н дцбмент«ым клинкером гашёной известью .From the obtained data it is clear that slag besklikakerny cement from acid domain slags activated by calcium sulfate (two-water gypsum, hemihydrate, natural n artificial anhydrite) and a mixture of MgO with lOaO, oleum calcining dolOMite at a temperature of 1100 ° C, and a higher mechanical strength, a mechanical structure, dolOmite at 1100 ° C, and a higher mechanical strength, a mechanical structure of dolOMite at 1100 ° C, a higher mechanical strength, and a higher mechanical strength. This is observed when calcium sulfate and Portal calcium sulfate are activated by slaked lime.

Наличие СаО способствует образованию гидр.осульфоалюмината кальцм , благ:о1п1рй т1но отражающегос  на активности шлаковых цеме тов , а MgO, гщратнзиру сь, создаёт щелочную среду, чем: ускор ет П1ро1цессы гидратации шлака.The presence of CaO contributes to the formation of hydrated calcium sulfoaluminate, benefits: an effect that reflects the activity of slag cement, and MgO, which creates an alkaline environment, than: it accelerates the slag hydration process.

Н€;{ аБНомерности изменени  в объёме за счёт гашени  СаО в обожжённом доломите н9 наблюдаетс , так как наличие сульфата кальци , как показали исследовани , предотвращают это  вление.H €; {ABNOMENERATION of change in volume due to the quenching of CaO in calcined dolomite N9 is observed, since the presence of calcium sulfate, as studies have shown, prevents this phenomenon.

, Свойство извести - гаситьс  в присутств-ии сульфата кальци  без заа етного увеличени  в объём1е - позвол ет получать шлаковый цемент из кислых шлаков, активируемых негашёной известью, что значительно удешевл ет стоимость цемента .The property of lime — quenched in the presence of calcium sulfate without a noticeable increase in volume — allows the production of slag cement from acidic slags activated by quicklime, which significantly reduces the cost of cement.

Количество вводимых добавок, и их соотношение зависит от химического cocTaiBa шлаков. ;The amount of added additives, and their ratio depends on the chemical cocTaiBa slags. ;

Предмет изо бретени Subject matter

Способ получени  бесклигжерного цемента из доменных кислых шлаков с пониженным содержанием окиси алюмини  и окиси кальци  путём введени  доба1вок, отлич а юЩИ1йо  тем, что в качестве до|бавок примен ют или смесь долом1ита, обожжённого при температуре около 1100°, с сульфатом кальци  или экстрих-гипсом, или негашёную известь в смеси с различными модифИкаци ми сульфата кальци .The method of obtaining beskligernogo cement from the blast acidic slag with a reduced content of aluminum oxide and calcium oxide by the introduction of additional, differently besides that as an additive used or a mixture of dolomite, calcined at a temperature of about 1100 °, with calcium sulphate or extre- gypsum, or burnt lime mixed with various calcium sulfate modifications.
