Description
разуетс при пересыщении системы известью/расширение цемента очень велико , что приводит к снижению- прочности и разрушению структуры твердеющего цемента (бетона). При низко прочности цемента в этом случае расход его дл изготовлени бетона должен быть увеличен, но это удерживает стоимость железобетонных изделий, причем цель повышени самонапр жени при этом не достигаетс .develops when the system is oversaturated with lime / cement expansion is very high, which leads to a decrease in strength and destruction of the structure of hardening cement (concrete). At low strength of the cement in this case, its consumption for the manufacture of concrete should be increased, but this will keep the cost of the concrete products, and the goal of increasing self-stress will not be achieved.
. Дл регулировани степени пересыщени Са(ОН)2 в твердеющем цементе расшир юща с добавка, согласно предлагаемому изобретению, содержит отходы полусухой гранул ции шлаков, которые образуютс при гранул ции дом нных шлаков и представл ют собой тончайший порошок из стекловидных частиц, Высока удельна поверхность и способJHocTb шлакового стекла взаимодействовать с Са(ОН)г и CaSO (известковое и сульфатное возбуждение) позвол ет выводить из системы часть Са(ОН) и Са5О и образовывать с ними соединени , повышающие прочность цемента (например , низкоосновные гидросиликаты кальци ) .. To control the degree of supersaturation, Ca (OH) 2 in hardening cement, the expanding additive according to the present invention contains waste semi-dry granulation of slags, which are formed during the granulation of blast furnace slags and are the finest vitreous powder, The JHocTb method of slag glass to interact with Ca (OH) g and CaSO (lime and sulphate excitation) allows you to remove part of Ca (OH) and Ca5O from the system and form compounds with them that increase the strength of the cement (for example , low-base calcium hydrosilicates).
В целом все эти реакции обеспечивают повышение прочности и самонапр жени -цемента.In general, all these reactions provide increased strength and self-adherence to cement.
Пример. На опытном заводе НИИЦемента были получены предлагаема и известна расшир ющие добавки и на их основе напр гающие цементы. Во всех случа х добавка вводилась в количестве 10% от веса цемента.Example. At the Pilot Plant of the Research Institute of Cement, the proposed additives were obtained and the expanding additives were obtained and, on their basis, tensile cements. In all cases, the additive was introduced in an amount of 10% by weight of cement.
В таблице приведены результаты испытаний цементов.The table shows the results of tests of cements.
