Description
Изобретение относитсй к цементной ПрО мышленности и может примен тьс в производстве белитовых цементов, обладающих повышенной кислото- и сульфатостойкостью и Явл ющихс эффективными в жущими веществами дл возведени гидротехнических сооружений .The invention relates to cement Cement Mill and can be used in the production of belite cements with high acid and sulphate resistance and being effective in tangible substances for the construction of hydraulic structures.
Известно, что гидроокись кальци ранее примен лась дл синтеза двухкальциевого силиката в смеси с разными кремнеземистыми материалами (аморфна кремнекислота, очищенный песок, кристобалит, природный песок). Однако реакционна способность этих смесей при обжиге очень низка. Так, например, сырьева смесь, рассчитанна на получение двухСырьевые смеси приготавливались в следующих соотношени х, вес. %:It is known that calcium hydroxide was previously used for the synthesis of dicalcium silicate in a mixture with different silica materials (amorphous silicic acid, purified sand, cristobalite, natural sand). However, the reactivity of these mixtures during firing is very low. So, for example, the raw material mixture, designed to produce two-Synthetic mixtures were prepared in the following ratios, wt. %:
к льцйевого силиката, после обжига даже при 1400°С в течение 3-х час дает клинкер с содерЖаиием 3,79% иепрореагировавшей окисИ кальци .after firing, even at 1400 ° С for 3 hours, it gives clinker with a content of 3.79% and unreacted calcium oxide.
Цель изобретени -повыщение реакционной способности смеси.The purpose of the invention is to increase the reactivity of the mixture.
Достигаетс это тем, что смесь дополнительно содержит гранулированный электротермофосфорный шлак при следуюш,ем соотношении компонентов, вес. %:This is achieved by the fact that the mixture additionally contains granulated electrothermophosphoric slag at the next component ratio, wt. %:
Известь-пушонка15-40Pushon15-40 lime
Электротермофосфатный шлак 60-85 Химический состав сырьевых компонентов в вес. % следующий:Electrothermophosphate slag 60-85 The chemical composition of raw materials in weight. % next:
Установлено, что испытанные сырьевые смеси при обжиге показывают весьма высокую скорость реакции образовани двухкальциевого силиката. Так, например, клинкер, содержащий даже до 90% CaS получаетс за 30 минIt has been found that the tested raw materials during calcination show a very high reaction rate for the formation of dicalcium silicate. For example, clinker containing even up to 90% CaS is obtained in 30 minutes
при 1000°. В полученных клинкерах двухкальциевый силикат находитс в виде р-модификации . Предлагаема сырьева смесь не нуждаетс во введении специального стабилизатора дл р-CaS. Полученный клинкер весьма устойчив против силикатного распада и не показывает никаких признаков модификационпого превращени после годичного хранени на воздухе.at 1000 °. In the resulting clinkers, dicalcium silicate is in the form of p-modification. The proposed feed mixture does not require the introduction of a special stabilizer for p-CaS. The resulting clinker is very resistant to silicate decomposition and shows no signs of modification after one year of storage in air.
