В данной рецептуре хлористый кальций гидроокись кали КОН вл ютс интенсификаторами схватывани и Твердени , а ввод сульфосалициловрй кислоты (CCK)-H(D--SC H(OH)cbOH позвол ет понизить водоцементное отцошение замечет, пластификации цёмент;Ного раствора, не .привод к замедлению процессов гидратации.In this formulation, calcium chloride, potassium hydroxide KOH, is an intensifier of setting and hardening, and the input of sulfosalicylic acid (CCK) -H (D - SC H (OH) cbOH) reduces the cement-cement concentration, plasticizing the target; No solution, no drive to slow down the hydration processes.
В табл. 1 представлены свойства тампонажного раствора из лежалых Цементов Спасского и Чернореченского зводов .In tab. Figure 1 shows the properties of the cement slurry from old Cements of the Spassky and Chernorechensky zvodov.
в табл. 2 представлены сравнительные данные по тампонажНым растворам известного и предлагаемого изобретений .in tab. 2 presents comparative data on the cementing solutions of the known and proposed inventions.
Пример. Дл получени тампонажных растворов берут хранившиес б мес. пробы цементов двух заводов - Спасского и Чернореченского..Добавки CaCI-j, КОН и сек и воду Ьмешивают в течение 3 мин. в соотношени х, приведенных в прилагаемой таблице. Растворы твердеют при температуре и в холодильной камере ,при 5+ 0,3с. Example. To obtain cement slurries, stored b months are taken. samples of cement of two plants - Spassky and Chernorechensky .. Additives CaCI-j, KOH and s and water b are mixed for 3 minutes. in the ratios given in the attached table. The solutions harden at temperature and in the refrigerating chamber, at 5 + 0.3 s.
В предлагаемом тампонажном растворе , как видно из таблиц 1 и 2,. достигаетс значительное увеличение прочностных свойств камн , полученного из лежалого цемента, снижаетс до нул водоотделение, сроки схватывани позвол ют ос уществл ть процесс цементировани в течение технологически необходимого времен,и. При В/Ц ниже 0,35 растекаемость ниже допустимой,а с увеличением В/Ц более О,5 прочность меньше требуемой по стандарту.Сроки ожидани затвердевани цементного расвора (ОЗЦ) могут быть значительно сокращены за счет более быстрого набора камнем прочностных свойств. В св зи со сниженными водоцементными отношени ми камень из предлагаемого тампонажного раствора обладает повышенной сопротивл емостью знакопеременным температурным воздействи м.In the proposed cement slurry, as can be seen from tables 1 and 2 ,. a significant increase in the strength properties of the stone obtained from the stale cement is achieved, the water separation decreases to zero, the setting time allows the cementing process to take place during the technologically necessary times, and. When W / C is below 0.35, flowability is lower than acceptable, and with increasing W / C more than 5, strength is lower than required by the standard. Waiting time for hardening of the cement spread (HRC) can be significantly reduced due to a faster set of stone strength properties. In connection with reduced water-cement ratios, the stone from the proposed cement slurry has an increased resistance to alternating temperature effects.
Из табл. 2 видно,.что тампонажный раствор согласно предлагаемому изобретению дает стабильный прирост прочности камн во времени и обладает большей прочностью, особенно к 90 или 180 сут.From tab. 2 it can be seen that the cement slurry according to the invention gives a stable increase in stone strength over time and has greater strength, especially by 90 or 180 days.
Предлагаемый тампонажный раствор успешно прошел промышленное испытание в Якутской АССР.The proposed cement slurry successfully passed an industrial test in the Yakut ASSR.
