Изобретение относитс к обработке заполнител цементно-бетонных изделий и может быть использовано в промышленности строительных материалов.The invention relates to the processing of cement-concrete aggregates and can be used in the building materials industry.
Известен способ обработки кварцевого песка дл цементно-бетонных изделий путе -i последовательной выдержки его в 10%-ном растворе сол ной кислоты и промывке дистиллированной водой с целью удалени присадки железа на поверхности зерен l A known method of treating quartz sand for cement-concrete products is through i sequentially holding it in a 10% hydrochloric acid solution and washing it with distilled water to remove iron additive on the surface of the grains.
Целью изобретени вл етс повышение сцеплени заполнител с цементным камнем при использовании в качестве него фосфорнсмилакового щебн .The aim of the invention is to increase the adhesion of the aggregate to the cement stone when using phosphorus crushed stone as it.
Цель достигаетс тем, что в способе обработки заполнител дл ементно-бетонных изделий путем выдерживани заполнител в водном растворе сол ной кислоты используемый в качестве заполнител фосфорношлаковый щебень выдерживают в водном растворе сол ной кислоты с концентрацией ОД1 ,0 г моль/л в течение 0,017-3 ч.The goal is achieved in the method of aggregate processing for cement-concrete products by keeping the aggregate in an aqueous solution of hydrochloric acid, the phosphor-slag crushed stone used as an aggregate is kept in an aqueous solution of hydrochloric acid with a concentration of OD1, 0 g mol / l for 0.017-3 h
В качестве исходных материалов дл выполнени экспериментов использованы фосфорношлаковый щебень Джамбулского фосфорного завода фракции 5-10 и 10-20 мм, техническа сол на кислота и ее водные растворы; портландцемант Чимкентского цементного завода активностью 390 кгс/ см и песок полевошпатовый Николаевского карьера с модулем крупности 2,2. 5 Бетонные образцы изготовл ют из смеси с осадкой конуса Абрамса 2-Зсм при проектной марке бетона 200. Заполнитель бетона - фосфорношлаковый щебень обрабатывают в водных раство10 pax сол ной кислоты концентрации от 0,1 до 1,0 г моль/л в течение 1,3, 12, 24 ч.Phosphorus and slag crushed stone of the Dzhambul Phosphorus Plant, fractions 5-10 and 10-20 mm, technical hydrochloric acid and its aqueous solutions were used as starting materials for the experiments; Portland cement of Chimkent cement plant with an activity of 390 kgf / cm and feldspar sand of the Nikolaev open pit with a modulus of 2.2. 5 Concrete samples are made from a mixture with a 2-Zsm Abrams cone sludge with a design grade of concrete 200. The concrete aggregate — phosphor-slag crushed stone is treated in aqueous solutions of hydrochloric acid with a concentration of from 0.1 to 1.0 g mol / l for 1, 3, 12, 24 hours
Расход,материалов дл проектируемой марки бетона 200 на 1 м бетона прин т следующим:The consumption of materials for the designed concrete grade 200 per 1 m of concrete is as follows:
Цемент310 кгCement 310 kg
ФосфорношлаковыйPhosphoroslag
щебень1140 кгcrushed stone 1140 kg
Песок700 кгSand 700 kg
20 Вода149 л20 Water149 l
Как видно из данных таблицы, обработка фосфорношлакового шебн водными растворами сол ной кислоты существенно повышает его качество и прочность 25 бетонов, приготовленных на этом щебне . При этом прочность бетона на обработанном щебне повышаетс в 1,0 1 ,3 раза, что позвол ет снизить расход цемента дл бетона марки 300 30 на 20%.As can be seen from the data in the table, the processing of phosphorus slag sheath with aqueous solutions of hydrochloric acid significantly improves its quality and durability of 25 concretes prepared on this rubble. At the same time, the strength of concrete on the treated crushed stone increases by 1.0 1, 3 times, which makes it possible to reduce the consumption of cement for concrete 300 30 by 20%.
