Изобретение относитс к технологии строительных материалов, а именно к способам изготовлени изделий и конструкций из поризованных легких бетопов.The invention relates to the technology of building materials, in particular to methods for the manufacture of products and structures made of porous light concrete.
Известен способ приготовлени поризованной легкобетонной смеси, состо щий из следующих операций:A known method of preparing a porous light concrete mixture, consisting of the following operations:
в смеситель заливают нагретую до 60-70°С воду;in the mixer pour heated to 60-70 ° C;
ввод т минеральное в жущее, заполнитель и смесь перемещивают в течение 2-3 мин;the mineral is injected into the trash, the aggregate and the mixture is moved within 2-3 minutes;
ввод т пенообразователь, смесь перемещивают в течение 1 мин;a foaming agent is introduced, the mixture is moved for 1 minute;
затем добавл ют осгавшуюс часть воды, после чего смесь снова тщательно перемешивают в течение 1 мин. Приготовление смеси занимает не менее 5 мин.then a part of water was added, after which the mixture was thoroughly mixed again for 1 minute. Preparation of the mixture takes at least 5 minutes.
При таком способе приготовлени поризованной легкобетонной смеси приходитс вводить значительное количество воды затворени . Повыщение содержани воды затворени в поризованных легких бетонах ведет к снижению их прочностных показателей и увеличению объемной массы. Изготовленные из них издели имеют относительно высокую технологическую влажность.With this method of making porous light concrete, a significant amount of mixing water must be injected. Increasing the content of mixing water in porous lightweight concretes leads to a decrease in their strength properties and an increase in the volume mass. Products made from them have a relatively high technological humidity.
Цель предлагаемого изобретени - уменьщение водопотребности смеси и повышение ее однородности. Достигаетс это тем, что в жущее с водой и частью заполнител , напримерThe purpose of the present invention is to reduce the water demand of the mixture and increase its uniformity. This is achieved by staying with water and part of the filler, for example
с 50-60% потребного на замес его количества , перемешивают в течение 1 -1,5 мин, затем в смесь ввод т нри перемешивании техническую пену, после чего ввод т оставшуюс from 50-60% of the quantity required per batch, stirred for 1-1.5 minutes, then technical foam is added to the mixture, and the remaining
часть заполпител и вновь перемешивают в течение 0,5-1 мин.part of the filling and again mixed for 0.5-1 minutes.
Продолжительность процесса приготовлени керамзитопенобетонной смеси по данному способу составл ет 3,5-4 мин. При изготовлении поризованной легкобетонной смеси по новой технологии на 10-15% снижаетс ее водопотребность, что ведет к повышению прочности бетона, улучшаютс показатели изменчивости и коэффициенты однородности поThe duration of the process for preparing the expanded clay foam concrete mixture according to this method is 3.5-4 minutes. In the manufacture of porous light concrete mix according to the new technology, its water demand is reduced by 10-15%, which leads to an increase in the strength of concrete, improved variability and uniformity coefficients for
прочности и объемной массе бетона.strength and bulk weight of concrete.
Предмет изобретени Subject invention
Способ приготовлени порнзованной легкобетонной смеси путем смешивани минерального в жущего, пористого заполнител , воды и технической пены, отличающийс тем, что, с целью уменьшени водопотребности смеси и повышени ее однородности, в жущее с водой и частью заполнител , например с 50-60% потребного на замес его количества, перемешивают в течение 1-1,5 мин, затем в смесь ввод т при перемешивании техническую пену, затем оставшуюс часть заполнител и вновь перемешивают в течение 0,5-1 мин.A method for preparing a lightweight concrete mixture by mixing a mineral binder, a porous aggregate, water and technical foam, characterized in that, in order to reduce the water requirement of the mixture and increase its homogeneity, milling with water and part of the aggregate, for example from 50-60% mixing the quantities, stirring for 1-1.5 minutes, then technical foam is introduced into the mixture with stirring, then the remaining part of the aggregate and again stirred for 0.5-1 minutes.
