Description

Предметом изобретени   вл ете ci:oco6 изготоплсмнп иемеитпых суспензий нз известково-иуццолановых цементов ип изготовлении из 1ИХ строительных растворов и бетонов, преследующий цель повышении прочности известково-пуццолановых растворов н бетонов н повышени  их морозостойкости и воздухостоГгкости.The subject of the invention is ci: oco6 isotoplssnm imeitepnyh suspensions nz lime-iutstsolanovyh cements made from 1IH mortars and concretes, aiming at increasing the strength of lime-pozzolan solutions n concretes n increasing their frost resistance and air resistance.

Предлагаемый сиособ заключаетс  п изменении структуры цементной суспензии, что достигаетс  последовательным йведс; ем составных частей в его водную суспензию.The proposed method consists in changing the structure of the cement slurry, which is achieved by successive steps; component parts in its aqueous suspension.

Товарные отдельно размолотые сухие гидравлические добавки разбалтываютс  с водой в течение одной-дн х мимут в количестве, необходимом дл  затворени  бетона или раствора. В полученный вводитс  в небольшом (до ) количестве электролит, например, пзвесть, гпис, хлористый кальций и т. п. дл  коагул ции сусиензнн и перемешивание продолжаетс  в течение одной-полутора минут. После этого в шлам добавл етс  остальное, необходимое дл  цемента, количество извести и цементна  суснензи  перемешиваетс  до состо ни  однородности в течение 1,5-3 мин (до получени  однородного состава). Полученный состав используетс  дл  приготовлени  растворов и бетонов обычным пор дко .м.Commercial dry ground hydraulic additives, separately crushed with water for one-day mimut in an amount necessary for mixing the concrete or mortar. The resulting electrolyte is introduced in a small (up to) amount, for example, sandstone, gpis, calcium chloride, etc., to coagulate the siechens and mixing continues for one to one and a half minutes. Thereafter, the rest required for the cement is added to the slurry, the amount of lime and the cement slurry are mixed to a state of uniformity for 1.5-3 minutes (until a homogeneous composition is obtained). The resulting composition is used to prepare mortars and concretes in the usual order.

При .мокром размоле добавки необходимое дл  коагул ции суспензии количество извести (до 3%) вводитс  непосредственно в мельницу, а остальное вводитс  затем в готовую после помола суспензию.In the case of wet grinding, the amount of lime (up to 3%) required for coagulating the suspension is introduced directly into the mill, and the rest is then introduced into the suspension after grinding.

№ 81607- 2 Предмет изобретени No. 81607- 2 The subject invention

Способ приготовлени  цеме.нтных суспензий из известково-пуццолановых ,цементов при изготовлении из них строительных растворов и бетонов , отличающийс  тем, что отдельно размолотые сухие гидравлические добавки разбавл ют с водой в количестве, необходимом дл  затворени  бетона или раствора, в полученный шлам предварительно ввод т до 3% электролита, например, известь, гипс, хлористый кальций и тому подобное и полученный шлам перемешивают в течение 1 -1,5 мин, после чего добавл ют все количество извести, необходимое по составу демента, и цементную суспензию перемешивают до состо ни  однрродности ,.The method of preparing cement. Suspensions from lime-pozzolanic, cements in the manufacture of building mortars and concretes from them, characterized in that the separately ground dry hydraulic additives are diluted with water in an amount necessary for mixing the concrete or mortar, into the resulting slurry up to 3% of the electrolyte, for example, lime, gypsum, calcium chloride and the like and the resulting slurry is mixed for 1 -1.5 minutes, after which the whole amount of lime required for the composition of the dement and cement is added tnuyu suspension was stirred until the condition odnrrodnosti,.
