Abstract
Изобретение относитс к строительным материалам, а именно к составам комплексных добавок. Целью изобретени вл етс повышение удобоукладыва- емости во времени, а также повышени прочности, нормального сцеплени с силикатным кирпичом и морозостойкости . Комплексна добавка дл растворной или бетонной смеси включает, мас.%: сульфитно-дрожжева бражка 8,28-8,30, хромова кислота 0,44- 0,62, вода остальное. Осадка конуса дл раствора через 24 ч составила до 10 см, прочность на сжатие до 10,9 МНа, на изгиб до 4,7 МПа, нормальное сцепление с кирпичом через 300 сут 0,3-0,38 МПа, морозостойкость до 40 циклов. Подвижность бетон- р ной смеси составила 19 см, прочность бетона через 28 сут 35 МПа. 3 табл. S (ЛThis invention relates to building materials, namely, compound additive formulations. The aim of the invention is to improve workability over time, as well as to increase strength, normal adhesion with silica brick and cold resistance. The complex additive for a mortar or concrete mixture includes, in wt.%: A sulfite yeast mash 8.28-8.30, chromic acid 0.44-0.62, water the rest. The precipitate of the cone for the solution after 24 hours was up to 10 cm, compressive strength up to 10.9 MNa, bending up to 4.7 MPa, normal adhesion to the brick after 300 days 0.3-0.38 MPa, frost resistance up to 40 cycles. The mobility of the concrete mixture was 19 cm, the strength of concrete after 28 days was 35 MPa. 3 tab. S (l
Description
Изобретение относитс к строительным материалам, а именно к составам комплексных добавок дл строительных растворов дл кладки стен из силикатного кирпича, а также дл оетонных смесей в районах с повышенной сейсмичное ТЬЮоThe invention relates to building materials, in particular to compositions of complex additives for building mortars for masonry walls made of silicate bricks, as well as for ethanol mixtures in areas with high seismic values.
Целью изобретени вл етс повышение удобоукладываемости во времени, а также прочности нормального сцеплени с силикатным кирпичом и морозостойкости оThe aim of the invention is to improve workability over time, as well as the strength of normal adhesion to silica brick and cold resistance.
Способ приготовлени строительного раствора или бетонной смеси заключаетс в том, что в смеситель вначале заливают воду и 6т8.% от массы цемента комплексную добавку. Осуществл ют перемешивание в течение 10-15 с„ Затем добавл ют цемент и заполнитель,The method of preparing mortar or concrete mix is that first the water and 6t8.% Of the cement weight are mixed into the mixer. Stirring is carried out for 10-15 seconds. "Then cement and aggregate are added,
вновь осуществл ют перемешивание в течение 2-3 мин до получени однородной смесиоstir again for 2-3 minutes until a homogeneous mixture is obtained.
В качестве контрольного состава бетонной смеси используют состав, содержащий, кг/1м3:As a control composition of the concrete mix, use is made of a composition containing, kg / 1m3:
