Изобретение относитс к области производства бетоиов.This invention relates to the production of beioi.
Известна бетонна смесь, включающа цемент и шлаковый заполнитель.A known concrete mixture comprising cement and slag aggregate.
Цель изобретени - повысить прочность бетона и его долговечность.The purpose of the invention is to increase the strength of concrete and its durability.
Это достигаетс тем, что бетонна смесь в качестве заполнител содержит смесь грубомолотого стекловидного (гранулированного) и дробленого закристаллизованного доменного шлака в соотношении 1:4-1:1. Стекловидный (гранулированный) доменный шлак включает зерна до 2,5 мм н частицы менее 0,14мм в количестве 20-30%, а закристаллизованный доменный шлак имеет следующий фракционный состав, вес. %:This is achieved by the fact that the concrete mixture as a filler contains a mixture of coarsely ground glassy (granulated) and crushed, crystallized blast furnace slag in a ratio of 1: 4-1: 1. Vitreous (granulated) blast furnace slag includes grains up to 2.5 mm n particles less than 0.14 mm in the amount of 20-30%, and the crystallized blast furnace slag has the following fractional composition, weight. %:
5-10 мм8-205-10 mm8-20
1,25-5 мм46-581.25-5 mm46-58
0,14-1,25 мм22-340.14-1.25 mm22-34
Менее 0,14 мм6-10Less than 0.14 mm6-10
Бетонную смесь изготавливают путем совместного перемешивани цемента с заполнителем и водой.The concrete mix is made by mixing cement together with aggregate and water.
Физнко-механическне свойства бетона характеризуютс следующими показател ми.The mechanical properties of concrete are characterized by the following indicators.
400-900 КГС/СМ2 не менее 500 циклов более 20 атм 0,27-0,38 мм/м.400-900 KGS / SM2 not less than 500 cycles more than 20 atm 0.27-0.38 mm / m.
