Description
(54) ВЯЖУЩЕЕ(54) BINDING
Изобретение относитс к производству строительных материалов, в частности к составам в жущих на основе гипса.The invention relates to the production of building materials, in particular, to gypsum-based agitating compositions.
Известно в жущее, включающее, %: термообработанный алунит 60-70 и . : гипс 30-40 1 .It is known in the gutter, including,%: heat-treated alunite 60-70 and. : gypsum 30-40 1.
Наиболее близким по технической сущности и.достигаемому эффекту к предлагаемому вл етс в жущее, включающее,%: обожженный алюмосиликатный компонент - твердый остаток отходов содового производства 19 ,5-53,7 и лолуводный гипс 46,380 ,5% 2.The closest to the technical essence and the achievable effect to the proposed is a stinging, including,%: calcined aluminosilicate component - solid residue of soda ash production 19, 5-53.7 and gypsum 46,380, 5% 2.
Недостатками известных в жущих вл ютс низкие скорость .твердени и прочность.The disadvantages of the known people are the low speed of hardening and strength.
Цель изобретени - ускорение твердени и повышение прочности.The purpose of the invention is to accelerate hardening and increase strength.
Поставленна цель достигаетс тем, что в жущее, включающее термообработанный алюмосиликатный компонент и компонент, содержащий сульфат кальци , содержит в качестве термообработанного алюмосиликатного компонента алунит, а в качестве компонента , содержащего сульфат кальци , , ангидрит при следующем соотношении компонентов, вес.%:The goal is achieved by the fact that, as a heat exchanger, including a heat-treated aluminosilicate component and a component containing calcium sulfate, contains alunite as a heat-treated aluminosilicate component, and as a component containing calcium sulfate, anhydrite in the following ratio, wt.%:

Пример. Смесь исходных компонентов подвергают обжигу при в течение 30 мин (образуетс ангид20 рид). Обожженную смесь размалывают до остатка на сите 008 не бблее 10%.Example. The mixture of the precursor components is calcined for 30 minutes (anhydride 20 is formed). The calcined mixture is ground to a residue on a 008 sieve of no more than 10%.
В таблице приведены в сравнении с известными составы в жущего ( примеры 1гб) и их свойства. Примечание: В примерах полуводный The table below shows in comparison with the known compositions in the idle (examples 1gb) and their properties. Note: In the examples, semi-aquatic
