Игобре 1геиие касаетс строительных иатериапов и ыожет быть испопьзоваво в проыышпенноы, пракданскоий дородном строитедьстве дн изготовпени бетонных и жедезобетонных издеиий и конструкций . Известно испоц ьзование пиритных огарков в качестве сырь дп производства керамзита. Известно введение в бетонную сиесь на основе цемента добавки наарииер хлористого кальци повышающей ее морозостойкость и прочность. Целью изобретени вл етс улучшение удобоукладываемости бетонной смеси и повышение прочности и морозостойкости бетона. Это достигаетс тем, что в качестве добавки в цементнобетонную примен ют пиритные огарки в количестве 30-60/S от веса цемента, Пиритные огарки вл ютс побочным.: продуктом при получении серной кислоты и представл ют собой тонкий порошок темно-красного цвета. При введении пиритных огарков в бетонную месь вход щие в их состав окислы взаимодействуют с известью, выдел ющейс в процессе гидролиза цемента. Образующиес дополнительно гидратные соединени уплотн ют и упрочн ют структуру материала, Пиритные огарки ввод т в смесительную установку совместно с заполнител ми . Прочность образцов песчаных бетонов с указанной добавкой на 28 сутки твердени составл ет 38,5-55,6 кг/см морозостойкость этих же образцов после 100 циклов соответственноI 46,6-60,4 КГ/СМ , a водонасыщение 7,32-7,95.

Кроме того, пиригаые огар ки придаю бетонным смес м устойчивую во времени окраску, поэтому такие сыеси можно использовать при товлении декора1ивных бегонвых и железобеюнных изделий ФОРМЛ1А ИЗОБРЕТЕНИЯ Применение пиригных огарков в качестве добавки в цеменгнобегоннуш смесь дл улучшени ее удобоукиадываемости и повышени прочности и морозостойкости бетона.IGOBRE is concerned with building materials and can be used for productive, prakdan pre-emptive construction and construction of concrete and reinforced concrete products and structures. Known is the use of pyrite Ogarkov as a raw material dp production of expanded clay. It is known to introduce calcium carbonate additives in a concrete cement-based cement that increases its frost resistance and strength. The aim of the invention is to improve the workability of the concrete mix and increase the strength and frost resistance of concrete. This is achieved by using as an additive in cement concrete pyrite cinder in an amount of 30-60 / S by weight of cement. Pyrite cinder is a by-product: a product that produces sulfuric acid and is a fine powder of dark red color. When pyrite cinders are introduced into the concrete mixture, the oxides in their composition interact with the lime released during the hydrolysis of the cement. The additionally formed hydrate compounds condense and strengthen the structure of the material. Pyrite cinders are introduced into the mixing plant together with aggregates. The strength of sand concrete samples with this addition on the 28th day of hardening is 38.5-55.6 kg / cm frost resistance of the same samples after 100 cycles, respectively, 46.6-60.4 KG / CM, and water saturation 7.32-7, 95 Cement bdoki containing the proposed additive, characterized by its high durable Hugh and iorozustoykostiyu, whose behony without additives They otchichayue good workmanship. In addition, piriga cigars give concrete mixtures a color-stable color, so these combinations can be used in crafting decorative begonones and concrete products FORML1A of the INVENTION. Using pyrginic butts as an additive to the cement mix to improve its ease of movement and to improve its efficiency and to improve its efficiency.
