Description
Изобретение относитс к составам ({юсфатных п жур;их и может быть ис пользовано да1 получени бесцемент- него строительного раствора дл кладки силикатного кирпича в сейсмических районах, а также дл получени бесцементных строительных материалов .The invention relates to compositions ({yusfat plants); they can also be used to obtain a cementless mortar for laying silica brick in seismic areas, as well as for producing cementless building materials.
Целью изобретени вл етс повышение прочности в жущего.The aim of the invention is to increase the strength in the grip.
ФосЛогипсовую суспензию получают из низ сосортного фосфатного сырь , состава,%: экстракционна фосфорна кислота 5-20; сульфат кальци 30-50; недоразложенное сырье 5-20; серна , кислота 0,2-1,2; вода -остальное.The phosphorus suspension is obtained from the bottom of the pure phosphate raw material, composition,%: extraction phosphoric acid 5-20; calcium sulfate 30-50; underdeveloped raw materials 5-20; sulfuric acid 0.2-1.2; water is the rest.
Пример. В фосфогипсовую суспензию , полученную из низкосортного фосфатного сырь , при перемешивании внос т тонкомолотый серпентинит (уд. поверхность 4500 ). Из полученного теста дл определени механической прочности в жущего изготавливают кубики объемом 8 см.Example. Fine-ground serpentinite (sp. Surface 4500) is added to the phosphogypsum suspension obtained from low-grade phosphate raw materials with stirring. 8 cm cubes are made from the obtained dough to determine the mechanical strength of the glue.

лов провод т опыты при максимальных, минимальных и выход щих за предельные значени соотношени х компонентов в в жущем.The experiments were performed at maximum, minimum and beyond the limiting values of the ratios of the components in the idle.
5 Результаты опы.тов сведены в таблицу.5 The results of the experiments. Tabulated.
Как следует из данных таблицы, только в пределах предлагаемого соотношени компонентов возможно получение в жущего оптимальной прочности (примеры 1-3). При содержании фосфо- гипсовой суспензии в составе менее 55% (пример 4) получаемое в жущее не о.бладает требуемой прочностью, поскольку концентраци Т О оказываетс недостаточной.As follows from the data in the table, only within the limits of the proposed ratio of components is it possible to obtain an optimal optimum strength (examples 1-3). When the content of the phospho-gypsum slurry in the composition is less than 55% (Example 4), the resulting binder does not have the required strength, since the concentration of T O is insufficient.
При содержании фосфогипсовой суспензии более 70% (пример 5) получаемое фосфатное в жущее также не обладает требуемой прочностью, поскольку существенно возрастает содержание фосфогипса в составе в жущего , что и приводит к ухудшению свойств последнего.When the content of the phosphogypsum suspension is more than 70% (example 5), the resulting phosphate sticking agent also does not have the required strength, since the content of phosphogypsum in the slurry composition significantly increases, which leads to deterioration of the properties of the latter.
