Изобретение относитс  к составам дл  укреплени  глинистого грунта и может быть использовано в дорожном, аэродромно.м и других строительствах.The invention relates to compositions for strengthening clay soil and can be used in road, airfield m and other constructions.

Известные составы на основе фосфорсодержащих веществ не обеспечивают получени  необходимы.х физико-механических показателей укрепленного грунта.Known compounds based on phosphorus-containing substances do not provide the necessary physical and mechanical properties of the fortified soil.

Цель предлагаемого изобретени  - улучщить физико-механические показатели укрепленного грунта.The purpose of the present invention is to improve the physico-mechanical properties of the fortified soil.

Предлагаемый состав содержит компоненты в следующем соотнощении, вес. %:The proposed composition contains components in the following ratios, weight. %:

Ортофосфорную кислоту1-25Phosphoric acid1-25

Фосфогиис20-30Phosphogyes20-30

ВодуДо 100Water up to 100

и кроме того, кремнефтористоводородную кислотуI-25and in addition, fluorosilicic acid I-25

Новый состав дл  укреплени  глинистого грунта готов т смешением фосфогипса с водны .м раствором ортофосфорной кислоты в стандартных мещалках. Целесообразно готовить такой состав на суперфосфатном заводе. В препарационном отделении, где производитс  обработка апатита серной кислотой,следует отдел ть от шлама (фосфогипса) на всю Ортофосфорную кислоту, а оставл ть ее частично в П1ламе. Такой шлам разбавл ют во2A new composition for strengthening the clay soil is prepared by mixing phosphogypsum with aqueous solution of orthophosphoric acid in standard meshes. It is advisable to prepare such a composition in a superphosphate plant. In the preparative section, where apatite is treated with sulfuric acid, it should be separated from the sludge (phosphogypsum) for all orthophosphoric acid, and leave it partially in P1lam. Such sludge is diluted with bo2.

дои или водным раствором кремнефтористоводородной кислоты до следующего состава, содержащего компоненты в следующем соотношении , вес. %:doi or aqueous solution of hydrofluoric acid to the following composition, containing the components in the following ratio, weight. %:

Ортофосфорную кислоту1-25Phosphoric acid1-25

Кремнефтористоводородную кислоту1-25Fluorosilicic acid1-25

Фосфогипс20-30Phosphogypsum 20-30

ВодуДо 100Water up to 100

Если при приготовлении состава раствор кремнефтористоводородной кислоты не добавл етс  к фосфогипсу, то в конечно суспензии будет присутствовать 1-2 вес. % этой кислоты , так как в препарационной ортофосфорной кислоте, пе прошедшей операцию обесфтори-. вани , всегда имеютс  соединени  фтора.If, during the preparation of the composition, a solution of fluorosilicic acid is not added to phosphogypsum, then in the suspension of course 1-2 weight will be present. % of this acid, as in the preparative orthophosphoric acid, which has not undergone the operation of defluoro-. Vani, there are always fluorine compounds.

Образцы грунта, обработанные предлагаемым составол, лабораторном исследовании показали, что они имеют значительную прочность и водонепроницаемость.Soil samples, treated with the proposed composition, a laboratory study showed that they have significant strength and water resistance.

Предмет изобретени Subject invention

Состав дл  укреплени  глинистого грунта, включающий фосфорсодержащие вещества, отличающийс  тем, что, с целью улучщени  физико-механических показателей укрепленного груита, он содержит указанные компоненты в следующем соотпон ении, вес. %: 3:.
