FIELD: mining. ^ SUBSTANCE: reagent for grouting mortar on mineral binding contains aluminium hydroxychloride, additionally contains amorphous aluminium oxide or aluminium hydroxide or their mixture at following ratio of components, wt part: aluminium hydroxychloride - 40-60, and amorphous aluminium oxide or aluminium hydroxide or their mixture - 40-60. The grouting solution contains cement, water and the said reagent at amount of from 0.5 to 3.0% from cement weight. Additionally the said grouting solution can contain in wt % from cement: filtrate agent - 0-0.8, plasticiser - 0-0.5, and de-foaming agent - 0-0.5. ^ EFFECT: creation of efficient reagent for grouting mortar not influencing its flow characteristics and facilitating forming of solid stone with increased resistance to deformation. ^ 3 cl, 9 ex, 1 tbl |
