How to correctly use grouting material make the effect best

A, add water, secondary perfusion for small space, can be directly add water mix into a paste, standard models of water added 13 ~ 15% for grouting material. Aggregate addition, concrete hollow perfusion for large space, can join 5 ~ 10 mm size stones, ratio of stones: ugm = 0. 3:1 ( Special circumstances according to changes in demand) Water added, 12% of the grouting material. Second, the irrigation methods, continuous grouting, not continuous and shorten the grouting time as much as possible. Grouting is strictly prohibited in the process of vibrating, if necessary, can use the bamboo pull the diversion. Perfusion is close-grained, slightly dry, rub the surface flat light. Three, before construction, should fill the space eluvial soil, loose clean, remove the oil, fill the space surface concrete need clean water prewetting 6 ~ 12 hours. Grouting material is widely used in high speed railway, metallurgy, petrochemical, electric power, coal, machinery, construction, light industry, Marine engineering, road and bridge, environmental protection, municipal equipment installation, in the field of structure strengthening in the major national construction projects, construction and maintenance.
