High-strength non-shrink grout material how to maintain?

1, high-strength non-shrink grout material how to maintain? (1) within 30 minutes after grouting, shall be immediately spraying curing agent or covering plastic film and maintenance, such as capping rock quilt or sprinkling water on grouting layer immediately after the final set, moisture curing. (2) the winter construction, curing measures should also conform to the acceptance specification for construction of reinforced concrete engineering GB50204 relevant regulations. (3) keep under different conditions of temperature and curing time mold schedule. Through the above, shall be immediately spraying curing agent or covering plastic film and maintenance, such as capping rock quilt or immediately after the grouting layer final set sprinkler moisture curing. After the final set, curing, cover more suction wet cloth with water wet all day, strict curing period is 7 days, can actually curing with 4 days. And one more thing to say is that hold on the properties of grouting material, will test the performance of the grouting material block. The grouting material compressive specimens of curing method is what? Grouting material compressive specimens don't actually need to maintenance. But should always clean up after the experiment of dust. Pay attention to clean, and regularly check oil oil. 2, high-strength non-shrinkage grouting material curing period is how long? High-strength non-shrink grout material curing time shall not be less than 7 days. (1) when the grouting, the average daily uniform temperature should not be lower than 5 ℃, grouting after exposed part should be timely spraying curing agent or covering plastic film, affixed with wet straw bag stays wet. Using plastic mulch, cement grouting material of bare surface should be covered tightly, keep plastic film in the condensate. When water grouting material on the surface of the inconvenience, but spraying curing agent. (2) the grouting materials shall be maintained in the wet state, curing time shall not be less than 7 d. (3) when using fast setting type rapid hardening cement grouting material, curing measures should be executed according to the method of product requirements. (4) winter construction, the project has no special requirements on strength growth, [ 1] After the grouting exposed part should be timely covering plastic film and heat preservation materials. The initial curing temperature should not be lower than 5 ℃. Water in negative temperature curing condition. (5) after dismantle cement grouting material is greater than the difference between the surface temperature and environmental temperature 20 ℃, the heat preservation material covered maintenance should be adopted. 6 such as environmental temperature is lower than cement grouting material minimum temperature or need to speed up the construction strength growth, can use artificial heating maintenance way. Knowledge of high-strength non-shrink grout material maintenance is said here, if you for maintenance, there are other questions, or other types of epoxy grout had maintenance problems, welcomed the consultation, we will give you a satisfactory answer.
