High-strength non-shrink grout material winter maintenance

High-strength non-shrinkage grouting material winter construction, no special requirements on strength growth, 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 ℃. In minus temperature condition maintenance without watering. 2. After ripping of high-strength non-shrink grout material cement grouting material is greater than the difference between the surface temperature and environmental temperature 20 ℃, the heat preservation material covered protection should be adopted. 3. High-strength non-shrink grout material such as environmental temperature is lower than cement grouting material minimum temperature or need to speed up the construction strength increasing, high-strength non-shrinkage grouting material can use artificial heating curing way; Curing measures should comply with the current national standard 'architectural engineering winter construction regulations' the relevant provisions of the JGJ104.
