Fujian high-strength non-shrinkage ceramic tile seam filling agent in winter construction and maintenance

For fujian high-strength non-shrinkage tile gap filling agent in energy-saving, section, material, engineering economy, labor protection and environmental protection and so on is of great significance, its application in civil engineering are rapidly, therefore, to strengthen high-strength non-shrinkage caulking agent curing ceramic tile, make clear curing condition and the method of high strength without shrinkage performance effects and mechanism of ceramic tile gap filling agent is particularly important. Fujian high-strength non-shrinkage ceramic tile seam filling agent in winter construction and maintenance: a, winter construction: daily average temperature below 5 ℃ should be in accordance with the size of winter construction and meet the following requirements. 1, measures should be taken to preheat before grouting foundation surface, keep the temperature above 10 ℃, and clear water. 2, should use no more than 65 ℃ warm water mixing and cement grouting material, the slurry into the mold temperature above 10 ℃. 3, before the cold, compressive strength of cement grouting material shall not be less than 5 mpa. Winter construction maintenance: 1, the winter construction, the project has 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 cement grouting material is greater than the difference between the surface temperature and environmental temperature 20 ℃, heat preservation material covered protection should be adopted. 3, such as environmental temperature is lower than the minimum of cement-based grouting materials construction temperature or need to speed up the growth intensity, 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.
