Quanzhou high-strength non-shrinkage 4 kinds of strength grade ceramic tile gap filling agent is introduced

Quanzhou ceramic tile seam filling agent is a kind of special form of expression of concrete, is a special kind of concrete, it has the performance of the normal concrete does not have, such as gravity, no shrinkage, micro expansion, construction without any vibration, can be widely construction places. Cement concrete is a cement ( Or proper active admixture cement) As the cementing material, with water and coarse and fine aggregate material made with mixed in certain proportion, mixture again after casting forming hardening after artificial stone. No hardening of new mixing of concrete, usually become concrete mixture ( Or fresh concrete) 。 The hardening says hardened concrete have a certain strength of concrete. Usually refers to the cement concrete, in the road engineering, asphalt concrete is a kind of common concrete. Ceramic tile seam filling agent label and strength grade: intensity of ceramic tile seam filling agent from the label to the change of strength grade, is mainly due to the adopted different strength inspection methods, namely from GB method to ISO method. This is standard for the ceramic tile seam filling agent in China to the international standards and consistent with the to make major changes. Ceramic tile seam filling agent label and strength grade: the main difference in two ways. One is used for standard specimen with different size, label and strength grade cube specimens used side length is 200 mm and 150 mm respectively; Second is the difference between the accessor methods, strength grade have clear statistical concept, namely the strength standard values is the average of the intensity of population distribution minus 1. 645 times the standard deviation, the label is no clear concept of mathematical statistics, according to the calculated its insurance rate is about 85%. Quanzhou high-strength non-shrinkage ceramic tile seam filling agent has the following four kinds of strength grade: 1, CGM - 1 general rugged. grouting thickness of 30 mm & lt; δ< 150 mm equipment foundation secondary grouting, anchor bolt anchorage, planted, buried steel beam, slab, column, foundation and building floor reinforcement reinforcement. 2,CGM - 2 pisolite rugged. Contain 5 ~ 10 mm of large aggregate, suitable for grouting layer thickness of the delta p 150 mm, and the length of the grouting L< 1000 mm equipment foundation secondary grouting. The structure of the beam, slab, column, foundation and ground reinforcement reinforcement ( Repair the thickness of 60 mm or higher) 。 3、CGM- 3 superfine rugged. Super fine aggregate, is suitable for grouting layer thickness 5 mm & lt; δ< 30 mm equipment foundation and steel structure column foot secondary grouting. The gap between Angle steel and concrete grouting strengthening concrete beams. 4、CGM- Strengthen the type 4 super early strength. 2 hours intensity 15 mpa, pillow is suitable for railway track fast repair, such as cement concrete pavement, airport runway, such as rapid repair, water plugging rapid repair.
