BAIJIAN - Third party testing organization
The sleeve grouting material should be used in conjunction with the grouting sleeve、 and the inspection of the grouting material is divided into factory inspection and type inspection The factory inspection items include: initial fluidity; 30min flowability; 1d、 3d、 28d compressive strength; 3h vertical expansion rate; The difference in vertical expansion rate between 24 hours and 3 hours、 as well as the bleeding rate Except for all the items in the factory inspection、 type inspection should be carried out in one of the following situations: (1) type identification of new products; (2) After formal production、 if there are significant changes in materials and processes that may affect product quality; (3) When production is resumed after more than half a year of suspension; (4) When the type inspection exceeds 2 years When delivering、 the manufacturer should provide a product certificate、 user manual、 and product quality inspection report、 which includes factory inspection and type inspection The sampling rule for factory inspection is that 50 tons of products with the same formula and batch number of raw materials produced within 15 days should be considered as an inspection batch、 and less than 50 tons should also be considered as an inspection batch During inspection、 samples should be taken from multiple parts in equal quantities、 with a total sample size of no less than 30kg、 to make the product sampling representative. Only when all indicators of the factory inspection and type inspection of the grouting material meet the requirements of JG/T 408-2013 "Sleeve grouting material for steel bar connection" can it be judged as qualified product. Otherwise、 if one indicator does not meet the requirements、 it will be judged as unqualified product. Grouting materials that fail the quality inspection shall not be used in construction projects
