BAIJIAN - Third party testing organization
A significant feature of prefabricated concrete structures is the discontinuity of concrete and the truncation of steel bars at the joints caused by component segmentation and prefabrication. In order to achieve the integrity of the structure、 the grouting sleeve plays an irreplaceable role in achieving reliable connection of steel bars. Therefore、 quality inspection of the grouting sleeve used for steel bar connection is of great significance for ensuring the safety of prefabricated concrete structures. For the quality inspection of grouting sleeves、 we can start from two aspects: materials and finished products. Firstly、 we ensure that the materials used meet the relevant specifications、 and then control the quality of the finished products to see if their various performance indicators meet the actual needs. For the testing of material mechanical properties、 appropriate methods should be selected based on the actual situation during sampling. The performance sampling of casting grouting sleeve materials should be done using a single cast test block、 while the performance sampling of grouting sleeve materials using mechanical processing technology should be done using raw materials、 and the sample preparation should comply with relevant standard specifications. When conducting hardness testing、 the casting grouting sleeve should use a body sample or a single cast test block under the same conditions for sampling.
