NG28 provides Party A's full-process quality control related concrete compressive strength testing (rebound method) service. Concrete rebound is the main non-destructive measure of concrete compressive strength. Damage detection method. The measured strength of concrete is the key factor and key parameter for evaluating the performance of concrete structures and components. The rebound detection of a certain number of building floors in the bidding section can reflect the overall structural entity of the project.

NG28 provides Party A's full-process quality control related concrete compressive strength testing (core drilling method) services. Concrete core drilling is the main damage detection method for measuring the concrete compressive strength. It can be used to determine the estimated value of concrete compressive strength of the test batch or individual component, and it can also be used to modify the converted value of concrete compressive strength obtained by the indirect strength test method by the core-drilling correction method. The measured strength of concrete is the key factor and key parameter for determining and evaluating the performance of concrete structures and components.

NG28 provides component scanning services related to Party A's full-process quality control. The component scanning includes the inspection and inspection of the thickness of the steel bar protection layer and the steel bar spacing. The detection range is mainly the components and parts where the position of the steel bar may significantly affect the bearing capacity and durability of structural components, such as the longitudinally stressed steel bars of beams and slab components. Component scanning reflects the physical performance of the structure from the perspective of the steel reinforcement in the concrete structure.

NG28 provides Party A’s full-process quality control related component size deviation detection services. The component size deviation detection is mainly to reflect whether the size of the main structural component meets the design requirements, so as to find whether there is a size deviation that affects the structural performance and use performance.

NG28 provides Party A’s full-process quality control-related pull-out test services for concrete post-anchors. Post-concrete anchors refer to the use of mechanical anchors, chemical anchors and bar-planting technical means to anchor on existing concrete structures. The tensile test of concrete rear anchors is an on-site test to detect the anchoring bearing capacity of these rear anchors. So as to determine the safety and reliability of the bearing after the anchor is put into use.

NG28 provides Party A’s full-process quality control related external wall tile on-site pull test service. The external wall tile on-site pull test is to use the bonding strength tester to pull out the external wall tile that has been laid. The inspection project site The bonding strength between the exterior wall facing bricks and the base layer. So as to avoid the quality risk caused by the unqualified bonding strength.

NG28 provides the on-site pull-out test service for the bonding strength of the insulation board and the base layer related to the quality control of the whole process of Party A. The on-site pull-out test of the bonding strength of the insulation board and the base layer is performed by using the bonding strength tester to the already laid external wall The thermal insulation system conducts a pull-out test to detect the bonding strength between the thermal insulation board and the base layer on the project site. So as to avoid the quality risk caused by the unqualified bonding strength.
