Product Characteristics
• High compressive strength |
![]() |
• After curing, the color is close to that of concrete, and there is no obvious color difference.
• The early compressive strength is high, up to 30MPa in 12 hours.
• Good bonding performance to ensure the strength of the splicing seam.
• It can be glued and can be bonded for a long time. It is not affected in a humid environment and is convenient for construction.
• Good squeezable performance, which is conducive to the uniform coverage of the bonding surface with the colloid.
• Non-volatile, no shrinkage.

How to Use HM-120SC Segmental Bridge Adhesive
--Seal ring installation. Install a high-compressibility sealing ring at the pre-stressed nozzle of the precast section to prevent the glue from entering the pre-stressed pipe.
--Segment in place.The bridge building machine is ready, and the segments are hoisted into place in the order of splicing.
--Section cleaning. Polish the splicing surface concrete to ensure that the splicing surface is flat and clean.
--Segment tryout. Perform segment trial splicing to check and ensure that the pre-stressed pipeline is unobstructed. Lock the assembly angle and move the segment outward a proper distance to facilitate the application of glue. --Segment tryout
--Glue preparation. Prepare Hummer segment splicing glue according to the specified ratio and stir at low speed until the color is uniform.
--Glue application. Spread the Hummer segment splicing glue evenly on the splicing surface within the specified time, and the total thickness of the glue layer is 2 to 3 mm. In order to speed up the progress, several working surfaces can be painted and scraped at the same time.
--Formal stitching. The segments are formally aligned and spliced.
--Pressure to gather. Install Hummer temporary pre-stressed tensioning device to apply pressure to the splicing seam by about 0.2-0.3MPa, so that the two sections are gathered and compressed until the splicing glue overflows from the glue seam, and the glue seam width is controlled to be about 1mm.
--Glue cleaning. Clean up the spilled glue to ensure that the prestressed pipe is not blocked.
--Cure curing. During the curing process, avoid disturbance and take protective measures.
