Sixteen-span prestressed construction made in 1961. Corrosion from road de-icing salts was detected in some of the prestressing tendons, necessitating initial closure of the highway even though further investigations had been completed.
Polymer concretes are usually useful for the repair and construction of other programs, for instance drains.
Bonded tendons encompass bundled strands put within ducts Situated within the bordering concrete. To ensure total protection to the bundled strands, the ducts must be tension-stuffed with a corrosion-inhibiting เสาไฟฟ้าคอนกรีตอัดแรง grout, without leaving any voids, pursuing strand tensioning.
The key to accomplishing a strong, tough concrete rests inside the very careful proportioning and mixing from the elements. A combination that doesn't have enough paste to fill the many voids concerning the aggregates is going to be tricky to location and may deliver rough surfaces and porous concrete.
A properly intended mixture possesses the specified workability for your fresh concrete plus the necessary durability and energy for the hardened concrete.
Large amounts in many cases are transported by truck, poured absolutely free less than gravity or through a tremie, or pumped through a pipe. More compact quantities may be carried within a skip (a steel container which may be tilted or opened to release the contents, normally transported by crane or hoist), or wheelbarrow, or carried in toggle baggage for handbook placement underwater.
