Most commonly, แผ่นพื้นสำเร็จรูป dam prestressing normally takes the shape of submit-tensioned anchors drilled into the dam's concrete construction, the underlying rock strata, or both. These kinds of anchors typically comprise tendons of substantial-tensile bundled metal strands or person threaded bars. A tendon is grouted on the concrete or rock at its much (inside) close and has a substantial de-bonded absolutely free duration at its exterior finish which makes it possible for the tendon to extend in the course of tensioning.
to six in. thick. Mortar Combine is often a mixture of superior performance Quick Set cement with top quality sand. Mortar Combine delivers remarkable resistance to chemical assault. It can be non-metallic and no chlorides are extra. Mortar Combine permits the restore spots for being painted, coated or sealed rapidly after software. Beneath dry circumstances, h2o-dependent coatings including latex paint could be applied once the solution แผ่นพื้นสำเร็จรูป is hardened, which generally usually takes 1-several hours to 4-several hours. Solvent-based and impermeable coatings for instance oil primarily based paint and epoxy is usually utilized in sixteen-hrs.
