Construction joints in a concrete component are sealed by a joint plate consisting of a backing plate (7) covered with a sealing layer (8), consisting of a fibre mat impregnated with a sealing material. Preferably the sealing material comprises a water-rejecting material or a swellable material...
1.The positions/locations of construction joints shall beproposedby the contractor.(Refer toCONCRETE ZONING FOR PLAZA, TOWER A & B,SBC-Alix- Sequence of Work for Podium Submit) 2.All kind of construction joints must be as per approved shop drawings.At the construction joint location, the surf...
This specification relates to apparatus and method for improving construction joints in reinforced concrete structures. A coupling member extends a short distance beyond the joint between two pours and has edges which mechanically couple to joining or adaptor members on the ends of reinforcing bars.收藏...

PURPOSE:To prevent water-leakage from a laitance layer generated on the surface of the primary concrete by relatively simple work when a cut-off material is used for a construction joint between the primary and the secondary concretes. CONSTITUTION:When the primary concrete 2 is solidified, a la...
Before the concrete is poured, isolation joint material is placed adjacent to the elements needing separation. As we’ve discussed, this could be at the junction of the exterior wall, staircases, columns, or footings. This material should be measured, cut, and placed at every area the pour ...
1.A joint where two successive placements of concrete meet. 2.A separation provided in a building which allows its component parts to move with respect to each other. The cause of such movement may be thermal, seismic, or wind loading. ...
混凝土施工冷缝的预防及处理(Prevention and treatment of cold joint in concrete construction) Prevention and treatment of cold joint in concrete construction Concrete is a kind of porous gelatinized stone. It is a rigid body. It is characterized by high compressive strength, low tensile strength, ...
The objective of this study is to examine the mechanical properties of construction joints between existing and newly placed concrete under combined tensile and shear stresses. Loading tests are conducted by using push off type specimens. The joint surface of existing concrete is roughened by shot bl...
Joint Construction and Seismic Performance of Concrete-Filled Fiber Reinforced Polymer Tubes. (Under the direction of Amir Mirmiran) Extensive studies in the past decade have shown superior performance of concretefilled fiber reinforced polymer (FRP) tube (CFFT) under axial compression, as the system...
