PROBLEM TO BE SOLVED: To provide a construction joint method for inversely placed concrete, which facilitates setting and removal of a clad pipe, efficiently and positively fills a filler into a gap between a pre-cast concrete and a post-cast concrete and/or a cavity in a rear portion of ...
jointing is not taken seriously enough and the "sawcutter" comes to your job and puts the cuts where he feels they belong or where it is convenient for him. And, most plans don't have joint spacing marked on them. So don't leave this important part of concrete construction to chance....
A concrete construction includes a formed concrete slab having at least one control joint formed into a surface of the slab to control the location of stress cracks as the slab cures. A control joint protective strip is removably received in the control joint and has a head portion which over...
The partitioning plate 4 of the buried material 1 is located at a position corresponding to a placing joint part, and concrete is placed in both areas partitioned by the partitioning plate 4 so as to expose the upper part of the partitioning plate 4. Bar-like members 5 are desirably ...
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...
did not want. The remedy for this problem was to install the concrete within specified tolerances. In addition, specifying lower-shrinkage concrete materials, combined with tighter joint spacing, would significantly reduce the amount curling the concrete would exhibit....

The following types of movement joint are commonly used in power station construction: Contraction joint This type of joint is generally used in slabs and walls to permit contraction of the concrete. Initially there is no gap between the concrete on either side of the joint and the reinforcement...
Special attention was paid on the execution of the top joint, which was carefully filled with thin layer mortar. This leads to perfect and strong boundary conditions, which definitely cannot be assumed on all construction sites. The results of the pure out-of-plane tests show that both solid...
Modern construction is favouring the use of high strength materials which enable the use of smaller cross-sections and consequent larger usable floor spaces. These solutions possess higher slenderness values which make them more prone to instability problems. Because of this, further study needs to ...
