The applications of pre-cast concrete in flat-slabs are mainly controlled by the construction joint between the slab elements and columns in order to satisfy monolithic action. This paper introduces a conceptual approach for the construction detail of such joints. An experimental program was conducted...
The support condition of cement concrete pavement slab is directly related to the serviceability pavement. A common manifestation of the deterioration of support conditions is the voids beneath the concrete slab. This is because the cement concrete pavement has free edges and joints, and rainfall or...
However, the global performance of composite joints is markedly affected by the structural interaction between the concrete slab and the steel components and - especially during seismic events - struts can occur in the slab at the beam-to-column intersection. In this paper, the possibility of ...

Filling a joint gap with a concrete slab joint sealant helps to support the joint and prevent arris damage, both for saw-cut joints and armoured joints.

Consequently, the voided slab system has been adopted in building design units and by technicians for its advantages of low concrete consumption, considerable floor-to-floor height, and expeditious construction with a high degree of quality control [24]. However, for engineers to employ this system...
It showed that damage occurs in the joints when the temperature of the track slab exceeds 37 °C. In addition, it was also found that the interface separation near the joints and the track deformation emerges due to the temperature gradient and pier settlement, respectively. Li et al. [14]...
There are many reasons why concrete cracks. But, in general, concrete cracks are due to the lack of expansion and contraction. Other reasons include excess water in the mix, quick drying of the concrete, and lack of control joints. It is also important to know that concrete comes in differ...
These cement bonding agents are also used to make repairs, like joining new concrete to old concrete, spraying concrete at construction joints, or using cement-sand repair mortar to make a strong bond. Most of the times, bonding agents are used in concrete when the old and new concrete ...
