Post-tensioned slabPunching shearSlab-on-gradeIn the international and national practice of design, a different type of slab on the various types of grade are becoming increasingly common. For such structural elements, shrinkage and temperature influences in combination with low tensile stress, mainly...
Slab-on-grade foundation Slab-on-grade foundation As the name suggests, a slab is a single layer of concrete, several inches thick. The slab is poured thicker at the edges, to form an integral footing; reinforcing rods strengthen the thickened edge. The slab normally rests on a bed of cr...
In most cases, decorative concrete floors are only practical if there’s an existing concrete slab-on-grade or basement floor to work with. However, it is possible is to install concrete right over an existing floor covering, such as sheet vinyl, tile or wood, by using a decorative overlay...
When the slab is under curling-plus-load, it is observed that daytime curling significantly reduces the peak load capacity results in sudden failure of the slab whereas nighttime curling causes stable cracks and increases the peak load resisted by the slab. It is hoped that the application of ...
Moreover, the differential shrinkage along the thickness of the slab leads to upward curling on the edges of the slab [6–9]. Curling of concrete slabs-on-grade remains a major concern and its mitigation is critical for crack control, durability, and mechanical performance [10–13]. In ...
Is the slab of the basement ceiling a slab-on-grade? (assuming the ceiling slab is level 0m with thickness 200mm). Which is slab-on-grade? Replies continue below Recommended for you what exactly is a transfer slab? What is engineering simulation? Whitepaper: "Automotive System Design & ...
1.3.2.2.6 Concrete slab roof This type of roof was one of the most comprehensive roof systems in the years before the 1980s, due to its heavy weight and low execution speeds as well as its significantly low cost. Nevertheless, some design engineers are more likely to believe in this roof...
