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...
Based on a mathematical approach, Westergaard (1926, 1927, 1943, 1948) derived formulae that predicted the state of stresses and strains in concrete slabs on grade subjected to temperature variations. Although Westergaard made various assumptions, his approach remained a basic tool for the design ...
It consists of a concrete slab or an asphalt slab resting on a foundation system formed by several overlapping layers of finite thickness (base, sub-base and sub-grade). From: Resources, Conservation and Recycling, 2015 About this pageAdd to MendeleySet alert On this page Definition Chapters ...
The information in this section will guide you through the steps required to build high-quality concrete slabs on grade and help you avoid mistakes that can lead to poor performance, or even worse, slab failure. You’ll also find advice on concrete mix design and calculating the water-cement...

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 ...

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...
Bending of the slab under such loading triggers the spalling/scabbing of the concrete without penetration of the impacting load [2]. In general, the mode of failure of the slab under impact loading depends upon the applied force, boundary conditions, and other design parameters of the slab [...
