Effect of Clear Edge Distance on Failure of Pile Cap
Abstract Depending upon shape and thickness of cap, soil strata, pile dimension, and locations of piles in pile cap, design and dimensioning of pile cap is a challenging task. A pile cap is a reinforced concrete structural rigid slab and, as per rivet formula, it...
Cement Composites with Wood Waste—Design, Features, and Proposal of Application
Abstract The paper discusses the possibilities of using ecological, organic materials such as sawdust and shavings for the production of lightweight cement composites. First, the method for determining the approximate constitution of such composites was proposed. A...
Experimental and Analytical Study on Punching Shear Strength of BubbleDecks
Abstract This paper presents an experimental and analytical investigation on the behavior of self-consolidating concrete (SCC) slabs with plastic bubbles under concentric and eccentric load. Twenty-four slabs of dimensions 1500 x 1500 mm (59 x 59 in.) with a total...
Qualification and Design of Cast-in-Place and Post- Installed Reinforcing Bar Anchorage
The recent revision of a guideline in the United States allows for the first time ever the qualification of post-installed reinforcing bars for end anchorages and overlap splices. The design of end anchorages and overlap splices with post-installed reinforcing bars...
External Restraint Factors in Early-Age Massive Foundation Slabs
Massive foundation slabs are one of the structures in which early age effects play a significant role. These effects are mainly related to the exothermic nature of cement hydration and a consequent temperature rise in the structure. The inhomogeneous volume changes...
tConcree Dtion egradadue to Moisture and Low- and High- Temperature Cycling
Based on a 10-year climate survey for Oklahoma City, OK, three exposure regimens were devised: cyclic high temperature exposure, cyclic freezing-and-thawing exposure, and cyclic wetting-and-drying exposure. A total of four different test methods were compared to...
Early-Age Cracking of Lightweight Mass Concrete
Abstract In this project, the effect of using lightweight aggregate (expanded slate) on the early-age cracking tendency of mass concrete mixtures was evaluated. Concretes representative of mass concrete mixtures—namely, normal-weight concrete, internally cured...
Predicting Chloride Testing Outcome of Different Cementitious Systems
Abstract The American Concrete Institute (ACI) specifies allowable admixed chloride limit (Climit) values to minimize the corrosion risk of steel reinforcement in concrete. The chloride concentration of concrete for new construction must not exceed this Climit value....
Alkaline Attack on Cement or Lime Mortar and Glass Fiber- Reinforced Polymer Rod
Abstract Glass fiber-reinforced polymer rods, both bare and embedded in concrete or lime mortar, were immersed in an alkaline solution at 20°C for up to 6 months and tested to find the influence of the protective covers on the degradation of the rods. Diffusion and...
