Study on Assessment of Pozzolanic Activity: Slate Cutting Waste
Abstract The mining industry is responsible for various environmental problems, including the extraction of natural resources and the generation of a significant volume of waste. The use of such residues in the construction industry as supplementary cementitious...
Deformability of Reinforced Concrete Columns Failing in Shear after Flexural Reinforcement Yielding
Abstract Previous post-earthquake studies on reinforced concrete (RC) structures have reported severe structural damages in the plastic hinge regions of lower-story RC columns, and suggested that columns with short shear-span ratios may fail in shear after flexural...
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...
Investing in Team Culture Helps Retention and Your Bottom Line
One of the biggest expenses for most companies is their staff. Paying salaries and insurance benefits — as well as other expenses like uniforms, equipment and vehicles — add up to a large percentage of any company’s revenue. When you look at those numbers, it can be...
