Inside the Empire State Building’s 21st Century Upgrade
Constructed during the onset of the Great Depression, the Empire State Building became a symbol of American innovation and a marker of what the United States could achieve, even during its darkest times.Standing as the world’s tallest building for 40 years of its...
Thermo-mechanical and Durability Properties of Expanded Perlite Aggregate Foamed Concrete
Author(s) Sakir Sharook, MTech Dhanya Sathyan, PhD Mini K. Madhavan, PhD Abstract The thermal conductivity of a material is a measure of its capacity to conduct heat and is a major factor influencing heat transfer in buildings. For better thermal insulation,...
Concrete Moisture Diffusivity Determination Using Electrical Resistivity Measurements
Author(s) Gasim Alaswad, BSc, MSc Abstract The movement of water in concrete structures and buildings is a fundamental subject and therefore it is necessary to understand the mechanisms and processes involved. This paper presents a method to estimate the...
Strength and Hydration of Metakaolin-containing Ultra-high-performance Paste
Author(s) Zongyun Mo, MS Ligai Bai, MS Xu Fu, PhD Abstract The influence of metakaolin (MK) addition on the mechanical and hydration performance of ultra-high-performance (UHP) paste was investigated. UHP mortars were prepared to evaluate the compressive...
Improving the Performance of Porous Asphalt with Reclaimed Asphalt, Dune Sand and Lime
Author(s) Ahmed Siala, MS Saloua El Euch Khay, PhD Amara Loulizi, PhD, PE Jamel Neji, PhD Abstract A porous asphalt pavement is an open-graded asphalt mix that allows rainwater to drain through the surface layer. When designing a pavement structure, the porous...
Engineering and Durability Properties of Slag–dolomite Geopolymer Mortars
Author(s) Affiliations Abstract Ground-granulated blast-furnace slag and dolomite are by-products from the steel manufacturing and rock crushing industries, respectively. The addition of dolomite to a slag-based geopolymer matrix can improve its engineering...
GoSun cooks up Off-grid Tiny House with Elevating Bed
Brief GoSun is perhaps best known for its line of solar ovens and other neat outdoor gear. However, the firm has now completed an off-grid tiny house named the GoSun Dream that features a compact interior layout with an elevating bed. Insight GoSun is perhaps...
Analysis and Design of Double-Beam Coupling Beams
Author(s) Youngjae Choi and Shih-Ho Chao Abstract Double-beam coupling beams (DBCBs) are a viable alternative to diagonally reinforced concrete coupling beams (DCBs). While construction time and effort of DBCBs is much less than DCBs, their ability to sustain...
Behavior of Foamed Concrete Slabs Using Various Reinforcement Schemes
Author(s) Rabab Allouzi Abstract Foamed concrete exhibits enhanced mechanical, thermal and acoustic characteristics. Such properties seem to be a suitable alternative to fit evolving properties required in the housing industry. The main challenge is to select a...
