Project Title: Design and Evaluation of High-Volume Fly Ash (HVFA) Concrete Mixes Report C: Shear Behavior of HVFA Reinforced Concrete

Concrete is the most widely used man-made material on the planet. Unfortunately, producing Portland cement generates carbon dioxide (a greenhouse gas) at roughly a pound for pound ratio. High-volume fly ash (HVFA) concrete – concrete with at least 50% of the cement replaced with fly ash – offers a potential “green” solution. However, because it is still relatively new and has some disadvantages...

Influence of High Temperatures on Flexural Strength of Foamed Concrete Containing Fly Ash and Polypropylene Fiber

In this study, the elevated temperature flexural strengths of lightweight foamed concrete (LFC) containing fly ash (FA) and polypropylene fiber (PF) was investigated experimentally and statistically. The variables included were the temperature degrees (in a range of 20 to 600°C), LFC densities of 600, 800, 1000, 1200 and 1400 kg/m3 and additive content. Two mixes were made by replacing 15% and ...
