Center for By-Products Utilization PROPERTIES OF CONCRETE PRODUCED FROM MULTI-COMPONENT BLENDED CEMENTS
This paper presents a study on the behavior of concrete produced from multi-component blended cements. These blends were prepared by blending 20 percent to 60 percent ASTM Type I cement with the combination of Class C fly ash and clean coal ash. Two percent to four percent sodium sulfate anhydrite was added to the blends as a chemical activator. Tests were conducted on the prepared concrete for...
متن کاملCenter for By-Products Utilization UTILIZATION OF FLY ASH AS A CONSTRUCTION MATERIAL IN CHINA
China has one of the largest coal mining industries in the world. Electricity in this country is mostly generated by coal-fired electric power plants. These plants produce huge amounts of ash each year. In 1988, Shanghai city alone produced nearly 1.8 million tons of ash. During the last two decades, a substantial amount of research work conducted by the Shanghai Research Institute of Building ...
متن کاملCenter for By-Products Utilization Performance Testing of Controlled Low Strength Materials and Concrete Using High-Carbon Fly Ash
This project consisted of performance testing and evaluation of concrete and Controlled LowStrength Materials (CLSM) containing high-carbon fly ash. One of the aims of this project was to determine the feasibility of incorporating carbon fibers into CLSM and concrete mixtures to lower electrical resistance of these two construction materials. This is continuing work performed by the UWM Center ...
متن کاملProject 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...
