RCC - Roller-Compacted Concrete with hematite aggregate

نویسندگان

چکیده

RCC using hematite as an aggregate has interesting characteristics for use in massive structures or radiation shielding. In Brazil, there is a considerable amount of ore tailings without practical use, which makes this material environmental problem and matter public safety. Thus, the search alternatives to these priority concern. An containment dam with was constructed protect basin Barao de Cocais River, including city State Minas Gerais from possible rupture Sul Superior Congo Soco iron mine. Approximately 150,000 m3 deposited three months. article, results technological control tests during construction are presented compared cores extracted after construction, showing their coherence strength performance conventional aggregate. Also, studies related shielding presented. attenuation 10% 1.6 MeV gamma relation concrete observed.

Investigation of Nonlinear Behavior of Material on Seismic Performance of Roller Compacted Concrete Dam

In this research, the effect of nonlinear behavior of concrete on seismic performance of roller compacted concrete (RCC) is discussed. Nonlinear behavior of material shows the behavior close to reality due to use of all structural capacity and it is considered the most appropriate method for design. So in this paper, by using the appropriate definition of nonlinear behavior of RCC, the Ansys so...

Investigating the Effect of natural Pozzolans on Mechanical Properties of Roller Compacted Concrete

Roller Compacted Concrete (RCC), is a concrete with zero slump, which is used in damming and road pavement. Roller Compacted Concrete Pavement (RCCP) bear heavy traffic loads and severe weather conditions. This type of concrete is due to its economic and environmental capabilities, including reduced construction and maintenance costs, longer durability and longer lifetime, as well as environmen...
