Investigation of effect of size and content of nano/SiO2 on the strength and durability of RCC in freezing-thawing cycles [PDF]
مهندسی عمران شریف, 2022 RCC remains a widely used construction material over the last decade. RCC is placed in a manner similar to paving; the material is delivered by dump trucks or conveyors, spread by small bulldozers or specially modified asphalt pavers, and then compacted ...

Modelling heat exchange between RCC dam and reservoir [PDF]
Proceedings of the Institution of Civil Engineers - Engineering and Computational Mechanics, 2010 Temperature control plays an important role in the design and construction of roller-compacted concrete (RCC) dams. Hydration of cement and climatic changes on the convective boundaries are the two main heat sources of the temperature rise in RCC dams.

Optimal placement of smart sensors for RCC dams structural health monitoring using Monte- Carlo [PDF]
مهندسی منابع آب, 2020 Building RCC dams involves pouring and compacting concrete in small layers (30 cm), one on top of another, creating a joint between each layer. This joint could potentially become the “ideal” joint depending on the temperature and lag time between each ...
