This paper reports the results of a study conducted to determine influence coarse aggregate type on workability, compressive strength, and flexural strength normal high concretes with target 28-day strengths 30 60 MPa two water/cement ratios 0.44 0.27. The were prepared using four types natural aggregates, namely diabase, calcareous, river gravel, basalt, maximum particle sizes 12.7 19.1 millim...

The mantle beneath coastal SE China evolved from enriched to depleted between the Cretaceous and Neogene, although precise timing of this change remains unclear. Here, we focus on a newly discovered Eocene mafic volcanic neck that contains peridotite xenoliths in Fuding area Fujian Province, present new whole-rock Ar–Ar data which indicate flood basalts formed during (ages 38.5 ± 1.2 42.3 2 Ma)...

Low-cost, grid-level energy storage is key to maximizing the utilization of renewable production and decarbonizing electricity sector. The design testing a high-temperature thermal based on rocks presented. Important features are three electric heaters mounted top inner pipe inside rock bed, allowing for first time reversible vertical air flow configuration system which partially underground. b...

Coupling between erosion and tectonics are thought to play a determinant role in mountains evolution. Here, we investigate the interplay in this coupling between the assumed erosion law and the crustal rhe-ology at the margin of a collisional plateau, like the Himalaya of central Nepal. Lithospheric deformation is calculated over a time scale of 100 kyr by a two-dimensional finite elements mode...
