Comparative study of coral sand and silica sand in creep under general stress states
Canadian Geotechnical Journal, 2017Coral sand has individual characteristics that differ from silica sand, such as creep behavior that is always attributed to particle crushing under high stress states. To understand the creep behavior of coral sand under general stress levels, three series of comparative triaxial tests relevant to the deviator stress, confining pressure, and relative ...

Settlement Reliability Analysis of Gravity Foundation in Coral Sands
2011 International Conference on Computational and Information Sciences, 2011Settlement calculation is an important work in design of foundation of building structure. In this paper, the reliability method is used to analyze the settlement of gravity foundation in coral sands. By calculating settlement using secant modulus method, performance function of settlement reliability analysis of foundation is established. JC method is

Construction and Building Materials, 2018
Abstract The present study investigates the chloride ingress and binding behaviors of coral waste filler-coral waste sand marine mortar and the influence imposed by metakaolin (MK) addition. The mortars were cured for 4 months and followed by exposing to 0.5 M sodium chloride solution for 45 days.

Tunnelling and Underground Space Technology
Coral sand, as a geological material for foundation filling, is widely used for reclamation projects in coral reef areas. The coral sand is characterized by a wide grain size distribution. A series of centrifuge shaking table tests were conducted to explore the seismic response of a shallow buried underground structure in saturated coral sand and coral

Strain rate-dependent undrained response of a coral sand
Géotechnique LettersThe strain rate-dependent response of sand is influenced by particle crushing. However, such a conclusion is drawn in the previous studies, primarily based on drained triaxial or 1D compression tests on crushable sand. This study explores the interplay of strain rate and crushing behaviour of sand under undrained triaxial (CU) conditions.

Effects of sand deposition on scleractinian and alcyonacean corals
Marine Biology, 1995The ability of corals to withstand experimental sand deposition was investigated for two experimental periods (17 h and 6 wk) in eight scleractinia (Favia favus, Favites pentagona, Platygyra daedalea, Gyrosmilia interrupta, Galaxea fascicularis, Cyphastrea chalcidicum, Favites abdita, Goniopora dijboutensis) and five alcyonacea (Lobophytum depressum, L.
