During the last decades eco-friendly, low-cost, sustainable construction materials for utilization in civil engineering projects have attracted much attention. To this end, soilcretes are non-conventional construction materials produced by mixing natural soil such as natural clay or limestone sand with a hydraulic binder and are recently under detailed and in-depth investigation by many researc...

A new species of abertellid sand dollar, Abertella miskellyi n. sp., is described from the Miocene Camarones Formation of Patagonia, southern Argentina. The new taxon corroborates the existence of the genus in South America, given that Abertella is most common in the southeastern USA and the eastern coast of Central America. It is characterized by a unique basicoronal circle, in which the inter...

the ground improvement using plastic board drain (pbd) in soft soil was undertaken by sand mat formation, pbd installation, preloading surcharge, and removal of surcharge. during this procedure, the sand mat formation induced an initial settlement. however, it was very difficult to estimate that settlement due to pbd installation, which frequently destroyed the instruments installed in the grou...

The present study analyses the distribution and diversity of sipunculan species inhabiting soft substrata in the Gulf of Valencia and Cape Nao (western Mediterranean) in relation to the characteristics of the sediment. Eighty-seven stations in 14 localities were sampled annually from 2004 to 2008. Nine species were reported, with Aspidosiphon (Aspidosiphon) muelleri being the dominant species i...

To study the influence of sand particles on strength and dry–wet cycle characteristics cement-solidified South China coastal soft clay, a series clay samples with different contents sizes were prepared, unconfined compression (UCS) tests, tests under seawater freshwater conditions, scanning electron microscopy X-ray diffraction carried out. The test results show that UCS cement–sand-solidified ...

The propagation of near-failure, soft-fronted stress waves in 5-foot-long, 1-inchdiameter, unconstrained rods of dry 20-30 Ottawa sand is studied. The input is created by a shock tube, modified to yield soft-fronted, long-duration, airpressure loadings. Primary data are displacement-time histories from seven stations along the rod, read by light-sensing gages designed for negligible inertia and...

Lightweight sand–EPS soil (LSES) is regarded as a kind of sustainable geomaterial for providing way to reutilize fast-growing waste expanded polystyrene (EPS) packages. It usually applied in marine geotechnical engineering solve the excessive settling soft ground or bumps at bridge heads due its merits such low density, high strength, and adjustability. Aiming investigate dynamic shear strength...
