Suitability of Large Sized Compacted Baked Clay Blocks as a Walling Material

Dynamically-compacted cement stabilised soil blocks for low-cost walling

Determination of Compacted Clay Permeability by Artificial Neural Networks

In many civil engineering practices like design of landfills, earth dams, pavements and agricultural issues, it is necessary to know the permeability coefficient of soils. In situ tests are frequently used to predict permeability of the soil. On the other hand, high ability of Artificial Neural Networks (ANNs) in prediction of nonlinear behavior has attracted the attention of many researchers. ...

Mechanical interaction between swelling compacted clay and fractured rock, and the leaching of clay colloids

We consider the interaction between a saturated clay buffer layer and a fractured crystalline rock engineered disturbed zone. Once saturated, the clay extrudes into the available rock fractures, behaving as a compressible nonNewtonian fluid. We discuss the modelling implications of published experiments carried out in Sweden and more recently in Japan. Extrusion is halted either when the advanc...

Interactive aggregation and sedimentation of diatoms and clay-sized lithogenic material

Monospecific diatom cultures (Thalassiosira punctigera and Skeletonema costatum) were incubated in rotating cylinders together with clay suspensions, present in a range of concentrations (5–100 mg kaolinite L21) and as different minerals (50 mg L21 kaolinite, smectite, illite, and clay-sized quartz powder). The addition of lithogenic suspensions to diatom cultures accelerated the formation of v...

Potential of Marine Clay as Raw Material in Geopolymer Composite

In this research, marine clays has been studied its potential as a matrix composite materials that tend to be used as alternative materials to concrete. The study shows that marine clays which mixed with appropriate proportion of alkaline activator could have strength requirements for masonry cement. The alkaline activator that been used for the geopolymerisation reaction is sodium silicate and...
