Objectives: To determine the strength and swelling behavior of black cotton soil (expansive soil) using a shredded rubber tyre as an additive. Methods: Series unconfined compressive California Bearing Ratio (CBR) tests were carried out on mixed with 0%, 5%, 10%, 15% tyres, results compared untreated samples. The study also investigated influence characteristics by performing pressure test. Find...

Anisotropy, which is characteristic of metamorphic rocks such as schists, is due to a process of metamorphic differentiation. Preferred orientation of minerals like mica and chlorite in response to tectonic stresses makes schistose rocks foliated. As a result their engineering properties vary with the direction of loading. The influence of transverse anisotropy on strength and deformational res...

Cement stabilization is one of the commonly used techniques to improve the strength of soft ground/clays, generally found along coastal and low land areas. The strength development in cement stabilization technique depends on the soil properties, cement content, curing period and environmental conditions. For optimal and effective utilization of cement, there is a need to develop a mathematical...

Conventionally, many researchers have used both regression and black box techniques to estimate the unconfined compressive strength (UCS) of different rocks. The advantage of the regression approach is that it can be used to render a functional relationship between the predictive rock indices and its UCS. The advantage of the black box techniques is in rendering more accurate predictions. Gene ...

Historically, deep foundations in weak rock have been designed as friction elements using frictional resistance (fs), calculated from the unconfined compressive strength (UCS) of rock. Most published correlations fs to UCS were developed based on load tests low-capacity piles specific geological conditions, values not necessarily representative over test depth. There is a large variation founda...

The use of industrial by-products as admixture to ASTM Type I cement (ordinary Portland cement (OPC)) was investigated with the objective of improving the solidification of organic marine clayey soils. The industrial by-products considered in this paper were oyster-shell powder (OSP), steelmaking slag dust (SMS) and fuel-gas-desulfurized (FGD) gypsum. The industrial by-products were added to OP...
