Numerical and laboratory investigation of effect of soil reinforcement on settlement of strip foundations

Article in Press

Reinforcement of loose soils with geosynthetics in order to achieve a strengthened soil-reinforcement system, with enhanced tensile strength and reduced settlement is an important subject in the field of geotechnical engineering. In this study, a soil reinforcement system was used to increase the bearing capacity of sandy soil beneath a strip foundation. A small-scale laboratory model was built to investigate the behavior...

Lithofacies and petrophysical properties interpretation of reservoir rocks in shaka field, Onshore Niger Delta

Article in Press

This research covers lithofacies and petrophysical interpretation of reservoir rocks using well logs and core data from Well SHA-001 to understand the reservoir quality with respect to their depositional environments. Analysis was carried out on core sample of 84.3 feet from a depth range of 7176 ft – 7260.3 ft in well SHA-001 to identify and interpret lithofacies depositional environments. Six (6) Lithofacies were...

New nano-structured microcrystalline silica: fire agate

Article in Press

30 samples of fire agate (SiO2) from Mexican new deposits (State of Aguascalientes, Calvillo and Jesus Maria municipalities) were documented using Raman Microprobe (RMP), Infrared reflection (IRS) Spectroscopy, Scanning Electron (SEM), and Atomic Force Microscopy (AFM). Fire agate, a non-transparent variety with multicolored fire, show a higher degree of organization of homogeneous nano-structure which is built from the...

Determining the optimum compressive strength of cemented paste backfill for artificial ground support in underground mines

Article in Press

This study was carried out to determine the optimum strength of cemented paste backfill for production of an economic backfill in an underground mine. Tailings samples from a copper mine, Namibia were collected and classified into three particle size range of +75µm, +150µm, +300µm for preparation of cemented-tailings paste. Tailings compaction was also carried out for a penetrometer (CBR) test to determine the optimum...

Estimation of Swelling Potential of Enugu Shale Using Cost Effective Methods

Article in Press

The behavior of swelling soils is mainly governed by its mineralogical composition as well as its environmental factors and stress history. Enugu Shale is one of these shales that assessment of its soil swelling potential cannot only be based on its mineralogical composition alone. The identification of its clay mineral types is basic to understand the roles of other factors of swelling in the soils. The results of...

Sedimentary facies analysis and depositional environments of the Buanji Group, Chimala (East), SW Tanzania

Article in Press

This work presents a facies analysis of Buanji Group based on field data. The succession is divided into two depositional sequences which are lower siliciclastic units (ranging between 600 – 750 m thickness) of the lower and middle Buanji and upper non-clastic – clastic strata (600 ± 20 m thickness) of the middle and Upper Buanji Units. Six lithofacies (conglomerate (F1), sandstone (F2), siltstone/mudstone (F3), shale...

PRELIMINARY INVESTIGATION ON THE QUALITY OF AMASIRI SANDSTONE (SOUTHEASTERN NIGERIA) AS CONSTRUCTION MATERIAL

Article in Press

The need to source for local construction materials that are appropriate for the massive developmental projects in Ebonyi State, southeastern Nigeria, has necessitated sampling and testing of the Maastrichtian Amasiri Sandstone in the Akpoha area of the state. Petrographic analysis and aggregate tests were conducted on six samples randomly selected from the rock deposit underlying the area. The petrographic analysis...
