This paper compares some geotechnical properties of Kaolin, Laterite and Peat. Laterite was collected from Bukit Banang while Peat sample was collected from Parit Nipah, both locations were in Batu Pahat, Johor. Meanwhile, kaolin that was used in this research was manufactured kaolin. These soil samples were subjected to routine laboratory analysis and resulting data were analyzed statistically using a correlation analysis. A laboratory testing program consists of “Basic properties test” to obtain general information on the materials (e.g Natural moisture content, Atterberg Limit, Specific gravity, grain size analysis, chemical composition and pH) and “Geotechnical properties tests” to measure specific properties that characterize soil behaviour for design and constructability assessments (e.g Standard Proctor Test, Unconfined Compressive Strength and CBR).The results showed that the Natural/initial moisture content for laterite, peat and kaolin is 22.54%, 480.61% and 0.22% respectively. Meanwhile Specific gravity for each soil was in the range 1.50-2.79.It was also found that the pH of all soil is acidic which lay in the range of 3.76-5.95.The UCS for the optimally compacted sample of laterite is 445.77 kPa, kaolin is 199.23 kPa and for peat is 58.70 kPa. This paper summarizes the result of analysis performed on all tests conducted. Based on the results, the geotechnical property of the soil is a highly dependent with the type of soil and therefore, determining the soil characterization and the soil strength should be considered during the planning phase of any earthwork construction operation.

Lateritic soils that overburden Mohammad Buhari Estate in Abeokuta area of Ogun State, Nigeria is in great use for road construction. However, little is known of their geotechnical properties and suitability as base, sub-based and sub-grade materials for road construction. This study is aimed at utilizing in accordance with regulatory standards of Nigeria, the geotechnical techniques to investigate the properties of this lateritic soil. The samples were collected at 0. 25m deep at different locations and were subjected to the following laboratory test; Particle size analysis, Atterberg limits test, Compaction test, Californian Bearing Ratio test, Moisture content and Specific gravity test. The result shows un-soaked CBR test from 12.52-55.84 %. The specific gravity results range from 2.57-2.89 while the optimum moisture content and maximum dry density range from 18.20-28.30% and 1.48-1.81mg/m3 respectively. The liquid limit, plastic limit and plastic index ranges from 12.0 to 40.1%, 10.0 to 22.0% and 2.8 to 20.4% respectively. This implies that lateritic soil present throughout the study area is suitable for use as sub-base and base materials since the geotechnical properties are fairly within the regulatory standards of Nigeria.

The study is related to the comparison of soil characteristics in some areas from a depth of 1m, 1.2m, and 1.5m; physical and geotechnical properties of the soil samples are studied in the laboratory to develop a simple method to determine the type of soil on a site. The tests conducted are grain size analysis, specific gravity, and field density. Moreover, the research intends to validate the behavior of sieving systems for different types of soils and at various loading conditions. From work, a decision support system to facilitate a sieving system that integrates geological, geotechnical, and structural factors is developed. The study reveals that an increase in the plasticity index decreases the angle of internal friction. The empirical models developed with the help of regression analysis for the benefit of field engineers for predicting the geotechnical properties.

Scrap Tire Rubber

An experimental work was undertaken to study the effect of rubber tires on the geotechnical properties of a dredged sediment, using a mixing ratio of large size. For comparison, two types of soil were studied (dredged sediment from Fergoug dam and Tizi Tuff from the north west of Algeria). Taking into account the high compressibility and the low water absorption of the rubber tires, grain size analysis, density, Atterberg limits analysis, chemical composition, direct shear tests, loading-unloading tests, modified Proctor and CBR tests are performed on the two soils and their mixtures with different scrap tire rubber (10, 20, 25 and 50%). The results show that liquid limits and plastic indexes decrease with the scrap tire rubber content and that the decrease is more significant for soil with high plasticity. Cohesion also decreases with scrap tire rubber content when the internal friction angle is vacillating. Compression and recompression indexes increase gradually with the scrap tire rubber content and the variation for compression index is more significant for the two soils. Compaction characteristics and CBR values decrease with scrap tire rubber content. The CBR values for W=3% are important compared to those with W=5% excepted for mixture with (75% tuff and 25% scrap tire rubber). The results show that the scrap tire rubber can be used as a reinforcement material for dredged soil, but with a content that should not highly affect the compressibility.

Moisture content is an important factor affecting the geotechnical properties of solidified municipal sludge (MMS). Typical municipal sludge in China was chosen to investigate the effects of initial moisture content (defined as w0) on geotechnical properties of MMS solidified by self-developed CERSM solidifying agent. In addition, the microstructure changes of solidified sludge samples in this study were explored with scanning electron microscopy and mercury intrusion porosimetry. Mechanical experiment results showed that the unconfined compressive strength, cohesion, and internal friction angle of the MMS increased with the decrease in initial moisture content, but the permeability coefficient changed oppositely. The permeability coefficient of solidified sludge samples was between 10−8 and 10−10 cm/s. But after the drying-saturated process, the permeability coefficient of MMS can be increased up to 4 times, mainly due to the formation of a considerable number of microconnected pores and microcracks in the process of drying. The research results are of great significance to the safe disposal and utilization of municipal sewage sludge in China.

Four sites with different depth in AL-Fursan area/ North Tikrit city were selected for recent deposits sampling. The geotechnical properties of soil were tested and improvement of engineering properties of soil by cement was carried out. The geotechnical properties  test results revealed that the moisture content ranges between (0.53 -1.45)% which is low because of  sampling in summer season, while the grain size analysis show that the soil at the study area is coarse soil (sand) with fines. The soil type in the first site is clayey sand (SC), the second site contains sand with equal percentage of silt and clay (SC- SM) , the third and fourth site types are silty sand (SM). The specific gravity ranges between (2.46- 2.72) sites (1,2,3) are low liquid limit and low swelling index but the fourth site is moderate. The value of cohesion strength for the four sites are (16, 13, 1, 8)kPa respectively, sites (1) and (2)  are moderate cohesion while sites (3) and (4) are non-cohesion, none plastic and un active. The low values of cohesion strength belongs to high percentage of coarse particles in the area. The values of internal friction angles ranges between (300- 370). The consolidation test results revealed  that all sites were moderate compressive index except the first site which is low compressive and low swelling. The study area soil are neutral and high content of gypsum and soluble Dissolved salts and also high organic content. The soil improvement by cement tests results show increasing of cohesion and internal friction angle and the compaction test results show the samples are well sorted.   http://dx.doi.org/10.25130/tjps.24.2019.087

Overburden is the unutilized rock or soil bands that are generated during the mining process and are dumped near the marked placed inside the mine boundaries. It contains alluvial, sandstone, soil, gravel, clay, debris other than mining material. Dumping or management of this mine waste is a significant environmental problem, and additional cost spends to the mining industry. And also, most of this waste is disposed of at the surface, which inevitably requires extensive planning. Sand and gravel are low energy-intensive construction materials, but the growing demand for industrial uses has depleted this natural source. Limitations to natural sand extraction and legal regulations have been imposed in several countries due to environmental concerns. Due to the above, all the reasons river sand has become very costly in recent years. The research has been carried out to convert the overburden to processed overburden sand after that compared the geotechnical properties like specific gravity, permeability, moisture content, and grain size analysis, swell factor of both the overburden processed sand and natural river sand. Then we check the suitability of processed overburden material as a replacement to natural river sand in construction by comparing the strengths of the concrete samples prepared with both the river sand and processed overburden sand. We found the average compressive strength of overburden sand brick is 24.69 MPa, and river sand brick is 28.08 MPa of 14 days curing of bricks. The results obtained that the processed overburden sand can be used as the best alternative for the river sand because the geotechnical properties of both are almost the same. This processed overburden utilization in the coal mining area to reduced environmental impact, more availability of a land resource, minimizing the overburden disposable cost to the mining industry, and it’s also helpful to the preservation of natural river sand.

This study investigates variation of termite mounds in relation to the control soils around our environment that are not hindered by the termites at various locations at The Polytechnic; Ibadan, Oyo State, southwest Nigeria. From the study area, five termitaria were selected at random. At the core of termitaria, soil samples were taken at a distance of 7.5m and 15m to the both side of termitaria. Twenty five (25 soil samples were collected in all and were subjected to geotechnical properties such as natural moisture content, grain size analysis, california bearing ratio (CBR) test, Atterberg’s limits, and unconfined compressive strength test. The results proved that termite mound soil have better geotechnical properties compared to surrounding control soil. The betterment was attributed to the activities of termites in termitaria thus increasing the strength parameters present in the soil.

Periwinkle Shell

The use of the periwinkle shell in the production of lightweight concrete has been studied and accepted to be used for concrete works. Hard water containing detergent-like chemicals has been observed to be used in mixing locally produced concrete. This exploratory study is on the effect of water mixed with detergent in a concrete prepared with the periwinkle shell as a coarse aggregate. A total of 27 concrete cubes of size 150mmx150mmx150mm were prepared in the laboratory with a mix ratio of 1:2:4. A water-cement ratio of 0.4 was used with the addition of detergent at varying percentages (0%, 0.3% and 0.6). The cubes were cured in water and tested at 7days, 14days and 28days respectively. Laboratory tests, which includes bulk density, specific gravity, grain size analysis, slump and the compressive strength test was carried out on the aggregates and concrete. The periwinkle shell had a bulk density of 1440kg/m3and a specific gravity of 2.50. The workability tested revealed that the slump values increased with increase in the percentages of detergent. The compressive strength at 28days and at 0.3% and 0.6% were 12.58N/mm2 and 14.06N/mm2 respectively. It was observed that the compressive strength decreased with the addition of detergent because of the tiny air bubbles introduced into the concrete by the detergent. From the results of the study, it can safely be concluded that the use of detergent contaminated water in concrete production will reduce its compressive strength and increase its workability.
