Abstract:

Relationships between the shrink-swell index and other clay tests, such as Atterberg limits have been investigated by others however, there is not any available information for the Wagga Wagga region in NSW Australia. This study’s objective is to establish some relationships between the shrink-swell index and Atterberg limits of the soils in the Wagga Wagga region. A total of 27 samples at different locations and depths was tested for shrink-swell index, linear shrinkage, liquid limit, plastic limit, plasticity index and soil particle size distribution, using Australian Standard test methods.

The properties of Swell-shrink of the soils in Kibaha were studied. Geotechnical and mineralogical tests were carried outon disturbed and undisturbed samples recovered from trial pits at different locations. Using empirical relationships, theswelling potential of the soil was established in correlation with the soil plasticity limits and grain size analysis (claycontents). The average values for the plastic, liquid and linear shrinkage limits for soils were 22.2%, 60.7% and 14.5%respectively.

Abstract:

A procedure is proposed for conducting shrinkage limit tests using a three-dimensional (3D) scanner. Shrinkage limit tests were conducted on 27 different soils of varying plasticity. In this study only eight of the shrinkage curves were determined using 3D scanning techniques, while the remaining 19 were taken from literature. An individual specimen was scanned between 30 and 50 times to produce a high-resolution shrinkage curve. Shrinkage curves for each material were obtained by curve fitting a shrinkage model to the measured dataset. The primary intent of the research was to relate the shri

In an injection moulded part, warpage is the distortion caused by non-uniform shrinkage within the plastic part. When looking critically at the causes of warpage, it is found that several key parameters of the moulding process have some effect on the warpage. However, the two major categories that contribute to warpage include the part design and the mould design. In mould design, the gate location, runner/gate system and cooling system design are the major factors affecting not only the warpage and part quality but also the injection moulding cycle time.

Abstract:

During its service life, concrete experiences volume changes. One of the types of deformation experienced by concrete is shrinkage. There are four main types of shrinkage associated with concrete: plastic, autogenous, carbonation, and drying shrinkage. The volume changes in concrete from shrinkage can lead to the cracking of the concrete. In the case of reinforced concrete, cracks in the cover concrete provide a direct path for chloride ions to reach and corrode the reinforcing steel. The development of concrete drying-shrinkage performance specifications with an associated test procedure was

The process of changing a soil’s physical characteristics to provide it long-term, permanent improvements in strength is known as soil stabilisation. Increasing a soil’s overall bearing capacity and shear strength is how stabilisation is achieved. After stabilisation, a solid monolith forms, reducing permeability and hence the possibility for shrinkage and swelling as well as the damaging impacts of freeze-thaw cycles.

Correlation studies in temperate soils have shown that there is a close association between Atterberg limits (AL) with the clay content, less information exists in the literature between the association of AL and other soil physical properties of soil (e.g. in situ water-content and soil particle density). The main objectives of this research were to:

The persistent failure of road pavements manifesting as severe cracks, potholes, partial or complete collapse has left residents of communities along the Mubi Bypass Road in Jambutu in a highly distressed and disrupted condition. A geotechnical investigation was conducted to determine the causes of road pavement failure within the study area. Particle size distribution analysis revealed a predominance of fines (25.9–30.8%) and sand (59.5–64%), suggesting the presence of silty clay and silty sand. Atterberg limits indicated low plasticity, with liquid limits ranging from 20.0–23.2%, plasticity

The earth’s swelling and shrinkage characteristics under varying moisture conditions make roads built on expansive CS, in particular, vulnerable to early degradation. In this investigation, coffee husk ash (CHA), gypsum, and a blend of the two additives (G-CHA) were used in experimental tests to treat expansive CS.

AbstractIn many areas of geotechnical engineering it is necessary to have an estimate of the cation exchange capacity (CEC) of a soil in order to allow preliminary design estimates. Standard methods of CEC determination are time-consuming and involve several steps (e.g. displacement of the saturating cation requires several washings with alcohol). Therefore, a rapid method of CEC estimation would be very useful. During preliminary site investigations, the soil engineering parameters can be estimated from the considerable number of correlations available in the literature. In this study, relati
