4.3 Carbonate soil
A soil containing more than 50% by weight of carbonate compounds (such as calcium carbonate).
4.4 Cemented soil
A soil bound with a cementing substance, such that if remoulded and recompacted to its original density and moisture content, exhibits a significantly lower strength than in its undisturbed condition.
4.5 Classification
A system which places a material into one of a limited number of groups on the basis of a defined characteristic or set of characteristics. For example, a soil classification may be based on the grading and plasticity of disturbed samples.
4.6 Cohesive and non-cohesive soils
Soils are conveniently divided into two groups based on the ability of a soil mass to hold together. Those capable of holding together are termed ‘cohesive’ and those having no ability, or strength, to hold together by themselves at very low applied total stress levels are termed ‘non-cohesive’.
4.7 Competent person
A person who has, through a combination of training, education and experience, acquired knowledge and skills enabling that person to correctly perform a specified task.
4.H Consistency
The ability of the soil, at specific moisture contents, to resist mechanical stress or
manipulation (remoulding).
4.9 Contamination
The condition of land or water where any chemical substance or waste has been added as a direct or indirect result of human activity above background level and represents, or potentially represents, an adverse health or environmental impact. Contamination may have an impact on human health during construction or the service life of a structure erected on the site or may have detrimental effects on the environment.
NOTE: VhiIe this Standard does not address investigation of the presence of contamination or management of such contamination, the possibility of the presence of contamination should be considered during the planning and conduct of geotechnical site investigations.
4.10 Controlled fill
Any fill for which engineering properties are controlled during placement. Sometimes
referred to as structural or engineered fill.
4.11 Description, soil or rock
A statement of the physical characteristics of a sample of soil or rock.
4.12 Desk study
A study to collate and review the existing information relevant to the site.
4.13 Dispersive soils
Those soils, which by nature of their mineralogy and pore water chemistry, are susceptible to separation in water of individual clay particles.
