Impact of dyeing industry effluents on geotechnical properties of soil

Abstract In developing countries concentration on pollutants produced by industries such as dyeing, tanneries industries are exceptionally high. The disposal of untreated industrial waste water similar to dyeing effluent on soil is a widespread practice in developing nations. The unprocessed effluents severely deteriorate the soil properties. The study on dyeing effluents from industries affects engineering properties of soil. Hence the soil properties have to be improved for intensification of soil for the constructional activities. The soil properties are very much exaggerated by dyeing effluent which produces the soil and water pollution. In this study textile industry effluent is taken as pollutants and laboratory experiments are carried. The affected soils were treated with marble dusts as admixture to improve the soil properties. For assessment polluted and unpolluted soil samples are treated with 20% of dyeing effluent and tests were conceded out to identify an extent of the contamination. The cured samples show a decrease in strength values up to 30% with raise in the percentage of infectivity (dyeing effluent). The geotechnical properties and their stabilization using marble dust are determined with mixtures and explored.

Properties Of Soil

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

Properties Of Soil

Soil Stabilization is the alteration of soils to enhance their physical properties. Stabilization can increase the shear strength of a soil and/or control the shrink-swell properties of a soil, thus improving the load bearing capacity of a sub-grade to support pavements and foundations. The Engineering Properties of soil are depended on the many points like minerals, water table, soil water behaviour etc. which vary as per area to area. Due to which we can’t get desire properties suitable to our needs of construction. To resolve this problem, we have technique called stabilization which means to stable or to modify or to improve the soil properties in positive manner. So, we can have a construction works which fulfil our needs and objective.

Properties Of Soil

Soil improvement is one of the most important problems to be solved for shielding tunneling in the complex strata. Now the foam modifying soils technique has been widely used in shield tunneling construction. A new foaming agent used for soil properties improvement is developed and presented in this paper. This paper presents test research of soil properties improvement on sand in rich-water strata and clay soils from permeability, fluidity, compressibility and shear strength. Compared with the imported and domestic foaming agent, the basic performances of the newly developed foaming agent are obtained. Some conclusions are drawn in the paper, and it is significant to improve the engineering properties of soil and reduce the ground damage in shield tunneling construction.
