Several authors have attempted to estimate the extent of salt-affected soils in the last 30 years for example Using the FAO/UNESCO soil map of the world (1970-1980) FAO estimated that globally the total area of saline soils was 397 million ha and that of sodic soils 434 million ha

The most common methods for stabilizing black cotton soil are using lime cement kiln dust iron slag cattle waste ash and industrial wastes which cause problems in The expansive soil occurs all over the world Properties of Lime Stabilized Expansive Soil-Quarry Dust Mixes" International Journal of Emerging Trends Salinity and water are inextricably linked This means salinity is affected by climate variability which can tend towards extremes in New South Wales Salinity usually occurs with other natural resource problems such as decreasing soil and water quality erosion and loss of native vegetationGet price
Contaminants in soil can quickly lead to an array of problems so determining possible causes of soil contamination beforehand and learning how to clean contaminated soils is very important What is Soil Contamination? Before you begin to plan and construct your garden it's always wise to have a soil sample analyzed Soil erosion and its impact on our future by Michael Singer Font size Larger Smaller Subscribe to this entry and fertilizes lakes and ultimately the ocean In the case of wind erosion soil becomes dust reducing visibility and becoming a health hazard for those breathing it Accelerated erosion is not one problem it is two reducingGet price
From analysis the soil strength lies below the effective stress acting on the pavement which is equal to 85 16 kN/m It is advisable to replace some quantities of the existing soil and be replaced by quarry dust since quarry dust is a waste product from crushing of stones Soil salinity is a term used to describe the salt content within soil Salt is a naturally occurring mineral within soil and water that affects the growth and vitality of plants Soil salinity can be influenced through several different factors ranging from human influence to environmental causesGet price
Black cotton soil is one of the major soil deposits of India It is highly expansive in nature due to presence of clay minerals especially montmorillonite It expands greatly when comes in contact with water and contracts when the water squeezes out handling and sale of the material Also though the cost of quarry fines is very low at the quarry site the transportation costs discourage the sale of quarry fines beyond a radius of 50-100 miles away from the quarry These limitations account for lack of work done on identifying engineering uses for quarryGet price
Geotechnical characterization of quarry dust and its interaction behavior with soils can lead to a viable/beneficial solution for its large scale utilization and disposal Past studies clearly indicate that the quarry dust has a beneficial effect on different geotechnical properties of soil respirable dust generation from this soil layer during backfilling activities 4 1 3 Watering The Remediation Contractor shall conduct operations and maintain the Site as to minimize the creation and dispersion of respirable dust Clean water provided by the Fugitive Dust Control PlanGet price

Cassava peels are produced as a waste from cassava which are disposed into landfills These become an environmental problem therefore the use of cassava peel ash (CPA) as a soil stabilizer must be encouraged This study investigates the effects of CPA and quarry dust (QD) on the engineering properties of Akwadum soil behavior using compaction test Atterberg limit and California bearing • The Unconfined Compressive Strength (UCS) is increasing with increase in percentage of Quarry Dust • The Differential Free Swell Index (DFSI) is decreasing with increase in percentage of Quarry Dust From the above conclusions drawn it can be inferred that Quarry Dust can be used as stabilizing admixture for expansive soilGet price

Water the area with a sprinkler every few days -- at least once a week -- for an hour or longer using salt-free water to leach the salt out of the top layers of soil You don't need to get the salt completely out of the soil but it must soak deep enough in the soil to fall below the root zone of International Journal of Scientific and Research Publications Volume 3 Issue 12 December 2013 1 ISSN 2250-3153 Use of Quarry Dust to Replace Sand in Concrete – AnGet price
