This paper represents the results of a laboratory study undertaken to investigate the effect of marble dust powder on the index properties of black-cotton soil. The black-cotton soil features a poor supporting capacity and enormous change in volume on variations of moisture content. Such expansive soils may need to be improved to make them suitable for …
• Due to salinity, plants are not able to draw as much water from the soil. When the soil salinity levels are high enough, the water in the roots is pulled back into the soil. The plants are not able to take in enough water to grow. • The major source of salinity problems is usually irrigation water. • Salt-affected soils can be corrected by:
Salinization and Nutrient Loss . Soil salinization is the concentration of salts in the surface or near surface of soils. Human induced salinization is a major problem in drylands and is often associated with large-scale irrigation. When drylands are irrigated, the water evaporates quickly, leaving behind previously dissolved salts. These salts ...

This book takes an interdisciplinary approach to the research into the classification and compositions of various types of fly ash, such as bottom ash and boiler slag, special classes of fly ash, and their sources around the globe.
The soil pH is an effective way to measure the H + and OH − concentrations in a soil solution (McKenzie et al., 2004).It is observed that the pH value of the soil amended with marble dust contents increases up to 15%, and decreases thereafter up to 40%.
Sustainable use of marble slurry in concrete. May 01 2015 0183 32 Six concrete mixes containing marble slurry up to 25 in place of Portland cement were prepared and evaluated for strength permeability porosity morphology resistance to chloride migration carbonation and corrosion Optimal replacement level of Portland cement by marble slurry was found at 10...
The minerals found in some playas contain hazardous metals that could be harmful to humans if dust from the playa were to blow into populated areas during a dust storm. Additionally, salt from playas can affect the salinity of soil in nearby agricultural areas, adversely affecting agricultural production.
Compared to natural soils, the use of 70% CS and 30% FA was estimated to save about 40% of the production costs.Civil engineering construction projects, particularly highway projects, built on problematic soils, including soft soils, expansive soils, and other soil types, require some form of soil stabilization to improve the subsoil properties.
The Dust Bowl was an area in the Midwest that suffered from drought during the 1930s and the Great Depression. The soil became so dry that it turned to dust. Farmers could no longer grow crops as the land turned into a desert. Areas of Kansas, Colorado, Oklahoma, Texas, and New Mexico were all part of the Dust Bowl. Did Minnesota have dust storms?
properties of Collapsible soil as a new stabilizing technique. A series of experimental tests are carried for samples of collapsing soil with and without stabilization using marble dust for dry and soaked conditions. The collapsible soil was mixed with marble dust at different contents of (0, 10, 20, 30%,40% and50%).

Shallow stabilization involves scarifying the soil to the required depth and lime in powder or slurry form is spread and mixed with the soil using a rotovator. The use of lime as deep stabilizer has been mainly restricted to improve the engineering behaviour of soft clays Deep stabilization using lime can be divided in three main groups: lime ...
The Roman author Varro, also of the first century C.E., offered a classification distinguishing rock, marble, rubble, sand, loam, clay, red ochre, dust, chalk, ash, and carbuncle . Soil knowledge acquired special importance when and where population pressure and land shortage impinged, as in the ancient Mediterranean.
marble dust on the hardened properties of concrete mix will be discussed in two segments. The first segment will discuss the impact of concrete by changing the soil from the marble dust and second segment deals with changing the cement from the marble dust. Keywords: Waste, Marble Dust, Concrete, Environment protection. 1. INTRODUCTION
Soil pH increased and extractable metals decreased in lower soil horizons. Plant response in the field study was disappointing. Use of LKD + BS showed lush growth after an initial period of no growth. Response to in situ amendments may vary across large-scale restoration efforts : LKD only (LKD): Cd: 100% of 7.5 mg/kg
DMS – DS 100: DMS-DS® 100 is specially designed for dust control and soil stabilization of haul roads, industrial roads, and well-compacted surfaces to improve its overall strength and road materials agglutination. It can also be used on coal stockpiles/trains/trucks to prevent the creation of wind-borne coal dust, thus protecting the ...
The use of waste materials in soil stabilization is very important in terms of recycling of waste materials and reducing environmental pollution. The aim of this study is to investigate the effective use of waste marble dust, WMD in deep soil mixing, which is one of the ground improvement techniques used for problematic soils. In this study, loose sand was …

To investigate the effects of dust particles on physiological and yield characteristics of grapevine cv. Bidaneh Safid, a field experiment in randomized complete block design (RCBD) was conducted on 40 plants at the Malayer Grape Research Station, Iran, during 2015-2017. The treatments comprised of: 1) artificial dust (4.3 micron, on average), 2) washing vine by well …
Additionally, the mining process generates marble dust, which can deteriorate soil quality, cause air pollution that affects the physiology of plants, and contaminate water sources, making them ...
The soil is sensitive to wetting, warranting its stabilization. Waste marble dust (WMD) in varying percentages was used as an admixture. The study's optimization process showed that geotechnical parameters of collapsible soil improved substantially by adding waste marble dust.
Gardeners use lime to raise the pH level of acidic soil, which can help certain plants extract nutrients from the soil. Garden lime is processed from marble. The marble is heated in a kiln, which removes the carbon dioxide from the stone, producing a form of …
experimental study of stabilization of expansive soil using the mixture of marble dust, rice husk ash and cement for sub-grade road construction: a case study of woldia town September 2021
Abstract The large-scale utilization of waste materials is possible due to their comprehensive geotechnical and mineralogical characterization and their interaction behaviour with soil. No significant attempt has been made to use marble dust, a waste product resulting from the quarrying and crushing of marble, to determine its potential utilization as a geo-material.
The Nile Delta's Disappearing Farmland. During the time of the pharaohs, the fertile soils along the Nile River likely supported a civilization of roughly 3 million people. Now there are 30 times that number of people living in Egypt, with 95 percent of them clustered in towns and cities in the Nile's floodplain.
Describe one method for remediating soil affected by acid deposition. - Add crushed limestone/ lime/ marble dust/ bone meal/ crushed egg shells or oyster shells. Describe TWO ways that climate change can degrade soil. - Increased global temperatures and decreased precipitation cause desertification.

The results revealed that marble dust can be utilized effectively to improve soil plasticity and to control the swell behaviour. It is interesting to note that marble dust accelerates the strength of soil at early curing periods and that the optimum improvement in the strength behaviour of the soil is observed with a marble dust content of 20%.

The high levels of chlorine in the rain water correlated to those in arable fields in the west of the country and indicated the transference of contaminants on dust by the prevailing wind. The increased soil salinity may exacerbate boron (metalloid) phytotoxicity due to higher mobility under alkaline conditions (Princi et al., 2016).
Marble dust was mixed with the expansive soil by different proportions (5%, 10%, 15%, 20%, and 25%) by the dry weight of the soil.
