(DOI: 10.1016/J.CLAY.2009.01.020) Low rise buildings are particularly vulnerable to ground movements sourced from swelling and shrinking of the expansive clay soils. Geotechnical engineers have long recognized that swelling of expansive clays caused by moisture variation may result in considerable damage to the overlying …
How to improve clay soils Five steps to improving clay soils: Make raised beds to assist drainage and to reduce trampling of the soil; Consider adopting a 'no-dig' regime, especially in raised beds, as these suit clay soils well; Some, but not all, clay soils respond to extra calcium, which causes the soil particles to flocculate (clump together).Where the soil is …
In this research, for stabilizing clayey soil and to achieve higher strength in minimum time period, gypsum (CaSO4.2H2O) is used as one of the soil stabilizing agents.
Gypsum is also helpful where dry clay soils are hard to work or crusty on top. If it's difficult for seedlings to push through this hard crust in the spring, gypsum can help. If you have other types of garden soil, …
Construction Based Drainage Solutions. For those who don't garden at all or do garden and live in areas where rain is fast-hitting and infrequent, a construction-based drainage solution may be best to increase the drainage of your soil. ... Some of the top choices for amending clay soil are: Gypsum; Wood Materials such as mulch or wood chips ...
This study investigated the effect of compaction effort and soaking time on the shear strength properties of fine-grained gypsum-containing soils. The objective was to demonstrate that increasing compaction effort increases soil strength, specifically cohesion and the angle of shear strength, when subjected to soaking in freshwater. …
With a lack of standard lateritic soil for use in road construction, suitable economical and sustainable soil-stabilization techniques are in demand. This study aimed to examine flue gas desulfurization (FGD) gypsum, a by-product of coal power plants, for use in soil–cement stabilization, specifically for ability to strengthen poor high-clay, …

This paper reviews the current beneficial applications of titanium gypsum, analyses the practical applications of titanium gypsum in three fields: extraction of useful material, construction material, and soil amendment, and the impact of these applications on the environment, in order to provide a basis for better understanding and application ...
Nowadays many of the interior and the exterior construction features are mostly governed by gypsum construction or gypsum products. The advancement of gypsum construction in a continuous process is due to its reduced time and cost of construction. With time, gypsum products gain increasing properties like increased fire resistance, …
This page may contain affiliate links. Please read my disclosure for more info.. The compacted, hardpan dirt in my first yard was a despicable pass for soil. The builders scraped off the topsoil when they built the home in 1955, and after the clay subsoil was nice and compacted by construction machinery, they placed sod right on top of it.
This study examines the properties of expansive soil obtained from the city of Muscat in Oman. The expansive soil samples were further treated with gypsum, which was …
Gypsum is a calcium sulfate dihydrate which has many applications as a plaster and concrete additive, as well as a soil fertilizer and conditioner. ... Gypsum Applications: Proper Use of Gypsum for Soil. Written by MasterClass. Last updated: Nov 9, 2021 • 3 min read.
Exactly how much gypsum should be added to clay soil? 2.2 pounds (1 kilogram) per 10 square feet (1 square meter) of land, mixing it into the first 5 inches 10 – 15 cm of topsoil. Add 2 handfuls to each potted plant. This breaks up the clay soil and makes it easier to work with. It also leeches excess aluminum and sodium from the ground, and ...
2.2.. GypsumGypsum used as a stabilizer to improve the some engineering properties of the clays was obtained from the southwest of Sivas (Fig. 1).As reported by Yilmaz and Sendir (2002), Yilmaz, 2007a, Yilmaz, 2007b and Yilmaz and Yuksek, 2008a, Yilmaz and Yuksek, 2008b; microscopic determinations on the gypsum revealed that …
The composition and texture of clay soil also play a role in determining the effectiveness of gypsum. Clay soils are characterized by their fine particles and tendency to become compacted, leading to poor drainage and limited root growth. Gypsum helps to break up the compacted soil particles and improve its structure.
This study examines the properties of Sabkha soil obtained from Sohar city of Oman. The Sabkha soil samples were further treated with Gypsum obtained from waste plasterboards at varying ...
To avoid such damages prior to construction, expansive clays may be stabilized. This paper reports the findings of an experimental investigation to reduce swelling properties …
Using Gypsum for Soil Amendment. Before you use gypsum in your garden, you must carry out a soil test to determine the nutrient condition of the soil. Gypsum reduces the level of salt in the soil which makes it suitable for use in arid and coastal regions. You shouldn't use gypsum in sandy soil as it usually doesn't have …
This study examines the properties of Sabkha soil obtained from Sohar city of Oman. The Sabkha soil samples were further treated with Gypsum obtained from waste plasterboards at varying ...

This study examines the properties of Sabkha soil obtained from Sohar city of Oman. The Sabkha soil samples were further treated with Gypsum obtained from …
Construction developments on naturally occurring Sabkha soils are usually problematic. This study examines the properties of Sabkha soil obtained from Sohar city of Oman. The Sabkha soil samples were further treated with Gypsum obtained from waste plasterboards at varying percentages of 3, 6, 9 and 12 with a view to stabilising the soil.
The expansive soil samples were further treated with gypsum, which was obtained from waste plasterboards, at varying quantities of 3%, 6%, 9% and 12% by mass in an attempt to stabilize the soil. Based on USCS classification system, the expansive soil was identified a poorly clay with high plasticity (CH) with AASHTO classification of A-6.
ABSTRACT. Paper No. 1.05. case study of damage due to expansive soils and rocks in Northern Oman has been studied. Geological and geotechnical investigation revealed …
It is required when the soil available for construction is not appropriate for the intended purpose. In this research, for stabilizing clayey soil and to achieve higher strength in …
Al-Alawi et al. stabilized sabkha soil samples collected from Sohar city, Oman, using gypsum obtained from waste plasterboards. They utilized different …
