1996年12月1日 · The swell-shrinkage behavior of expansive clays was investigated in four soils of different plasticity cyclic swelling. To simulate drying temperatures typical of site conditions, two shrinkage schemes were adopted, partial and full shrinkage.

Fine-grained, clay-rich soils can absorb large quantities of water after rainfall, becoming sticky and heavy. Conversely, they can also become very hard when dry, resulting in shrinking and cracking of the ground. This hardening and softening is known as ‘shrink–swell’ behaviour.

Expansive clay, also called expansive soil, is a clay soil prone to large volume changes (swelling and shrinking) directly related to changes in water content. [1] ... (XRD) test that can identify specific clay minerals, such as montmorillonite, which would indicate shrink-swell …

2013年9月17日 · In the present research, a comprehensive laboratory investigation was undertaken to study the volume change related swell–shrinkage behaviors of five different types of expansive clayey soils sampled from various regions in Texas, USA.

2016年1月1日 · Expansive soils contain appreciable amounts of swelling clay minerals. Expansive soils, known by various nomenclatures worldwide, are a unique group of soils that expand when wetted and shrink when dried. These include predominantly Vertisols and vertic intergrades in US soil taxonomy (Soil Survey Staff, 2006).

Swelling, or soil expansion, can cause the ground to heave causing damage to buildings, roads, and other structures. Soil shrinkage can cause structure settlement or subsidence. If you think your property is underlain by clay soils that are capable of shrinking and expanding, contact your insurance company for more information.

2023年5月3日 · This study investigated the effects of recycled glass (RG) content and particle size on the mechanical and shrink-swell behaviour of clay-recycled glass mixtures. In the current study, a type of RG with particle sizes up to 2.36 mm was mixed with expansive clay at …

The shrink–swell capacity of soils refers to the extent certain clay minerals will expand when wet and retract when dry. Soil with a high shrink–swell capacity is problematic and is known as shrink–swell soil, or expansive soil. [1]

2012年1月1日 · Expansive soils are soils that experience significant volume change associated with changes in water contents. These volume changes can either in the form of swell or in the form...

2025年2月15日 · Expanding on the challenges of expansive soils to civil infrastructure, this research delves into the synergistic application of microbially induced calcium carbonate precipitation (MICP) through bio-stimulation and natural fiber reinforcement to mitigate soil swell-shrink behavior and enhance soil strength. This research diverges from traditional methods by addressing their economic and ...
