Black cotton soils and oher expansive soils have typical characteristics of shrinkage and swelling due to moisture movement through them. During rainy season, moisture penetrates into these soils, due to which they swell. Most of the fine grained clays, including black cotton soils have their grains which are more or less in the form of platelets or sheets (just like leafs of a book), and their grains are not round. When moisture enter betwecn the platelets under some hydrostatic pressure, the particles separare out, resulting in increase in th ....etc

Soil stabilization

Soil stabilization a general term for any physical, chemical, biological, or combined method of changing a natural soil to meet an engineering purpose. Improvements include increasing the weight bearing capabilities and performance of in-situ subsoils, sands, and other waste materials in order to strengthen road surfaces.

The prime objective of soil stabilization is to improve the California Bearing Ratio of in-situ soils by 4 to 6 times. The other prime objective of soil stabilization is to improve on-site materials to ....etc

SOIL NAILING


INTRODUCTION
Soil Nailing is a procedure to reinforce and strengthen ground adjacent to an excavation by installing closely spaced steel bars called nails ,as construction proceeds from top down.

It is an effective and economical method of constructing retaining wall for excavation support, support of hill cuts, bridge abutments and high ways.

This process is effectively in cohesive soil, brocken rock, shale or fixed face conditions.

pdf report on digital soil moisture tester

Moisture meters are used to measure the percentage of water in a given substance. This information can be used to determine if the material is ready for use, unexpectedly wet or dry, or otherwise in need of further inspection.

Wood and paper products are very sensitive to their moisture content. Physical properties are strongly affected by moisture content. Dimensioning also changes with moisture content.

Soil moisture sensors measure the volumetric water content in soil. Since the direct gravime ....etc
