Expansive soils are produced from the break down of basic igneous rocks where seasonal variation of weather is extreme. In India, these soils are normally derived from the weathering of basalt rocks. Also, these soil deposits are derived from various other types of rocks including very old sedimentary depositsin the present research, an attempt has been made to study the stabilization of the local soils high and low expansive having low bearing strength from two different parts of Bhopal by mixing independently with dolochar and fly ash plentily available in Bhopal in the proportions from 5 up to 30 by dry weight of the mixture with increment of 5 with and without lime The experimental programme conducted in this study is comprised of index tests, compaction tests, shear tests, unconfined compressive strength tests, CBR tests and consolidation tests in conformity with approved standards on soil alone and also on stabilised soils to evaluate their individual swelling, compaction, strength, compressibility and drainage characteristics. With addition of fly ash or dolochar, the L.L. and P.I. of soils gradually decreases with the increase of fly ash or dolochar contents. Maximum decrease is observed at 30 fly ash or 30 dolochar content Addition of fly ash or dolochar decreases the free swell index FSI of soil, maximum decrease being observed at fly ash or dolochar content of 30 . Addition of lime to the above mixtures, reduces FSI further. The FSI of soil 1 with 30 fly ash or dolochar content is reduced by 100 and 85 for soil fly ash and soil dolochar mixture respectively at 4 lime content. CBR of soil fly ash or soil dolochar increases with the increase of fly ash or dolochar content. The maximum increase being observed at 30 fly ash or dolochar content. At 30 fly ash content, the 4 days soaked CBR of soil 1 and soil 2 increase by 126 and 117 respectively, whereas, the 4 days soaked CBR of soil 1 and soil 2 at 30 dolochar content increase by 154 and 163 respectively.

Smartsense structural system is the leading wafflemat foundation forming system for the single, multi family residential and commercial structures constructed on an expansive, rocky or compressible soils. Smartsense provide cost saving services without any structural failure.

Waffle Slab Construction is one of the leading construction services in the US these days. A waffle slab construction is very easy and quick when constructed under good supervision and care. Waffle Slab takes very less time than any other foundation systems on expansive soil. A waffle slab construction requires very less amount of concrete and steel which results in less carbon emission which makes it a nature-friendly foundation.

[smartsensesystems]

A Waffle Slab Foundation is one of the stiffest and versatile foundation system. It is an environmental friendly foundation as it uses very less amount of concrete, steel and doesn't require any soil preparation which results in less carbon emission and soil erosion. One of the major advantage of this type of foundation system is that there are void spaces between the soil and the coil caps which prevents any damage to the foundation due to the vertical movement of the soil.

The potential problem A non-expansive soil cap on top of expansive soil may not always stop expansion of the underlying expansive soil, or the resulting damaging effects of on the foundations and structures built on top of the soil cap. However, if the foundations built on top of the soil cap are designed to be rigid en

This work presented to see the efficiency of nano technology used in terms of chemical named as Terrasil which acts as a modifier and improves the engineering properties of black cotton soil. In India, we see about 51.8 million hectors of land area is covered with black cotton soil which is an expansive soil. It is seen that black cotton soil is very hard when it is dry, and it loses its strength completely when it is wet. Expansive soils are problematic soils worldwide and create problems while constructing structures on it. To improve their properties various methods are adopted. These soils are removed completely or mixed with better quality material or mixed with various additives. This chemical called terrasil is tested by conducting various tests like Proctor test, free swelling test, etc. Soil samples are treated with different percentage of Terrasil 0.9 , 1.1 , and 1.3 . Terrasil gives improved results up to 40 increasing compressive strength of soil. It reduces the swelling property of soil from 60 to 42 .

Effect of Garment Wastes on Swell-Consolidation Characteristics of Expansive Soil-Iris Publishers

Authored by Md Shariful Islam* 

Expansive soil is available throughout the world. In semi-arid country like Bangladesh, this type of soil is found almost everywhere. Expansive soil is considered to be problematic due to its high swelling potential. This type of soil exhibits large volumetric changes when its water content changes. This is highly detrimental to civil engineering infrastructures. This experimental study investigates the effect of the inclusion of garment wastes into expansive soil on its swell-consolidation characteristics. Due to the rapid growth of garment industries in Bangladesh, a huge amount of garment wastes is produced every year. The use of such waste materials to improve the swell-consolidation characteristics would be significant. To determine the effect of the inclusion of garment wastes into expansive soil, one dimensional swell-consolidation tests were conducted in the laboratory. Two types of expansive soil collected from Godagari, Rajshahi and Gazipur, Dhaka were used in the study. Various proportion of garment wastes by weight of soil (0.5%, 1%, and 2%) were mixed with the expansive soil and the samples were subjected to one dimensional swell-consolidation tests. The test results show that the inclusion of garment wastes has significant effect on the swell-consolidation characteristics of expansive soil. It is noticed that the inclusion of garment wastes decreases the heave, swelling potentials and vertical swelling pressures of expansive soil.

Don't Let Expansive Soils Ruin Your Landscape

Don’t Let Expansive Soils Ruin Your Landscape

Expansive soils shrink and swell in response to soil moisture levels. Moving soil exerts tremendous pressure on paving, footings, and foundations.

How To Identify Expansive Soils

Landscape architects can design and build on sites with expansive soil if they get the right information and engineering guidance.

First, identify if the soil on your client’s site is expansive. There are a couple of…
