The unconfined compression test ...

 — The crushed glass was then introduced and mixed into the clay in five distinct percentages of 0, 5, 10, 15 and 20% with respect to the dry weight of clay. It is worthy of note that the oven-dried soil was crushed utilising a mechanised soil crusher to disintegrate the lumps of clay, allowing for the glass to be uniformly distributed in the clay.

 — Investigate the effect of using traditional additives cement, lime, FA, and RHA (with and without lime), and nano-cementitious material (RoadCem) on the …

Lime-stabilized clay and Portland cement-stabilized sand are two examples. The chemical stabilizers, normally added at a 2 to 10% rate, increase soil internal cohesion via chemical bonding. Chemically-stabilized soils, which are stiffer and stronger than the unreinforced soils, also exhibit tensile cracking as a major mode of failure ...

 — Rapid urbanization has resulted in a massive number of infrastructure projects throughout the country. Steel consumption has skyrocketed as a result of this urbanization and industrialization. India is currently the one of the world's largest steel producers. An integrated steel plant produces 2–4 tonnes of slag for every tonne of steel …

 — The current study analyzed a total of 28 flexible pavement sections for evaluating influence of cementitious stabilization of soil on pavement distresses under different climate, traffic, and reliability level conditions. A total of three stabilizers, namely, 3% lime, 15% class C fly ash (CFA) and 15% cement kiln dust (CKD) were selected. A …

 — Cement-stabilized specimens with 10% crushed stone waste showed a significant increase in UCS. The CBR and UCS of unsoaked specimens were higher than for soaked specimens at different crushed stone waste and cement contents. ... Lee FH (2019b) Measure for reducing the tensile stress in cement-treated soil layer in deep …
