Ecology block with rebar loop on top for use with heavy equipment. An ecology block, also known as an eco-block or ecoblock, is a type of recycled concrete block used to make retaining walls. Ecology blocks are manufactured using concrete left over from other construction processes.
MSE walls stabilize unstable slopes and retain the soil on steep slopes and under crest loads. The wall face is often of precast, segmental blocks, panels or geocells that can tolerate some differential movement. The walls are infilled with granular soil, with or without reinforcement, while retaining the backfill soil.
The process simultaneously breaks up the soil without removing it, injects a binder at low pressure and thoroughly mixes the binder with the soil to form a reinforced block of soil after treatment. [3] The soil to be improved is mixed mechanically in-situ either with a binder in a slurry form (wet method) or with a dry binder (dry method). [2]
A basement wall is thus one kind of retaining wall; however, the term usually refers to a cantilever retaining wall, which is a freestanding structure without lateral support at its top. [2] These are cantilevered from a footing and rise above the grade on one side to retain a higher level grade on the opposite side.
The curve obtained from the graph of water content against the log of blows while determining the liquid limit is almost straight and is known as the flow curve. The equation for flow curve is: W = - I f Log N + C Where 'I f is the slope of flow curve and is termed as "Flow Index" [9]
A cement bond log documents the evaluation of the integrity of cement work performed on an oil well. [1] In the process of drilling and completing a well, cement is injected through the wellbore and rises up the annulus between the steel casing and the formation .
The method is an extension of the Newmark's direct integration method originally proposed by Nathan M. Newmark in 1943. It was applied to the sliding block problem in a lecture delivered by him in 1965 in the British Geotechnical Association's 5th Rankine Lecture in London and published later in the Association's scientific journal Geotechnique.

Typically in the form of a horizontal wire or rod, or a helical anchor, a tieback is commonly used along with other retaining systems (e.g. soldier piles, sheet piles, secant and tangent walls) to provide additional stability to cantilevered retaining walls. [1]
