Soil-Cement Frequently Asked Questions Because there is no noticeable color change, how can I tell how deep my roadway materials were treated with cement? Basically, when cement is added to the soil material, the resultant mixture experiences an increase in pH—usually into the moderate to strongly alkaline range from 8.0 to 9.0.
soil-cement shall form a 2:1 (H:V) slope, or flatter, in order to facilitate replacement of a repair wedge. A soil-cement scour cap 2 feet thick or less shall be removed by the concrete saw method. For this method, the exposed cut surface may be vertical. ii. For soil-cement removal 6 feet deep or less, the replacement wedge shall be anchored to

Cement-Modified Soil (CMS) and Cement-Stabilized Subgrade (CSS) soil are two distinct types of Soil-Cement applications. Both CMS and CSS improve the physical properties of native in situ soils, and both help extend the life of a pavement or structure by providing uniform support via a durable, stable, and typically non-expansive subgrade or foundation.

However, the cement acts as a binder between the soil particles and, like cement-treated base (CTB), the SC gains strength and durability as the cement hydrates. Cement-Modified Soil (CMS) A compacted mixture of pulverized in situ soil, water, and small proportions of portland or blended cement that results in an unbound or slightly bound material.
Cement-modified soil (CMS) is a term used to describe native soils and/or manufactured aggregates that have been treated with a relatively small proportion of portland cement. …
Compacted and finished soil-cement contains sufficient moisture for adequate cement hydration. A moisture-retaining cover is placed over the soil-cement soon after completion to retain this moisture and permit the cement to hydrate. Most soil-cement is cured with bituminous material, but other mate rials (see page 57) are satisfactory. 4 5
