Analysis of strength development in cement-stabilized silty clay from microstructural considerations

This paper presents details of a study that deals with determination of engineering properties, identification of phases of major hydration products, and microstructural characteristics of a zinc-c...

Engineering properties and microstructural characteristics of cement-stabilized zinc-contaminated kaolin

This report presents information on the characterization of cementitiously stabilized layers and the properties that influence pavement performance. It also contains recommended performance-related procedures for characterizing these layers and performance-prediction models for incorporation into the mechanistic–empirical pavement analysis methods. Individual chapters highlight pavement distresses of hot-mix asphalt pavements and concrete pavements, laboratory tests and model development, and model calibration. The material contained in the report will be of immediate interest to state materials, pavement, and construction engineers and others involved in the different aspects of pavement design and construction.

Characterization of Cementitiously Stabilized Layers for Use in Pavement Design and Analysis

This paper examines the strength and modulus of marine clay-cement mixes with high cement content. Although similar studies have been reported, many of these studies were conducted using soil-cement and water-cement ratios which are more applicable to deep cement mixing than jet grouting. The objective of this study is to investigate how the strength and modulus of cement-treated Singapore marine clay vary with cement and water contents at a range of cement contents, which is more representative of that used in jet grouting. To facilitate parametric studies that are relevant to jet grouting operations, a working range of the constituents was proposed for Singapore marine clay based on the liquid and bleeding limits of the soil-cement mixes. Comparison with data from some previous jet grouting studies and projects indicates that the liquid and bleeding limits can encompass most, if not all, of the parameter range normally used in jet grouting operations. The results of unconfined compression tests on cemen...
