RISStiffness Behavior of Soil Stabilized with Alkali-Activated Fly Ash from Small to Large Strains
Publisher: American Society of Civil Engineers
Abstract: Alkaline activation of fly ash creates a geopolymeric cement that can replace ordinary portland cement in several applications such as soil improvement, with the advantage of much lower carbon dioxide emissions and reusing ...
Structural Performance of Alkali-Activated Soil Ash versus Soil Cement
Publisher: American Society of Civil Engineers
Abstract: Alkaline activation of fly ash (FA) was used to improve the mechanical performance of a silty sand, considering this new material as a replacement for soil-cement applications, namely, bases and subbases, for transportation ...
Structural Performance of Alkali-Activated Soil Ash versus Soil Cement

Abstract: Alkaline activation of fly ash (FA) was used to improve the mechanical performance of a silty sand, considering this new material as a replacement for soil-cement applications, namely, bases and subbases, for transportation ...
Macromechanism Approach for Vulnerability Assessment of Buildings on Shallow Foundations in Liquefied Soils
Publisher: American Society of Civil Engineers
Abstract: The damage caused by seismic shaking and liquefaction-induced permanent ground deformation has conventionally been assessed as two separate problems often by different engineers. However, the two problems are inherently ...
Voids/Cement Ratio Controlling Tensile Strength of Cement-Treated Soils
Publisher: American Society of Civil Engineers
Abstract: The improvement of locally available soils with cement can provide great advantages, including avoiding the need to borrow volumes of appropriate material and disposing of the local soil in deposits. This research aims to ...
Influence of Cement-Voids Ratio on Stress-Dilatancy Behavior of Artificially Cemented Sand
Publisher: American Society of Civil Engineers
Abstract: The addition of cement is an interesting remediation technique when the project requires improvement of the local soil for the construction of pavement base layers, in slope protection of earth dams and canal linings, as ...
Experimental and Numerical Observations of the Frequency-Domain Method in Bender-Element Testing
Publisher: American Society of Civil Engineers
Abstract: In bender-element (BE) testing, shear-wave velocities are measured using two main methods: time-domain analysis of vibration data from pulse excitation and frequency-domain analysis of vibration from sine-sweep excitation. ...
Fundamental Parameters for the Stiffness and Strength Control of Artificially Cemented Sand
Publisher: American Society of Civil Engineers
Abstract: The treatment of soils with cement is an attractive technique when the project requires improvement of the local soil for the construction of subgrades for rail tracks, as a support layer for shallow foundations and to ...
Time–Frequency Filter for Computation of Surface Acceleration for Liquefiable Sites: Equivalent Linear Stockwell Analysis Method
Publisher: ASCE
Abstract: This paper presents a novel method for performing equivalent linear analysis that allows for a variation of the stiffness and equivalent viscous damping properties throughout the duration of shaking. The ability to change ...
