RISSoil Stabilization by Calcium Carbide Residue and Fly Ash
Publisher: American Society of Civil Engineers
Abstract: Calcium carbide residue (CCR) and fly ash (FA) are both waste products from acetylene gas factories and power plants, respectively. The mixture of CCR and FA produces a cementitious material because CCR contains a lot of
Steady-State Groundwater in Mechanical Stabilized Earth Walls of Various Dimensions with Geocomposite Back Drain Installation
Publisher: ASCE
Abstract: Recently, considerable risks to the internal instability of mechanically stabilized earth (MSE) walls have been encountered from the inadequate drainage capacity of some backfill under extremely heavy rainfall. Due to its ...
Influence of Wet-Dry Cycles on Compressive Strength of Calcium Carbide Residue–Fly Ash Stabilized Clay
Publisher: American Society of Civil Engineers
Abstract: This article studies the durability of the calcium carbide residue (CCR) and fly ash (FA) stabilized silty clay against wetting and drying cycles to ascertain its performance in pavement applications. The durability test ...
Recycled Concrete Aggregate Modified with Polyvinyl Alcohol and Fly Ash for Concrete Pavement Applications
Publisher: American Society of Civil Engineers
Abstract: Recycled concrete aggregate (RCA) is traditionally limited to nonstructural applications. Although the crushing process results in weak mortar particles and surface cracks throughout the RCA, RCA concrete can be employed ...
Mechanical Properties of Fly Ash–Asphalt Emulsion Geopolymer Stabilized Crushed Rock for Sustainable Pavement Base
Publisher: ASCE
Abstract: Research on the usage of industrial by-products to improve mechanical properties of low-quality materials in infrastructure applications is of global interest. Two industrial by-products, namely, fly ash (FA) and asphalt ...
Laboratory Approach for Faster Determination of the Loading-Collapse Yield Curve of Compacted Soils
Publisher: American Society of Civil Engineers
Abstract: A shift in the preconsolidation pressure or yield limit with suction, referred to as the loading-collapse (LC) yield curve, is an important feature of elastoplastic models of unsaturated soils. The LC curve is typically ...
Influence Factors Involving Rainfall-Induced Shallow Slope Failure: Numerical Study
Publisher: American Society of Civil Engineers
Abstract: Assessment of rainfall-induced shallow slope failures is important for reducing damage to infrastructures as well as for the safety of people living close to hazardous areas. The rainfall intensity-duration thresholds for ...
Water-Void to Cement Ratio Identity of Lightweight Cellular-Cemented Material
Publisher: American Society of Civil Engineers
Abstract: Lightweight cellular cemented clays have wide range of applications in the infrastructure rehabilitation and in the construction of new facilities. Since the inception of this method, the developments in the plant and ...
