RISBearing Capacity of Circular Footing Resting on Fiber-Reinforced Pond Ash Overlying Soft Clay
Publisher: ASCE
Abstract: Model footing tests were conducted of a circular footing resting on a randomly distributed fiber-reinforced pond ash (RDFP) layer overlying soft clay. The effect of varying the thickness of the pond ash layer over soft ...
Closely Spaced Footings on Geogrid-Reinforced Sand
Publisher: American Society of Civil Engineers
Abstract: The results discussed in this paper are based on a total of 74 tests performed on closely spaced strip and square footings on geogrid-reinforced sand. The study was carried out to evaluate the effect of spacing between the ...
Load-Settlement Behavior of Concrete Debris Pile in Fly Ash Fill
Publisher: ASCE
Abstract: This study addresses the problem of disposal and effective reuse of waste material, fly ash, and construction concrete debris in order to find an optimized solution for their bulk disposal. Providing granular pile (stone ...
Biofilm Characterization and Establishing Microbial-Induced Calcite Precipitation Treatment Process for Ganga River Sand by Using the Sand Column Method
Publisher: ASCE
Abstract: Biocementation using the microbial-induced calcite precipitation (MICP) technique is an environmentally friendly method that imitates the natural cementation phenomenon to improve the behavior of soils. Urea hydrolysis ...
Engineering and Leaching Behavior of Lime-Treated Fly Ash Amended with Montmorillonite Nanoclay
Publisher: American Society of Civil Engineers
Abstract: Researchers have explored the utilization of nanoparticles to improve the properties of soils for various geotechnical construction applications. However, the potential of nanoparticles and their mechanisms of action in ...
Influence of Microbially Induced Calcite Precipitation Technique on Mitigating Rainfall-Induced Surface Erosion of the Ganga River Sand
Publisher: American Society of Civil Engineers
Abstract: Microbially induced calcite precipitation (MICP) is an emerging field of microbial geotechnology for surface erosion remediation. Conventionally, Sporosarcian pasteurii bacteria are used mostly for MICP treatment to enhance ...
Enhancing Mechanical Characteristics of Fly Ash and Fly Ash–Stone Dust Using Geopolymerization Technique
Publisher: American Society of Civil Engineers
Abstract: Geopolymer, an inorganic aluminosilicate polymer, is considered a sustainable construction material. However, a notable research gap still persists in minimizing the use of alkali activators and calcium-based additives by ...
Influence of Fly Ash, Lime, and Polyester Fibers on Compaction and Strength Properties of Expansive Soil
Publisher: American Society of Civil Engineers
Abstract: An experimental program was undertaken to study the effects of polyester fiber inclusions and lime stabilization on the geotechnical characteristics of fly ash-soil mixtures. An Indian fly ash was mixed with expansive soil ...
Use of Sequencing Batch Reactor for Biological Denitrification of High Nitrate-Containing Water
Publisher: American Society of Civil Engineers
Abstract: The efficiency of a sequencing batch reactor in denitrification of drinking water with relatively high nitrate concentrations (40–250 mg/L as N) was evaluated. Ethanol at a COD/N of 2.00 was found sufficient to reduce ...
