Liquefaction Resistance of Gravelly Soils

, 2013
Liquefaction assessments of gravels and soils that contain a large gravel fraction are difficult. Undisturbed (intact) sampling of these soils is problematic and laboratory testing carried out on reconstituted samples or on frozen samples obtained from ...

Seismic response of mitigation of sand liquefaction beneath existing buildings using microbial induced desaturation

Case Studies in Construction Materials
Earthquake-induced liquefaction is a geological disaster that caused extensive damage to buildings, railways, dams. Due to the construction techniques and economic conditions, the subsurface layers of some buildings must be reinforced to resist seismic ...

Role of Fiber Sizing in Interfacial Relaxation, Water Uptake and Fatigue Properties of Acrylic‐Matrix Composites

Polymer Composites, EarlyView.
Characterisation of glass fibre reinforced acrylic with acrylic‐tailored or multi‐compatible sizing agents. ABSTRACT Fiber‐reinforced infusible acrylic monomer resins are of interest as recyclable alternatives to epoxy and other thermoset resin composites, but the novelty of these resins causes published studies on acrylic‐matrix composites to often ...

Ground compaction due to vibrodriving of piles [PDF]

, 1996
Civil engineering construction frequently requires the use of piles to carry structural loads to stronger ground strata or to control lateral ground movements. A variety of techniques are available to install piles into the ground. Of central interest to

Curing Behavior and Structure Reactivity‐Property Relationships in Epoxidized Linseed Oil Thermosets Crosslinked With Biobased Eutectic Hardeners

Journal of Polymer Science, EarlyView.
The curing of epoxidized linseed oil with citric, tartaric, and malic acid–based eutectic hardeners is compared to reveal how acid functionality, hydroxyl content, and molecular geometry govern activation energy, reaction rates, and network rigidity.

Experimental assessment of the liquefaction resistance of calcareous biogenous sands [PDF]

, 2012
Liquefaction is a phenomenon in which soils, typically sands, suddenly loose a substantial amount of their shear strength and stiffness, this often triggered by large-magnitude earthquakes.
