Proportioning manufactured sand in flowable concrete
(2020-12)
Manufactured sand has started to be used in concrete due to its availability and low cost. However, it has different shape properties, gradations, and mineralogy in comparison to the natural sand, and these differences can ...
Applying satellite remote sensing, unmanned systems, and models for water quality analysis
(2022-07)
Transport of soils and sediment by runoff diminish the surface water quality of lakes/reservoirs and shrink reservoir capacity. Nutrients move with transported soil and sediment due to soil erosion by floods and high wind. ...
Variation of soil suction and application of remote sensing in evaluating unsaturated soil behavior within vadose zone
(2023-05)
Moisture movement in pavements and road embankments is receiving more attention in pavement and geotechnical engineering. Water from rainfall is the primary source of moisture in soils. Following a rainstorm event, large ...
Novel methods of quantifying curing influence and freeze thaw cycles in the field
(2022-05)
This work developed a flexible resistivity sensor that provides a novel perspective to develop a deep understanding of two important problems for concrete, i.e. curing influence on concrete hydration and freeze-thaw cycles ...
Reliability and sensitivity analysis of civil and marine structures using machine-learning-assisted simulation
(2022-12)
Civil and marine structures are subjected to various deterioration mechanisms due to aggressive environmental effects or mechanical loads. In order to maintain an acceptable performance level of these structures, previous ...
Experimental and numerical analyses on the behavior of civil and marine steel structures
(2022-12)
Bolts and welds in combination occur most commonly during the construction phase of a building when the design load changes, when there are unforeseen difficulties in make-up or matching of bolt holes, or in retrofit of ...
Implementation of structural monitoring to assess the performance and serviceability of concrete and steel girder bridges
(2023-05)
This research focuses on bridges and the development of structural monitoring systems used for both concrete and steel bridges. Parts of two bridges were built with a combination of sensors attached to a data acquisition ...
Investigation of ion diffusion in cementitious materials with x-ray imaging techniques
(2020-07)
Concrete is susceptible to the migration of highly deleterious ions. The external penetration of ions into cementitious materials is the primary factor influencing the longterm durability of concrete structures. There are ...
Multimodal approach to improve fire safety on construction sites
(2022-12)
Fire risk on construction sites is a threat to property and construction workers’ safety. Fire safety on construction sites has been rarely studied because fire accidents have a lower occurrence compared to Construction’s ...
Predicting fly ash performance in concrete from particle characteristics
(2020-05)
While fly ash is widely used as supplementary cementitious material (SCM) in concrete, the demands of fly ash have been increased in producing high-performance concrete. Fly ash can contribute to the strength gain and ...
