Application of basalt fiber reinforced polymer rebar for prestressed concrete beams
(2022-08)
All steel reinforced concrete infrastructure that is facing a chemical environment and
corrosion will have their service life greatly reduced. With time it will lead to a premature and an
inevitable failure of the steel ...
Factors influencing rates and products in the transformation of carbon tetrachloride by zerovalent iron metal
(2003)
Batch experiments were conducted to study the influence of iron purity and
solution chemistry, i.e., pH and common groundwater species such as HS-, HCO3- and
Mn(II), on the anaerobic degradation of carbon tetrachloride ...
Assessment of Partial Joint Penetration Welds on Bolted End-plate Connections for use in Intermediate Moment Frames
(2016-05-13)
End-plate moment connections are a very common connection type used in the metal building industry today. Bolted end-plate connections are found where a rafter is joined to a column and consist of a steel plate welded to ...
The effects of temperature on compressive strength of rapid setting concrete
(2011)
Rapid setting concrete using Calcium Sulfoaluminate (CSA) cement has been around since the 1960's to meet the need for construction projects with limited time frames. These projects range from quick foundation work to rapid ...
Biological sulfate removal using waste organic substrates in continuous flow-through columns simulating mine water vertical flow bioreactors
(2020)
In mine water passive treatment systems, biological sulfate (SO42-) reduction in vertical flow bioreactors (VFBRs) is often utilized to precipitate trace metals as metal sulfides and to generate alkalinity. Sulfate removal ...
Evaluation of Low Impact Development Stormwater Control Systems for Runoff Peak Flow Reduction
(2021-12-18)
Extreme precipitation events and increasing impervious surfaces, lead to increased runoff, surcharged storm sewer systems and consequent flooding as well as water quality deterioration, costing not only lives and habitat ...
The Use of Recycled Material Backfills to Mitigate the Effects of Expansive Soils on Subterranean Structures
(2016)
The extreme annual weather patterns of the Midwest United States have created a demand for basements as emergency shelters in both residential and commercial structures. However, with the majority of the Midwest experiencing ...
INTERNAL CURING OF CALCIUM SULFOALUMINATE CEMENT CONCRETE USING LIGHTWEIGHT AGGREGATE
(2018-05-12)
Calcium sulfoaluminate (CSA) cement is a very rapid setting, hydraulic cement that releases approximately half as much carbon dioxide during production as conventional portland cement. CSA cement produces concrete with ...
Analysis and Comparison of Cement Selection in Ultra-High-Performance Concrete
(2022)
Ultra-high-performance concrete (UHPC) is a relatively new material that is growing in popularity and usage over recent years. The greatly increased strength and durability of UHPC compared to conventional ACI concrete ...
Modeling and Evaluation of Constituents of Emerging Concern Through Wastewater Treatment Processes
(2016-05-13)
Constituents of emerging concern (CECs) have accumulated in drinking water source supply over the past decades. Although there are currently no established treatment standards, CECs should be of concern to the public and ...
