Effects of low-level silica fume replacement in ASTM C 1260 and ASTM C 227 mortar-bar testing
(2004-12-18)
Replacement of a percentage of cement by supplementary cementing materials (SCM) can control deleterious alkali-silica reaction. Silica fume, a commonly used SCM, and can be used to mitigate alkali-silica reaction (ASR). ...
BIM-based construction waste estimation algorithms for institutional projects
(2018-09-11)
Crucial part of the estimation of construction waste (CW) is a reliable quantification of the amounts of materials needed for building construction. In this research the use of Building Information Modeling (BIM) is proposed ...
Investigation of bond in unreinforced concrete interfaces for partial depth repairs and new construction
(2020-12-04)
This thesis presents an experimental study on the horizontal shear strength of reinforced concrete slabs and beams with unreinforced concrete-to-concrete interfaces. Current design provisions for new construction and repair ...
Behavior of the shear studs in composite beams at elevated temperatures
(2015-12)
In order to improve the fire safety and at the same time to provide more economical design of composite floors in fire, it is important to understand the behavior of these systems under fire exposure. An important step ...
Effects of photocatalysis on concrete surfaces
(2012-05)
Highway air pollution is a significant environmental threat that has staggering implications for human health worldwide. Photocatalytic materials have the potential to reduce air pollution levels near major highways using ...
Durability testing of rapid, cement-based repair materials for transportation structures
(2014-05)
For repairing concrete transportation infrastructure, such as pavements and bridges, much importance is placed on early-age strength gain as this has a major impact on scheduling and opening to traffic. However, the long-term ...
Use of non-steel fiber reinforcement in concrete tunnel lining
(2010-08)
Fiber reinforcement is being widely used in concrete tunnel linings these days. Using fiber reinforcement can save not only cost, but also labor and time spent on construction. However, many owners hesitate to incorporate ...
Experimental investigation of shear transfer between concrete interfaces
(2014-12)
This experimental program was focused on the effect of surface geometry (shear keys) on the transmission of shear forces between concrete cast against a hardened concrete interface. This research was part of a larger study ...
Determination of aggregate shape properties using X-ray tomographic methods and the effect of shape on concrete rheology
(2005)
The shape of aggregate particles can significantly influence certain properties of
concrete, both in its fresh and hardened states. Therefore, there is a need to be able to
completely characterize the shape of aggregate ...
Advancements in concrete material sustainability : supplementary cementitious material development and pollutant interaction
(2013-05)
Calcined clay and fly ash supplementary cementitious materials (SCMs) used in cement based materials were examined for their chemical and mechanical performance, as well as their pollutant interaction. This dissertation ...
