This paper describes results of NIST's experimental program that focuses on effects of elevated temperature exposure on residual mechanical properties of HPC. Residual mechanical properties were measured by heating the mm x mm cylinders to steady state thermal conditions at a target temperature, and loading them to failure after the Cited by: With cooling tests on polypropylene fiber reinforced concrete and plain concrete that were initially subjected to different heating temperatures, the change of mechanical properties including mass loss, uniaxial compressive strength and microstructure were analyzed. The results show that the compressive strength of concrete tend to decrease with an increase in by: 1.

Shavers, Under Secretary for Technology National Institute of Standards and Technology Raymond G. Kammer. This report describes results of NIST's experimental program that focuses on effects of elevated temperature exposure on mechanical properties of hing strength concrete (HSC).
Mechanical properties were measured by heating, with and without preload, the mm x mm HSC cylinders to steady state thermal conditions at a target temperature Author: Long T. Phan, Nicholas J.
Carino. Many contributions even demonstrate that polypropylene fibres have negative effect on the residual mechanical properties of polypropylene fibre reinforced concrete (PPFRC) after high-temperature exposure as they significantly decrease the residual compressive strength, elastic modulus and tensile strength as well as they increase peak strain.Cited by: Get this from a library.
Mechanical properties of high performance concrete after exposure to elevated temperatures. [J R Lawson; Long T Phan; Frank Davis; National Institute of. The macro-mechanical properties of ECC with high-volume fly ash after sub-elevated temperature exposures of 50 °C, °C and °C were investigated in this paper.
The compressive strength of ECC remained almost unchanged after temperature exposures of 50 °C and °C, but declined after temperature exposure at ° by: The mechanical properties of concrete decreased significantly after the exposure to over °C as a result of chemical and physical damages induced by elevated temperatures (Karataş et al.
Although concrete is a noncombustible material, high temperatures such as those experienced during a fire have a negative effect on the mechanical properties. This paper studies the effect of elevated temperatures on the mechanical properties of limestone, quartzite and granite concrete.
Samples from three different concrete mixes with limestone, quartzite and granite coarse aggregates Cited by: The majority of research in this field to date has concentrated on the mechanical properties of concrete such as compressive strength at elevated temperatures.
In order to fully develop accurate computational analyses of the performance of concrete in fire, the long-term deformation of concrete known as creep at elevated temperature must be.
However, relatively little attention has been directed at studying the performance of concrete made with RCA at elevated temperatures.
This is despite the fact that coarse aggregates play an important role in the behavior of concrete under fire exposure. Arioz  has studied the effect of elevated temperatures on concrete and found that the concrete specimens exhibit dramatic reductions in both weight loss and mechanical strength after exposure.
High-strength steels (HSS) are produced using special chemical composition or/and manufacturing processes. Both aspects affect their mechanical properties at elevated temperatures and after cooling down, and particularly the residual strength and the ductility of the structural members.
As HSS equates the design of lighter structural elements, higher temperatures are developed internally Cited by: 7. In this paper, the effect of elevated temperatures on the mechanical and basic properties of two different newly-designed high-strength concretes is studied.
The studied materials were prepared from Portland cement, steel fibers, reactive finely milled quartz powder and quartz sand, silica fume, plasticizer, and with a relatively low water/cement ratio of Author: Lenka Scheinherrová, Monika Čáchová, Michaela Petříková, Lukáš Fiala, Eva Vejmelková, Stefania Grzes.
The mechanical properties that are of primary interest in fire resistance design are compressive strength, tensile strength, elastic modulus, and stress-strain response in compression.
Mechanical properties of concrete at elevated temperatures have been studied extensively in the literature in comparison to thermal properties [ 12, 39, 50 Cited by: By using an electrohydraulic servo fatigue testing machine, fatigue tests were performed on C60 high strength concrete (HSC) under low cyclic compressive loading after undergoing normal temperature, °C, °C, °C, and °C.
