Thank you for downloading properties of concrete. As you may know, people have look hundreds times for their chosen readings like this properties of concrete, but end up in malicious downloads. Rather than reading a good book with a cup of coffee in the afternoon, instead they juggled with some malicious virus inside their computer. properties of concrete is available in our digital library an online access to it is set as public so you can download it instantly. Our digital library hosts in multiple locations, allowing you to get the most less latency time to download any of our books like this one. Merely said, the properties of concrete is universally compatible with any devices to read.read more

Properties of Concrete at Elevated Temperatures
TL;DR: In this paper, the thermal, mechanical, deformation, and spalling properties of concrete are discussed, and various properties that influence fire resistance performance, together with the role of these properties on fire resistance, are discussed.
Journal ArticleDOI
Development of an eco-friendly Ultra-High Performance Concrete (UHPC) with efficient cement and mineral admixtures uses
TL;DR: In this paper, a modified Andreasen & Andersen particle packing model is used to achieve a densely compacted cementitious matrix, and the results show that the influence of FA, ground granulated blast-furnace slag (GGBS) and limestone powder (LP) on the early hydration kinetics of UHPC is very similar during the initial five days, while the hydration rate of the blends with GGBS is mostly accelerated afterwards.

High-performance fiber-reinforced concrete: a review
TL;DR: In this article, the authors present a comprehensive review of the mechanism of crack formation and propagation, compressive strength, modulus of elasticity, stress-strain behavior, tensile strength (TS), flexural strength, drying shrinkage, creep, electrical resistance, and chloride migration resistance of high performance fiber reinforced concrete.
Journal ArticleDOI
Investigation of coal bottom ash and fly ash in concrete as replacement for sand and cement
TL;DR: In this paper, the authors investigated the use of coal ash in concrete to replace sand with bottom ash waste and cement with fly ash and concluded that those experimental concrete mixes can be used in several structures (foundations, subbases, pavements, etc.) which will minimize the cost, energy and environmental problems to a great extent.
