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.

Carbonation of cement paste : Understanding, challenges, and opportunities
Branko Šavija,Mladena Luković +1 more
TL;DR: In this article, a review summarises the state of the art regarding the understanding and consequences of carbonation of cement paste and summarises recent efforts regarding active use of carbonations as a tool for manipulating certain properties of cement based materials.

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.

Enhancing the service life of concrete exposed to chloride attack
TL;DR: In this article, the authors proposed a take-down policy to remove access to the work immediately and investigate the claim that the work breaches copyright, if they believe that this document breaches copyright.
Journal ArticleDOI
Feasibility Tests on Concrete with Very-High-Volume Supplementary Cementitious Materials
Keun-Hyeok Yang,Yong-Su Jeon +1 more
TL;DR: Test results showed that as SCM ratio (R SCM) increased, the strength gain ratio at an early age relative to the 28-day strength tended to decrease, whereas that at a long-term age increased up to RSCM of 0.8, beyond which it decreased, and it is recommended that R SCM needs to be restricted to less than 0.85 to obtain a consistent positive influence on the compressive strength and durability of SCM concrete.
Dissertation
Bond and ductility of concrete reinforced with various steel bars surface and ductility conditions
TL;DR: In this article, the impact of steel properties on the bond strength and failure mode of reinforced concrete blocks was investigated and flexural tests were conducted on simply supported RC beams to investigate how reinforcement properties can affect the ductility of RC blocks.
Journal ArticleDOI
Compressive performance of new types of load-bearing horizontal-hole interlocking concrete hollow blocks:
TL;DR: Two loadbearing horizontal-hole interlocking hollow concrete blocks, referred to as H-shaped series and cross-shape series, were developed in this article, including three geometric types.

Effect of early-age freeze-thaw exposure on the mechanical performance of self-compacting repair mortars
Çağlar Yalçınkaya,Halit Yazıcı +1 more
TL;DR: In this article, the effects of fly ash and ground granulated blast furnace slag replacement on early-age freeze-thaw (F-T) resistance of self-compacting repair mortar (SCRM) with and without steel microfibers were investigated.
