“…Self-compacting concrete (SCC) is now widely developed and is a new type of concrete designed to bring many benefits to the properties of structural concrete [1][2][3][4][5]. What differentiates SCC from conventional concrete is the ability to be compacted by its own weight without the need for vibration [6][7][8].…”

“…The size range that attracts significant attention is below 100 nm (Chang, 2007). Researchers have already perfoemed studies on the application of materials in nano scale and/or pozzolanic materials in self-compacting mortar or concrete with scope to improve mechanical and physical properties (Barbhuiya, 2011;Hou et al, 2012;Madandoust et al, 2015;Mohseni et al, 2015a;2015b;Yang et al, 2015). However, there is limited research concentrated on the cement-based materials properties containing nano-Al 2 O 3 (Nazari and Riahi, 2011b;Li et al, 2006;Oltulu and Sahin, 2013;Barbhuiya et al, 2014).…”

Abstract:In this study the effect of pore structure on the mechanical properties and durability characteristics of Self-Compacting Mortars (SCM) containing nano-Al 2 O 3 (NA) and class F fly ash are investigated. Al 2 O 3 nanoparticles with the maximum size of 15 nm in three different proportions of 1, 3 and 5% of the binder content were utilized to partially replace the cement. The 25% of the cement weight was also replaced by class F fly ash. The pore structure of cement mortars was determined through the Mercury Intrusion Porosimetry (MIP) and Gas Adsorption (BET) methods. The microstructure of the SCMs was evaluated by Scanning Electron Microscopy (SEM). The results indicated a reasonable correlation which was observed between the pore structure and other properties of mortars. The addition of the NA at proportions over 1% led to an increase in the pore volume of specimens by virtue of agglomeration. In overall, it seems that 1% NA can be considered as a suitable replacement regarding the pore structure and hardened properties.

Abstract. Self-compacting concrete is a very perspective building material. It provides great benefits during the construction of heavily reinforced buildings. SCC has outstanding properties such as high flowability, dense structure and high strength due to specific quality of aggregates, fillers, their proportion in mix, use of polycarboxylate-based superplasticizers. Main disadvantages of SCC are high price and the difficulty of obtaining a proper mix. Use of fillers, such as fly ash type F, is a way to make SCC cheaper by replacing part of cement. Fly ash also provides some technological and operating advantages. In this paper the influence of high volume (60% from cement) fly ash type F on the properties of concrete mixture and hardened concrete is investigated. The result of the work shows the possibility of reduction the cost of SCC using ordinary fillers and high amount of fly ash. The investigated SCC has low speed of hardening (7-day compressive strength at the range of 41.8 MPa) and high volume of entrained air content (3.5%).
