“…The final concrete mixture contained GGBS and SF as substitute cementitious materials. The reason for choosing those two materials isthat they are the most common cement substitutesused within the UAE [15,16].…”

Highlights• This work studies the application of thermogravimetric analysis, differential scanning calorimetry, X-ray diffraction and petrography as tools for revealing the thermal history on concrete structures.• • Other reactions can be reversible, particularly the dehydroxylation of Portlandite.The thermal history can still be determined though by comparing the onset temperature of reformed components with Portlandite in non-previously heated samples.

“…The observations were that those concretes had lower temperature rise due to heat of hydration, were less prone to experience thermal cracking, and had generally low compressive strength at early ages. Since that pioneering study by Davies et al [15], a significant amount of research has been conducted on concretes containing high volumes of FA [16][17][18][19][20][21][22][23][24] and high volumes of GGBFS [25][26][27][28][29].…”

“…Blast furnace slag is the by-product of iron/steel industry and is widely used in concrete as partial replacement of cement. Its use up to 60-70% as partial replacement of cement in concrete is researched (Elchalakani et al, 2014). It has been reported that above this limit the mechanical and durability properties are significantly affected (Oner and Akyuz, 2007).…”

This paper presents the effect of nano alumina (NA) on compressive strength and microstructure of cement paste containing high volume blast furnace slag (HVBFS) contents of 70, 80, and 90% as partial replacement of cement and combined blast furnace slag (BFS) and class F fly ash (FA) contents of 70 and 80% as partial replacement of cement. FA is used at 30% as partial replacement of BFS. NA contents are varied from 1 to 4% as partial replacement of BFS and BFS-FA. Results show that the addition of NA improves the compressive strength of high volume BFS and BFS-FA pastes by 2 to 16%. The compressive strength of paste containing 69% BFS, 30% cement, and 1% NA exceeded the compressive strength of control cement paste while the compressive strength of paste containing 77% BFS, 20% cement, and 3% NA is 1% lower than control cement paste. NA significantly reduced the large capillary pores of >0.1 microns of high volume BFS and BFS-FA pastes. No evidence of reduction of Ca(OH) 2 in high volume BFS pastes is observed due to addition of NA, however, in high volume BFS-FA paste the Ca(OH) 2 is reduced due to addition of NA. Increase in intensity peaks of CAH, Ettringite and CSH in X-ray diffraction analysis is observed in high volume BFS and BFS-FA pastes due to addition of NA, which coincides with the observed more dense microstructure of high volume BFS and BFS-FA pastes containing NA than those without NA.
