“…The two small peaks at the right and left side of the main peak in the 800-1100 cm À1 region indicate the presence of C 2 S [38]. The decrease in these two small peaks in line with the increasing hydration time indicates that the cement paste is setting.…”

“…For the reason, red mud is reported to be capable of replacing conventional soil pavement with sufficient quality (Liu et al 2011;David et al 2017;Kang 2016). Another effort for utilizing red mud as an activator has been made for alkali slag red mud cement in the construction industry, which is so called clinker-free cement (Gonga and Yang 2000;Pan et al 2002Pan et al , 2003. On the other hand, several studies have been carried out for the use of a powdery industrial byproduct as a replacement for expensive liquid activator (Kang 2012).…”

Efflorescence which severely occurs in alkali-activated slag cement can cause reduction of strength and durability due to calcium leaching. In the work, efflorescence characteristics in pavement containing red mud which can be affected by strong alkaline were investigated through various tests such as compressive strength, porosity, absorption, efflorescence area, alkali leaching content, and properties of the efflorescence compound. The compressive strength of pavement was evaluated to be higher over 15.0 MPa in all cases regardless of replacement ratio of red-mud and binder type, which can provide a reasonable strength for walking and bike lanes. The pavement with red mud was applicable to parking lots only when the replacement ratio of red-mud is within 10%. The efflorescence area increased with a higher replacement ratio of red mud and its propagation appeared though the efflorescence was removed through evaporation of moisture. However, the area of efflorescence gradually decreased with the repetition of the test.

“…Shi and Quian (2000) reported mortars based on alkali activation of slag with 160 MPa in compressive strength cured at room temperature after 28 days. The use of binary systems combining slags with other alumino-silicate source materials is also reported in several papers (Gordon et al, 2011;Escalante-García et al, 2006;Pan et al, 2002;Kumar et al, 2010). Bernal et al (2011) reported some studies about alkali activated binders prepared with slag-metakaolin blends.…”

In most cases, the setting-hardening process of this binder is performed at high curing temperatures. In this paper, alkali activated mortars based on Vitreous Calcium Aluminosilicate (VCAS) cured at room temperature are evaluated. Mechanical strength development and microstructural analysis (scanning electron microscopy, thermogravimetric analysis, X-ray diffraction and mercury intrusion porosimetry) of these materials are performed. Mortars yielded compressive strength around 89 MPa after 360 days. This is the first time that VCAS is used as alumino-silicate source material in the production of alkali activated mortars cured at room temperature.
