Degradation resistance of different cementitious materials to phosphoric acid attack at early stage
TL;DR: In this paper, the early stage of the degradation process of different cementitious materials in phosphoric acid was studied and the degradation kinetics, chemical and microstructural properties as well as dissolution rate of these binders were analyzed.

Pre- and post-heating behavior of concrete-filled steel tube stub columns containing steel fiber and tire rubber
TL;DR: In this paper, the axial compressive behavior of short concrete-filled steel tube (CFST) columns with rubberized concrete core when they are exposed to elevated temperature was investigated.
Journal ArticleDOI
Effects of red mud on the properties of fresh and hardened alkali-activated slag paste and mortar
TL;DR: In this paper, a study was conducted to investigate the effect of red mud (RM) and thermally treated at 550 and 750°C (at 40%) on the performance of an AAS system.

Incorporation of cement bypass flue dust in fly ash and blast furnace slag-based geopolymer
TL;DR: In this article, the authors used ground, granulated blast furnace slag with fly ash and cement bypass flue dust to construct a geopolymer, which is formed in the solid state like ordinary Portland cement.
Journal ArticleDOI
Investigation of sulfuric acid attack upon cement mortars containing silicon carbide powder
TL;DR: In this paper, silicon carbide particles play an important role by filling the pores inside the cement composites and densifying the microstructure due to the filler effect, and this behavior was enhanced with the increase in silicon carbides content.

Compressive strength of concrete at high temperatures: a reassessment
TL;DR: In this paper, a reassessment of the subject is given, which considers material and environmental factors/mechanisms influencing the strength of concrete during the heat cycle and after cooling, not all of which necessarily result in strength loss.

Thermal stability and decomposition mechanisms of ettringite at <120°C
Q. Zhou,Fredrik P. Glasser +1 more
TL;DR: In this article, the decomposition and reformation of ettringite is studied as a function of water vapour pressure and temperature, and the authors make recommendations for the upper safe service limits for ETTringite-based cements.
Journal ArticleDOI
Physicochemical, mineralogical, and morphological characteristics of concrete exposed to elevated temperatures
TL;DR: In this paper, the effect of elevated temperatures on the mineralogical changes occurring in the hydrated phases of concrete cubes were studied by measuring ultrasonic pulse velocity (UPV) and consequent deterioration in the compressive strength with increase in temperature.
