TL;DR: In this article, a new lightweight building material based on incorporating raw rice husk and foam bubbles in magnesium oxysulfate cement paste was presented, and phase composition, air bubble distribution and microstructure were studied on typical samples by using XRD (X-ray diffraction), FTIR (Fourier transform infrared spectroscopy), OM (opto-digitial microscope) and SEM (scanning electron microscope) facilities.

TL;DR: In this paper, the influence of limestone powder, fly ash and ground granulated blast-furnace slag (GGBS) on carbonation curing of cement pastes was investigated.

TL;DR: In this article, compressive strength, flexural strength and fracture toughness of ultra-high performance concretes (UHPC) containing silica fume and different dosage of fly ash (0, 10, 20% and 30%) after exposure to different autoclave curing conditions with pressure of 0.5

TL;DR: In this paper, the role of steam curing in performance of precast concretes incorporating self-ignited coal gangue (CG) particles was evaluated. And the authors concluded that the combination of a suitable steam curing regime and a proper CG content could realize the production of green concrete with excellent durability, low cost and substantial environmental benefit.

TL;DR: In this article, a partial differential mathematical model was developed for the coupling behavior of cement hydration and carbonation reaction of both clinker minerals and hydration products when cement paste is exposed to an accelerated carbonation curing at early age.
