The Effect of Slag on the Mechanical Properties of Coralline-Activated Materials and the Formation and Transformation of Mineral Crystals
TL;DR: In this paper, the compressive strength of the developed composites was evaluated at different ages, and the formation and transformation of mineral crystals in coralline-activated samples were further analyzed by XRD (X-ray diffractometer).
Compressive Strength Enhancement in Early Age Acid Activated Mortars: Mechanical Properties and Analysis
TL;DR: In this paper , different types and proportions of acids were mixed into mortars to increase the hydration reaction rate and the amount of hydration products, and the effects of the acid type and content on the early compressive strength of cement-based materials and the strengthening mechanism were assessed via X-ray diffraction and Fourier transform infrared spectrum analyses.
Preparation and Properties of Municipal Solid Waste Incineration Alkali-Activated Lightweight Materials through Spontaneous Bubbles
TL;DR: In this paper , a self-foaming alkali-activated lightweight material was prepared by pretreatment of municipal solid waste incineration bottom ash (BA), which was achieved without adding a foaming agent by using the low-density and self foaming expansion characteristics of BA in combination with a strong alkali.
