Abstract

In order to help achieve the “dual carbon” goal in the cement industry, new engineering materials are actively introduced into green buildings, and a new type of multi solid waste low-carbon cementitious material is developed to replace traditional cement. This article uses granulated blast furnace slag (GBFS), fly ash (FA), municipal solid waste incineration fly ash (MSWI FA), NaOH, and liquid water glass to prepare ternary geopolymer cementitious materials, and explores the influence of various ratios between cementitious systems on mechanical properties. And X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR) were used to analyze its microstructure, revealing its macroscopic mechanical properties and microstructure evolution mechanism. The macroscopic results indicate that the modulus of water glass has a significant impact on the flow properties of cementitious materials; The compressive strength of the specimen shows a peak with the increase of water glass modulus and alkali content. The microscopic results show that with the increase of curing age, the hydration products of the specimens are mainly calcium silicate hydrate gel (C-S-H) and calcium aluminosilicate hydrate gel (C-A-S-H). The gel products increase, forming a dense structure, significantly enhancing the strength characteristics of engineering materials.
