“…According to Mehmedi et al [ 60 ] and other related researchers, natural diatomite is chemically composed of 67.80 to 90.07% silica (SiO 2 ), 0.62 to 10.30% alumina (Al 2 O 3 ), 0.20 to 6.85% iron oxide (Fe 2 O 3 ), 0.05 to 1.21% titanium oxide (TiO 2 ), 0.04 to 0.21% phosphate (P 2 O 3 ), 0.19 to 3.0% limestone (CaO), 0.11 to 1.64% magnesium (MgO), 0.13 to 0.97% sodium (Na 2 O), and 0.13 to 1.47% potassium (K 2 O), wherein the first values are the minimum while the second values are the highest. Hasan et al [ 126 ] defined diatomite as microparticles that can be utilized to substitute cement in concrete production, even though its silica content and structure differ greatly from one source to the next.…”

A Review on the Incorporation of Diatomaceous Earth as a Geopolymer-Based Concrete Building Resource

et al. 2022

The development of geopolymer building composites at a lower cost with a smaller carbon footprint may lessen the growing concerns about global warming brought on by emissions of a critical greenhouse gas (CO2) paired with the high production costs in the cement sector. Diatomaceous earth, commonly used as an admixture or partial replacement of cement owing to its most effective pozzolanic properties, has been investigated as a precursor in geopolymer concrete development. Several studies have been examined to develop a greater understanding of its characterization, inclusion status, and impacts on the performance aspects of concrete. The literature review showed that using diatomaceous earth is one of the effective ways to create sustainable, insulating, lightweight building materials while minimizing the harmful economic and environmental effects of industrial solid wastes. However, since most studies have focused on its integration as a partial cement substitute or a replacement for fine aggregate, further research on diatomaceous earth-based clinker-free concrete is required. A lack of research on geopolymer concrete’s reinforcement with either natural or synthetic fibers, or a combination of the two, was also discovered. This review also showed that there has been remarkably little effort made towards theoretical property correlation modeling for predicting concrete performance. It is anticipated that the detailed overview presented herein will guide potential researchers in defining their future paths in the study area.

“…With this background, the work presented in this paper studied and evaluated the improvement of geopolymer alkalinity and PC planting performance using high silicon sources. In the study, two high silicon sources, namely, silica fume (SF) and diatomite (DA) [28][29][30][31], respectively, were selected to replace BFS in different proportions to comparatively evaluate the effects of different high silicon sources on the properties of geopolymerbased PC. To better reduce the alkalinity of the geopolymer, this study used A (alkali solid content)/P (powder dosage) as one of the variables to quantify the performance variations of the geopolymer-based PC as a function of different A/P ratios.…”

In order to reduce the carbon emission of planting concrete in the process of preparation, and to realize the application of large amounts of red mud in the geopolymer, in this study, high silicon source materials and blast furnace slag are added to a large content of red mud base geopolymer planting concrete, which can remove the dependence of planting concrete on ordinary Portland cement and provide a new direction for the comprehensive utilization of red mud. In the paper, the effects of different A (Alkali solid content)/P (Powder dosage) and high silica sources (silica fume and diatomite) on the microstructure and fluidity of the geopolymer, as well as the compressive strength, pore characteristics, and alkalinity of the planting concrete, are comparatively evaluated. The corresponding results showed that when A/P was 0.25, the planting performance of the planting concrete would be reduced due to its high alkalinity; when A/P was 0.15, the planting concrete would have its sedimentation and the compressive strength decreased. On the other hand, the pozzolanic reaction among the silica fume, diatomite, and Ca(OH)2 significantly weakened the alkali pan phenomenon in the later stage of planting concrete formation. The addition of an appropriate amount of silica fume and diatomite also made the structure of the geopolymer more compact with better fluidity, which yielded superior pore characteristics and planting performance for the planting concrete. For good planting concrete pore characteristics, the test results showed that the fluidity of the mortar should be 112–128 mm. Overall, the best planting concrete performance was achieved at an A/P ratio of 0.2, with the contents of silica fume and diatomite being 10% and 5%, respectively. Furthermore, the slope finite element analysis showed that planting concrete made with red mud geopolymer had better slope protection potential than ordinary Portland cement.

“…In addition, it has also been developed in the local Aceh Province using diatomaceous earth as a silica source [6]. Diatomaceous earth is, however, the silica-rich material which has the ability to function as supplementary cementing material [7]. The use of local materials has an impact on the development of RPC in Indonesia and also enrich the substance of research on this concept.…”

Original reactive powder concrete (RPC) consists of a large amount of cement, fine sand, crushed quartz, and silica fume, with a very dense matrix achieved by optimizing the granular packaging of the materials. This study, therefore, applied the modified Andreasen & Andersen particle-packing model using Aceh quartzite powder to design a densely compacted matrix and low cement content RPC mixtures. The research involved the preparation of two series of the mixture with different percentages of silica fume and Aceh quartzite powder and the 70.7 mm cube specimens were treated with combined steam curing and normal curing after which their compressive strength was tested at the age of 7 days and 28 days. The result showed the use of 61% local quartzite powder by weight of cement through an optimized mix design and cured treatment improves the RPC strength at any variation of silica fume.
