A comprehensive evaluation of sedimentary zeolites from Turkey as pozzolanic addition of cement- and lime-based binders
(Elsevier Sci Ltd, 2016)
The pozzolanic action played by five natural zeolite-rich materials (three clinoptilolite- and one each mordenite- and analcime-bearing rocks) coming from Turkey, has been examined, evaluating also the influence of various ...
Stability analyses of submicron-boron mineral prepared by mechanical milling process in concrete roads
(Elsevier Sci Ltd, 2016)
The main objective of this study is to investigate the possibility of utilizing nano/submicron sized boron mineral (colemanite) in Portland cement concrete. Colemanite was obtained from a mine in three different sizes as ...
CT scanning of internal crack mechanism and strength behavior of cement-fiber-tailings matrix composites
(Elsevier Ltd, 2021)
This paper deals the relationship between compressive strength and internal crack formation (e.g., crack width and volume) of cement-fiber-tailings matrix composites (CFTMC) using an industrial computed tomography system ...
Additivity effect on properties of cemented coal fly ash backfill containing water-reducing admixtures
(Elsevier Ltd, 2021)
Cemented coal fly ash backfill (CCB), a flowable structure of coal fly ash, binding agent and mixing water, has been often employed in mining operations to offer ground support as well as waste disposal solutions. An ...
Utilizing concrete pillars as an environmental mining practice in underground mines
(Elsevier Ltd, 2021)
Ground control is an integral element of mine design and worker safety. The use of concrete pillars for underground mines is of paramount importance to maintaining the economic and operational security of structures. This ...
Development and characterization of clinoptilolite-, mordenite-, and analcime-based geopolymers: A comparative study
(Elsevier, 2021)
This study examines the development of geopolymers from clinoptilolite, mordenite, and anal-cime and compares the properties of the resulting green-binding materials. Sodium silicate and sodium hydroxide solutions were ...
Sodium silicate effect on setting properties, strength behavior and microstructure of cemented coal fly ash backfill
(Elsevier, 2021)
Representing an engineered mixture of coal fly ash, cement and water, cemented coal fly ash backfill (CCB) is typically employed for filling the openings created after coal excavation in the earth. A high rate of productivity ...
Transition coefficients between compressive strengths of samples with different shape and size in mass concrete and use of weight maturity method in dam construction
(Ernst & Sohn, 2019)
Mass concrete (MC) is widely used in dam concretes due to their large aggregate grain diameters, low cement dosage, and low hydration temperatures. Monitoring of the hydration temperature and compressive strength is an ...
Compressive strength and microstructural characteristics of natural zeolite-based geopolymer
(Budapest Univ Technology Economics, 2018)
A detailed study of geopolymeric reaction products and mechanical properties of geopolymer pastes prepared with natural zeolite has been investigated by means of compressive strength, XRD and SEM/EDX analysis. Sodium ...
Novel binder material in geopolymer mortar production: Obsidian stone powder
(Wiley, 2023)
This paper presents the results of mechanical and micro-structural properties of geopolymer mortars with obsidian, ground granulated blast furnace slag, and metakaolin. In this study, 13 different combinations were created ...
