Effects of Different Mineral Admixtures on the Properties of Fresh Concrete
TL;DR: A review of the properties of fresh concrete including workability, heat of hydration, setting time, bleeding, and reactivity by using mineral admixtures fly ash, silica fume, ground granulated blast furnace slag, metakaolin, and rice husk ash is presented.
Journal ArticleDOI
Mechanical Properties of High-performance Concrete Reinforced with Basalt Fibers
TL;DR: In this article, the influence of addition of 1, 2 and 3% Basalt fiber volume fraction in three different mixes of high-performance concrete (HPC) is investigated and the results showed that the addition of up to 2% fiber volume together with mineral admixtures improved the compressive strength.
Journal Article
Effect of sodium hydroxide concentration on fresh properties and compressive strength of self-compacting geopolymer concrete
TL;DR: In this article, the effect of sodium hydroxide concentration on the fresh properties and compressive strength of self-compacting geopolymer concrete (SCGC) was investigated by varying the concentration of sodium hyroxide from 8 M to 14 M.
Journal ArticleDOI
Calcined kaolin as cement replacing material and its use in high strength concrete
TL;DR: In this article, the effects of temperature and duration on Malaysian kaolin to form highly reactive metakaolin have been examined and it was found that locally produced metakaolins enhance the mechanical properties of concrete and compressive strength is about 5% higher than silica fume concrete at the age of 28 days.
Journal ArticleDOI
Effect of Chopped Basalt Fibers on the Mechanical Properties and Microstructure of High Performance Fiber Reinforced Concrete
TL;DR: In this paper, the microstructure of the high performance fiber reinforced concrete (HPFRC) was examined to determine the interfacial transition zone (ITZ) between the aggregates and the paste by using field emission scanning electron microscope (FESEM).
