...Abdul Basit Bhat; Shashi Kant Sharma; Mudasir Nazeer; Aijaz Hussain Bhat This study investigates the influence of supplementary cementitious materials (SCMs), namely fly ash ( FA ) and silica fume ( SF ), on the fresh, mechanical, durability and microstructural properties of pervious concrete...

...Jacek Kwasny; Marios Soutsos The use of lagoon fly ash ( LFA ) was investigated as a precursor for alkali-activated/geopolymer concretes. The chemical composition, particle size distribution, mineralogy and morphology of LFA obtained from Kilroot power station ( KLFA ) were evaluated and compared...

.... The physical properties of an ecologically friendly concrete – using fly ash (FA) as a fine aggregate substitute for sand – were examined in this study. Both destructive and non-destructive testing techniques were used to evaluate the concrete properties. After creating concrete mixtures with 10–50...

... ingredients. Setting times, compressive strengths, and flow values are strongly affected by mixture characteristics such as the magnesia to phosphate molar ratio, water to cementitious materials ratio, chosen phosphate component and replacement rates, set retarder type, set retarder dosage, fly ash type...

...Leo Gu Li, PhD; Zhi-Quan Fang, MEng; Shao-Hua Chu, PhD; Albert Kwok Hung Kwan, PhD Fly ash microspheres (FAM), being a superfine fly ash, and nanosilica (NS), being an ultrafine amorphous silica, have proven to be useful for enhancing the performance of traditional cement-based materials...

...Hyun-Do Yun; Wan-Shin Park; Young-Il Jang; Sun-Woo Kim This paper deals with the proposal of a model that can predict the heat of hydration of concrete containing fly ash and the adiabatic temperature rise test results that are the basis of the model. For the adiabatic temperature rise tests...

...Paramveer Singh; Kanish Kapoor To develop a sustainable geopolymer concrete (GC), the efficacy of using fine recycled concrete powder (FRCP) and recycled aggregates (RA) as partial replacements for fly ash (FA) and natural aggregates (NA), respectively, was investigated. The compressive strengths...

... coarse aggregate (NCA) was replaced with CRCA at 0%, 20% and 100% of the total coarse aggregate content by weight. The cement, fly ash, silica fume and water were kept constant for all SCC mixtures. The effects of CRCA on the flow behaviour, mechanical strength, shrinkage characteristics...

... and permeation tests in order to consider the existence of aggregate induced in the interfacial transition zone (ITZ). Tortuosity gained through the corrugated pore structure model and the Katz–Thompson model are compared and analysed to quantify the tortuosity of fly ash concrete. The ITZ was observed...

...Yurong Zhang; Xueqing Ma; Sishi Du; Yun Zhang Based on the exposure test of fly ash (FA) concrete in different environments, chloride diffusion coefficients and main microstructural parameters measured by mercury intrusion porosimetry and their time-dependent properties were analysed...

...Bowen Wang; Yang Liu; Dong Luo; Yiwei Yang; Dunwen Huang; Hui Peng The dissolution rates of alkali-activated fly ash (FA) and alkali-activated slag in hydrochloric acid (HCl) with various pH values were investigated. The geopolymerisation reaction degree of alkali-activated FA/slag (AAFS) can...

... the shrinkage of blended cement-based concrete is essential. In total, 21 concrete mixes were produced with type general purpose cement and with cement replacements of 30% by fly ash, 40% and 60% by ground granulated blast furnace slag (GGBFS). The concrete compressive strength ranged from 25 MPa to 100 MPa...

...Jelena Dragaš; Ivan Ignjatović; Nikola Tošić; Snežana Marinković A two-phase experimental study on the effect of simultaneous partial replacement of cement and fine aggregate with fly ash on the mechanical and time-dependent properties of high-volume fly ash concrete (HVFAC) is presented...
