Setting and mechanical properties of alkali-activated fly ash/slag concrete manufactured at room temperature
Namkon Lee,Haeng-Ki Lee +1 more
TL;DR: In this paper, a series of tests of the compressive strength, elastic modulus, splitting tensile strength, flow, setting time, and porosity of the alkali-activated fly ash/slag concrete were carried out.
Journal ArticleDOI
Shrinkage characteristics of alkali-activated fly ash/slag paste and mortar at early ages
TL;DR: In this article, the shrinkage characteristics of fly ash/slag and the factors affecting it were investigated and a series of tests were conducted to determine the chemical shrinkage, autogenous shrinkage and drying shrinkage.
Journal ArticleDOI
Enhanced effect of carbon nanotube on mechanical and electrical properties of cement composites by incorporation of silica fume
TL;DR: In this paper, a qualitative analysis using SEM images was carried out to observe the surface morphology and microstructure of cement composites with different amounts of silica fume and CNT addition.
Journal ArticleDOI
Workability, and mechanical, acoustic and thermal properties of lightweight aggregate concrete with a high volume of entrained air
TL;DR: In this paper, the effects of lightweight aggregates and entrained air on the flow characteristics, density, porosity, compressive strength, and dynamic elastic modulus of the concrete were investigated.
Journal ArticleDOI
Fresh and hardened properties of alkali-activated fly ash/slag pastes with superplasticizers
TL;DR: In this paper, the results of an experimental study carried out to investigate fresh and hardened properties of alkali-activated fly ash/slag pastes with superplasticizers were presented.
