The effect of fly ash on the mechanical properties of cinder lightweight aggregate concrete

Abstract

The volcanic cinder is a kind of porous rock with good performance and is formed by the cooling of the volcanic eruption. This paper studies the effect of fly ash on the mechanical properties of cinder lightweight aggregate concrete. Results show the mechanical properties of cinder lightweight aggregate concrete is significantly improved with fly ash, and it has a maximum strength value when the dosage is 35%; the early strength of lightweight aggregate concrete is greatly improved, when we extend the grinding time of fly ash, decrease the particle size and increase the activity.
