Natural Pozzolan as a Partial Substitute for Cement in Concrete [PDF]

open access: yesThe Open Construction and Building Technology Journal, 2013
In this paper, the use of natural pozzolan as a partial cement substitute in concrete materials is investigated. By means of a test series, four mixes using three types of natural pozzolan, as well as a Class F fly ash, are evaluated. The effectiveness of each pozzolan in controlling alkali-silica reactions has been studied.

Mix Proportion of Fly Ash Concrete Based on the Strength Contribution Ratio

open access: yesJAPAN ARCHITECTURAL REVIEW, Volume 9, Issue 1, January–December 2026.
ABSTRACT This study aims to expand the use of fly ash concrete (FAC). Based on an experimental investigation of k values or the contribution of FA addition to the strength of ordinary Portland cement or Portland blast‐furnace slag cement type B, we propose and validate an environmentally friendly mix design for FAC.
