Abstract Coral materials can replace concrete aggregates and achieve material self-sufficiency for reducing the construction
costs of island projects. This paper studies the effects of different mineral admixtures on the properties of coral
aggregate concrete (CAC). The chloride concentration of CAC after different erosion times is measured using the
potentiometric method, and the porosity of the CAC is calculated using thermogravimetric and drying methods.
The chloride concentration of the CAC presents a two-phases distribution. The peak chloride concentration followed a power function, increasing with the erosion time. The chloride diffusion coefficient of CAC is 7.9%–
37.5% larger than that of ordinary… More >
