[1C14] Leaching Behavior of Chemical Admixture from Cementitious Material

*Daisuke Minato1, Takeshi Yamamoto1, Tetsuro Sakakihara2 (1. Central Research Institute of Electric Power Industry., 2. Shikoku Electric Power Co. Inc)

Keywords:absorption, chemical admixture, cement colloid, steelmaking slag

We investigated the leaching behavior of chemical admixture from cementitious materials etc which replaced slag at a high rate.
From the results of the dynamic light scattering, it was shown that the chemical admixtures were not leaced from the hardened cement paste.
