Abstract: | In the process of preparing for Shereik Hydropower Project in Sudan, special indoor test on four kinds of local natural pozzolans have been carried out, which including the test for the influence of pozzolanic admixtures on activity index, the test for the effect of' pozzolan's inhibition on alkali reactivity of aggregate, the test for the intluence of pozzolan on concrete strength and hydratation heat of eementitious material. Special analyses and research of the feasibility to substitute pozzolan for flyash have been done. |

Keywords: | natural pozzolans fly ash amount of admixture alkali reactivity hydratation heat strength |
