The research result indicated that on the condition of the same mortar fluidity, the preventing effects of mineral and superplasticizer compounded on aar are better than that of mineral used singly, the preventing effects of mineral admixture and entraining agent compounded are better than that of mineral admixtures used singly, the preventing effects of mineral and superplasticizer and entraining agent compounded are lower than that of mineral admixture and entraining agent compounded. the research achievement has some guiding sense on the recognition of aar prevention in pumping hpc and the researches of test methods for determining the alkali reactivity of aggregate used in hpc
研究結果表明：在相同砂漿流動度條件下，減水劑與礦物摻合料復合使用對堿?骨料反應的抑制作用大於礦物摻合料單獨使用的抑制作用；引氣劑與礦物摻合料復合使用對堿?骨料反應的抑制作用優于礦物摻合料單獨使用的抑制作用；減水劑、引氣劑與礦物摻合料三元復合使用對堿?骨料反應的抑制作用小於引氣劑與礦物摻合料二元復合使用的抑制作用。 -
