【Abstract】 The paper introduces a high strength and abrasive-resistance concrete admixture. And by the analysis methods of XRD, SEM, DTA, EDXA, bonding water measurement and Ca(OH)2 measurement, the effects made by this admixture to the cement hydration substances, structures of hydration substances, hydration speed and hydration extent were studied and observed. Besides, the effects of this admixture to concrete structure has been also studied and analyzed through the cavity structure measurement and micro-hardness measurement etc.The impact mechanism of this admixture to improve concrete strength and abrasive-resistance effect have been finally concluded.更多还原
