    • The present invention relates to high-volume mineral admixture (HVMA) concrete whereby the ratio of admixture use in a binding material is increased and, more particularly, to an alkali activator which activates pozzolan powder or latent hydraulic property powder used as an admixture for a concrete composition, an admixture which has a cement particle dispersion function, an alkali activator function, and a strength-enhancing function at the same time, and a HVMA concrete composition using the same. The present invention contains a binding material, water, fine aggregate, and thick aggregate. The binding material is obtained by mixing Portland cement and an admixture. The admixture contains one or both of pozzolan powder and latent hydraulic property powder, where 60-90 wt% is contained in the binding material. The alkali activator for aqueous-solution HVMA, which contains 5-15 wt% of Na_3PO_4, is added, and the Na_3PO_4 is added by 0.025-0.05 wt% with respect to the binding material.
    • 本发明涉及大体积矿物混合物(HVMA)混凝土,其中在粘合材料中使用的混合物比例增加,更具体地说,涉及一种活化火山灰粉末或潜在水硬性粉末的碱活化剂,其用作混合物的混合物 混凝土组合物,同时具有水泥颗粒分散功能,碱活化剂功能和强度增强功能的混合物,以及使用其的HVMA混凝土组合物。 本发明包含粘合材料,水,细骨料和厚骨料。 通过混合波特兰水泥和外加剂获得粘合材料。 混合物含有火山灰粉末和潜在水硬性粉末中的一种或两种,其中粘合材料中含有60-90重量%。 添加含有5-15重量%Na 3 PO 4的水溶液HVMA的碱活化剂,相对于粘合材料,Na 3 PO 4添加0.025-0.05重量%。
