    • 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%。

    • PURPOSE: An apparatus and a method of managing the quality of ready mixed concrete are provided to inform the defection of ready mixed concrete by monitoring the state of the ready mixed concrete in a production step. CONSTITUTION: A sensing unit(120) detects the input amount of each components in a ready mixed concrete product, and a calculation unit(140) measures the input value for each component, and calculates the production error for each component of the ready mixed concrete product based on the measurement value and the input amount. A judgment processing unit(150) judges the defection of the ready mixed concrete product based on the production error and an error allowance range, and generates an alarm signal according to the judgment result. An alarm unit(160) alarms the defection of the ready mixed concrete product based on the alarm signal.
    • 目的:提供一种管理混合混凝土质量的设备和方法,以便通过在生产步骤中监测预混混凝土的状态来告知预混合混凝土的缺陷。 构成:感测单元(120)检测准备好的混合混凝土产品中的每个部件的输入量,并且计算单元(140)测量每个部件的输入值,并计算准混合混凝土的每个部件的生产误差 产品基于测量值和输入量。 判断处理单元(150)根据生产误差和误差容许范围来判断就绪混合物的偏差,根据判断结果生成报警信号。 报警单元(160)根据报警信号报警混合混凝土产品的脱落。
