コンクリートの配合設計方法
Document Type and Number:
Japanese Patent JP7352529
Kind Code:
B2
Abstract:
To provide a mix design method for concrete having high fluidity, which can contribute to streamlining and labor saving thereof.SOLUTION: The present invention provides the mix design method for the concrete in which an amount of powder material, an amount of water, an amount of fine aggregate, an amount of coarse aggregate and an amount of chemical admixture are determined so that a capacity ratio (Vwo/Vfp) of "a water amount for evaluation Vwo corrected by a water amount Vw specified in the mix design method in consideration of an amount of chemical admixture" to "a fine grain amount for evaluation Vfp obtained by adding an amount of a fine grain effective for material separation resistance among fine aggregate to a powder material amount Vp" is less than or equal to a predetermined upper limit Rmax.SELECTED DRAWING: Figure 1
