本研究探討綠設計水工混凝土之工程性質與磨耗性能，試驗變數包括水膠比 (W/B = 0.3、0.4、0.5)、砂率 (S/A = 40%、50%、60%)、矽灰含量 (SF = 0%、5%、10%)及聚丙烯纖維量 (PP = 0%、0.1%、0.2%)等項，試驗配比採用田口法規劃，並輔用變異數分析及雜訊比等統計方法，了解各因子對於混凝土性質影響程度；隨後另以固定水膠比，改變砂率、矽灰及纖維含量方式，探討其三項因子對混凝土工程及磨耗性質之關聯性。
研究結果顯示：(1) 由田口試驗法中，水膠比與聚丙烯纖維量對新拌性質有顯著影響；對於超音波波速、動態彈性及剪力模數、抗壓強度及劈裂強度等性質，水膠比為最大影響因子，其貢獻度也最大；於56天齡期，矽灰含量為表面電阻及氯離子滲透試驗主要影響因子，其次為水膠比；不論乾濕環境，水膠比對磨耗性質之影響最為顯著，而影響最低因子為矽灰含量；濕混凝土試體在超音波波速與動態彈性及剪力模數其數值皆大於乾混凝土試體；但抗壓強度及劈裂強度則降低。(2) 依據本研究綠設計試驗配比進行評核，結果顯示混凝土各配比之選料及用量皆能通過緣設計配比指標要求之60~77%；綠混凝土性能評核中，大部分混凝土配比所製作混凝土皆能通過綠混凝土性能新拌性質及耐久性指標要求之49~83%。(3) 全因子試驗中，當混凝土砂率由40%增加至60%，不論是否添加纖維，坍流度皆呈下降趨勢，混凝土添加矽灰及纖維數量增加時，皆造成坍流度呈下降趨勢；混凝土超音波波速、動態彈性及剪力模數和抗壓強度皆隨砂率提升而下降，隨矽灰及纖維添加量增加而提升；混凝土表面電阻隨砂率提升而下降約0.44~14.79%。添加矽灰則增加5.98~73.68%。添加纖維量也增加表面電阻約0.26~19.32%；乾濕混凝土磨耗性質皆隨增加砂率、添加矽灰量及纖維量而提升， (4)當混凝土超音波波速超過約4600 m/s 、動態彈性模數超過約36 GPa、剪力模數超過約13.5 GPa、抗壓強度超過約45 MPa及抗彎強度超過6.2 GPa時，混凝土磨耗損失率約維持在3.2~3.5%。

This research mainly focuses on the investigation of engineering properties and abrasion resistance capability for the hydraulic concrete with green design. Experimental variables include the water-to-binder ratios (W/B = 0.3、0.4、0.5), the percentage of sand (S/A = 40%、50%、60%), amount of silica fume (SF = 0%、5%、10%), and amount of polypropylene fiber (PP = 0%、0.1%、0.2%). The Taguchi method for mix proportion together with the statistical methods of ANOVA and signal-to-noise (S/N) ratio were used to understand the influence of each factor on the response. Afterward, at a fixed water-cement ratio, variations of the percentage of sand, amounts of silica fume and fiber were used as the factors to study the correlation among the engineering properties and abrasion resistance capability.
The results of study shows that：(1) From the Taguchi experimental method, the water-cement ratio and polypropylene fibers significantly affect the fresh property; for the properties of ultrasonic pulse velocity, dynamic of elastic modulus, dynamic of shear modulus, compressive strength and splitting tension strength, the water-binder ratio is the maximum impact factor and has the greatest contribution; at the age of 56 days, the silica fume content is the main factor in the surface resistivity and chloride penetration test, followed by water-binder ratio; wet concrete specimens have higher values of ultrasonic pulse velocity, dynamic modulus of elasticity and dynamic shear modulus but lower values of compressive and splitting tensile strengths than those for dry concrete specimens; (2) From the evaluation on the criteria of material selection and amount of usage of mixture proportion with green design, it is found that all the mixtures in this study can reach the index requirement by 60~77%, and from the performance evaluation, most of the mixtures in this study can reach the index requirement by 49~83%. (3) The results from the full factorial experiment show that when the percentage of sand increases from 40 % to 60 %, regardless if the fiber is added or not, the slump flow tends to reduce and similar tendency of reduction in slump flow was observed when the silica fume and fiber were added to the mixture; the ultrasonic pulse velocity, dynamic of elastic modulus, dynamic of shear modulus, and compressive strength of concrete specimen are decreased with the increase of the percentage of sand, and increased with the increase of silica fume and fiber contents; the sand surface resistivity of concrete decreases with the increase of the percentage of sand by 0.44 ~ 14.79 %, increases with the increased silica fume content by5.98 ~ 73.68%, and increases by 0.26~19.32% with the increase of added fiber content; the abrasion resistance capability of wet and dry concrete specimens increases with the increase of percentage of sand, added silica fume and fiber contents. (4) When the ultrasonic pulse velocity higher than about 4600 m/s, dynamic modulus of elasticity higher than about 36 GPa, shear modulus higher than about 13.5 GPa, compressive strength higher than about 45 MPa and modulus of rupture higher than 6.2 MPa, the abrasion percentage of concrete specimens keeps at the values between 3.1 ~ 3.5%.concrete Concrete abrasion loss rate is decreases when the ultrasonic pulse velocity, dynamic of elastic modulus, dynamic of shear modulus, compressive strength and bending strength increases.
