本試驗擬先期於試驗室內建置同料源、不同水灰比(w/cm)之混凝土配比設計，求得混凝土模製圓柱試體之抗壓強度、齡期與超音波速以及90天齡期之水灰比、硬化混凝土水泥含量與實際水泥用量關係曲線。 擇某工程所規定之同料源混凝土等級，澆置混凝土結構體，並求得模製圓柱試體之抗壓強度、齡期與超音波速以及硬化混凝土水泥含量，結構體超音波與齡期等彼此相關性迴歸曲線後，藉此對結構體作長期重覆性超音波量測來評估結構體混凝土強度；以及檢測硬化混凝土水泥含量來評估預拌廠品質控制水準與均勻性，進而擬訂定相關檢測規範之可行性試驗。 This experiment plan draw up in advance in laboratory inside build put with same materical sources each's different cement-water ratio (w/ cm) match than concrete designer, seek concrete mold column body compressive strength, age with Ultrasonic 's wave velocity and 90 day age cement-water ratio, hardened concrete cement content and practical cement quantity. Select certain's engineering stipulation with same materical source concrete grade, pour put concrete 's structure, and seek concrete mold column body compressive strength, age with Ultrasonic 's wave velocity and hardened concrete cement's content, structure's Ultrasonic 's wave velocity with age for each other's relativity regression curve behind, herewith to structure do long-term repeatability's Ultrasonic 's wave velocity measure evaluate structure concrete intension; and checkout hardened concrete cement content evaluate in advance re-mix factory quality control lever and equality , and furthur draw up relative to checkout normalize feasibility experiment.
