| Study on application of strength curve based on ultrasonic rebound combined method to 1 700～1 900 density grade light aggregate concrete |
| 摘要 |
| 針對1 700～1 900密度等級輕集料混凝土，進行了系統(tǒng)的超聲回彈綜合法測強曲線的研究。試驗結(jié)果表明，CECS 02：2005《超聲回彈綜合法檢測混凝土強度技術(shù)規(guī)程》中無論是卵石還是碎石的國家統(tǒng)一測強曲線均不適用輕集料混凝土，其相對標準誤差超過誤差范圍要求；建立了1 700～1 9 |
