【摘要】：混凝土由于水化溫升的影響,結(jié)構(gòu)內(nèi)部溫度與試驗室標(biāo)準(zhǔn)養(yǎng)護(hù)或同條件養(yǎng)護(hù)下留樣混凝土試塊溫度存在較大差別,因此采用留樣混凝土強度作為實體構(gòu)件的抗壓強度可能存在較大誤差。介紹了采用成熟度理論預(yù)測水下封堵用混凝土抗壓強度的方法。現(xiàn)場結(jié)果表明:與留樣相比,采用成熟度理論預(yù)測混凝土強度能更加準(zhǔn)確地反映混凝土實際抗壓強度。
[Abstract]:Due to the effect of hydration temperature rise, the internal temperature of the concrete structure is different from that of the specimen under the standard curing in laboratory or under the same condition. Therefore, there may be some errors in the compressive strength of concrete retaining concrete. This paper introduces the method of predicting the compressive strength of underwater plugging concrete by using maturity theory. The field results show that the prediction of concrete strength by using maturity theory can more accurately reflect the actual compressive strength of concrete than that of retaining samples.
