【摘要】：水滑石(LDHs)具有層間陰離子可交換性和結(jié)構(gòu)記憶性的特點(diǎn),可利用外摻水滑石(LDHs)吸附侵入水泥石中的二氧化碳,從而提高水泥基的抗碳化性能。通過X射線衍射可以觀察煅燒水滑石(LDOs)在碳化環(huán)境下的結(jié)構(gòu)重建情況,以及摻煅燒水滑石(LDOs)水泥砂漿的抗碳化行為。試驗(yàn)表明:500℃煅燒后的水滑石具備較強(qiáng)的結(jié)構(gòu)重建能力,可在水泥水化環(huán)境下吸附二氧化碳并有效提高水泥基抗碳化性能。
[Abstract]:Hydrotalcite (LDHs) has the characteristics of interlayer anionic exchangeability and structural memory. It can be used to adsorb carbon dioxide in cement stone by adding water talc (LDHs), thus improving the carbonization resistance of cement base. The structure reconstruction of calcined hydrotalcite (LDOs) in carbonized environment and the carbonation resistance of calcined hydrotalcite (LDOs) cement mortar can be observed by X-ray diffraction. The experimental results show that the calcined hydrotalcite at 500 鈩，
