【摘要】：水滑石(LDHs)具有层间阴离子可交换性和结构记忆性的特点,可利用外掺水滑石(LDHs)吸附侵入水泥石中的二氧化碳,从而提高水泥基的抗碳化性能。通过X射线衍射可以观察煅烧水滑石(LDOs)在碳化环境下的结构重建情况,以及掺煅烧水滑石(LDOs)水泥砂浆的抗碳化行为。试验表明:500℃煅烧后的水滑石具备较强的结构重建能力,可在水泥水化环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，
