In this dissertation, the engineering properties of the nano - al2o3 and nano - tio2 reinforced cement - stabilized soil are respectively studied through the laboratory experiments. based on testing data, the unconfined compressive strength ( ucs ) of nanometerial - al2o3 reinforced cement - stabilized soil ( narcss ) is firstly analyzed in different nanomaterial mixing ratio, cement mixing ratio, curing - period, water content, w / c ratio, etc., and then the stress - strain relationship of narcss is given. the variation of the ucs of nanometerial - tio2 reinforced cement - stabilized soil ( ntrcss ) is also given in different nanometerial mixing ratio and curing period
根據試驗結果，首先分析了納米材料al _ 2o _ 3摻入比、齡期、土樣含水量、水灰比等對摻納米材料al _ 2o _ 3水泥土強度的影響，並給出其應力應變關系（本構關系）和一定條件下的最佳配比；其次，分析了納米材料tio _ 2摻入比、齡期等對摻納米材料tio _ 2水泥土強度的影響；最後，通過比較前人的研究成果，對分別摻入納米材料al _ 2o _ 3 、納米材料tio _ 2及納米材料sio _ （ 2 - x ）的水泥土強度進行了對比分析。 -
Adopting fd - 1 admixture, c50 concrete can be obtained, which has excellent adaptability for environment temperature ? 5 c ; self - shrinkage of concrete is inevitable, and its variation tendency based on w / c and hydration age, fd - 1 has wonderful inhibition for self - shrinkage, and meanwhile anti - friction property can be promoted
