摘 ? 要：研究了不同粉煤灰取代率的再生混凝土在硫酸鹽-凍融耦合環境下的質量損失率和相對動彈性模量的變化規律，并采用兩參數Weibull函數建立了壽命預測模型。結果表明，在硫酸鹽-凍融耦合環境下，隨著凍融次數的增加，各組試件的相對動彈性模量和質量均呈現先上升后下降的趨勢；當粉煤灰取代率為30%時，試件在硫酸鹽-凍融耦合環境下的耐久性最優，最多可經受362次硫酸鹽-凍融循環后才會失效。 Abstract: The mass loss rate and relative dynamic elastic modulus of recycled concrete with different replacement rate of fly ash under sulfate-freeze-thaw coupling environment were studied, and the life prediction model was established by using two-parameter weibull function. The results show that the relative dynamic elastic modulus and mass of each group of specimens increase first, and then decrease with the increase of freeze-thaw times under sulfate-freeze-thaw coupling environment. When the replacement rate of fly ash is 30%, the durability of specimens under sulfate-freeze-thaw coupling environment is the strongest, and it will fail only after 362 sulfate-freeze-thaw cycles at most.

摘 ? 要：研究了陶粒摻量對透水混凝土孔隙率、抗壓強度、透水性能及抗凍性能的影響。結果表明，隨著陶粒摻量的增加，透水混凝土的連續孔隙率、透水系數逐漸增大，抗壓強度逐漸減小。當陶粒摻量為30％時，透水系數最大，達到了3.10 mm/s，此時抗壓強度為11.7 MPa。經過25次凍融循環后，當陶粒摻量達25%以上時，透水混凝土發生凍融破壞。 Abstract: The influence of ceramic content on the measured porosity, mechanical properties, water permeability and frost resistance of pervious concrete was studied. The results show that the measured porosity and permeability coefficient of pervious concrete increase gradually with the increase of ceramic content, while the compressive strength decreases. when the ceramic content is 30%, the water permeability coefficient is the largest, reaching 3.10 mm/s, and the compressive strength is 11.7 MPa. After 25 freeze-thaw cycles, when the ceramic content is 25% or more, the pervious concrete is damaged by freezing and thawing.
