    摘 ? 要：利用廢棄PET塑料制備了再生PET塑料骨料（RPA），研究了RPA部分取代天然細骨料（0、10%、20%、30%、40%）對砂漿單軸受壓性能的影響，并建立了摻RPA砂漿的單軸受壓應力-應變本構關系。結果表明：隨著RPA取代率的增加，試件的延性增加，應力-應變曲線上升段和下降段斜率逐漸降低，峰值應力和彈性模量逐漸降低；試件的峰值應變、極限應變和抗壓韌性指數均隨著RPA取代率的增加而增大；建立的摻RPA砂漿單軸受壓本構方程計算結果與試驗結果吻合較好。

Abstract: Recycled PET plastic aggregate(RPA) was prepared from waste PET plastics. The effect of RPA partially replacing natural fine aggregate (0, 10%, 20%, 30%, 40%) on the uniaxial compressive properties of mortar was studied, and the uniaxial compressive stress-strain constitutive relationship of mortar mixed with RPA was established. The results show that with the increase of RPA replacement rate, the ductility of the specimen increases, the slopes of the rising and falling sections of the stress-strain curve gradually decrease, and the peak stress and elastic modulus gradually decrease. The peak strain, ultimate strain and compressive toughness index increase with the increase of RPA replacement rate. The established constitutive equation of the mortar mixed with RPA under uniaxial compression is in good agreement with the experimental results.

（4）隨著RPA取代率的增加，試件的受壓耗能能力逐漸增強，不同取代率RPA砂漿試件的抗壓韌性指數較NC試件提升了19.1%~38.6%。
    
（5）本文建立的不同RPA取代率下砂漿試件的單軸受壓本構關系可較好地描述摻RPA砂漿試件在單軸受壓下的應力和應變發展規律。
