基于高树脂掺量的透光混凝土的砂浆性能研究

Study on Mortar Performance of Transparent Concrete Based on High Resin Content

为了制备高树脂掺量并保持高强度的树脂基透光混凝土,以碱式硫酸镁水泥为胶凝材料,通过测试跳桌流动度、U型仪砂浆通过能力以及试样强度,对不同配比砂浆的性能进行了对比研究。结果表明,砂浆流动度与通过能力的变化规律并不一致,通过能力的测试更能体现树脂基透光混凝土在浇筑时砂浆所受到的阻力情况。通过配合比的优化,成功制备出树脂体积掺量为20%、抗压强度为45.4MPa的树脂基透光混凝土。

In order to prepare resin based transparent concrete with high resin content and maintain high strength,we used basic magnesium sulfate cement as cementitious material,and compared the properties of mortars with different ratios by table jumping fluidity,mortar passing capacity of u-meter and strength.The experimental results show that the change rule of fluidity and passing capacity of mortar is not consistent and the passing capacity test can better reflect the resistance of mortar when resin based transparent concrete is poured.Through the optimization of mixture proportions,the resin based transparent concrete with 20%resin content and 45.4 MPa compressive strength is successfully prepared.
