透明混凝土的透光性能研究

Study on transmission performance of transparent concrete

透明混凝土作为一种新型功能材料,是由大量的光纤或透明树脂等透光材料与普通混凝土制成,具有高透明度,可透过太阳光的特点,为了便于透明混凝土材料进一步的推广应用,达到节省光纤和混凝土材料、提高分析效率、为其透光性能的分析提供可靠数据的目的,本文结合透明混凝土的透光性能实验,利用ZEMAX对透明混凝土透光实验进行仿真模拟,建立了用于预测光纤透光效能的评估预测模型,通过分析总结出透明混凝土的透光性能评价指标和计算方法以及透光率与光纤类型和空间分布的关系,并得出结论,透明混凝土的透光性能与光纤排布密度、光纤的特性以及试块端面的抛光程度有关,透光率与光纤间距是单调递减的指数函数关系,与光纤半径是单调递增的指数函数关系。

Transparent concrete,as a new style functional material,is made of a large number of fibers or trans-parent resin with ordinary concrete,with the characteristics of high transparency thus allowing the sunlight to penetrate through.In order to facilitate further application of transparency concrete materials and achieve the purpose of saving the fiber and concrete materials,improving the efficiency of the analysis and providing light performance analysis of reliable data,the paper established a evaluation and forecast model to assess transparent performance of transparent concrete by means of combining with the light performance test of transparent con-crete and using ZEMAX for simulation of the test.It was found that light transmittance had the relationship with optical fiber type and its spatial distribution and the evaluation index and calculation method of light per-formance were summed up.Besides,the results show that the light performance has the relationship with the density of optical fiber configuration,fiber properties as well as the block surface polishing degree.Light trans-mittance through the fiber spacing span is monotonically decreasing exponential function,and the fiber radius is monotonically increasing exponential function.
