New Catchment Surface Materials for Rainwater Harvesting and Utilization
Abstract：The rapid development of rainwater harvesting technology,has led to renewed interest in improving catchment surface performance,as the first link in the rainwater harvesting system.The proposed modified concrete mixtures should be further studied and undergo rigorous field testing.The results of this study showed that,①Polypropylene fibers are ideal for concrete admixtures,as these can enhance the strength of catchments areas,improve the concrete performance,strength grade,and frost resistance.②To reduce costs of catchment surface construction,the ideal thickness is 3.0 cm,as this provides the required bearing strength and frost resistance as well as ensuring a high runoff coefficient.③The two best options for concrete catchment surface area materials are,C15 ＋ polypropylene fibers and C20 concrete.These concrete types compare favorably with conventional concrete catchments and their widespread application is recommended in the future.
