Abstract
To address the scarcity of coarse aggregate resources for vegetated concrete in coastal regions,this paper proposes the use of artificial granulation technology to prepare sea sand granulated coarse aggregate vegetated con-crete(SGVC)by reconstituting fine-grained sea sand into appropriately graded coarse aggregates.The effects of po-rosity on both the engineering properties and vegetation performance of SGVC were systematically investigated.The results indicate that at a water-to-cement ratio of 0.26 and a porosity of 25%,the permeability coefficient of SGVC reaches 12.0 mm/s,while the 28d compressive strength attains 11.8 MPa.Under these conditions,Puccinellia dis-tans exhibited optimal growth performance:the 28d vegetation coverage rate reached 90%with a plant height of 115 mm,and the 42d root length reached 146mm.This study provides a new type of vegetated concrete material that can be locally sourced and applied in coastal slope protection projects.关键词
