Investigations on the Preparation of Newly Recycled Composite Wood Keel and Its Mechanical Properties
The keel system is an important link of turnover material control in engineering construction.Recently,the existing keel system has the disadvantages of a low turnover rate,serious wood waste,etc.In this study,a new type of recycled composite wooden square keel was prepared using construction waste wood and advanced extrusion coating technology as well as testing their related mechanical properties.The test results show that the new composite keel of 40 mm×70 mm had higher ductility,which was more suitable for engineering applications.Its mechanical properties covered 0.71 MPa shear strength,13.16 MPa compressive strength,and 941.06 MPa elastic modulus.The moment of inertia and resistance torque calculation were1.24×106 mm4 and3.50×104 mm3,and the bending capacity was 22.33 MPa.Compared with the traditional wooden square keel,the newly recycled composite wood keel had better elastic modulus and flexural strength.The new composite keel had the advantages of solid waste resources utilization,low cost,and standardized preparation,which can lay a foundation for the sustainable development of the keel system in engineering construction.
