Computer Simulation of 3-D-Printed Polymer Concrete Tank

Presented By: Mahmoud Reda Taha, University of New Mexico Description: Polymer concrete has been widely used for producing architectural façade, underground utilities, wastewater tanks, manholes, and other precast elements. Polymer concrete is distinguished with high compressive and tensile capacities and superior durability. We have developed and tested a new polymer concrete mixture and showed its efficiency for producing 3D-printed polymer concrete elements. In this presentation, we report developing and validating a finite element model to simulate the printing process of 3D-printed polymer concrete tank. An experimental program was conducted to extract the necessary mechanical characterization of green 3D-printed polymer concrete, including compressive strength, shear strength, modulus of elasticity, and internal friction angle. These mechanical characteristics were used to develop a finite element model to simulate polymer concrete's printing process. The model is validated and used to predict the stresses developed in the polymer concrete tank walls during printing.
