Topology Optimization Based Additive Construction Presented by: Islam Mantawy, Rowan University
Presentation details
Structural Performance of Additively Constructed Concrete (ACI Spring 2024, New Orleans, LA) For decades, concrete structures are constructed using cementitious based materials using conventional methods through formworks (either cast-in-place or precast). Concrete with sufficient slump is needed to fill up the formworks. This approach results in significant material wastage (where the material is placed at areas with low to very low stresses) and increases carbon footprint. Additive construction provides unique opportunities to build form-free structural elements with complex geometry which enable topology and structural optimization. This presentation include 1) Development of 3D-printed versions of concrete with lower carbon footprint; 2) utilization of advanced modelling techniques for topology and structural optimization of structural elements; 3) utilization of strut-and-tie methods for topology and structural optimization, and 4) small scale and large scale additive construction for optimized structural beam. The presentation will conclude with detailed comparison between conventionally constructed beam and additively constructed beam in terms of materials saving and emission reduction.

High Molecular Weight Methacrylate Acrylic Resin for Sealing Concrete Bridge Deck Cracks and Surfaces Presented by: Michael Stenko, Transpo Industries
Honoring Michael M. Sprinkel - A Career of Concrete Preservation (ACI Spring 2024, New Orleans, LA) High Molecular Weight Methacrylate resins have seen increased use in a variety of applications. For sealing cracks in horizontal concrete substrates, the materials extremely low viscosity and extended gel time allows it to penetrate deep into cracks sealing them from water penetration. The development of handheld low pressure injection equipment makes it possible to seal cracks on horizontal as well as vertical concrete surfaces. Additional High Molecular Weight Methacrylate resin formulations with thixotropic properties makes it possible to seal cracks on vertical and overhead surfaces. The presentation will discuss the different application methods, equipment, and material physical properties.
