Hexagonal Boron Nitride Reinforced Multifunctional Concrete for Transportation Infrastructure.

This project will develop and test the properties and performance of concrete reinforced with hexagonal boron nitride (hBN) for use in highway infrastructure. Work in Stage 1 will focus on the synthesis and laboratory testing of hBN/Concrete Cylinders. Solution-based processing for synthesis, exfoliation, hydrolysis and mixing of ultra-thin hBN nanosheets in concrete will be developed. Optimum synthesis conditions and parameters will be identified, including temperature, sonication power, time, and hBN weight percentage. This synthesis protocol will be followed by and fine-tuned using American Society for Testing and Materials/American Association of State Highway and Transportation Officials (ASTM/AASHTO) Testing Standards for concrete cylinders. Various key properties will be measured and a product datasheet elucidating the product features and performance enhancement will be prepared. The mechanical testing will include compressive and tensile strengths, ductility, toughness, and elastic modulus using standard ASTM/AASHTO tests and procedures. Four-point flexural bending test to obtain the modulus of rupture (ASTM C1609) will also be done. Durability, alkali silica reactions (ASR), freeze-thaw, and abrasion tests will also be performed using standard ASTM and AASHTO tests/procedures. Work in Stage 2 will focus on a pilot test study on the practicability of producing hBN/cement concrete product and to monitor its performance in service in collaboration with Texas Department of Transportation (DOT) (Houston District) on a small portion of a road or a highway. The hBN/concrete will be reinforced by conventional steel rebars and placed adjacent to a control concrete (made of conventional concrete with the same dimensions and conditions). The hBN and control reinforced concrete will be monitored in-service for a period of one year and tested according to Texas DOT and ASTM procedures. The performance will be evaluated with regard to durability and mechanical and other properties and compared with that of the control sample. Stage 2 Work will provide important in-service data and demonstrate pilot-test performance and long-term behavior to help facilitate larger-scale implementation and commercialization of the new product.
