A Study on the Pore and Strength Characteristics of an Eco-Friendly Sprayed Ultra High Performance Concrete with Manufactured Sand
Conventional shotcrete systems face critical limitations in adverse geological environments, including a delayed strength development (<5 MPa at 3 h), excessive rebounds (15–25%), and permeable macropore networks (>50 μm), often resulting in support failure for deeply buried tunnels. To addres...
