Abstract:
The objective of this paper is to study the mechanical properties of coral aggregate seawater concrete (CASC) and sisal fiber coral aggregate seawater concrete (SFCASC) under monotonic load. Based on the theory of rich slurry concrete, the authors prepared a CASC with compressive strength greater than 70 MPa. Uniaxial compression testing was carried out by using an electro-hydraulic servo device. The results showed that the brittleness of CASC was greater than that of ordinary portland concrete (OPC). Sisal fiber can improve its brittleness obviously, while the increase in compressive strength is not significant—SFCASC is only 4.6% higher than CASC. The mechanism of CASC interface enhancement was analyzed from the microscopic perspective. A mathematical model composed of piecewise curvilinear functions was formulated to describe the mechanical properties of CASC. The experimental results validated the model, and showed that the model can better describe the monotonic stress-strain relationship of CASC.
