Researchers have developed a novel type of sustainable building material that combines the strengths of bamboo and phosphogypsum, a waste product from the fertilizer industry. These round bamboo-fiber reinforced phosphogypsum composite short columns offer superior mechanical properties and ductility, paving the way for more eco-friendly construction practices. This breakthrough research not only promotes the use of renewable materials but also tackles the challenge of waste management, showcasing the potential for transforming industrial byproducts into valuable building components.

Meanwhile, phosphogypsum, a byproduct of the phosphate fertilizer industry, poses a significant environmental challenge due to its large-scale accumulation. By combining these two materials, the researchers have developed a unique composite that can capitalize on the strengths of both while addressing the issue of waste management.</p>

<p><h3>Exploring the Mechanical Properties</h3>
</p>
<p>The researchers conducted a series of axial compression tests on 20 different short column specimens, including pure bamboo columns, bamboo columns filled with phosphogypsum, and bamboo columns with phosphogypsum both inside and outside. The results reveal some fascinating insights:</p>
<p>– The presence of <b>bamboo nodes and hose hoops</b> can improve the bearing capacity, initial stiffness, and ductility of the columns.<br />
– The <b>larger the diameter and wall thickness of the bamboo tube</b>, the better the mechanical properties of the short columns.<br />
– The <b>bearing capacity and initial stiffness</b> of the composite short columns are significantly higher than those of pure bamboo columns.<br />
– The <b>ductility</b> of the bamboo columns with phosphogypsum outside is notably superior to that of pure bamboo columns.</p>

<p><h3>Finite Element Analysis and Theoretical Calculations</h3>
</p>
<p>To further understand the behavior of these composite short columns, the researchers conducted finite element analysis using ABAQUS software. The simulation results closely matched the experimental findings, validating the accuracy of the approach.</p>
<p>Additionally, the researchers developed a theoretical calculation method to determine the bearing capacity of the short columns. This method takes into account the <b>strength reduction coefficient, the bamboo node effect coefficient, and the constraint effect</b>, providing a reliable way to predict the performance of these innovative building materials.</p>
