AI Technical Summary
Existing technologies struggle to effectively control the shrinkage of ultra-high performance concrete (UHPC) while meeting the actual mechanical performance requirements of engineering projects, especially the damage caused by early shrinkage issues such as cracks and steel corrosion.
By employing modified porous silica, nano-expansives, nano-calcium silicate crystal nuclei, and hydration kinetic regulators, the affinity of the material for water is enhanced and humidity stability is increased by optimizing the pore structure and surface modification, combined with the volume expansion compound of the nano-expansives, thus forming a micro-nano structure to optimize the pore structure.
It effectively reduces the early shrinkage of UHPC and improves the mechanical properties of concrete, including compressive strength and flexural strength, to meet the actual needs of engineering projects.
