Novel bridge post-tensioned prestressed tunnel grouting material and preparation method thereof
The invention belongs to the technical field of bridge construction materials and relates to a novel bridge post-tensioned prestressed tunnel grouting material and a preparation method thereof. The novel bridge post-tensioned prestressed tunnel grouting material comprises 55-85% of portland cement clinker, 5-25% of ore powder and 5-25% of a grouting agent. The novel bridge post-tensioned prestressed tunnel grouting material is prepared by simple processes, does not contain gypsum, fly ash, vulcanic ash and light substances of a grouting agent, does not produce laitance at the highest point of a curve pipe under pressure in bridge post-tensioned prestressed tunnel grouting and in a voltage stabilization period and in a hardening period, has high strength, does not cause layering after secondary supplied grouting liquid hardening in grouting liquid supply treatment, effectively prevents prestressed strand corrosion and fracture, produces great influence on bridge structure safety and endurance and has a wide popularization meaning.
