Description

Technical Field

[0002] Grouting material is a product specially used for grouting construction of post-tensioned prestressed pipes. It is optimized and formulated from a variety of high-quality cement-based materials and a variety of organic and inorganic materials such as expansion agents and water reducers. It has excellent fluidity, stable slurry, good filling degree, adjustable setting time, no shrinkage, micro-expansion, high strength, and does not contain harmful substances to steel bars. During the production of grouting material, if the grouting material contains impurities, uneven grouting and empty slurry will occur, which will cause bridges to collapse and endanger people's travel safety.
