Latest technical standards for grout materials for wind power

1. The size and grain size requirements of grouting materials: coarse materials should be between 16 and 65 mm, and fine materials should be between 0.075 and 2 mm.

2. Quality requirements for wind power grouting materials: compressive strength ≥15N/mm2, water absorption ≤4%, elasticity and toughness ≥50%, wind pressure resistance ≥2.0kPa, Surface adhesion ≥80%, density is normal.
