Modern concrete is a multi aggregate composed of cement, mineral admixtures, sand, stone, air, water, and additives, and can meet the basic requirements of “high workability, high early strength enhancement, and high durability”.
Modern concrete should include high-performance concrete, high-strength concrete, fluid concrete, pumped concrete, self leveling and self compacting concrete, anti-seepage and crack resistant concrete, underwater pouring concrete, and commercial concrete.
The traditional concrete mix design method based on strength cannot meet the requirements of modern concrete mix design.
