4000 PSI

4000 PSI 3/8" RK 60/40 is a high-strength concrete mix with a design strength of 4000 PSI and 3/8-inch rock aggregate, using a 60/40 sand-to-gravel ratio. This mix is engineered for applications requiring superior durability and load-bearing capacity, including driveways, commercial slabs, foundations, and municipal construction projects.

With enhanced strength and performance, 4000 PSI concrete is suitable for heavy-duty surfaces and structures that demand long-term durability and resistance to mechanical stress. Compliance with California construction standards ensures consistent quality and structural reliability.
