Chapter 19 - Concrete
Section 1905 - CONCRETE QUALITY, MIXING AND PLACING
Subsection 1905.1 - General
Current through Register 1531, September 27, 2024
The required strength and durability of concrete shall be determined by compliance with the proportioning, testing, mixing and placing provisions of Sections 1905.1.1 through 1905.13.
1905.1.1 Strength. Concrete shall be proportioned to provide an average compressive strength as prescribed in Section 1905.3 and shall satisfy the durability criteria of Section 1904. Concrete shall be produced to minimize the frequency of strengths below f c as prescribed in Section 1905.6.3. For concrete designed and constructed in accordance with this chapter, f c shall not be less than 2,500 psi (17.22 MPa). No maximum specified compressive strength shall apply unless restricted by a specific provision of this code or ACI 318.
