The Kansas City Metro Materials Board is a cooperative
effort of public works organizations in the KC Metro area. The KCMMB goal is to standardize material specifications
for durable concrete on public works projects and simplify the approval process with the assistance of this
web site. This concrete alternative focuses on Life-Cycle costs rather than first costs.
The specification highlights include requirements for aggregate, cement, and mix proportions, which
are intended to improve the durability of concrete. Click the
KCMMB Specification button for a full text
display. This is a culmination of over three years of research by municipalities to discover and prevent the
causes of premature cracking and deterioration of pavement, sidewalks, curbs, and storm drainage inlets.

county projects constructed after April 1, 2001. Click on the
KCMMB Members button to view the current list

As a member, you may click the Concrete Mix Design button for a list of approved concrete mixes by KC Metro
concrete suppliers. This is detailed proprietary information on concrete mixes and is available only to KCMMB
Members in the secure area requiring the use of a password. This web site provides a current database for quick
reference of mixes and assists field inspectors with verification guidelines for KCMMB concrete delivered to a
project site.
