Concrete Charts & Reference Tables
Quick-reference tables with context, units, assumptions, and links to deeper guidance.
Reference charts are useful when they summarize data honestly. They become dangerous when a planning number is presented as a code requirement. Every table here labels whether a value is a conversion, a nominal product estimate, a qualitative planning reference, or a pointer to a governing standard.
Concrete Volume Conversion Chart
Quick conversions among cubic inches, cubic feet, cubic yards, and common slab-area relationships.
Bagged Concrete Yield Planning Chart
Example nominal yields and how to use the manufacturer label for accurate bag counts.
U.S. Rebar Size, Diameter & Weight Chart
Common U.S. reinforcing-bar size numbers with nominal diameter and approximate unit weight.
Slab Joint Spacing Planning Chart
A thickness-based preliminary spacing check using the commonly cited 24–36× slab-thickness concept.
Slope & Drainage Conversion Chart
Convert inches of fall per foot to percent grade and approximate ratio.
Common Fresh & Hardened Concrete Test Methods
A field-oriented map of common ASTM concrete tests and what each measurement tells you.
