Concrete Strength Calculator
Calculate concrete compressive strength, required mix ratios, and material quantities for your construction projects. Determine the optimal concrete mix for structural requirements.
Step 1: Mix Design Parameters
Understanding Concrete Strength
Compressive strength is the primary measure of concrete quality. Standard concrete ranges from 20-40 MPa, while high-strength concrete can exceed 60 MPa. The water-cement ratio significantly affects strength and durability.
Step 2: Project Requirements
About Concrete Mix Design
A typical concrete mix contains cement, aggregates (sand and gravel), and water. Admixtures may be added for specific properties. Proper mix design ensures strength, durability, and workability for your specific application.

Concrete Strength Formula
Abrams’ Law: f_c = k1 / (k2^(w/c))
Concrete compressive strength is inversely proportional to the water-cement ratio. Lower w/c ratios yield higher strength but reduce workability. Typical ratios range from 0.35 (high-strength) to 0.70 (low-strength).
