Learn More### Measuring Compressive Strength| Concrete Construction Magazine

ASTM C39, Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens, specifies that the loading rate fall within 0.14 to 0.34 MPa/sec (20 to 50 psi/sec). On average, the compressive strength of cylinders tested at the high load rate limit will be 3% greater than cylinders tested at the low load rate limit.

Learn More### Concrete Compressive Strength - an overview

The concrete compressive strength f c and the modulus of elasticity E c were tested according to the Australian Standards AS 1012.9 (1999) and AS 1012.17 (1997), respectively, using a servo-hydraulic testing machine with a range of 3000 kN. In order to obtain more accurate experimental data, the concrete compressive strength and modulus of elasticity were tested on the day of the beam test

Learn More### Why Concrete Has Good Compressive Strength But Bad Tensile

Concrete has tremendous compressive strength, so to make it sturdier, engineers add steel bars inside concrete structures. This adds to the tensile strength of the concrete structure to make it a strapping, robust building. Notice the steel rods. They impart tensile strength to the concrete structure.

Different modeling techniques like multiple linear regression, decision tree, and random forest, etc. will be used for predicting the concrete compressive strength. A comparative analysis will be performed to identify the best model for our prediction in terms of accuracy. The best model will be helpful for civil engineers in choosing the appropriate concrete for bridges, houses construction.
