### 3 Properties of Concrete The University of Memphis

Concrete has almost no tensile strength usually measured to be about 10 to 15% of its compressive strength and for this reason it is almost never used without some form of reinforcing Its compressive strength depends upon many factors including the quality and proportions of the ingredients and the curing environment

### Tests on Concrete Concrete Slump Test Compression Test

The strength is measured in Megapascals MPa and is commonly specified as a characteristic strength of concrete measured at 28 days after mixing The compressive strength of concrete is a measure of the concrete's ability to resist loads which tend to crush it

### Standards for 7-day and 28-day strength test results

According to section 19 2 1 3 of ACI 318-14 the specified compressive strength shall be based on the 28-day test results unless otherwise specified in the construction documents 3- or 7-day test results are used to monitor early strength gain especially when high early-strength concrete is used

### How to Evaluate Compressive Strength of Concrete FPrimeC

For existing structures compression test is done on drilled cores to evaluate the compressive strength of concrete A larger number of core samples should be drilled within concrete in different positions in order to evaluate the compressive strength with good precision
