What is high strength concrete?
Concrete with compressive strength more than 55 MPa is known as high strength concrete.It is used in the construction of bridges, dams. etc.,High strength concrete is produced by adding normal constituents of concrete with admixtures.

How do you calculate target mean strength?
To calculate the target mean strength for concrete, you first determine the desired characteristic strength (fck) based on design requirements. Then, account for a specified margin of safety, typically using a standard deviation from previous test results to establish the target mean strength (fct). The formula commonly used is: Target Mean Strength = fck + 1.64 × standard deviation, where 1.64 corresponds to a 95% confidence level. This ensures that the concrete produced will meet the required strength with a high degree of reliability.
What is tensile strength of concrete?
The tensile strength of concrete is 10% of it's compressive strength.
What is the difference between compressive strength and target strength?
Compressive strength of concrete is defined as the concrete cube of 150 mm x 150 mm x 150 mm with specified proportion with 28 days curing.Target mean strength - In order that not more than the specified proportion of test results are likely to fall below the characteristic strength, the concrete mix has to be designed for a somewhat higher target average compressive strength (fck).__fck = fck + t * swhere ___fck is target average compressive strength at 28 days,fck is a characteristic compressive strength at 28 days ands standard deviationt a statistic, depending upon the accepted proportion of low results and the number of tests.
