What is the value of β1 if the compressive strength of concrete is 34 MPa? Round of your answer to two decimal places.

Give me right solution urgent

From the following figure, List down the concrete matenals by any method using class "A" concrete.

Four standard concrete cylinders of 6-inchdiameter cross section were tested underuniformly increasing axial compressive loads 28days after casting concrete. The maximummeasured loads were 121,000 lbs, 116,700 lbs,128,800 lbs, and 119,100 lbs. What is the averagecompressive strength of this concrete in ksi?

Given fc' = 35 MPa, solve for the modulus of elasticity of concrete a. 27,800.00 MPa b. 27,805.57 MPa c. 200,000.00 MPa d. None of the above If fc'= 42 MPa, solve for B. a. 0.65 b. 0.75 C. 0.85
