The third-point loading flexure strength test was performed on aIVI ...concrete beam having a cross section of 0.15 m by 0.15 m and a span of 0.45 m. If the load atfailure was 35.7 kN, calculate the flexure strength of the concrete. This normal-weight concretehas an average compressive strength of 20 MPa. What is the estimated flexure strength (hints:use the ACI equation)?

From above figure 2P=35.7 kN P=17.85 kN The expression for maximum moment is given as…

Problem 1: Concrete is required for internal columns of a building. The specified strength is 25 MPa at 28 days and it is required that no more than 1 test result in 20 will fall below the specified strength. The concrete testing history of 50 tests, carried out by the construction company for the same concrete grade, indicated a standard deviation of 3 MPa. The size of the column sections and the spacing of steel require slump of 80 mm and Dmax of 20 mm. The fine aggregate have FM of 2.665, and absorption of 2%, BSG (SSD) of 2.6. The CA have bulk density of 1500kg/m³; absorption of 4% and BSG (SSD) of 2.50. The moisture content for both aggregate is 1%.
