Due to the present moisture, it is expected that the concrete shall be non-aerated (Non AE) with a 28 day compressive strength of 3,000 psi for slabs and 4,000 psi for beams and columns.

To evaluate the effect of a certain admixture on the flexure strength of concrete, two mixes were prepared, one without admixture and one with admixture. Three beams were prepared of each mix. All the beams had a cross sectionof 0.15 m by 0.15 m and a span of 0.45 m. The third-point loading flexurestrength test was performed on each beam after 7 days of curing. The loads atfailure of the beams without admixture were 32.8, 34.5, and 31.7 kN, whilethe loads at failure of beams with admixture were 39.4, 35.6, and 35.0 kN.Determine:a.
