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 section of 4 in. * 4 in. and a span of 12 in. The third-point loading flexure strength test was performed on each beam after 7 days of curing. The loads at failure of the beams without admixture were 6044, 5071, and 5934 lb, while the loads at failure of beams with admixture were 7299, 7305, and 6983. Determine:a. The modulus of rupture of each beam in psi.b. The average moduli of rupture of the beams without and with admixture.c. The percent of increase of the average modulus of rupture due to adding the admixture.

We require a mix with a mean 28-day compressive strength of 40 MPa the size of the member and the spacing of the reinforcement require a slump of 45 mm and a maximum size of aggregate of 28 mm. Portland cement type I is used with specific gravity of 3.15, dry-rodded unit weight of coarse aggregate 1750 kg/m³ and bulk specific gravity (SSD) of 2.55. The fineness modulus of fine aggregate is 2.8 and bulk specific gravity (SSD) of 2.5 ,No air entrainment is required. Neglect water absorption and moisture content of both aggregates. The aggregates conform to the ASTM C33-84 requirements for grading. Estimate the quantity of (cement, fine aggregate, coarse aggregate and water) for 1m³ concrete.
Working on major construction project that requires considerable amounts of concrete to be used,you are asked to design a concrete mix following the BRE methodology. All the necessary tables forthis can be found in the Appendix. The concrete mix specifications are:o Characteristic compressive strength of 35 N/mm 2 at 28 days.o Failure rate of 2%o Previous control data yielded a standard deviation of 10 N/mm 2o CEM-I 42.5o Air-entraining is not requiredo Maximum water to cement ratio 0.40o Minimum cement content 390 kg/m 3o Required slump 50 mmo Coarse aggregate: Crushed maximum size 20mmo Fine aggregate: Uncrushed with 90% passing 600 μm sieveo Relative density of aggregates: 2.5o Coarse aggregate has 4% moistureo Fine aggregate is dry and has 1.2% absorption.o Volume of the required trial mix: 0.090 m 3Following the BRE step-by-step process estimate the water content of the mix estimate the content of aggregates, provide the estimated mix quantities
