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
Q1. The design of a concrete mix requires 1173 kg/m³ of gravel in dry condition, 582 kg/m³ of sand in dry condition, and 157 kg/m³ of free water. The gravel available at the job site has a moisture content of 0.8% and absorption of 1.5%, and the available sand has a moisture content of 1.1% and absorption of 1.3%. What are the masses of gravel, sand, and water per cubic meter that should be used at the job site?
