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. The concrete mixspecifications are:o Characteristic compressive strength of 50 N/mm 2 at 7 days.o Failure rate of 2%o Previous control data yielded a standard deviation of 5 N/mm 2o CEM-I 52.5o Air-entraining is not requiredo Required slump 120 mmo Coarse aggregate: Crushed maximum size 10mmo Fine aggregate: Uncrushed with 45% passing 600 μm sieveo Relative density of aggregates: 2.7o Coarse aggregate has 4% moistureo Fine aggregate is dry and has 1.2% absorption.o Volume of the required trial mix: 0.120 m3 Create the mix design and state what actions and recommenations you would do if trial produced a result with a mean compressive strength of 64 MPa at 7 days and the slump was 80mm.
A mix design requires 1160 kg/m3 of coarse aggregate (in dry condition), 599 kg/m3of fine aggregate (in dry condition) and 148 kg/m3 of water. The absorption capacityof the coarse aggregate is 0.4 % while the moisture content is 1.5%. The absorptioncapacity of the fine aggregate is 0.4 % while the moisture content is 4%. Pleaseanswer the following questions based on information given. a. What is the amount of Moist Coarse Aggregate? b. What is the amount of SSD Fine Aggregate? c. What is the amount of Moist Fine Aggregate? d. What is the amount of water after adjusting for moisture?
