Concrete Mix Design Example . 1.1 mix design concrete mix design is the process of selecting the proportions of cement, water, fine and coarse aggregates and, if they are to be used, additions and admixtures to produce an economical concrete mix. From is 456 2000 maximum w/c ratio is 0.45, but based on experience (adopt it given w/c ratio vs.
Concrete Mix Design, Procedure and Its Advantages Civil Solution from civilsolution.in
Size of uncrushed aggregate to be used = 20 mm. Method • target mean strength= 35 n/mm2 • maximum size of aggregate = 20 mm • w/c ratio = 0.43 • water required per m3 of concrete= 190 kg • sand as percentage of total aggregate by absolute volume = 35 % • entrapped air in concrete= 2 % • sp gravity of cement= 3.15. Range of normal weight concrete is from 2,200 kg/m3 to 2,400 kg/m3 10.
Concrete Mix Design, Procedure and Its Advantages Civil Solution
• slump value of concrete should be selected based on scope of compaction during casting, for example, to make flowing concrete slump should be in the W/c ratio vs comprresive strength. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of. For a concrete sample mix containing 90 pounds of coarse aggregate with an sg of 2.75, 60 pounds of fine aggregate with an sg of 2.61, 25 pounds of cement with an sg of 3.15 and 12 pounds of water (with an sg of 1), the av is computed as follows:
