- You are working on a concrete mix design that requires each cubic yard ofconcrete to have 0.45 water–cement ratio, 1165 kg/m3 of dry gravel, 4% air content, and 335 kg/m3 of cement. The available gravel has a specific grav-ity of Ggravel = 2.7, a moisture content of 1.6%, and absorption of 2.4%. The available sand has a specific gravity of Gsand = 2.5, a moisture content of4.8%, and absorption of 1.5%. For each cubic meter of concrete needed onthe job, calculate the mass of cement, moist gravel, moist sand, and waterthat should be added to the batch. Summarize and total the mix design whenfinished (don’t include air entrainer in summary).a) What is pozzolanic material; what benefits can be achieved by using Pozzolana with cement in concrete? b) For what purpose we use Ultrasonic Pulse velocity test? Also classify the quality of concrete if Ultrasonic Pulse velocity is 3.0km/sec? SIR, PLS GIVE ME PROPER AND CORRECT ANSWER WITH FULL DETAILS. THANKS SUBJECT: CONCRETE TECHNOLOGYQ-1: The table below lists the properties of five different pozzolans: Ground blastfurnace slag, Silica Fume, Class F fly ash, Class C fly ash, Metakaolin. Determine which one is which pozzolan? Determine which ones are self-cementing? Explain why?
- As an engineer would you recommend the use of Fly ash instead of Portland cement, explain what benefit will this have on Concrete.You are working on a concrete mix design that requires each cubic yard ofconcrete to have 0.45 water–cement ratio, 1963 lb/yd3of dry gravel, 4% aircontent, and 565 lb/yd3of cement. The available gravel has a specific gravity of Ggravel = 2.7, a moisture content of 1.6%, and absorption of 2.4%. Theavailable sand has a specific gravity of Gsand = 2.5, a moisture content of4.8%, and absorption of 1.5%. For each cubic yard of concrete needed onthe job, calculate the weights of cement, moist gravel, moist sand, and waterthat should be added to the batch. Summarize and total the mix design whenfinished (don’t include air entrainer in summary)Two batches of cement mortar with properties as shown in Table P6.18. Ifmortar cubes are made from these batches, which batch do you expect to havelarger compressive strength? Why?
