2) water reducing admixture ( including superplasticizer or high range water reducer) can be used to achieve the required workability with lesss amount of water. what is the mechanism of water reducer?

Civil Engineering materials class

Water contained in a piston-cylinder assembly as shown in the Figure below, initially at 1.5 ??? and a quality of 20%, is heated at a constant pressure until the piston hits the stops. Heating then continues until the water is saturated vapor. Show the processes of the water in series on a sketch of the ?-? diagram. For the overall process of the water, evaluate the work and heat transfer, each in ??⁄??. Kinetic and potential effects are negligible. (please show your work)

1. Calculate the future trip distribution based on the (a) uniform (b) average (c) fratar (d) furness growth factor models using the existing trip matrix as presented in table 6.72. The future trip productions and attraction for zone 1, 2, 3 and 4 are (90, 45), (70, 48), (52,82) and (42, 66). Respectively.

Answers for c and d please

A compacted asphalt concrete specimen contains 4.8% asphalt binder by weight of total mix and aggregate blend with blended specific gravity of 2.689. The average bulk density of the compacted specimen is 2.414 g/cm3 . Ignoring absorption of aggregate particles, 1) compute the VTM, VMA, VFA, and D/B of the specimen. 2) Draw the phase diagram of this asphalt mixture.

- Asphalt binder specific gravity, Gb: 1.03

- Passing #200 fine fillers (%): 4.7 %

Part 1: A five-sided closed field traverse has the following distances in feet: AB = 647.25; BC = 203.03; CD = 720.35; and DE = 610.24; and EA = 285.13. The interior angles are as follows (measured as angles to the right): A = 100º 45' 37"; B = 231º 23' 43"; C = 17º 12' 59"; D = 89º 03' 28"; and E = 101º 34' 24". The bearing of AB is S 53º 04' 43" E. Determine the bearings of each side
