2) Two aggregates (Al and A2) were obtained from the field. They were brought to the oven dry condition (OD) and weighed. Data for each of the aggregates is presented in the table below. (Density of water=1g/cm') Table 1. Absorption capacity and moisture content data. A1 A2 Field Weight 600 g 600 g 598.3 g Oven Dry Weight Absorption Capacity (%) 0.6 % 595.3 g 0.7% a) Describe the field moisture state of each aggregate, Al and A2 (i.e. wet, SSD, or air dry). For each sample would you add water or dry the sample to bring it to SSD state? Determine the expected mass of each sample in the SSD state. b) If the bulk volume Al oven dry is 220 cm and the bulk volume of A2 oven dry is 250 cm2, determine the bulk oven dry specific gravity for each aggregate, Al and A2.

Design of a concrete mix showed that 1 m3 of the mix contains 320 kg cement, 540 kg sand. A trial mix having the same proportions as the designed mix, enough for 6 standard cubes, containing 3.5 liters water was made. It is required to calculate the quantities by weight and volume for the construction of a concrete road having 25 m width, 1000 m long, and 0.25 m thick, given that the trial mix gave slump and compressive strength as designed.Specific density of cement = 3.15Specific density of aggregate (coarse or fine) = 2.7Unit weight of cement = 1440 kg/m3Unit weight of sand = 1600 kg/m3Unit weight of gravel = 1760 kg/m3 Using BSI Method Only
