Q1. Primary aggregate may be obtained from two types of inland source, or be marine dredged. (a) For each of these three sources comment of the likely angularity of particles, and whether the surface texture is likely to be rough or smooth. [6 marks] (b) Briefly discuss how angularity of the aggregate, will affect the workability of fresh concrete and the strength of hardened concrete. [4 marks] (c) For a given mass of cement per m' of mixed concrete, briefly explain the effects that increasing the water/ cement ratio will have on the fresh and hardened concrete. Why is there a practical limit on (minimum) CO2 emissions associated with cement powder manufacture irrespective of how the energy used in manufacture is derived? [6 marks]

OAt a ready-mix concrete plant 65 tons of cement, 190 tons of fine aggregate, 250 tons of coarse aggregate and 50 tons of water are available before the end of the day. The plant manager knows that the next day (s)he has to deliver a total of 200 m³ of concrete. In the laboratory, the moisture content of sand and gravel was determined as 1.2 % and 0.2%, respectively and the absorption capacities are 0.8 % for both materials. SSD bulk specific gravities are 2.60 and 2.70 for sand and gravel, respectively. Specific gravity of cement is 3.15. Mix design based on field weight of aggregates: Ingredient Weight (kg/m2-concrete) Field Cement 350 Fine aggregate Coarse aggregate 750 950 Water 195 Calculate the maximum volume of concrete that can be produced with the available materials at the field. What should the plant manager do? [18 pts] 7) The grading of three aggregates is given below. MONSTER
