Q.3 (a) A new concrete bridge is to be constructed near the sea and its design has to incorporate features protecting it from exposure to marine environments. Among these, a new coating system is being proposed for concrete. You have been awarded a six-month contract to evaluate this system and materials involved. Describe the major parts of your programme, assuming that you also have access to a structure on which the coating has recently been used. (b) Aggregate is one of the main materials used in the production of concrete and its physical properties as well as the size distribution can affect the properties of fresh and hardened concrete. Discuss the influence of absorption and surface moisture conditions of mineral aggregate on fresh and hardened concrete properties.

A structure is to be built with concrete with a minimum dimension of 0.2 m, minimum space between rebars of 40 mm, and minimum cover over rebars of 40 mm.Two types of aggregate are locally available, with maximum sizes of 19 and 25 mm,respectively. If both types of aggregate have essentially the same cost, which one is more suitable for this structure?

You see the concrete looks dry as it is being placed as a slab. a) If you decide to spray some water on the surface before the concrete has set, what could happen to the concrete in terms of strength and any potential abnormalities/distresses? b) You decide to instead wait for the concrete to set, and then you decide spray water on the surface. What could happen to the concrete in terms of strength, shrinkage, density, and any potential distresses?
