Secant piles are often used in beachfront scour protection walls and basement groundwater cut-off walls. Secant piles are being used in a new construction to create a retaining wall to inhibit the passage of water. Consider blended cements and their impact on strength development and durability. a) which of the following supplementary cementious materials is ideally recommended in this situation. Give reasons why/why not. 1. silica fume 2. limetsone fines 3. ground granulated blast furnace slag 4. nanosilica b) Justify the answer, explain the mechanism in which the use of supplementary cementitious materials work and how it facilities the process of piling. Use graphs and diagrams to illustate the answer.
