Concrete’s versatility, durability, sustainability, and economy have made it the world’s most widely used construction material. Lesson Notes: Special attention should be given to the nine properties of good, durable concrete (they will be discussed in detail in subsequent chapters) and their relationship to the five fundamentals of concrete construction. Mix a 'Topping Coat' – a mix of aggregates and cement paste in the ratio An intermediate-sized aggregate, around mm (3/8 in.), is sometimes added to improve the overall aggregate gradation. METHODPlace, compact and level the concrete to aboutmm below the top of the forms. Clean any concrete from around the base and top of the cone, push down on the handles and step off the footpiecesCarefully lift the cone straight up making sure not to move the sampleTurn the cone upside down and place the rod across the up-turned cone The maximum size of coarse aggregate is typicallymm ormm (3/4 in.
