Coarse Aggregates: Types, Properites & Applications

2 天前  2.Shape of Coarse Aggregates: The shape of the aggregate is a crucial characteristic because it impacts the workability & strength of the concrete. In general, the angular aggregate is desirable for round and smooth sets for the following reasons: The angular aggregate shows better interlocking effect which gives a better concrete.

Effect of type of coarse aggregate on the strength

2018-5-1  An attempt has been made in the present work to study the effect of type of coarse aggregate on the strength properties and fracture energy of M30, M50 and M80 grade of concretes. The aggregate used in this study includes Grey Granite (GG), Anorthosite (AS)

Different Types & Sizes of Aggregate for Concrete

2018-8-11  Larger aggregate diameters reduce the quantity of cement and water needed because of its lower Voids. When the aggregate is sieved through 4.75mm sieve, the aggregate retained is called coarse aggregate. Gravel, cobble and boulders come under this category. The maximum size aggregate used may be dependent upon some conditions.
