2.Shape of Coarse Aggregates: Water absorption will reduce the amount of water content in the concrete, it will require a greater water/ cement ratio. Coarse aggregates give strength to concrete. The sand, which is fine aggregate, fills the void in coarse aggregates and is a cement binder.How Coarse Aggregate Affects Mix Design of Concrete?,2. Grading of Coarse Aggregate. Grading is the determination of the particle-size distribution for aggregate. It affects the amount of cement and water requirements, workability, pumpability, and durability of concrete. The grading of coarse aggregate is important to get cohesive and dense concrete.

How to calculate the 1:1:2 ratio of concrete cement
1:1:2 (1 part of cement : 1 part Sand: 2 part of CA) is for M25 Grade. Cement required for this ratio is [1/(1+1+2)]*1.54*1440 = 554 kg/m3 (usually Cement measured in Bags so 554*50= 11 Bags) (where 1.54 is Dry to wet volume constant,& 1440 is d.Calculate Sand & Gravel per 50kg Cement Bag in Volume,The ratio of fine aggregate to coarse aggregate to be used in concrete is 1:2, which means that for every 1 part of sand we have to take 2 part of gravel. Hence we have to divide the Total Aggregate into 3 parts and take 1 part as sand and 2 parts as coarse aggregate. Lets calculate weight of sand and gravel needed for M15 Grade concrete.
Different Types & Sizes of Aggregate for Concrete
Aug 11, 2018· Coarse aggregates are particulates that are greater than 9.5mm. The usual range employed is between 9.5mm and 37.5mm in diameter. Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water needed Effects of Aggregate Properties on Concrete Size, Grading,Variation in the size of Aggregates changes the water demand, cement content, micro-cracking (strength) in concrete. It also effects pumpability, and durability of concrete. Grading of aggregates depends on the proportions of coarse and fine aggregate. If grading of aggregate is varied, it also changes cement paste content (cost economy), workability of the mix,
