weight of the coarse aggregate needed per unit volume of concrete mix can be estimated. FINENESS MODULUS (FM) The fineness modulus (FM) is a factor obtained by adding the percentages of material in a sample of aggregate that is retained on each of the following sieves: #100, #50, #30, #16, #8, #4, 3/8", ¾", 1 ½", 3", 6". The result is divided by 100 to arrive at the fineness ...

The size of the aggregate particles normally used in concrete varies from mm to mm. BS882 [5] places aggregates in three main egories: fine aggregate or sand containing particles the majority of which are smaller than 5 mm, coarse aggregate containing particles the majority of which are larger than 5 mm and 'allin' aggregate comprising both fine and coarse .

 · Fine aggregate: These are finegrained substances like sand that add bulk to the finished concrete. Taken together, coarse and fine aggregates make up the bulk of the concrete's mass at up to 70 percent. Air: Concrete must have air pockets in them to ease expansion and contraction. Water: This is the alyst that creates the reaction. Concrete forms from a complex reaction that starts when ...

Concrete Aggregates Additives. Because concrete is actually a mixture of items, it often contains aggregates and additives. Aggregate is a term that refers to the gravel in concrete that holds the mixture together. Concrete additives can be chemical or mineral and can help enhance the quality of the concrete mix. Chemical additives help hold down construction costs. They can also maintain ...

 · Gravel, cobble and boulders come under this egory. The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete. The size range of various coarse aggregates given below: Fine gravel: 4mm – 8mm.

 · In a mass concrete work the use of larger size aggregate will be useful due to the lesser consumption of cement. This will also reduce the heat of hydration and the corresponding thermal stresses and shrinkage cracks. But in practice the size of aggregate cannot be increased to any limit on account of the limitation in the mixing, handling and placing equipment. In large size aggregates ...

 · Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydrauliccement concrete, or iron blastfurnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Those particles that are predominantly retained on the mm (No. 4) sieve, are called coarse aggregates. Those particles passing the mm (3/8 inch)

The dividing line between fine and coarse aggregate is the 3/8inch sieve. The fineness modulus (FM) is an index of the fineness of an aggregate. The FM is calculated by adding the cumulative percentages by mass retained on each of a specified series of sieves and dividing the sum by 100 (see Table 1). The FM for fine aggregate should fall within the range of to The FM should not ...

Irregular aggregates may result 35 37% of voids. These will give lesser workability when compared to rounded aggregates. The bond strength is slightly higher than rounded aggregates but not as required for high strength concrete. Angular Aggregates The angular aggregates consist well defined edges formed at the intersection of roughly planar surfaces and these are .
