# what is the volume of aggregate mm

When the aggregate is sieved through 4.75 mm size the aggregate is retained is known as coarse aggregate. Larger than 4.75mm size is coarse sand or aggregate, so coarse aggregate size arranging between 5mm to 256 mm or more. ... Volume & size of a 50kg, 40kg, 30kg, 25kg and 20kg cement bag

### gravel calculator

A 20mm aggregate would need to be at least 40-50mm deep, and at least 50-60mm on driveways. A larger aggregate will settle and bond together better than smaller ones. The depth you will need to select for your gravel or slate will always depend on the aggregate size and what the surface will be used for. Example gravel estimate

### 1 cubic meter 20mm aggregateweight in kg - civil sir

1 cubic metre 40 mm aggregate weight in kg, As we know higher dimension of aggregate like 20mm and 40mm have lower density due to higher presence of air voids than 10 mm aggregates. Density of 20mm and 40mm aggregate ranging between 1420 kg/m3 to 1680 kg/m3, consider density of 40mm aggregate is equal to 1450 kg/m3, it means weight of 1 cubic metre of 40 mm size aggregate is equal to 1450 kgs

### hmaweight-volume terms and relationships- pavement

For typical dense-graded mixes with 12.5 mm (0.5 inch) nominal maximum aggregate sizes air voids below about 3 percent result in an unstable mixture while air voids above about 8 percent result in a water-permeable mixture

### what is coarseaggregate| requirements of good coarse

The Aggregates which has a size of more than 4.75 mm is known as Coarse aggregate. The Aggregate sizes which range from 4.75 mm to 80 mm are the coarse Aggregates and the 150 microns to 4.75 mm aggregates are known as Fine Aggregates. The size 4.75 mm is common for both fine Aggregates as well as coarse Aggregates

### volume calculator

volume=1/3 × π × 4(0.2 2 + 0.2 × 1.5 + 1.5 2) = 10.849 in 3 Ellipsoid An ellipsoid is the three-dimensional counterpart of an ellipse, and is a surface that can be described as the deformation of a sphere through scaling of directional elements

### coarseaggregatespecific gravity - pavement interactive

It is formally defined as the ratio of the mass of a unit volume of the impermeable portion of aggregate (does not include the permeable pores in aggregate) to the mass of an equal volume of gas-free distilled water at the stated temperature

### calculate quantities of materials for concrete-cement

Coarse aggregates = 2.6. The percentage of entrained air assumed is 2%. The mix proportion of 1:1.5:3 by dry volume of materials can be expressed in terms of masses as: Cement = 1 x 1500 = 1500. Sand = 1.5 x 1700 = 2550. Coarse aggregate = 3 x 1650 = 4950. Therefore, the ratio of masses of these materials w.r.t. cement will as follows =

### aggregates volume

Aggregate Volume = 7 * 5 * 12 Aggregate Volume = 420 m 3 Amount = 1.3 * 420 Amount = 546 tonnes

### density of aggregate- bulk and relativedensity- civil

Unit in kg/m 3 or lb/ft 3. In this definition, the volume is that contains both the aggregates and the voids between aggregates particles. The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m3 (75-110 lb/ft3)

### calculate cement sand & aggregate - m20, m15, m10, m5

Cement, Sand and Coarse aggregate requirement for M20 Grade concrete. Prescribed Concrete Mix Ratio of M20 grade concrete is 1:1.5:3 as per codebook. Cement = 1 Part; Sand = 1.5 Part; Aggregate = 3 Part; Total dry volume of Material Required = 1.57 cu.m

### aggregates- typesof aggregates| coarseaggregate, fine

Aggregates Definition: Aggregates are coarse particulate rock-like material consisting of a collection of particles ranging in size from < 0.1 mm to > 50 mm. It includes gravel, crushed rock, sand, recycled concrete, slag, and synthetic aggregate

### how to calculate quantities of cement, sand andaggregate

We have given the materials requirement for M15, M20, M25 and M30 Grade Concretes in the blog. Please refer. If you want 10 mm and 20 mm aggregate mixed in the concrete, mix it in the ratio of 50:50 (of coarse aggregate volume). PCC should be usually be …

### what isbulk density and % of voids of fine aggregates

Bulk density is defined as ratio of mass of fine aggregates by the total volume they occupy. Total volume means volume of fine aggregate, volume of inter particles between them and volume of internal pores present in fine particles. ... Tamping rod:- tamping rod is 16mm rounded bar of length 600 mm which have tamping nose at one end and second

### coarseaggregates: types, properites & applications

Coarse aggregates are obtained from stone quarries and stone crushers, the size between 4.75 mm to 80 mm. Good qualities of an ideal aggregate: A correct aggregate used for the construction of concrete and mortar must meet the following requirements. This should include natural stones, gravel and sand or various mixtures of those materials
