What is the density of aggregate base?
What is the density of aggregate base?
Most aggregates have a relative density between 2.4-2.9 with a corresponding particle (mass) density of 2400-2900 kg/m3 (150-181 lb/ft3).
What is class II aggregate base?
Class II Base is a crushed and graded blend of aggregates designed to compact tightly with the proper equipment. It provides an excellent base to concrete pavers and asphalt or can be used alone as a driveway or pathway.
What are the classification of aggregate based on density?
According to [41], aggregates in concrete can be classified into five main groups namely: ultra-lightweight (ULW), lightweight (LW), structural lightweight (SL), normal-weight (NW) and heavy-weight (HW) concretes based on density as shown in Table 4.
How do you calculate aggregate density?
Procedure for Compacted Bulk Density. Measure the volume of the cylindrical metal measure by pouring water into the metal measure and record the volume “V” in litre. Fill the cylindrical metal measure about one-third full with thoroughly mixed aggregate and tamp it 25 times using tamping bar.
What is Type 2 aggregate?
Our Type 2 is a crushed aggregate with extra dusts and fines, which makes the perfect sub base for a range of domestic and commercial construction projects. Graded to 50mm down to dust and fines no specified grading, it is finer than our MOT Type 1 sub base, as it is composed of fewer larger angular scalpings.
What is the density of 20mm aggregate?
20 mm aggregate density:- density of 20 mm aggregate is 1550 kg/m3, it means 1 cubic metre of 20 mm aggregate weight is 1550 kg.
What is Type 2 aggregate used for?
It usually contains finer material than type 1, being composed of fewer angular aggregate sizes also know as scalpings. Type 2 mot can be used for driveways, backfill material, paths and patio areas and to fill in pot holes and compacts down to a hard base.
What are the two types of aggregate?
Aggregates Definition: Types of aggregates include Coarse aggregate and fine aggregate. The aggregate of each type is further sub-divided into many types and classification based on its size. The technique of Sieve Analysis is used for gradation of aggregate for use in concrete and for other applications.
What is the density of type 1 aggregate?
2200Kg/m³
Sub-base Material
| Size | Type | Density m³ Compacted |
|---|---|---|
| 0/31.5mm | Type 1 Granular Sub-Base SHW803 | 2200Kg/m³ |
| 0/31.5mm | Type 3 Granular Sub-Base SHW805 | 2200Kg/m³ |
What are the different sizes of aggregate?
Coarse Aggregate
| Coarse aggregate | Size |
|---|---|
| Medium gravel | Ad 8mm – 16mm |
| Coarse gravel | 16mm – 64mm |
| Cobbles | Ad 64mm – 256mm |
| Boulders | >256mm |
What is the density of 12.5 mm aggregate?
1.6840 gm / cm³ (2) Bulk density of three aggregates i.e., CA 20mm : CA 12.5mm : FA is 42 : 18 : 40. (coarse aggregate 20 mm : 12.5 mm i.e., 70 : 30 as fixed earlier). PD = 0.7223 gm / cm³ This packing density value is fixed for further calculations.
How big is a Class 2 aggregate base?
20 mm or 3/4 inch Aggregate Base, Class 2, is used in roadways and is an aggregate made of a specific recipe of different sizes and quality of rock inclusive of 20 mm (3⁄4 in) to fine dust. An aggregate is normally made from newly quarried rock, or it is sometimes allowed to be made from recycled asphalt concrete.
How to calculate the base density of an aggregate?
A common practice of industry professionals is to divide TONS by (2) to get CY. Dividing TONS by (2) to get CY assumes that the in place aggregate will have a density of 148 lb/ft^3.
How to calculate the density of natural gas?
Natural Gas Density Calculator Pressure Density 1 7.166 2 14.647 3 22.459
What makes up a Class II base material?
Class II Base Material Start With A Strong Foundation Aggregate consists of hard, graduated fragments of inert mineral materials, including sand, gravel, crushed stone, slag, rock dust, or powder. Made from a mixture of different sizes of crushed rock from 3/4″ all the way down to fine dust.
