Aggregate is an aggregation of non-metallic minerals obtained in particulate form and can be processed and used for civil and highway engineering construction. Aggregates are mainly classified into tw
Fine aggregate is the essential ingredient in concrete that consists of natural sand or crushed stone. The quality and fine aggregate density strongly influence the hardened properties of the concrete.. The concrete or mortar mixture can be made more durable, stronger and cheaper if you made the selection of fine aggregate on basis of grading zone, particle shape and surface texture, abrasion

This study proposes improved sustainable mix design using packing density method by optimization of parameters such as water-cement ratio, coarse to fine aggregate ratio, quarry dust to natural sand ratio, cement content and compaction effort. Trial mixes were tested increasing excessive cement content from 20% to 40% in 5% intervals.
Natural heavyweight aggregate. MagnaDense is a natural aggregate manufactured from the iron oxide Magnetite. With its high specific gravity MagnaDense is used as a coarse material to produce heavyweight concrete. As a result, you will get high density concrete that has more weight and your project will require less volume.
If the particles are of the same size, then it can be packed to a limited extent but when the smaller particles are added, the voids get filled with them and thus the bulk density increases. For a coarse aggregate, a higher bulk density means that there are few voids which are to be filled by the fine aggregate and cement.
CHAPTER 3 PHYSICAL PROPERTIES OF STRUCTURAL LIGHTWEIGHT AGGREGATE 3.0 Introduction sometimes and is referred to as low density aggregate. for fine aggregate and less than 55 lb/ft³ (880 kg/m³) for coarse aggregate. This includes aggregates prepared by expanding, pelletizing, or sintering products such as blast-furnace slag, clay
COARSE AGGREGATES Section 904.03 defines the acceptable limits for all uses of coarse aggregates. Coarse aggregates are divided into classes based on quality requirements as noted in the Classification of Aggregates table. Class AP is the highest class and is assigned to aggregates which m eet the requirements for all INDOT uses.

AASHTO T 85 and ASTM C 127: Specific Gravity and Absorption of Coarse Aggregate; Background. Specific gravity is a measure of a material’s density (mass per unit volume) as compared to the density of water at 73.4°F (23°C).
Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Types of aggregates include Coarse aggregate and fine aggregate.
Aggregates can be classified in many ways. Classification of aggregates based on shape and size such as coarse and fine aggregates are discussed here, Aggregates are the important constituents of the concrete which give body to the concrete and also reduce shrinkage. Aggregates occupy 70
density of soils utilizing a 5.5 lb. hammer dropped at a height of 12 inches to compact layers of soil in a standard mold. The test is used to define the optimum level of soil or aggregate that can be compacted into a unit volume with a level of compactive energy that is similar to that obtained by standard construction equipment.
The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate. The strength of coarse aggregates is assessed by aggregates crushing test. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load.
Jun 09, 2005 The (150-180) density data comes from a "Design and Control of Concrete Mixtures" book and appears to refer to the "particle" density of aggregate. However, since the aggregate is made up of particles, it is reasonable that the compacted density of the aggregate is between (150-180 lb/ft^3).
