An Introduction to Concrete Density and Aggregates Objective: The objective of this experiment is to determine the density of a concrete sample and to learn the effect of various types of aggregates on concrete's density. Scientific Principles: Density is the physical property of matter that measures the quantity of a substance per unit of space.

Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.

In concrete, aggregate is the granular substance that holds the mixture together in its solid form. Aggregates vary in size and shape, and they can be as finely ground as sand or as coarse as gravel. When mixed with water and cement, these compounds form concrete. Aggregates make up between 6075% of the volume of the final mixed concrete.

Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or largesize gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soilcement.

Aggregates Aggregates generally occupy 65 80% of a concrete's volume. Aggregates are inert fillers floating in the cement paste matrix for concretes of low strength. The strength of aggregates do not contribute to the strength of concrete for low strength concrete. The characteristics of aggregates impact performance of fresh and hardened

Following is a simple method used by engineers to calculate cement, sand and aggregate to produce different grade of concrete like M5,, M10, M15 and M20. if you don't want to learn the math involved in the design, you can use the table given at the end of the article to produce different grade of concrete.

Abstract: The aim of this study is to investigate the characteristics exhibited by three different grades of concrete using mix design approach. From the result of the sieve analysis, it shows that the sands used for the experiment is a well graded sand of zone 1 of BS882 parts 2 (1973).

aggregates, with typical range values, are shown in Table 2. Coarse and fine aggregates are generally sieved separately. That portion of an aggregate passing the mm (No. 4) sieve and predominantly retained on the 75 µm (No. 200) sieve is called fine aggregate or sand, and larger aggregate is called coarse aggregate.

6. If more than one type of coarse aggregate is being used, first find the optimal composition of the blend and then determine the characteristic diameter and packing density of the combined aggregate as described in steps 1 and 2. Then find the optimal composition of the combined aggregate with the sand.
