1. Size of Aggregate. Crushed concrete shall be processed to reach suitable sizes. The crushing method (mechanical or manual) of concrete to produce coarse aggregate for the production of new concrete is one of the factors that affect the strength of the concrete. It is reported that, coarse aggregate which comply with standards can be produced.
Influence of Recycled Aggregate on Concrete Properties 1. Concrete Strength Reductions . By and large, strength of concrete produced from crushed concrete aggregate is lower than concrete made using natural aggregate. Strength reduction of concrete produced from recycled coarse aggregate and natural fine aggregate ranges from 5 to 24%.

• Recycled aggregate is derived from crushing inert construction and demolition waste. It may be classified as . recycled concrete aggregate (RCA) when consisting primarily of crushed concrete or more general . recycled aggregate (RA) when it contains substantial quantities of .
However, the production function has reduced to capital and labor, so that it can be easily understood. A two variable production function can be expressed as follows: Q = f (L, K) Other factors are excluded from the production function due to various reasons. Land and building are excluded because they are constant for aggregate production function.

This description is applied to concrete which contain only a single size 10mm to 20mm coarse aggregate (either a dense aggregate or a light weight aggregate such as sintered PFA). The density is about twothird or three quarters that of dense concrete made with the same aggregates.
Aggregate demand is the total demand made by all members of the society for all goods and services. In macroeconomic analysis such aggregate demand is a function of the general level of prices. Here, the price of any individual good or the demand for it from an individual member is not under consideration.

CHAPTER 14. AGGREGATE PRODUCTION
The aggregate per capita production function is very similar to the aggregate production function, except that all elements are divided by the population. The inputs are the average level of human capital per person, the average level of physical capital per person, and the level of technology per person.
Aggregate particles have certain physical and chemical properties which make the aggregate acceptable or unacceptable for specific uses and conditions. The following are of concern to INDOT. PHYSICAL PROPERTIES The physical properties of aggregates are those that refer to the physical structure of the particles that make up the aggregate.

Aggregate Planning Strategies. 1. Use inventories to absorb changes in demand 2. Accommodate changes by varying workforce size 3. Use parttimers, overtime, or idle time to absorb changes 4. Use subcontractors and maintain a stable workforce 5.
Moreover, using recycled concrete aggregates reduces the need for aggregates. This in turn reduces the environmental impact of the aggregate extraction process. By removing both the waste disposal and new material production needs, transportation requirements for the .
