advantages‚ disadvantages of types of aggregate being used in construction projects. Introduction: Aggregates are inert granular materials such as sand‚ gravel‚ or crushed stone that‚ along with water and Portland cement. Aggregates are essential ingredient in concrete. For a good concrete mix‚ aggregates need to be clean‚ hard‚ strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. Aggregates‚ which account for 60 to 75 percent

ASSIGNMENT NUMBER 1 Question Number 1: Write the definitions of aggregate demand and aggregate supply. Answer: AGGREGATE DEMAND: Aggregate demand is the sum of all demand for final goods and services at a given time and price level. AGGREGATE SUPPLY: Aggregate supply is the sum of all final goods and services that will be supplied at a given time and price level. Question Number 2: Why does short run aggregate supply curve slope upward? Answer: Because profits rise when the prices of the

Aggregate Demand AGGREGATE DEMAND (AD‚ for short) = C + I + G + (X-M) • The aggregate demand curve is not focused on a single good or service. The AD curve is focused on overall demand for all final goods & services produced across the entire economy. • Determinants of Aggregate Demand: Although the shape of the AD curve is similar to the shape of a single market demand curve‚ its shape is based on entirely different principles from what we studied in Chapter 3.

Testing of Aggregates for Concrete Pesith Chan xxxxxxxx Xavier Cure 10440269 1. Sampling of Aggregates for Testing 1. Sampling of aggregates - General Quality control tests are routinely carried out on representative samples of aggregates to ensure that any variation in quality is within the specification limits. The need for representative samples cannot be over-stressed; otherwise the test results may misrepresent the characteristics of the aggregates. Sampling operations

I. Introduction Aggregates contribute to 60-80% of a concrete mix‚ with water and cement being the other major constituents. Therefore considerable testing and consideration should be placed on aggregate type and size to ensure an adequate concrete mix. Two tests have been performed to establish the properties of the aggregates: 1. Compacted bulk density test 2. Sieve analysis II Testing For Compacted Bulk Density Objectives * To determine the specific bulk densities of a range
