Creating Dimensions and Cubes

Aggregation: Generates aggregate values using the rules defined for the cube. You can aggregate the entire cube, selected measures, or selected portions of the cube. Analyze: Generates optimizer statistics, which can improve the performance of some types of queries. For more information, see "Analyzing Cubes and Dimensions". Generating statistics is typically done immediately after data maintenance.

Also, the shape of aggregates used in concrete is an important parameter that helps determine many concrete properties, especially the rheology of fresh concrete and early-age mechanical properties (Erdogan, 2005;Erdogan et al., 2006).Aggregates shape, texture and grading have a significant effect on the performance of fresh concrete.

Aggregates for Concrete

Coarse aggregate may be available in several different size groups, such as 19 to 4.75 mm (3/4 in. to No. 4), or 37.5 to 19 mm (1-1/2 to 3/4 in.). ASTM C 33 (“Standard Specifications for Concrete Aggre- gates”) lists several such size groups using the simplified practice recommendation (SPR) number designation.

How to Choose Quality Coarse Aggregate for Concrete Construction?

Angular and fairly cubical coarse aggregate particles are desirable. Coarse aggregate should contain various fraction sizes to ensure adequate compaction of particles, hence resulting in increased density and reduced voids in concrete. In the majority of concrete works, aggregate sizes of 20 mm or smaller are used.

HOW AGGREGATE PROPERTIES AFFECTS CONCRETE

Shape of Aggregate. Shape of aggregate can be broadly classified as follows in order of desirability like Rounded, Irregular rounded, Cubical, Flaky angular, Elongated, Flaky elongated. Rounded. Rounded shape has minimum surface area for the same mass than other shapes therefore it requires minimum cement paste for bonding as compared to other shapes.
