Optimisation of the aggregates composition in concrete

2016
Hardened concrete has a complex structure in which two parts can be distinguished - the matrix (hardened cement-sand grout) and the insertion of coarse aggregate particles. The aggregates make up to 80 % by volume of concrete. The cost of aggregates also reaches 30 % - 50 % of that of concrete. Therefore it is natural that aggregates largely affect the

Choosing Aggregation Rules for Composite Indicators

Social Indicators Research, 2011
From a formal point of view, a composite indicator is an aggregate of all dimensions, objectives, individual indicators and variables used for its construction. This implies that what defines a composite indicator is the set of properties underlying its mathematical aggregation convention.

Generic composition of fungi in soil aggregates

Folia Microbiologica, 1996
A structure of fungal flora was studied in aggregates of various diameter in a chernozemic rendzina and a lessive soil. Aggregate diameter influenced strongly the distribution of fungi such asCephalosporium, Fusarium, Penicillium and sterile mycelia. The percentage of the above fungi changed with changing aggregate diameter as follows:Cephalosporium: 1–

Objects Working Together: Association, Aggregation, and Composition

2012
Many objects can be seen as being made up of smaller objects. For example, a clock is made up of a number of components that together combine to make the whole object. The combination of objects may exist in many layers, with a larger component (such as the mechanism) being itself made up of a collection of smaller components.
