Aggregate (CR +1) "Aggregate" is an acquired template that can be added to any robot (referred to hereafter as the base robot), that gains some of the characteristics of an artificial intelligence (AI) installed in it (referred to hereafter as the base AI).The base robot must have the storage capacity to house the base AI (subject to the GM's discretion).

Understanding Coarse Aggregate. Coarse aggregate is a term used to describe the larger-sized particles that form the bulk of concrete mixes. These particles are typically greater than 4.75 mm (0.187 inches) in diameter.
Type 1 is a granular sub-base material, consisting of aggregate that is crushed and screened to provide a blend of aggregate size from 40mm down to fine dust. This range of particle sizes ensures the material is easy to compact to create a solid …
Aggregation is a type of association relationship that connects two things.Aggregates are one of the most essential constituents of concrete as it is a binding material in concrete that makes it durable and strong. Aggregates occupy around 70% to 80% of the concrete's entire volume, making it a significant factor that affects the concrete's properties and characteristics.

Recycled Aggregate . Recycled aggregate represents a sustainable solution in the construction industry. It encompasses crushed recycled concrete and reclaimed asphalt pavement (RAP) that undergo processing to meet desired specifications.
(1) For products containing less than 25 percent recycled materials, conform to Table 3138-3. (2) For products containing 25 percent or more recycled materials and less than 75% recycled concrete, conform to Table 3138-4. Bituminous millings meeting a gradation of passing the 1.5" sieve and 95- passing the 1"
There are different Types of Aggregates used in concrete such as Rounded aggregate, Flaky, and aggregates, angular aggregates, Irregular shaped aggregate.
1. Course aggregates: aggregate particles that are retained on a 4.75 mm sieve (metric No.4). particle size ≥ 5 mm 2. Fine aggregates: aggregate particles that pass a 4.75 mm sieve (No. 4). particle size < 5 mm. Fine aggregates content usually 35% to 45% by mass or volume of total aggregate (b) 4.1.2 Unit weight classification
