Aggregate
Glossary Term
000164
The aggregate, also called concrete aggregate or concrete gravel, together with the cement paste, forms the supporting structure of the concrete.
The aggregate has an influence on the physical properties of the concrete. Depending on the material of the concrete aggregate, the elastic deformation behavior of the concrete may change. The concrete types with the limestone and sandstone aggregates have lower deformation property than the concrete types with the quartz or basalt aggregates.
The aggregate is classified on the basis of its grain composition, which is categorized by so-called grading curves. An important role for the concrete design and workability is played by the largest diameter of the aggregate used; it is also called the maximum grain.

Material Model Orthotropic Masonry 2D
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
Frequently Asked Questions (FAQ)
- When should the punching load be determined with the (un)smoothed distribution of the shear forces at the critical perimeter?
- I would like to perform the punching shear design on a column with connected downstand beams as a wall corner or Perform wall end. However, the module applies an internal column. Is it possible to adjust it?
- I am getting the message that my material does not meet the requirements of the current standard. How can I correct this?
- Is it possible to design bidirectional ribbed plates, unidirectional ribbed plates, or hollow core slabs in RFEM?
- Why are the values of a column base, head or center on the individual columns only displayed partially for the results from the calculation in RF‑CONCRETE Columns?
- What should be considered when using a failure of columns under tension in the RF‑/DYNAM Pro – Equivalent Loads add-on module?
- Is it possible to set user-defined values when viewing solid stress results?
- How are the signs for the release results of a line release and line hinges interpreted?
- How can I create a curved or arched section?
- Is it possible to manually specify a longitudinal reinforcement for design in RF‑PUNCH Pro?
