Concrete & Reinforcement Elements

The positions that govern how concrete is placed, joined and reinforced — the joints between pours, the zones around reinforcement, and the faces that form the finished surface.

5 entries in this category.

Overview

About this category

Concrete is a published material, but the things that decide how a concrete element behaves are mostly not material choices: they are positions. Where one pour stops and the next begins, how far reinforcement sits from the surface, where bars overlap, and what the concrete was cast against all shape the result, and none of them is a property of the mix.

These entries explain each position and what it depends on. They state no cover, lap length, pour sequence, bar size or strength: every one of those is a structural design value, and this library sets none of them.

Boundaries

What this category covers, and what it does not

  • Covers positions within cast concrete work: joints between pours, reinforcement laps, the cover zone, cast-in starters and kickers, the forming face, and tendon anchorage positions.
  • Does not cover the concretes, reinforcement, admixtures or waterstops themselves, which are published material entries.
  • Does not cover concrete SYSTEMS — frames, rafts, slabs, insulating formwork and water-resisting construction are building systems.
  • States no cover, lap length, bar size, pour size, strength class or striking time, and makes no structural determination.

Entries

Concrete & Reinforcement components

Every entry in this category. Each explains what the element is, what it depends on, and how it relates to materials, systems and junctions.

Continuous layerConcrete Cover Zone →The zone of concrete between the reinforcement and the surface of the member, which is what keeps the steel separated from the outside world.Continuous layerConstruction Joint →The plane where one pour of concrete stops and the next is cast against it, intended to act as though the concrete were continuous.Connector or supportKicker →The short concrete upstand cast with a slab or base that sets out and locates the formwork for the wall or column above it.Connector or supportPost-Tension Anchorage →The position at the end of a post-tensioned member where a tendon is anchored and its force is transferred into the concrete.Linear memberStarter Bar →Reinforcement deliberately left projecting from a completed pour so that the element cast next can be reinforced continuously with it.

Components are what materials become and what systems are made of. The three libraries answer different questions and are kept deliberately separate.
