It was named because of the similarity of its colour to Portland limestone , quarried from the English Isle of Portland and used extensively in London architecture. Aggregate with a very even size distribution has the biggest gaps whereas adding aggregate with smaller particles tends to fill these gaps. Vacuum concrete stiffens very rapidly so that the formworks can be removed within 30 minutes of casting even on columns of 20 ft. It is heavy and hard to work. A drawback is that the mixing has to be done in an airtight container. Self-consolidating concrete, also known as self-compacting concrete SCC , is a highly flowable, non-segregating concrete that spreads into place, fills formwork, and encapsulates even the most congested reinforcement, all without any mechanical vibration. Cement , most commonly Portland cement , is associated with the general term "concrete. Reinforced concrete Constructing a rebar cage that will be permanently embedded in a finished reinforced concrete structure Concrete is strong in compression , as the aggregate efficiently carries the compression load. For this reason it is usually reinforced with materials that are strong in tension, typically steel rebar. In addition to being decorative, exposed aggregate may add robustness to a concrete. Shotcrete is frequently used against vertical soil or rock surfaces, as it eliminates the need for formwork. Over the last decade, there has been a renewed interest in using lime for these applications again.
