Concrete in 1970s: Superplasticisers

Read the condition on Concrete before the nickname. Year 1970s, line “Superplasticisers,” figure 1. Lime-pozzolana harbour concrete still studied at Caesarea and Rome.

This atlas treats Concrete as a system: mill route, coatings, tests and the cavity it sits in. Conductivity note: ~1.4 W/m·K. Insulation score 22/100 is relative to 32 entries — metals lose, VIPs and aerogels win. Fire letter in editorial use: A1. Do not equate A1 with “safe in a blaze” or E with “illegal”. Assemblies decide.

Origin: Roman pozzolana; Aspdin 1824; Hennebique RC, Rome → Leeds → Paris. The process chapter follows feedstock → conversion → forming → finish → install. Uses span buildings to defence / safety. Pairings matter: steel. Circularity mark 30/100. Ask which scrap, which certificate, which year.

Related atlas entries, a short glossary, and three threads that keep Concrete honest. Interior fire linings on concrete frames. The other mass-timber rival for mid-rise. EN 13501-1 reaction-to-fire letter (A1–F), not a wall rating. Thermal conductivity in W/m·K. Lower means better bulk insulation.

The label keeps Concrete, 1970s, and 1. “Superplasticisers” is the condition on the figure.1970s
