Abstract

he production of self-compacting concrete is connected with the development of plasticizers based on polycarboxylate ethers. The first patent for a group of substances proposed for use as superplasticizers for concrete was announced in the early 80s of the last century in Japan. With the use of superplasticizers based on polycarboxylate ethers widely known objects were constructed: a bridge crossing the bay in Tokyo (Tokio Bay Bridge) and high-rise buildings in Tokyo downtown (Tokio Central Towers).
In the mid 90,s the superplasticizers based on polycarboxylate ethers were introduced in Europe. In Russia the usage of self-compacting concrete started much later and in bridge and tunnel construction it started practically a few years ago.
At present in the European Union 60–70 % of all erected reinforced concrete structures are made of self-compacting concrete mixes and the concretes themselves are called self-compacting everywhere. In Russia these are sometimes called self-leveling concretes. The volume of their usage is quite small.

Key words:

self-compacting concrete; self-compacting concrete classification; test methods; the construction of supporting structures; concreting stages
