Testing of Self-Compacting Concrete (SCC)

We also provide self-compacting concrete testing based on BS EN 206-9 specification:

  • Slump-flow test
  • V-funnel test
  • L box test
  • Sieve segregation test
  • J ring test
  • Adiabatic Temperature Rise

Why is temperature control necessary?

All concretes generate heat as the cementitious materials hydrate. Most of this heat generation occurs in the first days after placement. For thin items such as pavements, heat dissipates almost as quickly as it is generated. For thicker concrete sections (mass concrete), heat dissipates more slowly than it is generated. The net result is that mass concrete can get hot.Management of these temperatures is necessary to prevent damage, minimize delays, and meet project specifications.

Determination of concrete adiabatic temperature rise

The test determines the quantity of heat released from the concrete during its hardening process in an adiabatic condition at regular intervals from the just after casting of the specimen. The test is carried out using an adiabatic calorimeter which has been constructed to minimize the heat loss from the concrete sample.A sample of freshly mixed concrete is placed in a container which is then introduced into the adiabatic calorimeter and the internal temperature of the hardening concrete is measured.

Check your concrete temperature now with us

In large concrete elements, the interior is considered to be hydrating in an essentially adiabatic process. Because of the low thermal conductivity of concrete, the heat of hydration from its interior is prevented from being released into the environment, thus a negligible amount of heat is lost. Admaterials had developed adiabatic calorimeter that can be used to determine maximum concrete temperatures and temperature differences for any concrete mix design.
