To ensure the quality of the concrete used for every construction project as a part of quality control and compliance of relevant regulation and quality standard, Admaterials is able to provide you acomprehensive range of concrete tests. Our capability is not only providing fresh and hardened concrete tests, but also mix design assessment and admixture testing.
Testing of Fresh Concrete
Admaterials is capable of performing the following tests to assess the fresh concrete properties:
Testing of Admixture
We are also able to provide full range of admixture tests as required in SS EN 934 for general and specific requirement:
Testing of Self-Compacting Concrete (SCC)
We also provide self-compacting concrete testing based on BS EN 206-9 specification:
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.
Are you worried about these problems?
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.

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.
