Cement & Concrete

The hydration process of cement and concrete is exothermic, i.e. heat is developed. For large structures this will result in temperature gradients within the product which may lead to temperature induced stress and cracks.

 

Services

  • Qualityc control of different batches
  • Determination of the rate of heat production
  • Simulation of temperature gradients
  • Simulation of temperature induced stress and risk for cracking

 

Analytical techniques

  • Heat Flow Calorimetry (HFC) - rate of heat production
  • Semiadiabatic calorimetry (SAC) - temperature increase
  • Compression testing
  • Tensile testing
