Calorimetry measures the heat generated from the early hydration reactions of cementitious materials. The heat outflow tracks the hydration reactions of cement, which gives visibility into the behaviour of concrete or mortar in a way that conventional physical testing cannot.Calmetrix, announced the launch of I-Cal 4000. This 4-channel isothermal calorimeter is used to test cement paste, mortar or even real concrete, all at a very affordable cost. It offers the ability to adjust the thermal mass of each individual reference cell. This flexibility makes I-Cal 4000 suitable for a wide range of applications, when testing different sample sizes and types. You can either employ the adjustable references supplied with the equipment or any custom made reference such as a sample of inert sand. The I-Cal 4000’s design also incorporates an improved heat sink and reduced cross talk between cells, all of which add up to better stability and accuracy.Calmetrix Inc.www.calmetrix.com
