Isothermal Calorimeter

The hydration heat of polymer modified mortar were measured at 5°C、10°C、20°C and 40°C using Multi-channel Isothermal calorimeter. The effects of temperature on hydration heat of polymer modified mortars with 0.1% methyl hydroxylpropyl cellulose (MHPC), 3% ethylene vinyl acetate (EVA) and 0.1%MHPC+3%EVA were investigated. The curves of hydration heat show that the polymer reduces the hydration heat of mortars and it is related to the temperature. The effects will be more and more remarkable with the increasing of temperature; Temperature also affects the exothermic rate peak of polymer modified mortars. The exothermic rate peak of polymer modified mortar at low temperature is almost equal to that of the ordinary cement mortar. However, it is obviously lower than that of ordinary cement mortar at high temperature ; The time to the exothermic rate peak of polymer modified mortar is also related to the temperature.
