Ensure that the mixing procedure is sufficient to disperse binder properly If the water cement w c ratio is pre defined perform a pre test mix with blank cement paste or mortar no admixtures and another pre test with the highest desired dosage of admixtures Adjust w c ratio if necessary If the water demand of the cement admixture combination to be tested is unknown perform a pre test to determine required water to binder ratio binder includes cement and any supplementary material used as a cement replacement Preparation 4 14 We recommend you start logging data in your P Cal at least one hour before inserting the first sample This allows the unit to reach a stable baseline temperature Pre dilute admixtures to ensure accurate weighing or use high accuracy micro pipettes for accurate volumetric dosing Use the same mixing sequences and times as far as possible within a test series Prepare concrete according to standard or sample concrete directly from production in batch plant mixer or ready mix truck Be sure to enter mix data in the Mix Configuration area of the P Cal Logger tab for future reference Calmetrix 1000 User Manual 2014 Calmetrix Inc All rights reserved 8 Fill your 100mm x 200mm or other standard sample container completely Make sure the container is properly closed to avoid any spillage Insert the container into the P Cal and close it by securing the three latches G VISUALIZI

Manual 2014 Calmetrix Inc All rights reserved H INFERRING SETTING TIMES F P CAL SET F P Cal Set has two ways to infer setting tines Method 1 Post testing analysis of calorimetric curves to infer setting times in lieu of physical testing such as with a penetrometer needle This feature is useful if you have multiple samples in a large test matrix and need approximations of setting times without incurring the cist and time for physical testing Method 2 Live analysis while conducting a calorimetry test to infer setting times or saw cut times and get notified when mix reaches its initial of final setting time or saw cut time This method can be applied to get an indicator of when to start performing finishing work How to use Method 1 Post testing analysis F P Cal Set can help you infer initial and final setting times within close approximation by applying the Fractions Method and generate Thermal Indicators of Set TIS This method is based on the assumption that for a given mix design there is a correlation between the heat evolution and setting times Initial set is reached when the temperature level in a sample placed in the P Cal reaches a certain fraction of the peak Each mix has its very own fraction values corresponding to initial and final set Once the fraction values are determined for a given mix design they can be used to predict setting times when the same mix is used again in the future To be able to
