In Figure 7, the determined minimum water contents for the use of different types of admixtures are presented. It should be noted that reducing the water content also directly reduces the paste content. Therefore, when designing fresh concrete, this reduction must be considered and adjusted accordingly if necessary.In an exemplary experimental study, the water content of concretes with different fine aggregates (S1, S3, and S4) was systematically varied. The initial concrete mix was produced with a cement content of 360 kg/m%u00b3, a w/c ratio of 0.49, and a resulting paste content of 295 l/m%u00b3. In subsequent steps, the water content was gradually reduced from 176 l/m%u00b3 to 162 l/m%u00b3 and 146 l/m%u00b3, while keeping the cement content constant at 360 kg/m%u00b3. This reduction to 162 l/m%u00b3 led to a lower paste content of 280 l/m%u00b3. When the water content was further reduced to 146 l/m%u00b3, the paste content was adjusted back to 280 l/m%u00b3 by adding limestone powder (see Fig. 8). All concrete mixes were adjusted to a slump flow diameter of 52 %u00b1 3 cm (consistency class F4) by adding a standard PCE-based superplasticizer.Fig. 8: Paste content of the investigated concrete mixes with varying water content (176 - 147 l/m%u00b3) at a constant cement content of 360 kg/m%u00b3.1 RECEPTION HOPPER4 HOPPERS OF 70 MC / EACH FOR A TOTAL OF 280 MC8 HOPPERS OF 35 MC / EACH FOR A TOTAL OF 280 MC1 LOADING SYSTEM WITH BUCKET ELEVATOR FOR HOPPERS3 CEMENT SILOS OF 80 TON EACH2 PLANETARY MIXERS MPR SERY HIGH PERFORMANCE 3000/2000 LTMIXER AUTOMATIC WASHING SYSTEM1 AGGREGATE MOBILE WEIGHING BUCKET2 CEMENT SCALES2 WATER SCALES2 ADMIXTURE SCALESCONTROL PANEL IN PROTECTION CABINCAMERAS VIDEO CONTROL1 DIRTY WATER DOSER1 DIRTY WATER TREATMENT SYSTEMAUTOCLAVE WATER SYSTEM WITH STORAGE TANKEXCELLENCEIN CONCRETE BATCHING PLANTSTAILOR MADE BATCHING PLANTSTURNKEY SOLUTIONSTOWER CONCRETE BATCHING PLANT TK TYPE FOR A HIGH PRODUCTION OF QUALITY CONCRETE FOR THE PRODUCTION OF PRECAST ELEMENTSCMYCMMYCY CMYKRocchi logo allargato.pdf 1 11/03/19 17:24
