*2.3. Evaluation of the Flowability of Cement Paste Mixes*

The flowability of cement paste mixes was measured through the flow table test, according to the PN-EN 1015–3:2000. The truncated cone-shaped mold was placed on the spreader disc, and the cement paste mix was applied in two layers, thickening each for at least 10 strokes of the compactor. Then, the excess paste was scraped off, and after 15 s, the mold was slowly removed by lifting it vertically. After shaking the disc 15 times, two diameters of the mix oriented perpendicularly to each other were measured, and their average value was assumed to be the final one.
