Due to problems with the pink stone quarry Sepúlveda, we have moved our field of study Novelda stone, which has a greater ease of collection, and a cheaper cost.
addition, the difficulty of carrying out the test as specified in the standard and advanced the progress made to tailor the characteristics and performance of test cycles to our possibilities.
The material we have is: -18
5x5x2 cm specimens, cut into workshop, of which:
a-6-finish polished (as received Factory)
b-6 Bushhammered shop
c-6 chiseled shop
-Barreno with water to soak the stone in the process of absorption and thawing.
-Frost House
-Oven
adapted cycles with which we perform the test are:
1. Water absorption period of 18 samples, for about 5 hours
2. Beginning of freeze / thaw, following these steps:
2.1. Introduction in the House of Frost, to achieve the freeze the water absorbed by the pores. At an estimated time of 20 hours.
2.2. Removed from the camera and start to soak for 4 hours to thaw and water absorption.
3. Repeat the cycle up to 9 times, carrying out health checks of the stone every 3 cycles,
4. Final drying at 70 degrees to make the final verification of the damage to the stone.
5. Development of a comparative report for each of the finishes.
checks the state of the specimens will be primarily visual.
Today 24th April 2006, we started the test samples with the chiseled and bush hammered finishes, leaving in each sample a margin of 0.5 cm in the side to avoid tearing the edges of the stone. Then we stopped to soak the specimens, thus starting the cycles.
After 5 hours, we have introduced the specimens in the chamber of Frost.
