TEIDE REFRACTORY SOLUTIONS, S.L. DELEGATES AGING OF CONCRETE

Concretes get damaged year after year; this damage can be increased if they are submitted to AUSES as:

• Long time storage.
• High environmental humidity
• Fluctuations of temperature and humidity

Main PROBLEM of the concrete: Inside the bag, the concrete sets partially. Hardens, forms lumps and its use becomes impossible.

CONSEQUENCIES:

• Important economic losses
• Delays in the process of the works untll receive new material

Ordering small amounts of material, often can not be economical at all. To avoid this, customers tend to take orders for double, triple.. quantities than the ones they really need. To help to the benefit of our customers who purchase large amounts of concrete for storage and immediate disposition in following repairs:

TEIDE REFRACTORY SOLUTIONS, S.L. has developed special refractory concrete “ANTI-AGING” that allow to minimize the exposed problems by the most modern technology. COMPARISON: STANDARD CONCRETE against our ANTI-AGING CONCRETE Hemos sometido ambos tipos de hormigones a un envejecimiento acelerado bajo las condiciones siguientes:

We have tested both types of concrete to an accelerated aging process under the following conditions:

• Environmental Conditions: 97% humidity

Temperature: 25ºC

Exposure time: 30 días.

These have been the RESULTS obtained:

| | Setting -Initial | Setting -Final | CompressionResistance | Weight Increasing(sample of the bag) | Comments | |---------------------|:----------------:|---------------:|-----------------------|---------------------------------------|-----------------------| | CONCRETE STANDARD: | 10 hras | 14 hras | 205 kg/cm² | 3,50 % | Formación de hidratos | | CONCRETE ANTI-AGING : | 6 hras | 8 hras | 555 kg/cm² | 1,20 % | Aceptable |

**TO BEAR IN MIND:: **

• It is not enough carrying out tests in setting. The results do not indicate decisively if the concrete has aged.
• Look for the contents of the bags. Check for lumps .
• Perform preliminary tests of compression strength and curing.

TELL US IF YOUR CONCRETE WILL HAVE TO BE LONG TIME IN STORAGE (more than 4-6 months) and/or in a high humidity environmental and WE WILL PERSONALIZE OUR FORMULATION TO YOUR REQUIREMENTS: AA (ANTI AGING)
