We have recently obtained the quality seal for the H-25 and H-30 Concretes from AENOR at our plants in Purchena and Huercal overa This means assuring the quality of our concrete by an independent entity that certifies that all products manufactured under the DOR (officially Recognized Document) seal are made under the most rigorous quality standards. The advantages for the customer who use our products are obvious. And we can highlight: Our concrete is a product with AENOR Mark, Quality Label Officially Recognized (D.O.R.) by the Ministry of Public Works according to article 81 of EHE-08. The advantages of this are indicated at the end of this text. AENOR offers the certified concrete user the possibility to consult the self-control and external control data (laboratory verification) of the concrete that is being used through the CERTHOR computer application, for which the concrete manufacturer must inform the user in the way Of access to said application, on its own initiative if the supply is greater than 1000 m3 and at the request of the client if it is less than said volume. Through CERTHOR it is possible to know the standard deviation of the concrete population (σ in the formula of the alternative acceptance criterion and if there has been any incidence related to the certification criteria that the concrete manufacturer must communicate to the client. The delivery notes that the manufacturer provides to the delivery of the product must be correctly marked with the AENOR logo and / or with the phrase “Concrete with AENOR Mark (D.O.R. according to EHE-08) The updated list of concrete with the D.O.R. Of AENOR can be found in the link:
If during the period of use of this concrete there is an incident related to its quality, detected in the on-site control during the supply, it will be very useful for the work to be informed of this to AENOR (e-mail address below) To examine and, where appropriate, initiate actions deemed appropriate.
ADVANTAGES ON DOCUMENTATION NEEDED PRIOR TO SUPPLY:

ADVANTAGES IN NUMBER OF TESTS REQUIRED IN CONTROL AT WORK DURING SUPPLY:
-Multiply by 5 the size of the lots
-Reduction of the number of controls according to the characteristic resistance
ADVANTAGES ON ACCEPTANCE CRITERIA FOR CONTROL LOTS:
| CONCRETE WITH D.O.R. AENOR CERTIFICATE | CONCRETE WITHOUT D.O.R. |
| –Identification control: xi ≥ fck
Alternative criterion (margin of acceptance), if the previous one is not met: xi ≥ 0,90 fck , y x̅ – 1,645 σ ≥ 0,90 fck |
– Estadistic control – No margin of acceptance
