[REQUEST] CEN/TR 16142:2011; CEN/TR 16349:2012 and CEN/TR 16369:2012

[ir_71]

Dear friends,

I'm looking for several documents (technical reports) issued by CEN, as follows:

1. CEN/TR 16142:2011 Concrete - A study of the characteristic leaching behaviour of hardened concrete for use in the natural environment

2. CEN/TR 16349:2012 Framework for a specification on the avoidance of a damaging Alkali-Silica Reaction (ASR) in concrete

3. CEN/TR 16369:2012 Use of control charts in the production of concrete

I'll be very thankful if someone who has them or some of them, or someone who is able to find this reports - shares them with me.

Thanks in advance,
I.R.
