Hello,
I've been trying unsuccessfully to locate a 52,5 cement manufacturer in Saudi Arabia or UAE.
Can anybody enlighten me on the subject?.
Thanks in Advance.
Hello,
Has anybody used humidity sensors to keep mixed concrete Water/Cement ratios as constant as possible.
If so what do you recommend.
We use crushed limestone aggregate.
Best wishes
Hello,
I have a dark streak problem on my gray concrete panels.
It occurs from what I gather after rain. It seems that the panel is OK if it does not rain on it shortly after de-moulding.
The dark streaks seem to harden and it becomes almost impossible to remove them effectively.
In my opinion...
