The alkaliâsilica reaction (ASR) is a reaction which occurs over time in concrete between the highly alkaline cement paste and reactive non-crystalline (amorphous) silica, which is found in many common aggregates and sufficient moisture.his reaction causes the expansion of the altered aggregate by the formation of a swelling gel of calcium silicate hydrate (C-S-H). This gel increases in volume with water, and exerts an expansive pressure inside the material, causing spalling and loss of strength of the concrete, finally leading to its failure.

I did some research about the best way to take the stuff and actually called the company to make sure I was taking them correctly. It does not specify on the bottle if you take them both together or you take them twice a day. The guy I called at Predoxen.com said I could take them both at the same time if I needed. But the best way was to take them twice a day. One in the morning and one at night. He said I should try and take it on a regular schedule and to masturbate about a half hour after I take it or have sex with my girlfriend.
