It always amazes me when "so call experts" make statements like "Monky blood". It is insulting, evidence of ignorance and just what has perpetuated the inability of the flooring industry to resolve the excess moisture (RH and VT) issue. We will not at this point deal with the difference.

Now I will continue addressing those who really want knowledge on silicates. Concrete is a material that depends on Silicates to bind the aggregates together (CSH) Calcium Silcate Hydrate. Cement needs water to hydrate but this process is very inefficient. A useless hydrate that is left in concrete is Ca(HO)2 but if you can encourage this hydrate back into the hydration cycle you will produce more CSH.
This is accomplished, not with Meta Silicates alone but a skillful blending of xxzkxszty??? and silicates.

The process enables cement to hydrate like it is on streoids and this is termed the pozzolanic effect and from Roman times they did this very well with volcanic ash. Only a monkey would say Roman concrete used monkey blood although they did use bulls blood (nasty).

Water Glass!!! in other words Meta Silcate, very bad for concrete, why? only if this is employed as an unreacted silca, as you will end up with "concrete cancer". Concrete that will cause to debond any coating applied onto this surface, as hydrostatic vapour transmission from beneath the coating carries dissolved Ca(HO)2 and this will cause the coating adhesive distress and they will debond.

Freshly poured concrete which retains very high moisture content can also debond caotings if applied too soon. That is where ICD comes into play.

Some say they can stop this even if a meta silicate is embedded into the concrete surface but eventually the chemical reaction from the water bourne contaminants (either from the concrete itself or from the ground beneath the slab) will, not might but will break down the cement just under the coating overtime.

There are companies that sell in great quantities, pure "Meta Silicate solutions" as hardeners. Yes they are hardeners and yes they will react with the free lime and become themselves an integral part of the finished paste cover but very shallow into the upper layer of cement (steel trowelled) finished paste. This is where we get all the "Monkey Blood" hysteria about silicates, shame on these dooms day proclaimers.

ICD is silicates blended so as to fully integrate with the cement and water (yes your water is of equal importance to the cement) so as to produce from a OPC concrete a concrete that has about twice the CSH, with a densification like (virtual zero moisture permeability), like granite, we use the md (mille darcy) to confirm this. Cement that holds mix water longer (beyond 6 months) for extended controlled hydration but will release so little from the concrete that you can coat within days.

Best regards to those really listening.
