I really need to have the maximum amount of information between these two main types of cement.Also, please give some examples of non - hydraulic and hydraulic cement.Thank you!
With all due respect NO grout at this point will hold up, and very likely answer number one has that notion? The issue is that Unless the pavers/slabs happen to be on an already solid surface, IE: a poured concrete base,,,they are subject to FLEX. I install and remediate thousands of sq. ft. of tile, very often those in a similar situation to what you describe, with grout constantly cracking, crumbling, and chipping out. Even the dry mix will at some point get WET, and set up, as though you mixed and poured it, but it won't remain solid in the paver joints forever. The better solution might be to remove the pavers, pour a slab and reset them. Steven Wolf
Hydraulic cements are materials that set and harden after being combined with water, as a result of chemical reactions with the mixing water, and that, after hardening, retain strength and stability even under water. The key requirement for this strength and stability is that the hydrates formed on immediate reaction with water be essentially insoluble in water. Most construction cements today are hydraulic, and most of these are based on Portland cement, which is made primarily from limestone, certain clay minerals, and gypsum in a high temperature process that drives off carbon dioxide and chemically combines the primary ingredients into new compounds. Non-hydraulic cements include such materials as (non-hydraulic) lime and gypsum plasters, which must be kept dry in order to gain strength, and oxychloride cements, which have liquid components. Lime mortars, for example, set only by drying out, and gain strength only very slowly by absorption of carbon dioxide from the atmosphere to re-form calcium carbonate through carbonization.
