I assume you mean cement and concrete.\n\nCement is the bonding agent used to make concrete mix.  In addition to cement, concrete is made of aggregate (gravel and rock) and water.  The formulas vary somewhat according to the application, and whether the concrete will be pumped when it is poured.  You should not have too much water in the concrete mixture because it will reduce the strength of the concrete when it is cured.  Many times a sample of the concrete is poured for laboratory testing at a later date.\n\nThe evaporation of water from the poured concrete must be controlled while it is curing for maximum strength.  This can be accomplished by spraying water on the surface several times a day.  The hotter the weather, the more frequently it should be wetted.  Alternatively, there are products available that make a moisture barrier to reduce evaporation when sprayed on the surface of the concrete.\n\nReinforcing steel (rebar) is used inside concrete structures to improve strength and reduce cracking.  Building codes may give guidance as to the quantity and placement of rebar, but sometimes a structural engineer should be consulted.  Wire mesh is commonly used for large flat areas, like a slab or sidewalk, but it is not very effective and rebar is preferred.\n\nCement is also used with sand and lime to prepare mortar for masonry (brick and concrete block), and for plastering and stucco.  When the mortar is to be used for ceramic tile, the sand is usually omitted.

there are these surveyor guys who examine soil to evaluate its potential for residential or commercial building. I'm not sure where to find them though...you might want to google or call a local contractor in your yellow pages.

Put Calcutta, India in your search box. It should put you into the City website. Than click on real estate. The companies will show up, then contact one of them.

I totally agree with the ACI answer.  \n\nCheck out companies that have Materials Labs.  Geotechnical engineering companies often have a materials lab and a special inspecting department too, they all go hand in hand. You can join APWA or ASCE to network.  They have monthly meetings all over the country.

I've been to the tropics...many of the homes i have seen are concrete, some are stilted, some are made of sticks tied together with tin roofs.....I have also seen fiberglass pods there. \n\nyou could try looking up real estate in different countries,\n\n(mexico, barbadoes, dominican republic..etc)

E.g. For cements. Calcium aluminates have very good step-wise hydratation properties.\n\nhttp://www.utexas.edu/research/cmrg/projects/CAC.html

YOUR DEALING WITH SALT WATER SO A DERIVITIVE WOULD BE ANTI AGRESSION TO THIS  SOME CONCRETE COMPANIES MAY HAVE THIS TRUE ANSWER\nANTI CORROSIVE PROTECTANT \nSEE IN FLORIDA WE USED A ALUMINUM BASED METAL BUT CHECK WITH THE CONCRETE MANUFACTURES IN YOUR AREA
