what are  the properties of silicate grouted clay?

i only know that you have to use the grout with sand made into it. that silcone stuff won't work well on clay and ceramic tile.

i'm not exactly sure, but i would think that it would depend on the soil composition.  after all a fine clay has much different properties than a sandy or rocky soil

Generally speaking if you mixed the GERU completely with your usual clay, it is coloring.  A top coating would be considered as glazing by most (and for terracotta, the color must extend throughout and not just be on the surface).\n\nMost stoneware is made entirely of Geru clay.  This is part of the expense of making the items.

Your question is way to vague.  There are so many variables to consider that there is no way to answer your question.  \n\nWhat kind of deposite is it?  Is it near surface or very deep?   What kind of other minerals are there?  What kind of permiting is required.  Is it an enviromentaly sensitive area, or in existing workings?  What kind of impurities are involved?  \n\nA feasability study is your first step.

depends upon the situation, if you have a confined or unconfined aquifer.\n\nPermeability\ndensity and viscosity of the liquid in the aquifer\n\nTransmissivity\nT = K*b\nK = hydraulic conductivity\nb = saturated thickness of aquifer\n\nStorativity\nconfined\nS = Ss*b\nSs = specific storage\nb = saturated thickness of aquifer\nunconfined\nS = Ss*b + Sy\nSy = Specific yield\n\nThis is only the basics a good Hydrogeology would help if you need more or browse the internet, lots of info out there.

Wyoming bentonite is composed essentially of montmorillonite clay, also known as hydrous silicate of alumina. In more simplistic terms, the structure of bentonite is much like a sandwiched deck of cards. When placed in water, these cards or clay platelets shift apart. Bentonite attracts water to its negative face and magnetically holds the water in place. because of this unique characteristic, Wyoming bentonite is capable of absorbing 7 to 10 times its own weight in water, and swelling up to 18 times its dry volume.

In general, the more clay in the soil, the higher the cation exchange capacity, the greater the rates of expansion (i.e. greater rates of saturation).\n\nMontmorillonite would expand quikcer because it has the highest cation exchange capacity of all the 2:1 lattice clays.  This higher cation exchange capacity allows for the clay minerals to bond quickly with water or with base cations present, therefore expanding quicker than vermiculite which has a lower cation exchange capacity. \n\nHowever, a vermiculite that is not saturated with base cations will expand quicker than a montmorillonite that is saturated with base cations.  If neither is saturated, the montmorillonite will expand quicker because of its greater cation exchange capacity.\n\nMontmorillonite clays mixed in with soil will be far more fertile than vermiculite mixed in with the soil.  However humus has an even higher cation exchange capacity than both montmorillonite and vermiculite.

hardness, luster, clevage, composition, crystal structure\n\niron is useful also in the mineral gypsum they use it to make drywall\n\nmost gems are valueable because they form extremely slow making them rare, they are also the very hardest type of mineral

Concrete has limestone,calcium crystals etc,so even if you heat it at high temp or low or leach it ,transparency won't happen.\n  But, optimally cooled resin is transparent and can be used to set biological preserves , infrastructural support etc, but cant be used for large structures.The acid test lies in at which rate you cool it.

If you are asking what are the minerals that are most resistant to weathering, I can give you some help. How fast any particular mineral actually moves through the rock cycle is hard to answer, since it really depends on the setting.  In general the deeper a mineral forms (higher pressure and temperature) the more unstable it is at the surface. Quartz and muscovite are two of the more stable minerals. \n\nHere's some chemical weathering rates:\nMean lifetime of 1 mm or fresh rock (Nahon, 1991)\nRock Type................ Climate..................... Lifetime (years) \nAcid rocks...............tropical semi-arid.......... 65 to 200\n..................................tropical humid........................ 20 to 70\n..................................temperate humid........................ 41 to 250\n.................................. cold humid.................... 35 \nMetamorphic rocks..... temperate humid..........33 \nBasic rocks.................... temperate humid.........68\n..........................................tropical humid.............. 40

Unexpanded or raw perlite has a specific gravity of around 1.1 g/cm^3, or slightly more dense than water.\n\nPerlite is unusual in that it contains a lot of water in its composition, and when heated it expands like puffed wheat.\n\nWhen it is expanded, perlite has a density of 0.03 to 0.15 g/cm^3, or considerably less dense than water.  Expanded, it makes a pretty good thermal insulator.  \n\nIn horticulture it fills soil area and makes it more open to air, while still retaining considerable water.  In this application it is also known as vermiculite.\n\nFor more info about perlite, check out this website: http://www.perlite.info/indexes/main.html

You are looking for a plasticine clay.  It does not get hard and is very maliable.

I believe it's clay, softer not as grainy, and it clings better.
