how many tons of clinker are needed for producing 1 ton of cement ?
553454
Different companies use different formulas but generally cement is about 98% clinker.  In other words, 98 tons of clinker produces about 100 tons of cement.

By unit volume, probably dry cement is heavier. Why? Because rocks are heavier than water.

Portland cement needs about 28% w/w water for complete hydration. If you have mixed extra water without any suitable water absorbant material, some of it will separate out as free water, while rest may remain entrapped in the cement. It all depends how much extra water has been added.

Portland cement is the most common type of cement in general usage, as it is a basic ingredient of concrete, mortar and most non-specialty grout. It is a finely-ground powder produced by grinding Portland cement clinker (more than 90%), a maximum of about 5% gypsum which controls the set time, and up to 5% minor constituents (as allowed by various standards). As defined by the European Standard EN197.1, Portland cement clinker is a hydraulic material which shall consist of at least two-thirds by mass of calcium silicates (3CaO.SiO2 and 2CaO.SiO2), the remainder consisting of aluminium- and iron-containing clinker phases and other compounds. The ratio of CaO to SiO2 shall not be less than 2.0. The magnesium content (MgO) shall not exceed 5.0% by mass. (The last two requirements were already set out in the German Standard, issued in 1909). Portland cement clinker is made by heating, in a kiln, an homogenous mixture of raw materials to a sintering temperature, which is about 1450 °C for modern cements. The aluminium oxide and iron oxide are present as a flux and contribute little to the strength. For special cements, such as Low Heat (LH) and Sulfate Resistance (SR), it is necessary to limit the amount of tricalcium aluminate (3CaO.Al2O3) formed. The major raw material for the clinker-making is limestone (CaCO3). Normally, an impure limestone which contains SiO2 is used - the CaCO3 content can be as low as 80%. Secondary raw materials depend on the purity of the limestone. Some of the secondary raw materials used are: clay, shale, sand, iron ore, bauxite, fly ash and slag. When a cement kiln is fired by coal, the ash of the coal becomes a secondary raw material.

In the US, air conditioning units were often rated in tons of cooling.  An air conditioner that is rated at one ton has sufficient cooling capacity to produce one ton of ice (2,000 lbs) in twenty-four hours.  The rating is equivalent to the amount of Btu's that must be removed to convert a ton of water to ice.  Small air conditioners are usually rated more directly in Btu per hour, etc.  All units can be rated in tons based on engineering calculations (even though they do not actually make ice) to permit comparison with a building's heat load.  The manufacturer would not know how much air you wish to cool by how many degrees temperature change.  Since pure water weighs 62.4 lbs per cubic foot, 2,000 Lbs equals about 32.05 cubic feet which equals about 0.907 cubic meters.  Of course, air conditioners may be rated differently in countries that use the metric system.

Many jurisdictions allow a maximum weight loading per axle for commercial vehicles.  When a concrete (cement is the powder that glues concrete together) truck is fully loaded 9 to 10 yards, it will typically exceed the maximum allowable load.  The extra wheels are called a dolly.  These are hydraulically operated wheels that help spread the load onto another axle and therefore bring the truck into compliance with axle loading limits.  When the load is delivered and the truck is empty, the extra axle is raised to help reduce the turning radius of the truck.

The general rule of thumb in the Deep South of the USA is 1 ton of AC for every 600 square feet of space with an 8-10ft ceiling.\n\nYour room has a volume of 86.8 cubic meters.\n\n1 cubic meters = 35.3146667 cubic feet\n\nso your volume is 3065.25 cubic feet.\n\n1 ton is recommended for 600 sq.ft X 10ft = 6000 cubic feet.\n\nSince you have about half of that then 1/2 ton would probably do the trick.  A ton = 12,000 BTUH so 1/2 ton = 6000ft.\n\nI would recommend you get 9000BTUH to help handle the extra load from no insulation and the excessive temperature rise.  Since you don't have to worry about humidity in the desert, then oversizing the A/C shouldn't be a problem as it would be in a place with high humidity.\n\nGood luck!

When referring to bombs, tons refers to the bomb's explosive power, not the weight.  700 tonnes is pretty impressive for a non-nuclear bomb, but a nuke can easily get into the range of megatons.\n\nThe bomb itself is probably under 1-2 tons as far as weight is concerned.\n\nedit - just for clarity, one ton of explosive power means it is equivalent to one ton (weight) of TNT.  1 kiloton = 1000 tons of TNT; 1 megaton = 1,000,000 tons of TNT
