How do you make refractory concrete?
Ingredients: River gravel or crushed fire bricksSandCalcium Aluminate cement. (if available in different grades choose the better one)Lime (lime is usually cheaper, about 80% of the cement price)WaterYou can add into this mix a little standard Fireclay if you like. Mixture: (parts ratio is 3 x 2 x 2 x 0.5, plus water)3 shovels of the gravel or crushed firebricks2 shovels of sand2 shovels of the (portland) cementhalf shovel of limeThis amount will require approximately 6-7 liters of water to mix the concrete. Put dry gravel and sand on a thin metal or plastic sheet, or on a clean concrete surface in an area you can make a bit dirty. (Be sure to clean the area and tools with water after working with cement.)Add the cement and lime on top of the gravel and sand.Calcium Aluminate cement and Lime will work the best as the cement in hot cooking conditions- This applies to refractory concrete as well as to heat resistant mortars.(Lime is sometimes mixed into fire clays. This is mixed like a normal cement based mortar, but with half the cement replaced with the lime. The cement holds it together when it is drying but when the heat gets into the cement and burns it out, the lime holds it all together. Lime used in building - calcium hydroxide Ca(OH)2 [oxide of calcium CaO of limestone] is used for making mortar and cement.)Ingredients in the now days Portland cement are:60% to 67% CaO17% to 25% SiO23% to 8% Al2O3up to 6% Fe2O3plus can contain also mini amount of MgO, MgSO4, Na2O, and K2O
How does cement and concrete cause global warming?
When calcium carbonate is thermally decomposed to make cement, it produces lime and carbon dioxide. Carbon dioxide is a major greenhouse gas causing global warming. 900 kilograms (almost one tonne) of carbon dioxide are emitted for every tonne of cement manufactured. The cement industry is responsible for about 5% of all carbon dioxide emissions.
What is lime saturated factor or LSF?
It's actually called the Lime Saturation Factor and it is one of three quality control factors used in cement manufacture. It represents the amount of lime (CaO) required to completely react with all of the silica (SiO2), alumina (Al2O3) and iron oxide (Fe2O3) in a cement kiln to produce the hydraulic minerals required for cement to set properly. It's formula is;- LSF = (100 * CaO)/(2.8 * SiO2 + 1.18 * Al2O3 + 0.65 * Fe2O3) The other two factors used to control cement clinker quality are;- Silica Ratio (S.R.) = SiO2/(Al2O3 + Fe2O3) and Alumina Ratio (A.R.) = Al2O3/Fe2O3 Regards, Ted.
