I need more details about alkaline activator preparation for geopolymer concrete , specially the calculating the molarity of alkaline activator ? [3][4], Sodium oxide is produced by the reaction of sodium with sodium hydroxide, sodium peroxide, or sodium nitrite:[5]. 10 years ago. The best is to use table in excel to make the calculations. Though I have developed technique for quantitaive determination of NaOH, Na2CO3 and NaHCO3 in a composite mixture I am not able to distinguish Na2O and NaOH. He also says that alkali activation will give more strength but the concrete is suspicable to chemical attack and corrosion. These changes arise because the silicon dioxide and soda have reacted to form sodium silicates of the general formula Na2[SiO2]x[SiO3]. need explanation how to find the ratio of Si/Al in geopolymers,and what are the parameters needed for this estimation. How can I dissolve sodium silicate in water? His question in solid solution and not aqueous solution (Solid mixture). If possible please provide calculations. The Life Cycle Assessment (LCA) method comprises the compilation and evaluation of inputs, outputs and environmental impacts of a product during its life cycle. Typically, manufactured glass contains around 15% sodium oxide, 70% silica (silicon dioxide) and 9% lime (calcium oxide). The nonsense calculation (IMHO) is easy to carry out: Molecular mass of NaOH is 39.997g/mol Thus, 2 X NaOH = 79.994. The question is: when you mix the NaOH with sodium silicate and heat them to get dry solid mixture (No water), then, what is the percentage of Na2O in this mixture? As sodium silicate solutions do not have a fixed composition, you need to know the ratio between Na. In the previous question I forgot to multiply the last answer with 100 %. I am using sodium hydroxide from Sigma-Aldrich in pellet form. In this motif the positions of the anions and cations are reversed relative to their positions in CaF2, with sodium ions tetrahedrally coordinated to 4 oxide ions and oxide cubically coordinated to 8 sodium ions. The best is to use table in excel to make the calculations. PS: Be aware of w% or mol %. I would also add to the argument that what you obtain is not necessarily Na. How much grams NaOH is used to prepare the NaOH solution. Soda glass has a much lower melting temperature than pure silica, and has slightly higher elasticity. Join ResearchGate to find the people and research you need to help your work. The test results shown here also demonstrate the technical capabilities of this group of materials in potential bulk applications, such as concrete. The alkali metal oxides M 2 O (M = Li, Na, K, Rb) crystallise in the antifluorite structure. Become a Patron! is this true? How can you determine NaOH and Na2O in presence of each other where the quantity of each is restricted to a few miligram level (2 to 20 mg )? Using triple-detection GPC to study the aging of polyamide/nylon 12 in Selective Laser Sintering. Molar Mass of Na2O Oxidation State of Na2O. A more accessible way of producing it in the laboratory consists in decomposing the sodium salt of ascorbic acid at temperatures over 209 Celsius degrees. From each gram NaOH you will have 0.774794 grams Na2O ( from 2NaOH->Na2O+H2O).Then convert to %. Burning sodium in air will produce Na2O and about 20% sodium peroxide Na2O2. hope this helps. The results of this analysis are used to select alternative products or processes for a particular application. Most of these reactions rely on the reduction of something by sodium, whether it is hydroxide, peroxide, or nitrite. The alkali metal oxides M2O (M = Li, Na, K, Rb) crystallise in the antifluorite structure. From each gram NaOH you will have 0.774794 grams Na2O ( from 2NaOH->Na2O+H2O).Then convert to %. Yes, you are right. This is only calculations to find how much the percentage of Na2O in the fromula NaOH. All rights reserved.

How to fix or calculate Na2O (sodium oxide) content in a mixture of sodium silicate and sodium hydroxide with known solid contents? Synthesis. The test results shown here also demonstrate the technical capabilities of this group of materials in potential bulk applications, such as concrete. 1 Answer Manish Bhardwaj Jul 1, 2014 This is a typical stoichiometry question.To answer this question you want to get a relationship between #Na_2# O and NaOH. It is used in ceramics and glasses. He is saying that there is a difference between alkali activation and geopolymerisation. Flemish Institute for Technological Research, It is impossible to calculate the wt% of sodium in the example given, as information is lacking. Reaction Type. For example; 8%, 10% and 12%. I recently started to read works of davitavids. Sodium silicate - the weight % of Na2O in the water glass- usually about 10%. Reactants. I did it again, so the answer of your question will be as follows: 1) The % of SiO2 in Na2SiO3 = 100 % - Na2O % = 100 % - 50.8 % = 49.2 %, So if you have 10% Na2SiO3 with 90% NaOH, the % of SiO2 in this mixture = (10.0 % x 0.492) + (90.0 % x 0.0) = 0.0492 % + 0.0 % = 0.0492 x 100 % = 4.92 %, But if you have 10% NaOH and 90% Na2SiO3, the % of SiO2 in this mixture = (10.0 % x 0.0) + (90.0 % x 0.492) = 0.0 % + 0.443 % = 0.443 x 100 % = 44.3%. What is the difference between geopolymer and alkali activated cement? Sodium oxide is a solid ceramic (ionic bonded) that is very reactive. Unsupported or aging technology presents business-critical risks to continuity, productivity and output in today’s fast-moving, high-tech laboratory environments where skills and practices have changed dramatically in recent years. You can register for free and you will be able to login. If you take the "Calculate ratios of the activating solution" module, you can put in the composition of the silicate solution you have and add the amounts (NaOH pellets or solution) you want to mix and calculate the composition.
