How to make cement from wood ash

Primitive technology: How to make slag-base cement from wood ash! How to make a mortar that tightly sticks to the brick, to the metal and to other surfaces. This video shows the exact proportions of geopolymer concrete that our grandfathers used and which is now almost forgotten. THANKS FOR SUBSCRIPTION AND REPOST !!! #how to make Our grandfathers used this non-clay mortar (although clay was sometimes added for volume) for the putty of the furnace and possibly for laying bricks. This heat-resistant slag-alkaline concrete m 1000 with your own hands at home can be done very simply. The composition of this solution for the oven is very simple and it will be necessary to dilute it: ash, water, lime and salt. To make ash mortar for plastering the walls or for plastering the stove, it is necessary to stir the granule well to make it without lumps. The types, brand and classification of this building slag-alkali cement m1000 were described in their books by Glukhovsky Viktor Dmirtievich: Slag alkaline cements and concrete; Production of concrete and structures on the basis of slag binder; Handbook of precast technology. Soil silicates and grout cement. This building ash solution or geopolymer concrete can rightly be called Russian, since unlike clay, Portland cement and lime mortar, it is used only in Russia and now mostly only in some Siberian villages.

 The composition of the solution and its proportions (these are my personal proportions, other stove-makers do by eye or use other proportions): Wood or coal Ash - 6 kg, Salt -1 kg or NaCl, hydrated lime - 3 liters or calcareous milk and if you use lime paste then also water H2O. Preference is better to give wood ash, rather than coal. Although coal ash is also suitable. This geopolymer concrete or ash mortar adheres tightly to any surface, especially hot or well heated.
