Ash instead of cement: superalloy solution as stone. The exact proportions
It was the study and it was proven that the ash can be used in construction instead of cement. From it produce ash brick. Many ash is used as an additive in concrete. It is calcium oxide which has good cementing properties.
Reducing the consumption of cement - a huge plus in savings during construction. Ash is a filler that improves concrete structure formation. It is more environmentally friendly than Portland cement.
The strength of the mixture decreases, and vice versa. If used for brickwork, then disassemble the bricks would be impossible.
There forgotten technology. They are even better today.
How to replace the cement and make it out of the ordinary ash
This cement from the ash exceeds ordinary Portland cement. He superalloy and lasts for years. Make it quite possible at home. I do not need complicated ingredients.
The solution will become like a stone, dries quickly and adheres well to metal, stone, brick and others. surfaces.
Here's what you need:
- Ash - 6 liters (more suitable wood ash, but coal is also suitable)
- hydrated lime (Liquid like milk) 3-5 liters,
- usual salt - 1 kg.
Slaked lime should be diluted as you would normally do for whitewashing the walls. For example, 2.3 kg. 10 liters of water.
Sift the ashes, get rid of large debris (stones, etc.). It is also necessary to filter through a sieve lime.
Pour salt in ash and mix thoroughly with a spatula. The salt may take any (large or small).
Put on gloves. The basin of salt and ash pour lime. Add gradually to get both on density as ordinary cement. Knead solution.
Can plaster such solution, or putting him tile. Such a mixture of good gloss over the cracks in the stoves in the country or in the bath, fireplace, tandyr. The solution should be applied directly on a hot stove, because he is not afraid of high temperatures and the effect is much better.
Alternatively use solution - bedaub gap between the pipe and slate. To reduce shrinkage, add not a lot of fine sand in the mixture.
