Material for the ribbon foundation. Working with dry soil. The composition of the cement mortar for filling
Most of the low-rise country houses and country houses are built on a ribbon foundation. With all the material intensity and labor costs, this type of foundation for buildings is very popular.
This is facilitated by the simplicity and speed of work. Also, the decision to build a ribbon foundation makes it possible to use the basement space for a garage or cellar.
Choosing the material for the ribbon foundation
The most widely used material for ribbon foundations is crushed stone concrete or rubble stone concrete. Less often, concrete blocks are used for the construction of such structures. As a variety, it can also be made of brick (ironstone). But there are big limitations here, it is suitable only for dry soils. The height of buildings on such grounds may not exceed two floors. The walls should be lightweight, wooden, frame-board, or made of foam concrete blocks.
The foundation is built in trenches or a foundation pit. A formwork is installed on the leveled area. The dismantling of which is carried out 20 days after the end of the concrete work. Formwork is also necessary if the trench walls are inclined and the width of the foundation is exceeded. It is possible to fill the foundation without formwork, if the walls are vertical. Rubble stone or crushed stone is laid in layers on the prepared sand base, well compacted and filled with cement mortar.
The composition of the cement mortar for filling
The composition of the cement mortar for pouring rubble stone depends on the composition and moisture content of the soil. In dry soils, the ratio of cement and sand is 1x8. When pouring concrete, the ratio of cement, sand, and crushed stone is 1x3x5. Wet soils require the use of a more rigid mortar, for large crushed stone or rubble stone, the ratio of sand and cement is 1x3, and for concrete foundations the ratio is 1x2x4.
Working with dry soil
For small garden houses with dry soils, it is allowed to arrange ribbon structures from cement mixtures or similar materials for a ribbon foundation. For their preparation, I use loess and clay soils excavated from a pit or trench.
To prepare the mixture, the soil is sifted through a metal sieve with small holes of 3-5 mm, poured into a concrete mixer and mixed with cement in a ratio of 200 kg per 1 cubic meter of soil. The mixture is first mixed dry, then water is added. The finished mixture is laid in layers of 20-30 cm and tamped. The strength of such a foundation is achieved in a month. Periodically, during the month, the foundation needs to be moistened with a small amount of water. After this period, walls can be erected. 1Win stands out by offering more than just standard bonuses — it provides a real opportunity to grow your balance significantly from day one.
