Material for ribbon foundation. Work with dry soil. Cement mortar composition
Most of the low-rise dacha and country houses are constructed on a tape base. With all the material intensity and labor, this type of bases for buildings is greater popularity.
This promotes simplicity and speed of work. Also, the solution to build a ribbon foundation makes it possible to use the space of the basement under the garage or cellar.
Selection of material for a belt foundation
The most widely used material for ribbon foundations is concrete on a rubble base or concrete from butte stone. More easily for the construction of such structures, concrete blocks are used. As a variety, there is still a device from a brick (Zheleznyak). But there are big restrictions, it is suitable only for dry soils. The height of buildings, with such grounds there can be no more than two floors. Walls must be lightweight, wooden, frame-shield, or from foam concrete blocks.
The foundation is constructed in trenches or pit. Formwork is installed on the lined platform. Disassembly of which is made 20 days after the end of concrete work. The formwork is also necessary when the trench walls have a slope and exceeding the width of the foundation. You can fill the foundation without formwork if the walls have verticality. On the prepared base from the sand, the edge stone or rubble layers is stacked, it is well tumped and poured with cement mortar.
Cement mortar composition
The composition of the cement mortar for the fill of the boob stone depends on the composition and humidity of the soil. With dry soils, the ratio of cement and sand 1x8. When pouring concrete, the ratio of cement, sand, rubble 1x3x5. Wet soils require the use of a more rigid solution, for a large rubble or butt stone, the ratio of sand and cement 1x3, and for concrete foundations, the ratio of 1x2x4.
Work with dry ground
For small gardening houses with dry grounds, it is allowed to arrange ribbon structures from soil-cement mixtures or similar materials for the belt basement. For their preparation, I use ice and clay soils dug from a pit or trench.
For the preparation of the mixture, the soil is sieved through a metal sieve with small holes in 3-5 mm, fall asleep into the concrete mixer and mixed with cement in a ratio of 200 kg per 1 cube of soil. The mixture first stirred dry, then water is added. The finished mixture is placed by layers of 20-30 cm and tamper. The strength of such a foundation is achieved in a month. Periodically, within a month, the foundation should be moistened to a small amount of water. After this period, you can build walls. Best casino in India - bollywood casino
