The scope of this building material is extremely extensive. But speaking with reference to the foundation of the structure, you will only have to specify for which construction it is being built? The answer to the fractions of the rubble for the foundation is quite short - enough for massive structures 20 to 40, enough 5-20 for low-rise construction( 1 - 2 tiers).
The figures denote the linear dimensions of the pellets, and the requirements for the material are determined by the corresponding GOST( and there are quite a few of them,for each type of product).But the information given is too simplistic an explanation on the topic of the article, and the benefits from it are few. At least because the assortment of rubble is large enough, and choosing, given the specifics of the application and the importance of such a constructive element of the building as a foundation, you still need the best option.
Kind of rubble
This material is categorized according to the raw materials used in production. The most solid is granite, but its cost does not clearly fall under the definition of "budgetary construction."It is advisable for an individual builder to focus on the gravel variety of products, it is cheaper. For a residential 1 - 3 storey house made of brick or reinforced concrete it is quite suitable. And in the case of erection of light buildings( for example, wireframes, of cellular concrete), a cheaper crushed stone, limestone, is also sufficient.
ASedness
Hearing this term, very few people understand what is at stake. If it is "decrypted", then this is nothing more than the "degree of plane" of the granules. The products are obtained by crushing various rocks, hence, the fractions have different shapes - like triangular pebbles, needle-shaped, plate-like, and so on. On this basis, crushed stone is divided into 4 categories. From the practical point of view, the cube-shaped granules are better suited for the foundation. Pros - it is more convenient to rammer, and strength is higher.
Conclusion
For the construction of a private dwelling house , the optimal version of gravel is gravel( or lime) with granules from 5 to 20 mm, cuboidal, grades 1,200-1,400 .And factions should be different. In this case, the compaction of the filled solution will be more qualitative, hence, there will be less voids in its structure. Hence, the artificial stone will acquire the characteristics necessary for the foundation( first of all, strength).
