Today by production of construction jobs materials from reinforced concrete are widely applied. However long since in rural zone were in the construction course from eco-friendly local materials. The construction brick which can be made the hands also belongs to them. Such material can be used at construction of country house, garage, farm buildings. Knowledge of production of brick for the businessmen who are going to develop production of building materials will be useful.
Instruction
1. The easiest way of production of brick – bezobzhigovy pressing. Its advantage that it is eco-friendly and harmless. Except brick, pressing without roasting can be made tile, stone blocks, tile for facing of surfaces.
2. For high-quality production of brick by bezobzhigovy pressing it is required to provide the low moisture content and considerable preliminary clamping of material.
3. Process of drying of brick lasts about a week, at the same time the finished product has ability to self-warming up therefore in certain cases the brick is prepared for use in laying in one-two days. As binding materials cement or lime is used.
4. The amount of water has to be sufficient for ensuring durability of brick. The humidity of mix is defined by its compression in fist. It has to roll down in lumps, but not to soil hands. When using for production of brick of soil with high content of clay add ashes or sand to mix.
5. For test of soil take bucket without bottom and place it on plain surface. Soil should be filled in bucket several layers, each layer is rammed previously. The filled bucket is overturned on plain surface. If the cone sustained thus within ten days does not break, having fallen from height of one meter, then it is necessary to recognize soil as good.
6. Emergence of cracks on such sample testifies to soil fat content, and diffusion of soil says that he is lean. For adjustment add ashes, shaving or slag to greasy soil. Lean soil is enriched with clay. Heat conductivity of soil decreases addition of fibrous additives.
7. Mix is carried to pasty state and keeps within forms. The consistence has to be such that the form of timbering remained. The most widespread method of drying – natural. At the corresponding weather patterns duration of drying is from one week to one month. The best conditions for drying – draft in the presence of roof.
