Foam concrete blocks are rather popular construction material. And it is quite explainable. Construction from foam concrete blocks is eco-friendly, economic and convenient. Besides, foam concrete blocks prevent heat waste and regulate humidity indoors. Quite possible to make laying from foam concrete blocks with own hands since they have rather small weight and easily give in to processing.
Instruction
1. Lay out the foam concrete blocks intended for laying on pallets over base tile. It is recommended to unpack foam concrete blocks just before the beginning of laying.
2. Attentively examine all foam concrete blocks. If necessary clean their dirt, ice and dust. The foam concrete blocks having defects and chips need to be subjected to machining.
3. Lay the first row of foam concrete blocks. It is necessary to remember that it has to be laid on waterproofing layer. Prepare solution from cement and sand in proportion 4:1. Also it is possible to add softeners to solution. Lay out two layers of roofing material or other waterproofing material on sand-cement slurry. The basis of the first angular foam concrete blocks is recommended to be moistened with water for the best coupling.
4. It is necessary to consider that thickness of the first seam should not be more than 30 mm. When laying it is necessary to watch closely that in seams emptiness were not formed. You apply glue or solution with the special toothed palette ladle and you watch that all vertical and horizontal joints have been completely filled.
5. Take construction level and check all roughnesses of the first laid row of foam concrete blocks. Remove all defects by means of the grinding tool.
6. Lay out the subsequent ranks of foam concrete blocks. For increase in stability of wall and additional protection against cracks the laying from foam concrete blocks is recommended to be reinforced. For this purpose cut in foam concrete blocks by means of stroborez or the Bulgarian of groove and put in them armature.
7. Make overlapping. It is necessary to consider that overlappings cannot be stacked directly on foam concrete blocks since at the same time there can be dot loading exceeding ultimate strength of this material. Cast monolithic concrete armopoyas 10-20 cm high and lay it over laying. Lay overlapping on the reinforced belt. In addition warm belt.
8. At wall construction it is necessary to do of foam concrete blocks of overlapping of door and window openings by means of special blocks of U-shaped form.
