And now facing some of rubble stone laid! I strip the last seam and began construction of the formwork on the inside of the house for the device monolithic cap.
Laid-stone will serve as the outer shell and generally will result from a single piece construction rubble and concrete.
Since the basement of the building is very vulnerable point of the structure and exposed to intense rainfall: spray water, soil moisture, mechanical stress, then the design shall ensure reliable operation over a long time.
Given the above, by pouring a concrete base I used M250-300 manual preparation (batch produced in the bath, and a concrete mixer).
Mixture proportions:
- 1 part cement;
- 1.7 parts sand;
- 3 parts gravel (fractions 5-20);
- 0.7-0.8 parts water;
- plasticizer-3 (application recommendations on the packaging).
water is sometimes added above normal for better mobility of the concrete mix, as it was necessary to fill all the pores and the concavity of the masonry.
Reinforcement made of reinforcement rods 4 to 14 mm., Two at the bottom, two at the top.
Pouring concrete made with the joint use of rubble, that in the future the reliability of the design clearly worse not affect !!!
All work is done alone, without aides. It was necessary to separate construct into sections (blocks), as for Day 7 cubic meters of concrete and knead bed is not realistic. In one working day was prepared to pour from 1.5 to 2 cc. m.
After 4 days of this milestone has been met. As the weather was hot, spilling concrete water held 2 times a day, and then hid the whole plane with plastic wrap.
After another 4 day formwork was pulled.
The construction season is coming to an end, sometimes at night the temperature dropped already to +2... + 4 ° C. According to the plans I had to backfill the trench with sand for floors on the ground and freeze construction until next spring ...
