Construction cost of roof thermal insulation foamed cement construction is detailed

  來源:www.woodsyend.com
We refer to our construction company to undertake the actual construction of the project, a set of data for your reference.
In general, the bulk density of roof insulation construction is controlled in 350-400 kg/m_and the average thickness is 8-10 cm.
1, 1 cubic foamed cement materials: about 6 bags of ordinary Portland cement (weight 50 kg/bag), foaming agent consumption can be controlled at 1 kg/m_;
2. Material cost accounting:
A. Ordinary Portland Cement at Market Price of 400 yuan/ton: 6 bags of cement *20 yuan/bag = 120 yuan
B. Foaming agent at the market price of 12 yuan/kg, 0.5 kg per cubic volume:
Foaming agent 1 kg *12 yuan/kg = 12 yuan, according to 12 yuan;
3. Necessary labor cost: According to our company's large output pumping machine, a total of 5 people are needed for the whole set of equipment, and the total labor cost for each cubic foamed cement is 4.5 yuan.
4. Water and electricity cost: According to our company's large output pumping machine, the total power of the whole set of equipment is 13KW, generating 1.5 yuan of water and electricity fee per cubic foamed cement.
5. Depreciation cost of equipment: According to our company's large output pumping machine design, under normal construction conditions, the depreciation cost for each cubic volume of foamed cement produced by the whole set of equipment is 2 yuan;
6. To sum up, the total cost per cubic foamed cement is 120+12+4.5+1.5+2=140 yuan.
If the bulk density is controlled at about 350 kg/m, the amount of cement used is 5.5 packs, which is 50 kg/pack.
According to our long-term construction experience, the thickness of roof thermal insulation foamed cement should not be less than 4cm in principle.
But the construction bulk density can be adjusted arbitrarily. If the powder of grade I and II fly ash is added to replace part of the cement and the amount of cement is replaced, the cost can be saved by 1/3 to meet the different requirements of heat preservation or pressure bearing.
At the same time, we sincerely welcome you to visit our company, Shunzhu Shangqi!
