Analysis Of The Technical Advantages Of Foamed Cement And Traditional Insulation Materials-Suzhou Anjia
As a new green building energy-saving material, foamed cement has a wide range of uses, such as: roof insulation, floor heating engineering, indoor and outdoor cushions, indoor and outdoor insulation, non-load-bearing walls, new energy-saving bricks, earthquake resistance, sound insulation and other construction engineering fields.
The country attaches great importance to environmental protection, and the construction industry follows closely behind. The research and development of new environmentally friendly building materials came into being. Traditional insulation materials are not ideal, and new building materials have good development prospects.
Foamed cement has many technical advantages compared with traditional insulation materials:
1. Stable thermal performance
The thermal conductivity of foam concrete is 0.06~0.16w/m, and the thermal resistance is large. The thermal conductivity of its products can be controlled by adjusting the proportion after calculation according to the design. The control process is simple and the performance is stable.
2. High intensity
Foam cement is a high-strength insulation material with a compressive strength of 0.25~1.50Mpa and a finished product density of 320~/m3. The strength and bulk density can be controlled by changing the raw material ratio according to engineering requirements, and the process is easy to control.
3. Low water absorption.
Foamed cement contains a large number of independent bubbles, which are evenly distributed and have low overall water permeability.
4. Low construction difficulty
Four people are required to operate each piece of foam cement on-site, and the daily output is 65 to 120 cubic meters. There is no need to occupy other supporting equipment and the construction speed is fast.
5. Good construction fluidity.
Foam cement has a unique liquid state and strong foaming properties. It has strong fluidity and can be pumped over long distances. It has strong injection capability and high degree of mechanization. Can be pumped with a hose and poured directly.
6. Long service life
The foam cement high-tech project has good integrity and is closely integrated with the main project. No boundary clearances and ventilation ducts are required. It has low elastic modulus and is not easy to hollow or crack. The service life is 50 years, which is basically the same as the main body life.
