Liejamo putų betono privalumai

What is cast-in-place foam concrete?

Liejamas putų betonas – tai lengvas putplastis, pagamintas fiziškai paruošus vandeninį putojančio agento tirpalą, o po to putas supilkite į suspensiją, pagamintą iš cemento, agregatai, priemaišų, priemaišų, ir vandens.

The application of cast-in-place foam concrete can be divided into two categories:

1. Cast-in-place foam concrete is mainly made of products. Pavyzdžiui: putų betono blokas, foam concrete lightweight partition wall, foam concrete cultural stone, foam concrete garden application, ir tt.

2. The cast-in-place foam concrete is mainly cast on-site.

Pavyzdžiui: backfilling (landfilling of garbage dumps, road and bridge applications, load-reducing filling of tunnel entrances, subway load-reducing filling, ir tt), foam concrete cast-in-place walls, ir tt. Because foamed concrete has the characteristics of environmental protection, simple construction and operation, stable quality, and can be poured on-site. The foamed concrete poured on site is called cast-in-place foamed concrete or cast-in-place foamed cement.

1) Šilumos izoliacija: The thermal conductivity is 0.06-0.28W/(M.K), and the thermal resistance is about 10-20 kartų daugiau nei įprastas betonas.

2) Lengvas: The dry bulk density is 300-1600KG/M3, kuri prilygsta maždaug 1/5 į 1/8 iš paprasto cementbetonio, kurios gali sumažinti bendrą pastato apkrovą.

3) Integrity: On-site pouring construction is closely integrated with the main project, without boundary gaps and ventilation pipes.

4) Low elasticity and shock absorption: The porosity of cast-in-place foamed concrete makes it have a low elastic modulus, so that it has a good absorption and dispersion effect on impact loads.

5) Garso izoliacija: The cast-in-place foam concrete contains a large number of independent bubbles, and they are evenly distributed. The sound absorption capacity is 0.09-0.19%, kuri yra 5 kartų daugiau nei įprastas betonas. It has an effective sound insulation function.

6) Compressive resistance: The compressive strength is 0.6-25.0MPA.

7) Atsparumas vandeniui: The cast-in-place foam concrete has low water absorption, relatively independent closed bubbles and good integrity, which make it have a certain waterproof performance.

8) Patvarumas: the same as the life of the main project.

9) Simple construction: only need to use cement foaming machine to realize automatic operation, can realize long-distance transportation with a vertical height of 200 metrų, ir darbo krūvis 150-300M3/darbo diena.

10) Aplinkos apsauga: The raw materials required for foamed concrete are cement and foaming agent. The foaming agent is neutral and does not contain harmful substances such as benzene and formaldehyde, which avoids environmental pollution and fire-fighting hazards.

11) Ekonomika: Low overall cost.
