Voordele van ingegooide skuimbeton

What is cast-in-place foam concrete?

Gegote skuimbeton verwys na 'n liggewig skuim wat gemaak word deur fisies 'n waterige skuimmiddeloplossing voor te berei, en voeg dan die skuim by 'n suspensie gemaak van sement, aggregate, bymiddels, bymiddels, en water.

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. Byvoorbeeld: foam concrete block, foam concrete lightweight partition wall, foam concrete cultural stone, foam concrete garden application, ens.

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

Byvoorbeeld: backfilling (landfilling of garbage dumps, road and bridge applications, load-reducing filling of tunnel entrances, subway load-reducing filling, ens.), foam concrete cast-in-place walls, ens. 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) Termiese isolasie: The thermal conductivity is 0.06-0.28W/(M.K), en die termiese weerstand is omtrent 10-20 keer dié van gewone beton.

2) Liggewig: The dry bulk density is 300-1600KG/M3, which is equivalent to about 1/5 aan 1/8 of ordinary cement concrete, wat die algehele las van die gebou kan verminder.

3) Integriteit: 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) Klankisolasie: The cast-in-place foam concrete contains a large number of independent bubbles, en hulle is eweredig versprei. Die klankabsorpsiekapasiteit is 0.09-0.19%, wat is 5 keer dié van gewone beton. It has an effective sound insulation function.

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

7) Water weerstand: The cast-in-place foam concrete has low water absorption, relatief onafhanklike geslote borrels en goeie integriteit, which make it have a certain waterproof performance.

8) Duursaamheid: dieselfde as die lewe van die hoofprojek.

9) Eenvoudige konstruksie: only need to use cement foaming machine to realize automatic operation, can realize long-distance transportation with a vertical height of 200 meter, en die werkslading is 150-300M3/werkdag.

10) Omgewingsbeskerming: 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) Ekonomie: Low overall cost.
