Lightweight Concrete Additives | High-Performance Foaming Agents for Cellular Concrete
What is cast-in-place foam concrete?
Cast-in-place foamed concrete refers to a lightweight foam made by physically preparing an aqueous foaming agent solution, wobva wawedzera furo kune slurry yakagadzirwa nesamende, aggregates, zvinosanganiswa, zvinosanganiswa, uye nemvura.
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. Semuyenzaniso: foam concrete block, foam concrete lightweight partition wall, foam concrete cultural stone, foam concrete garden application, etc.
2. The cast-in-place foam concrete is mainly cast on-site.
Semuyenzaniso: backfilling (landfilling of garbage dumps, road and bridge applications, load-reducing filling of tunnel entrances, subway load-reducing filling, etc.), foam concrete cast-in-place walls, etc. 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) Thermal insulation: The thermal conductivity is 0.06-0.28W/(M.K), uye kupikisa kwekupisa kuri pamusoro 10-20 times that of ordinary concrete.
2) Lightweight: The dry bulk density is 300-1600KG/M3, izvo zvakaenzana ne about 1/5 ku 1/8 of ordinary cement concrete, which can reduce the overall load of the building.
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) Sound insulation: 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%, which is 5 times that of ordinary concrete. It has an effective sound insulation function.
6) Compressive resistance: The compressive strength is 0.6-25.0MPA.
7) Kuramba kwemvura: The cast-in-place foam concrete has low water absorption, zvakazvimiririra zvakasununguka mabhubhu akavharwa uye kuvimbika kwakanaka, which make it have a certain waterproof performance.
8) Kugara kwenguva refu: 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 mamita, and the workload is 150-300M3/working day.
10) Kuchengetedza kwezvakatipoteredza: 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) Economy: Low overall cost.
Cie-China.org ndiyo inotungamira furo kongiri yekuwedzera inopa inopa kongiri inopupuma mumiriri, superplasticizer,foam kongiri simba rekusimudzira kune lightweight kongiri, CLC inovhara. Kana uri kutsvagafoaming agent, ndapota inzwa wakasunungukataura nesu.
