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, आणि नंतर सिमेंटच्या स्लरीमध्ये फोम जोडणे, एकत्रित, मिश्रण, मिश्रण, आणि पाणी.

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. उदाहरणार्थ: foam concrete block, foam concrete lightweight partition wall, foam concrete cultural stone, foam concrete garden application, इ.

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

उदाहरणार्थ: backfilling (landfilling of garbage dumps, road and bridge applications, load-reducing filling of tunnel entrances, subway load-reducing filling, इ.), foam concrete cast-in-place walls, इ. Because foamed concrete has the characteristics of environmental protection, simple construction and operation, स्थिर गुणवत्ता, 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) थर्मल पृथक्: The thermal conductivity is 0.06-0.28W/(एम.के), and the thermal resistance is about 10-20 times that of ordinary concrete.

2) हलके: The dry bulk density is 300-1600KG/M3, which is equivalent to about 1/5 करण्यासाठी 1/8 of ordinary cement concrete, ज्यामुळे इमारतीचा एकूण भार कमी होऊ शकतो.

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) ध्वनी इन्सुलेशन: The cast-in-place foam concrete contains a large number of independent bubbles, आणि ते समान रीतीने वितरीत केले जातात. ध्वनी शोषण क्षमता आहे 0.09-0.19%, जे आहे 5 times that of ordinary concrete. It has an effective sound insulation function.

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

7) पाणी प्रतिकार: The cast-in-place foam concrete has low water absorption, तुलनेने स्वतंत्र बंद बुडबुडे आणि चांगली अखंडता, which make it have a certain waterproof performance.

8) टिकाऊपणा: मुख्य प्रकल्पाच्या आयुष्याप्रमाणेच.

9) साधे बांधकाम: only need to use cement foaming machine to realize automatic operation, can realize long-distance transportation with a vertical height of 200 मीटर, आणि कामाचा भार 150-300M3/कार्य दिवस आहे.

10) पर्यावरण संरक्षण: 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) अर्थव्यवस्था: Low overall cost.
