The cost effectiveness of the new composite self insulating block

Self-insulating block refers to the wall structure that can meet the requirements of the current national and local energy-saving building standards without passing the thermal insulation technology of the interior and exterior walls.

The self-insulating block consists of three structural forms: the main block of the hollow structure, the insulation layer, the protective layer and the connecting main body through hole and filling. According to the specific requirements of different buildings, through the corresponding settings of adjustable parameters such as insulation layer material, thickness, thickness and fine aggregate varieties and ratios, cross-sectional structure and number of insulation connection pins, various technical indicators are adjusted to meet the market demand to the greatest extent.

Features of self-insulating blocks.

1. Excellent thermal insulation performance.

2. Light weight and high strength: density 600-800kg m?Compressive strength.

Achievable. 3. Small water absorption and low shrinkage: moisture content.

For the water absorption rate and the drying shrinkage rate, the wall can be avoided hollowing.

Cracking, water seepage and other common problems in the quality of block walls.

4. Good freeze-thaw resistance: after 25 freeze-thaw cycles, the mass loss is 10%, and the strength loss is 10%, which is better than that of common aerated concrete blocks.

and light aggregate concrete insulation blocks.

5. Excellent fire performance: the exterior is high-performance dense concrete, and the interior is filled with inorganic foam concrete.

and flame retardant foam boards.

Excellent fire performance, no fire hazard.

6. The construction process is simple and easy to promote and apply: there is no need to do auxiliary thermal insulation treatment, the construction process is simple, and it is easy to promote and apply.

7. Reduce the project cost: the exterior wall project does not need to do other thermal insulation treatment, which reduces the process and reduces the project cost.

Composite self-insulating block is aimed at the current development of the new wall material industry, with high-performance concrete hollow block as the shell, filled with lightweight insulation materials such as foam concrete or polystyrene foam in its hole imitation cavity, and the concrete block block integrating building enclosure and thermal insulation function is formed by injection molding of the block shell and insulation material into a whole through the production process, with excellent comprehensive performance such as light weight and high strength, thermal insulation, sound absorption and sound insulation, simple construction and low cost.

The self-insulating block is composed of three parts: one part is an ordinary concrete hollow shell, and the size of the hail is 400 600mm 200 300mm 200 250mm (length, width and height); the other part is inorganic foam concrete insulation material, which plays the role of thermal insulation, sound absorption and fire resistance; There is also a part of polystyrene foam board, which mainly plays the role of reducing its own weight, heat preservation and heat insulation; Foam concrete and polystyrene foam plastic board are organically combined with the concrete shell through a special interface bonding process to form the same whole. The self-insulating block has a simple appearance and is easy to process and produce, and the notch design at the end of the block effectively blocks the thermal bridge and increases the thermal performance of the block material.

Four advantages of concrete composite self-insulating blocks:

1. It has the same life as the building.

It can be built into a wall separately, which solves the integrity and weather resistance of the building insulation wall, so that the service life of the wall insulation system can truly achieve the same life as the building and solve the worries.

2. Eliminate fire hazards.

**The fire of the TV station, the fire of Jinan Lingxiu City, the fire of Jinan Olympic Sports Center, and the source bend fire of Nanjing's 50-storey high-rise building are all caused by the current thin plastered exterior wall external insulation materials.

3. Reduce construction costs.

1) Aerated concrete is 160 yuan per cubic meter, and the cost per square meter is 32 yuan.

2) 70 yuan per square meter for external wall insulation.

3) To sum up, the current practice costs 32 + 70 = 102 yuan per square meter of wall.

4) Self-insulating blocks are 450 yuan per cubic meter.

5) 5 square meters of masonry walls can be built per cubic meter, and the cost per square meter is 90 yuan.

6) The use of self-insulating blocks can save 12 yuan per square meter compared with the traditional practice.

4. Save construction time.

The original external wall insulation requires at least one month of construction period, and the use of high-performance concrete self-insulation blocks can directly enter the decoration without the need to do external wall thermal insulation.
