Introduction

Different specifications

• The width of AAC panel is 600mm,the thickness is 50, 75, 100, 120, 150, 175, 200mm respectively, each piece of the length of 4-- 6 meters of large panel;
• The width of AAC panel is 600mm, Blocks with a width of 600mm, a maximum thickness of 200mm and a maximum length of 300mm;
• No steel reinforcement inside;

Different performance

(1) Bulk density

The bulk density of AAC panel is 600-650kg/m3; Block bulk density of 750-850 kg/m3;

(2) thermal conductivity coefficient

The thermal conductivity of AAC plate is 0.11W/m.K; Thermal insulation performance is 10 times that of concrete; 125mm thick AAC panel insulation performance is equivalent to 370mm thick clay brick wall; Because this material is a large plate, its performance is evenly distributed, and the overall insulation effect is better. Because the masonry blocks need to be treated with masonry mortar in use, their properties are greatly reduced, and the thermal insulation effect of block masonry distribution is greatly affected.

(3) sound insulation

AAC panel 100mm sound insulation index is 40.8dB because in the use of this material for large panel area up to 3.6 square meters per piece, so that its performance uniform distribution, the overall sound insulation effect is better. Because the masonry blocks need to be treated with masonry mortar in use, there are many blocks in the wall, which reduces the sound insulation performance, and the sound insulation effect of block masonry distribution is greatly affected.

(4) Bearing performance

AAC panel built-in steel mesh, bearing capacity and strength greatly enhanced; There is no steel mesh inside the aerated block, and its bearing capacity and strength are far less than that of AAC panel.

Whether the frame structure or the steel structure, because it belongs to the structure form of the whole installation of the large plate as the wall, it can adapt to the larger Angle displacement between the layers and make the seismic resistance greatly enhanced; Block belongs to the need for masonry and structural reinforcement as the wall material, the shock resistance is worse than the panel;

Different designs

(1) AAC panel is generally used on the inner partition wall with a thickness of 100mm, and its function can meet the requirements of sound insulation, fire prevention, heat preservation, etc.; aerated blocks are generally designed to be 200mm thick when used as the inner partition wall, and then thinner It needs to be processed before it can be used, and its stability is not good even if it is thinner, it needs to strengthen the auxiliary structure;

(2) The use of AAC panel as the inner partition wall greatly increases the usable area (about 8%); the use of AAC panel as the wall panel is very light (half the weight of the block), so the amount of foundation, beams, columns and steel bars It is much smaller; the conventional design of using aerated blocks as the inner partition wall is 150/200mm thick, and the occupied area is doubled compared with the use of AAC panel;

Different construction

(1) Slotting

Because there is a steel mesh in the slab, it is easy to slot both horizontally and vertically. In order to slot and open the holes, the plate can be hollowed out. The stability of the steel mesh is supported without affecting its stability; blocks with a thickness of 150 or more are simple Some, such as thin slotted walls/blocks are prone to penetration cracking, and the wall stability is poor; it is dangerous if the transverse slot is too long;

(2) Hanging heavy objects

Install heavy objects on the wall with a static load of 110-140KG and a dynamic load of 60-80KG; there is no problem with installing heavy objects such as air conditioners, water heaters, marbles, and tiles on the 75-120 thick slab wall; due to the poor stability of the blocks, the hanging Hanging heavy objects is very dangerous; especially the stability of 100-120 thick blocks is worse, and heavy objects cannot be hung;

Different Structure

(1) Different functions

AAC panel appears as a decorative material used for internal and external partition walls outside the main body of the building structure; aerated blocks exist as a structural part of the main body of the building;

(2) Different structure

The use of AAC panel as a wall panel does not require structural columns and reinforcement bands or ring beams, and doors and windows do not require lintels; it can be used independently without any auxiliary structure; aerated blocks are used as walls and the length exceeds 6 meters according to the architectural design regulations It is necessary to add structural columns to increase its stability, and the height of more than 4 meters needs to increase the concrete ring beam; the laying of two layers of aerated blocks requires reinforcement belts to increase the stability;

(3) Different construction

AAC panel does not require masonry mortar, as long as it is squeezed with bonded gypsum at the contact with the panel or column or beam, and the amount is small; aerated block requires a large amount of masonry mortar and is used to construct the column beam. , Reinforced belt connected to form a wall

Different decorations

Plastering or not: After the installation of the AAC panel, the wall has a high level of flatness and does not require double-sided plastering. The decorative interface process is simplified, and it is enough to directly paint the plaster (one time) and spray the paint; according to the comparison of related projects, it can be seen that the AAC panel is used compared to the use The aerated block can reduce the decoration cost by no less than 15%; after the aerated block is built, it needs to be plastered on both sides and laid with anti-cracking steel mesh before scraping the putty (twice) and spraying the paint;

The construction speed is different

(1) Installation

Because the AAC panel is a production plan based on the secondary design of the drawings, it is the finished product that can be directly assembled and spliced on-site that arrives at the construction site, and because each piece has an area of 3.6 square meters and is very light, workers install and construct The speed is very fast; because the aerated block is a standard general-purpose material, it is necessary to prepare masonry mortar, so compared with AAC panel, the installation speed is obviously much slower;

(2) Auxiliary structure

ALC slabs do not require structural columns, ring beams, and reinforcement belts, so the construction period is shortened; aerated blocks require structural housing and ring beams to assist in installation, so the construction speed is restricted;

(3) Different decoration

AAC panel does not require double-sided plastering and is dry construction, so the construction speed is greatly improved; aerated blocks need double-sided plastering and wet construction, so the construction speed is greatly affected.

Comprehensive evaluation: According to the comparison of actual projects, it is known that the use of AAC panel can shorten the construction period by one third compared with the use of aerated blocks.

Different Quality

• The use of AAC panel for internal and external wall panels, there are fewer hollows and cracks on the wall;
• the use of aerated blocks as the surface of the wallboard will definitely have hollows and cracks, which are well-known common problems of materials.
