The thermal conductivity level of the AAC Bricks keeps the room temperature warm during winter. The autoclaved aerated concrete block possessed the strong capability of absorbing water, so the volume water absorption rate increased quickly at first and then went down furiously, which could make the shrinkage of autoclaved aerated concrete block augment because of the decrease of its water absorption rate.

It is made from naturally raw material. Fire Resistant: Brick is the most commonly used building material for construction. AAC b locks are ideal for the entire building structure and Possess high structural integrity.

Through the mix ratio optimization test, the appropriate autoclaved aerated concrete block may be prepared for the production demand, whose technical indexes could satisfy the requirement of national specification. First results of finite element analysis were verified with experiment results of full-scale specimen. This material is comp aac block research paper inorganic and not combustible.

This facilitates their expansion in water, which can bring cracks in aac block research paper structure. A total of 20 prisms are tested in compression and 5 prisms are tested under bending.

Moreover, holding fire from spreading is a very good and positive thing in safety procedures. They cannot be damaged from smoke from pollution and smoke of the chimney in factories.

Furthermore, the reduction in dead weight by such a huge margin results in reduction of acc cement and steel usage for construction. This is bare minimum. Aac block research paper and SEM analysis indicate that, the higher the autoclaved aac block research paper is, the smaller the size of hydration products most of them are tobermorite and hydrogamet is, and the crystallinity has a little increase; with the extension of autoclaved time, the size of products is smaller, the crystallinity is first increased and then decreased, the crystal form of tobermorite turns 1.

Low Maintenance: In summer, it is cool and nice. Different types of shear connectors are used to evaluate their effect on failure loads. On the basis of the characteristics of AAC blocks and the dry masonry thin-bed mortar, a kind of high performance dry-mixed Mortar for dry masonry process of AAC blocks was developed. The experimental results show that equilibrium moisture content EMC is 6.

This a big plus that helps in building maintenance. Expansion agent which is used for this process is alu minum powder; this material reacts with calciu m hydro xide which is the product of reaction between cement and water.
