ShandongSand-lime blockAutoclaved aerated concrete blocksWhen applied to the exterior walls of buildings, it does not require external wall insulation to meet the national energy-saving requirements. It is a new, environmentally friendly, and energy-saving green building material promoted by the country and is an upgraded product of the common aerated concrete blocks. Its main performance characteristics are:
（1Light bulk density：Autoclaved aerated concrete is not only used for partition walls and roof panels, but also more commonly for exterior walls. Its own weight is approximately one-third that of concrete.20Percent, bricks28％。
（2High耐火limit：Autoclaved aerated concrete fire resistance limit700℃Above all700℃The following material maintains its strength at high temperatures and is classified as a first-grade refractory material.
（3Insulation and heat preservation：Dry thermal conductivity of aerated concreteλ=0.12-0.16W/m·K, limited to concrete only13%, Solid brick masonry28.6%, is an insulating and heat-preserving structural material. Under the premise of ensuring the necessary thermal insulation performance, it can be much thinner than walls and roofs made of other materials.
（4Excellent durability：Autoclaved aerated concrete is a silicate material primarily composed of tobermorite, free from aging issues and resistant to weathering. It is a durable building material whose normal service life can perfectly match that of various types of buildings.
（5Green and eco-friendly：Autoclaved aerated concrete productsγ The radiation dose is merely12μγ/hWell below37μγ/h National standards of24μγ/hInternational Standards.
（6Good machinability：Easy to build with; one brick is equivalent to18A brick, reduces labor costs, and can be easily sawed, planed, cut, and grooved on-site for further processing.
（7Excellent sound insulation performance：The porous structure of aerated concrete endows it with excellent sound absorption and sound insulation properties.100mmThick砌block walls with double-faced plastering, average sound insulation rating of40.6dB。
（8Excellent seismic performance:
（9Fast construction speed, high installation efficiency.
（10Easily adaptable for secondary renovations.
ShandongB05Sand-lime blocks have soundproofing and noise reduction properties, making them popular in both residential and industrial buildings. They are convenient and quick for workers to use during construction and easy to process. Utilizing sand-lime blocks can effectively reduce construction costs (no need for double plastering, saving labor costs and simplifying processes; no need for additional insulation materials, increasing usable indoor space, and shortening the construction period).
