When we buy landscape tiles , we will find that landscape tiles are divided into sintered landscape tiles and non-sintered landscape tiles. Many people do not know their differences. In fact, non-sintered landscape bricks mean that the bricks made without firing are all non-sintered landscape bricks, such as carbonized bricks, non-fired and non-steamed bricks, and steam-cured (pressed) bricks. At present, steamed (pressed) bricks are widely used. Let's take a closer look at the use of this type of landscape brick.
Non-sintered landscape bricks are made of calcium-containing materials (lime, calcium carbide slag, etc.) and silicon-containing materials (sandy, coal ash, coal slag lime slag, slag, etc.), stirred with water, pressed and formed under natural conditions or artificially. Under the conditions of hydrothermal synthesis (steam curing or autoclaving), the reaction produces silicate construction products with hydrated calcium silicate and calcium hydrated aluminate as the main cement. The main varieties are lime sand brick, fly ash brick, slag brick and so on.
Many non-sintered landscape bricks have been used in construction projects, and their history can be traced back. The oldest non-sintered bricks in China are adobe, and some are still in use today. Modern non-sintered bricks began in 1906. In the 1920s and 1930s, concrete hollow blocks and aerated concrete blocks were introduced from abroad for partial construction in Shanghai and Beijing. The development of steam-cured fly ash bricks and autoclaved lime sand bricks began in the 50s and 60s. It has also developed slag bricks, autoclaved fly ash bricks, autoclaved slag bricks, autoclaved lime sand bricks, concrete bricks, cement-cured soil bricks, and carbonized bricks.
