Abstract

The invention discloses a production method of a self-heat-preservation lightweight aggregate concrete hollow building block. The problem of comprehensive utilization of high-titanium blast furnace slag and the problem that an existing clay brick cannot preserve heat are solved. The method comprises the following steps that (1), all components in a dry mixed material are placed into a blender to be stirred and uniformly mixed after being metered in percentage by weight; (2), water and an addition agent are added, and the mixture is further stirred and uniformly mixed; (3), the obtained material is subjected to vibration, extrusion and forming through a brick making machine, and a semi-finished product is obtained; (4), the semi-finished product is demoulded and transferred to a storage yard for natural curing or sent to a steam curing device for steam curing; (5), the self-heat-preservation lightweight aggregate concrete hollow building block can be obtained after curing reaches the standard. The self-heat-preservation lightweight aggregate concrete hollow building block has the characteristics of being low in weight and good in heat preservation and sound insulation effects, the major problem of external wall heat preservation is solved, the problem of environmental protection treatment of the high-titanium blast furnace slag is solved, the natural environment is protected, and the self-heat-preservation lightweight aggregate concrete hollow building block belongs to a model of circular economy for environmental protection, energy conservation and emission reduction.

Description

technical field [0001] The invention relates to the field of production methods of building materials, in particular to a production method of self-insulating lightweight aggregate concrete hollow blocks. Background technique [0002] As the country vigorously develops prefabricated buildings, especially in the "13th Five-Year Plan" Prefabricated Building Action Plan issued by the Ministry of Housing and Urban-Rural Development, it has determined the goal of "the proportion of national prefabricated buildings accounting for more than 15% of new buildings in 2020", At the same time, the state requires all buildings to adopt prefabricated structures and the assembly rate should increase from the current 10% year by year to more than 30% in 2020. A new type of building wall material with a prefabricated hybrid structure formed by different combinations of different structures has gradually become the main component of today's wall building materials and an inevitable developmen...
