Project abstract:

Assessment of the current state of the problem being solved is a scientific and technical problem: the recycling of coal combustion waste remains an unresolved environmental and economic problem that can be successfully solved through the use of ash and slag in the production of building products, and in particular cellular concrete. Cellular concretes are particularly light concretes used in construction mainly in the form of blocks for masonry walls. Due to their porous structure, cellular concrete blocks are heat-, sound–insulating, lightweight, and have many advantages over traditional brick wall products, which are the most widely used in monolithic and private construction.

Description of the problem that the project is aimed at solving:

Development of formulations and modeling of technology for the production of aerated concrete blocks using ash and slag waste that meet the requirements of regulatory documentation for construction in seismic areas, followed by their certification for compliance with GOST 21520 requirements.

Novelty:

Selection of the formulation and modeling of the technology for the production of aerated concrete blocks based on ash and slag waste from the boiler house of a thermal power plant, ensuring the ratio of density and strength necessary for use in earthquake-prone areas. This study is unique for this type of ash and slag boiler UK CHP has never been conducted in Kazakhstan, and therefore has no analogues.

The purpose of the project is to develop a formulation and modeling technology for the production of aerated concrete blocks using ash and slag waste that meet the requirements of regulatory documentation for construction in seismic areas, followed by their certification for compliance with GOST 21520 requirements.
