Abstract

The invention discloses a preparation method of light-weight non-burning ceramsite used in road infrastructure, which uses construction waste and industrial waste as main raw materials, and uses quicklime, desulfurized gypsum, Portland cement, ferrous sulfide and rice husk ash as main raw materials. The auxiliary components are sodium sulfate, loess, fluorite powder, sodium pyrophosphate, potassium lauryl ether phosphate, nano-alumina, and nano-zirconium silicate as additives; the preparation steps include material preparation, mixing, granulation and steam curing; The prepared light unfired ceramsite has an apparent density lower than 1.3g / cm3.

Description

technical field [0001] The invention belongs to a light-weight non-fired ceramsite used for road infrastructure and a preparation method thereof, and belongs to the field of road infrastructure. Background technique [0002] The demand for ceramsite in the process of road infrastructure is very large, especially in the process of road greening. Lightweight ceramsite can effectively improve soil water retention and promote the growth of plants under harsh conditions. At the same time, in the process of road infrastructure construction, construction waste and industrial waste are problems that need to be solved urgently in the process of environmental protection. Landfilling or incinerating construction waste and industrial waste will not only waste resources, but also pollute the environment. Contents of the invention [0003] The object of the present invention is to solve the above problems, and develop a light-weight non-fired ceramsite for road infrastructure and its p...
