Description
Technical field
The present invention relates to a kind of preparation methods of concrete prefabricated board.
Background technique
China is a big coal country, using coal as power generation substantially fuel.The energy industry stable development in China, power generation
Ability annual growth is 7.3%, and the rapid development of power industry brings sharply increasing for clinker and flyash discharge capacity, is fired
The clinker and flyash total amount that coal steam power plant is discharged every year increase year by year.Flyash is under catching in the flue gas after coal combustion
The fine ash come, main oxides group become：SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2 etc..Place is not added in a large amount of flyash
Reason will generate fugitive dust, pollute atmosphere；Silt up if being discharged into water system and will cause river, and toxic chemical substance therein can also be right
Human body and biology cause damages.
China is the per capita limited country of resource reserve again, the comprehensive utilization of flyash and clinker, change give up into
Treasured turns bane into boon, it has also become an important techno-economic policy in economic construction of China is to solve China's power generation environment
It pollutes, contradictory important means and one of the task of the faced solution of power generation between resource shortage.By exploitation, powder
Coal ash is widely used building each department such as work, building materials, water conservancy.
With economic construction, construction industry is phased out the use of common brick, and serious waste resource is understood in the production of common brick, and
The pollution that will cause environment, the characteristic without sustainable development.Therefore, construction industry starts largely to use concrete product,
It is mainly reflected in concrete prefabricated material, concrete prefabricated material has the following advantages that：One, modularized production, root may be implemented
According to needing to produce different products, is transported later to scene, installed at the scene；Two, the construction period of building is improved,
Different plate can be produced in advance according to construction requirements, it is time saving and energy saving to install at the scene；Three, with sustainable development
May, clinker and flyash belong to industrial waste, turn waste into wealth, circular economy.
But at present concrete prefabricated board manufacturing enterprise problem is encountered that, demoulding time is longer, and general demoulding time is
10~12 hours, a mould can only be gone out within one day, production efficiency is lower, and worker-hours are also very long.From preparation raw material, pour
It builds demoulding to the end to discharge, the entire duty cycle at least needs 13 hours, and not only labor intensity of workers is big, but also production efficiency
It is low.
Therefore, a kind of preparation method is simple, shortens demoulding time, reduces the system of the concrete prefabricated board of labor intensity of workers
Preparation Method is suggested.
