Description
Technical field
The present invention relates to a kind of preparation method of concrete prefabricated board.
Background technology
Shi Ge big coal countries of China, with coal as power generation substantially fuel.The energy industry stable development of China, generates electricity
Ability annual rate of growth is 7.3%, and power industry is developed rapidly, brings sharply increasing for slag and flyash discharge capacity, is fired
The slag and flyash total amount that coal steam power plant is discharged every year increases year by year.Flyash is to receive to catch down in flue gas from after coal combustion
The fine ash come, main oxides are consisted of：SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2 etc..Substantial amounts of flyash is not added with place
Reason, will produce airborne dust, atmosphere pollution；If entering water system river can be caused to silt up, and toxic chemical substance therein can also be right
Human body and biology work the mischief.
China is again the limited country of a per capita resource reserve, the comprehensive utilization of flyash and slag, change give up into
It is precious, turn bane into boon, it has also become an important techno-economic policy in China's economic construction, is to solve China's power generation environment
Pollution, the important means of contradiction between resource shortage is also that power generation faces one of task of solution.Through exploitation, powder
Coal ash is widely used building all departments such as work, building materials, water conservancy.
With economic construction, building industry is phased out the use of Rhizoma Begoniae Willsonii, and serious waste resource is understood in the production of Rhizoma Begoniae Willsonii, and
The pollution of environment can be caused, not the characteristic with sustainable development.Therefore, building industry starts to use concrete product in a large number, its
Concrete prefabricated material is mainly reflected in, concrete prefabricated material has advantages below：First, modularized production, root can be realized
According to needing to produce different products, transport afterwards is installed at the scene to scene；2nd, the construction period of building is improved,
Different sheet materials can be in advance produced according to construction requirements, install time saving and energy saving at the scene；3rd, with sustainable development
Possibility, slag and flyash belong to industrial waste, turn waste into wealth, recycling 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 relatively low, and worker-hours are also very long.From preparation raw material, pour
Last demoulding discharging is built, the whole working cycle at least needs 13 hours, and not only labor strength is big, and 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 strength
Preparation Method is suggested.
