Abstract
A high-strength powdered coal ash brick is made up of powdered coal ash and cement with volume ratio of (70-90) to (10-30) through adding water, stirring, stamp shaping, and curing for 28 days or more, and features high strength and resistance against weathering and corrosion, long service life, low cost and no environmental pollution.
Description
The present invention relates to the production technology of fine coal brick.
China is the country based on thermal power generation, at present, about 6000 ten thousand steres of annual discharging flyash, pile up like a mountain as waste residue for a large amount of flyash, land occupation, contaminated environment, causes public hazards.Utilize flyash to manufacture brick, turning waste into wealth has suitable large economy to be worth.
The general wall body building material of China is to use common brick at present, and the demand of common brick increases day by day, produces common brick and needs a large amount of clays, and a large amount of clay-brickmakings will cause effective cultivated area to reduce, and national economic development is caused damage.Utilize brick making from fly-ash to replace common brick to become when previous important problem.CN1133271 discloses a kind of brick making from fly-ash technology, it is to be primary raw material with flyash and ordinary cement, adds certain quantity of additive, and aqueous solution pressurization forms, and add steam curing and make flyash brick, the every index of the flyash brick that adopts this method to make meets or exceeds the standard of country.Its weak point is, its complex manufacturing, and the brick making cost height, energy consumption is big.
Purpose of the present invention just provides a kind of production technology of high-strength fly-ash brickmaking, and its production method is simple, and is easy to operate, and the flyash brick cost of producing in this way is low, intensity is high.
A kind of production technology of high-strength fly-ash brick, it is characterized in that: with flyash and cement by volume flyash: cement=70-90: 10-30 add water and mix and mix thoroughly, send into impact molding machine then and strike out adobe, press normal concrete maintenance process maintenance at normal temperatures more than 28 days, finished product.The stamping press of impact molding machine must not be less than 10MPa.
The high-strength fly-ash brick that the present invention produced than ordinary red brick intensity height, weather resistance, anticorrosive, long service life, can be used for the building bearing body of wall.It is simple to compare production technology with the production technology of using additive powder process coal-dust brick, does not need steam curing, energy savings, cost saving, reduction brick making cost, the whole process of production environmentally safe.
Accompanying drawing is technological process of production figure of the present invention.
Embodiment:
With flyash and cement by volume flyash: cement=70-90: 10-30 add water and mix and mix thoroughly, send into impact molding machine then and strike out adobe, the stamping press of impact molding machine must not be less than 10MPa.Press normal concrete maintenance process maintenance then at normal temperatures more than 28 days, finished product.
