Abstract

A small load-bearing hollow building block is made up of cement, cinder, powdered coal ash, sand and additive through simple technology. It features high strength and load-bearing power (MU 7.5), good temp and voice insulating, light weight, low cost and easy construction of building.

Description

The prescription and the processing method of fly ash concrete load-bearing hollow small block
The invention belongs to the prescription and the processing method of a kind of fly ash concrete load-bearing hollow small block of material of construction.
At present, a large amount of cobbles or cement are mostly mixed in the building block of domestic production in aggregate, and density rating increases, and heat-insulating property descends.Intensity is lower, freeze thawing, carbonization, technical indicator such as softening are also lower and unstable.The production cost height is difficult to and the common brick competition.
The object of the present invention is to provide a kind of prescription and processing method of fly ash concrete load-bearing hollow small block.It has solved that existing block strength is low, production cost is high, freeze thawing, carbonization, technical indicator such as softening do not reach and require and problem such as instability.
Prescription composition that the prescription of fly ash concrete load-bearing hollow small block of the present invention and the purpose of processing method are achieved in that it is by cement: 14-16%, cinder: 68-70%, and flyash: 9-11%, sand: 3%, admixture: 2 ‰.(early strength water-reducing agent) formed.Its processing method: with cinder ageing, raw material sorting, clear assorted, fragmentation, storage, be warmed up to 10 ℃ more than-20 ℃, raw material mixing stirring, add water (water ratio is no more than 10%-12%), moulding, steam-cured 2-3 hour, intensification, intensification are no more than 40 ℃-50 ℃, stop to heat up, and then secondary temperature elevation, get final product.
The fly ash concrete load-bearing hollow small block intensity height that goes out with this prescription and explained hereafter, it is useless that load-bearing can reach MU7.5, body is light, good, the energy-conservation profit of sound is melted in insulation, this product 370MM-390MM body of wall can replace 500MM with interior any exterior wall, the 240MM interior wall can replace the interior wall of 370MM, can make and reduce approximately 1/5 with volume building masonry wall material usage, alleviate the basis carrying, make pile foundation can save the quantities of 15-20%, alleviate the load of various structure beam columns, reduced the cost of buildings.
Be the prescription and the processing method of fly ash concrete load-bearing hollow small block of the present invention below, its prescription composition by: cement 14-16%, cinder: 68-70%, flyash: 9-11%, sand: admixture 3%: 2 ‰ (early strength water-reducing agents) are formed.Its processing method: with the cinder ageing, the raw material sorting, clear assorted, broken (diameter is less than 10MM-15MM) is input to the raw material bin, is warmed up to 10 ℃ more than-20 ℃, water-containing rate with raw material mixing stirring, adds water (water ratio is no more than 10%-15%) less than 5%-7%, moulding is gone into its sign indicating number the steam-cured 2-3 in steam-cured chamber hour, begins to heat up, intensification is no more than 40 ℃-50 ℃, stop to heat up, and then carry out secondary temperature elevation, can go out product.

Claims (2)

1, the invention belongs to the prescription and the processing method of a kind of fly ash concrete load-bearing hollow small block of material of construction, the prescription composition that it is characterized in that it is by cement: 14-16%, cinder: 68-70%, flyash: 9-11%, sand: 3%, admixture: 2 ‰ form.
2, prescription and the processing method according to the described fly ash concrete load-bearing of claim (1) hollow small block is characterized in that: its processing method is earlier cinder ageing, raw material sorting, clear assorted, fragmentation, storage, intensification, raw material to be mixed stirring, add water, steam-cured, heat up, stop temperature, heat up again, get final product.
