Abstract
The granular building material is made from natural or artificial pozzolans and not more than 5% by weight of lime (calculated as calcium oxide), the granules being internally consolidated by means of pozzolan consolidation, including mechanical consolidation formed by ettringite crystals and amorphous calcium silicate, calcium aluminate or calcium alumino-silicate or a mixture of any two or more calcium salts, the pozzolans preferably being fly ash.
Description
The present invention relates to material of construction, the material of construction of granular form particularly, for example: the particulate form, in particular for producing the aggregate of light construction module.
The invention provides a kind of granular form or particle material of construction (hereinafter referred to as particle).This material is to be made by the lime of natural or artificial volcanic ash and weight no more than 5% (calculating with calcium oxide).Pellet reaches inner glued by the glued form of volcanic ash.Comprise by crystal and the amorphous bodily form Calucium Silicate powder calcium aluminate or Calucium Silicate powder, or the mechanics gluing that forms of the mixture of any two kinds even more kinds of calcium salts.
Although we can use other natural or artificial volcanic ash, the volcanic ash in the material of construction of the present invention is preferably selected flyash for use.
Material of the present invention can be mixed with the lime of no more than 5% weight (calculating with calcium oxide) by volcanic ash, with calcium hydroxide for well; With mixture forming is granular and in 35 ℃～80 ℃, is better than 50 ℃～80 ℃ most particle is solidified.
Use the mixture of flyash and 3% calcium hydroxide (calculating 2.25% with calcium oxide), in 50 ℃, two hours short period of time, can reach glued, gained particulate shatter strength can up to 10 newton/centimetre
2The particulate shatter strength also can continue to improve within six months.Record was once arranged, after six months, the particulate shatter strength can up to 500 newton/centimetre
2
At 50 ℃, through six～ten hours curing, can be made into shatter strength be about 50 newton/centimetre
2Particle.
It is amazing obtaining big like this intensity in the short like this time, particularly under the extremely low situation of lime mixed volume.It has been generally acknowledged that the mixture of flyash and lime will reach the volcanic ash gluing, the used in amounts of lime is above 5% and need long set time.In general, before forming the strong rubber knot, need several days time at least.
With arbitrary specified prilling process, all can make the particle that size range is generally 5～15mm.Such as, with tablets press for example rotary drum or non-Spheroidgranulator produce, perhaps by making solid become the particulate process, perhaps extruding is perhaps with the roller compacting mixture material of fluting and the band of formation is cut into the length of requirement.
Accompanying drawing has been represented to be solidified and gained particulate shatter strength and the relation of set time behind 9 centimetres of rotary drums choosing grains through 50 ℃ by the mixture of 97% flyash and 3% lime.
Glued character is measured by X-ray diffraction and my fluorescence chemical analysis in the particle.
