Actually solid material, density is relatively large, at least in 800kg/m3More than, the light wall material quality made is relatively
Greatly, heat insulation effect does not include ideal.
Content of the invention
The defect existing for light wall material of the prior art, it is an object of the invention to be by mud
And construction waste material etc. by a kind of low cost of expanded acquisition, density is little, intensity is high, heat conductivity is low, corrosion resistance is strong
Sludge ceramsite.
Another object of the present invention is to be to provide that a kind of density obtaining based on modified haydite is little, intensity is high, heat-insulated
Heat-insulating property is excellent, shrinkage factor is little, water absorption rate is low, anti-permeability performance is strong, frost resistance is good, fire prevention and durability is excellent, sound insulating and absorbing effect
The haydite good, antidetonation shock attenuation is good strengthens foam concrete heat insulation building block.
A further object of the invention is to be that providing a kind of process is simple, low cost to prepare described haydite enhancing foam mixes
The method of solidifying soil heat insulation building block.
In order to realize the above-mentioned purpose of the present invention, the invention provides a kind of sludge ceramsite, this sludge ceramsite is by building rubbish
Expanded under 1100 DEG C～1300 DEG C high temperature after at least one in rubbish, flyash and stone powder and mud mixing granulation obtain.
Preferably sludge ceramsite by least one in building waste, flyash and stone powder and mud in mass ratio 20～
After the mixing granulation of 40:30～50, high temperature puffing obtains；Wherein, the water content of building waste, flyash and stone powder and mud all exists
Between 20wt%～45wt%.
Preferably sludge ceramsite particle diameter is 15～25mm.
Preferably sludge ceramsite density is 250～300kg/m3.
The mud that the present invention adopts can be domestic sewage sludge, industrial wastewater sludge or copper water-supply pipe according to source, this
The main component of a little mud is substantially the same and all meets the preparation of haydite of the present invention and require.
The preparation of the sludge ceramsite of the present invention has to control temperature conditionss, under suitable hot conditionss, on the one hand
Be conducive to quick volatilization and the expansion of moisture, carry out internal pore-creating, so that sludge ceramsite raw material is closed under the high temperature conditions
Hole, forms and closes microcellular structure, imparts haydite light weight, the feature that high-strength, heat conductivity is low.Under high temperature action, sludge ceramsite
Raw material Outside surface glass matter, leads to appearance hard, and under the surface tension effects of itself, carries out shrinking closed pore.Using this
The 40% of the haydite enhancing foam concrete heat insulation building block density only normal concrete stripping and slicing density that bright haydite is made～
50%；Heat conductivity is the 1/5～1/3 of normal concrete stripping and slicing.
The preparation of the sludge ceramsite of the present invention has to coordinate building waste, flyash and stone powder etc. to use in mud, dirty
Mud plays good cementation, effectively strengthens the intensity of sludge ceramsite, substantially reduces the density of sludge ceramsite simultaneously.
The sludge ceramsite that the present invention obtains has the more elliposoidal of standard or spherical or gravel, and color is brown or brown
Color.
The construction waste crushing of the present invention is to reuse in the range of 2～5mm to particle diameter.
The granularity of the flyash of the present invention and stone powder is all in the range of 70～90 mesh.
Preferably sludge ceramsite is prepared via a method which to obtain: by least in building waste, flyash and stone powder
Plant and mix with mud, after equilibrium moisture content to 30wt%～45wt%, by granulator granulation, pelletize gained particulate matter is placed in
In Expanded Clay Rotary Kilns, expanded at a temperature of 1100 DEG C～1300 DEG C, obtain final product.
The preparation of the sludge ceramsite of the present invention preferably controls the moisture of sludge ceramsite raw material in 30wt%～45wt%
Between, can effective conditioning of mud haydite pore structure, moisture under the high temperature conditions quickly volatilization, expand, make in sludge ceramsite

Table 1 haydite level joins table
The quick mortar bars method of table 2 tests the alkali result of haydite
Result calculates and processes
Length expansion rate is calculated as follows:
The expansion rate (%) when 14d age for the ξ --- --- test specimen, is accurate to 0.01%；lt--- --- test specimen is in 14d
Length (mm) during age；l0The first length (mm) of --- --- test specimen；The length (mm) of δ --- --- side head；
When the length expansion rate of single test specimen, average value difference meets following one of two things with 3 piece lengths expansion rates
Requirement when, take 3 piece lengths expansion rate volume arithmetic mean of instantaneous values as length expansion rate:
1st, when meansigma methodss are less than or equal to 0.05%, single piece lengths expansion rate is equal with the absolute value of the difference of meansigma methodss
Less than 0.01%；2nd, when meansigma methodss are more than 0.05%, single piece lengths expansion rate is respectively less than meansigma methodss with the difference of meansigma methodss
20%.When not meeting above-mentioned requirements, remove 3 piece lengths expansion rate minima, take remaining 2 piece lengths expansion rates
Arithmetic mean of instantaneous value as length expansion rate.When 14d age length expansion rate is less than 0.10%, aggregate is assessed as non-
Alkali --- silica reaction active aggregates；Otherwise, aggregate is assessed as alkali --- silicate reaction active aggregates.Note: work as length expansion
When rate is more than or equal to 0.10% and is less than 0.20%, tb/t2922.3 may also be employed and test further, thus finally determining
The Plant ecology of aggregate.
