Abstract
The invention relates to an Agatu modification method comprising the following steps of: a. crushing Agatu in a crusher; b. roasting at 1000 DEG C for 3 hours in a high-temperature roasting furnace; and c. milling the Agatu in a ball mill after the Agatu is naturally cooled to the temperature room, and then sieving by using a sieve with 180 meshes for later use. The porosity of the modified Agatu reaches 43 percent, and the average compression strength thereof is not lower than 9.12MPa; the Agatu is in a good condition basically after being soaked for 30 days. The invention solves the problems that when the Agatu is used as a roof (top surface) building material, the Agatu has low strength and poor weather fastness, is easy to generate crack and leaks rainwater, and time and labor are wasted when the Agatu is shaken.
Description
Technical field
The present invention relates to a kind of method of modifying of material of construction.It exactly is a kind of Ah loud, high-pitched sound's land reform property method.
Background technology
Ah loud, high-pitched sound's soil is that Tibet abounds with a kind ofly contains about 10%SiO
2Ls.The compatriot of Tibetan does the traditional building material of monastic building ground and room (top) face with it.During use, the fragment that Ah loud, high-pitched sound's soil is broken for size fractionated is done aggregate, does gelling material preparation pulping with an amount of red clay of powdered Ah loud, high-pitched sound soil admixture, rams to build with a kind of special pestle stone then to form.After treating the complete calculus of slurries, polish flat with sandstone earlier, on sheepskin, dip in butter scouring polishing repeatedly then, the compatriot of this build process Tibetan claims " Da Aga ".There is more than 1,000 monastery of size in Tibet, has the precious Tibetan's cultural heritage of large quantities of China, like famous world cultural heritage Potala Palace, Luobulin Fortress, Sakya Monastery etc.Over the past thousands of years, Tibet is continued to use this traditional material and build process method always and is built monastic building ground and room (top) face, and the protection reparation of historical relics such as ancient building, mural painting.Because this material of construction is that Ah loud, high-pitched sound's soil fritter of size fractionated is done aggregate, powdery Ah loud, high-pitched sound soil and red clay are made gelling material, and its intensity is very low; Weathering resistance is also very poor; When doing room (top) face material of construction especially, the calculus body just produces be full of cracks after 3～5 years, because of the no gelling material loose seepage rainwater that becomes; Cause palace roof leakage rainwater, wood is made up the mural painting of building with exquisite do great damage.Therefore, the modification of Ah loud, high-pitched sound's soil has very important meaning to the maintenance and the mural painting protection of Tibet ancient architecture.
Summary of the invention
In view of above-mentioned, the object of the invention aims to provide a kind of Ah loud, high-pitched sound's land reform property method.
The objective of the invention is to realize like this:
A kind of Ah loud, high-pitched sound's land reform property method the steps include:
A. Ah loud, high-pitched sound's soil is pulverized in kibbler, grain size screening is the particle Ah loud, high-pitched sound soil of 5mm～6mm and 2mm～3mm respectively;
B. get Ah loud, high-pitched sound's soil that above-mentioned part pulverizes at 1000 ℃～1400 ℃ roasting kiln roastings 3～4 hours, back naturally cooling;
C. with the Ah loud, high-pitched sound after roasting soil particle in grinding in ball grinder, cross behind 180 mesh sieves subsequent use.
The beneficial effect of characteristics of the present invention and generation is:
1, analytical proof: through generating about 40% CaO, β-CaSiO of about 38% in Ah loud, high-pitched sound's soil of roasting of the present invention

3Adhesive bond.
Its reaction formula is following:
(1) Ah loud, high-pitched sound's soil roasting:
