Description

A kind of " acid bubble partition method " suitable for the decryption of ancient tabia formula
Technical field
The present invention relates to the archaeological research field of traditional tabia material, and in particular to one kind is applied to ancient tabia formula " the acid bubble partition method " of decryption.
Background technology
It is well known that tabia is a kind of traditional building material formed by three kinds of lime, soil, sand material matchings, extensively Apply to the important places such as urban construction, military affairs, water conservancy, grave and local-style dwelling houses.
Traditional tabia category air hardening cementitious materials, it is necessary to which maintenance could solidify in atmosphere.Lime in raw material plays glue Knot acts on, typically by white lime（Ca(OH)2）Or quick lime（CaO）Introduce, lime and the CO in air2Step-reaction generates carbon Sour calcium and make material consolidate.As long as can with air contact and curing time long enough, lime in dispensing it is final it is inevitable all Can be with the CO in air2Step-reaction generates calcium carbonate（CaCO3）, chemically react extremely simple：
CaO + H2O → Ca(OH)2+∆Q
Ca(OH)2 + CO2 = CaCO3 + H2O。
That is, the principle of solidification of tabia is very simple, its solidification process is purely exactly the formation of calcium carbonate Journey.In the solidification process of tabia in addition to the carbon dioxide in lime and air produces chemical reaction, in tabia Other chemical reactions will not occur between three kinds of lime, soil, sand raw materials, chemical change will not also occur for soil and sand itself.Finally Result is that calcium carbonate, the mixture of sand and soil are formd after soil is got up with sand by calcarinate（It is commonly called as tabia）, native and sand Simply relatively evenly it is dispersed among formed tabia block.If soil therefrom can intactly be isolated with sand Come, so that it may realize that ancient tabia raw material is traced to the source with what is be formulated.But high-quality ancient tabia is extremely hard, according to simple broken Broken means do not simply fail to come out in soil and sand separation, or even the sand grains in sample can be broken into pieces.How this problem is solved.Through Exploration and experiment repeatedly is crossed, tabia " acid bubble partition method " proposed by the present invention can dexterously solve this problem.
The content of the invention
It is an object of the invention to provide a kind of " acid bubble partition method " suitable for the decryption of ancient tabia formula.Invention profit It is a kind of science that formula can be carried out under the premise of raw material character is not destroyed and is traced to the source with raw material with the principle of solidification of tabia material Research meanses.
Acid bubble partition method principle：Calcium carbonate category alkaline matter, carbon dioxide will be discharged at once after meeting strong acid, and progressively Disintegrate.For ancient tabia, after the calcium carbonate constituents " acidolysis " of cementation are wherein played, so that it may by three originally hard conjunctions Soil block scatter, as long as the concentration and quantity of acid are enough, so that it may easily separate sand and soil.
A kind of " acid bubble partition method " suitable for the decryption of ancient tabia formula, comprise the following steps：
1）First bulk sample is meshed and baked roughly, weighs up M（About 500g) a gram sample is put into acid-resistant container；
2）Pour into excessive watery hydrochloric acid, be slightly agitated for, calcium carbonate is all decomposed, the addition of hydrochloric acid with bubble in sample completely without, Untill sample all spreads out；
3）Calcium removes：Repeatedly plus water, rinsing, precipitation remove supernatant liquor, until upper solution in neutrality；
4）Soil separation：Clay is stired and make muddy and repeatedly rinsed, upper strata turbid solution is all moved into another container to be separated with sand；Will The clay that turbid solution obtains after precipitating again takes out, dries, weighed, you can obtains the quantity of soil, is designated as MSoil；
5）Sand obtains：By step 4）Sand precipitation after take out, drying, you can obtain the total quantity of sand in sample, be designated as MSand；
6）Sand is classified：The mesh of aperture 5,8 mesh, 10 mesh, 20 mesh, 40 mesh, 60 mesh, 7 standard screens of 100 mesh are chosen, by step 5）'s Sand is sieved, and further analyzes the fineness of sand（Grain composition）；
7）Calcium is calculated：CaCO in sample can finally be calculated3Quantity：M CaCO3=M-MSoil-MSand；
8）Calcium converts：Step 7）Calcium carbonate quantity in the sample calculated, can be conversed according to chemical formula in dispensing white lime or The quantity M Ca (OH) of quick lime2、MCaO；
9）Charge ratio：Obtain MCa (OH)2、MSoilWith MSand, so that it may converse lime:Sand:The ratio of soil.

Compared with prior art, the present invention has following beneficial effect：
The present invention makes full use of traditional tabia not acid-resistant property, then by modes such as metering, acid bubble, separation, screening, conversions, The formula of ancient tabia and tracing to the source for raw material can be achieved, this method is easy to learn, is that one kind can be before raw material character not be destroyed Put the scientific research means that formula is traced to the source with raw material that carry out.
