Abstract
The invention discloses radiation-resistant dry-mixed mortar which comprises the following raw materials by weight: 10-30% of ordinary portland cement; 5-20% of high alumina cement; 30-60% of barite sand; 5-25% of barium sulfate; 0-10% of hollow steel balls; 0-10% of hollow alloy balls; 0.1-3% of latex powder; and 0.1-1% of cellulose ether. After a wall with a thickness of 30 cm is poured by the dry-mixed mortar with the above formula and is maintained for 28 days, the wall is inspected by an X-ray apparatus, and radiation of 0.3 msv becomes less than 0.001 msv behind the wall. The dry-mixed mortar of the invention can effectively obstruct or reduce X ray and Y ray, can prevent damage to human body caused by radiation of radioactive elements, and also has the advantages of low price, convenient construction, easy operation, and high wall mechanical strength.
Description
Technical field
The invention belongs to building material field, be specifically related to a kind of radioprotective dry-mix and preparation method thereof.
Background technology
Mortar be the architectural stone of laying bricks use cohere material, by a certain proportion of sand and consolidating material (cement, lime putty, clay etc.) Jia Shui with become, be also mortar, also make mortar.Mortar is by gelatinous material (cement, lime, clay) and fine aggregate (sand), to add water to stir synthetic.Conventional have sand-cement slurry, mixed mortar (or being cement lime mortar), lime mortar and a clay mortar.
Mortar in the market all only has mobility and the water-retentivity of architectural mortar, but the place of some high radiation of picture, as the places such as radiology department of Nuclear power plants, hospital have very strong radiation, the body of wall that ordinary mortar is built by laying bricks or stones cannot prevent the radiation of ray to human body.
Summary of the invention
The object of the invention is the defect for above-mentioned prior art, a kind of radioprotective dry-mix is provided, the concrete structure of its making, overcomes existing mortar making concrete structure and does not have radiation-resistant defect.
Object of the present invention can be achieved through the following technical solutions:
A radioprotective dry-mix, is characterized in that, it is comprised of following weight part proportioning raw material:
Radioprotective dry-mix according to claim 1, is characterized in that it is 425,425R that described ordinary Portland cement is selected from label, 525,525R, a kind of in 625,625R.
It is CA50 that described high-alumina cement is selected from label, A600, A700, a kind of in A900.
It is 5 orders that described barite sand is selected from granularity, 15 orders, a kind of in 30 orders.
Described barium sulfate is selected from process white, a kind of in nanometer process white.
The particle diameter of described hollow steel ball is selected from 1mm, 2mm, a kind of in 3mm.
The particle diameter of described hollow alloy pearl is selected from 1mm, 2mm, a kind of in 3mm.
Described latex powder is selected from redispersible latex powder, a kind of in polyether-modified W-Gum.
Described ether of cellulose is selected from Walocel MT 20.000PV, Natvosol, Vltra tears, a kind of in carboxymethyl cellulose.
Described barium sulfate granularity is 325 orders.
The present invention adopts technique scheme, has the following advantages: effectively intercept or reduce X ray, gamma ray, preventing the harm of the Radiation On Human body of radioactive element.In addition, the present invention also has cheap, easy construction, easy handling, the advantage that mechanical wall intensity is high.
