Abstract
The invention discloses a kind of radioprotective dry-mix, be made up of following weight raw material: ordinary Portland cement 10-30%; High-alumina cement 5-20%; Barite sand 30-60%; Barium sulfate 5-25%; Hollow steel ball 0-10%; Hollow alloy pearl 0-10%; Latex powder 0.1-3%; Ether of cellulose 0.1-1%.Use the dry-mix of above formula to add water and pour into a mould the body of wall of thick 30cm, after the maintenance of 28 days, use X-ray examination equipment, the radiation for 0.3msv is less than 0.001msv after body of wall.The present invention effectively can intercept or reduce X-ray, gamma ray, prevents the harm of the Radiation On Human body of radioactive element.Also have cheap, easy construction, easy handling, the advantage that mechanical wall intensity is high.
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 architectural stone of laying bricks cohere material, added water into by a certain proportion of sand and consolidating material (cement, lime putty, clay etc.), be also mortar, also make mortar.Mortar is added water by gelatinous material (cement, lime, clay) and fine aggregate (sand) to stir synthesis.Conventional has sand-cement slurry, mixed mortar (or being cement lime mortar), lime mortar and clay mortar.
Mortar in the market all only has mobility and the water-retentivity of architectural mortar, but as the place of some high radiation, the place such as radiology department as Nuclear power plants, hospital has very strong radiation, and the body of wall that ordinary mortar is built by laying bricks or stones cannot prevent ray to the radiation of human body.
Summary of the invention
The object of the invention is the defect for above-mentioned prior art, provide a kind of radioprotective dry-mix, its concrete structure made, overcome existing mortar making concrete structure and not there is radiation-resistant defect.
Object of the present invention can be achieved through the following technical solutions:
A kind of radioprotective dry-mix, it is characterized in that, it is made up of following weight raw material:
Radioprotective dry-mix according to claim 1, it is characterized in that described ordinary Portland cement is selected from label is 425,425R, 525,525R, the one in 625,625R.
It is one in CA50, A600, A700, A900 that described high-alumina cement is selected from label.
It is 5 orders that described barite sand is selected from granularity, 15 orders, the one in 30 orders.
Described barium sulfate is selected from process white, the one in nanoprecipitation barium sulfate.
The particle diameter of described hollow steel ball is selected from 1mm, the one in 2mm, 3mm.
The particle diameter of described hollow alloy pearl is selected from 1mm, the one in 2mm, 3mm.
Described latex powder is selected from redispersible latex powder, the one in polyether-modified W-Gum.
Described ether of cellulose is selected from Walocel MT 20.000PV, Natvosol, Vltra tears, the one 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.
