Problems solved by technology

In addition to keeping away from the source of electromagnetic radiation as far as possible, how to resist or weaken electromagnetic radiation, can we use building materials with the function of shielding and absorbing electromagnetic waves to protect the human body? In the current construction projects, the components of the existing ordinary plastering mortar are generally: ordinary Portland cement and limestone sand. This kind of mortar is not only heavy, but also does not match with light walls, and does not have the ability to shield and absorb electromagnetic waves. Function

Abstract

The invention discloses lightweight plastering mortar, which is characterized in that the mortar is formed by mixing the following components in part by weight: 20 to 25 parts of common silicate cement, 2 to 4 parts of slaked lime, 5 to 10 parts of light aggregate, 20 to 30 parts of electromagnetic wave absorption master batch, 30 to 50 parts of heavy aggregate and 1.0 part of composite auxiliaryagent, wherein the light aggregate is an inorganic vitrified hollow micropore material with fineness of less than 100 meshes, and the heavy aggregate is common river sand. The construction method comprises the following steps of: diluting the lightweight plastering mortar by adding water in an amount which is 30 to 50 percent of the weight of the mortar, mechanically or manually stirring the mortar till the mortar is mixed uniformly, and mechanically coating the mortar or manually constructing the mortar when the mortar reaches the viscosity suitable for mechanical coating or manual construction. The lightweight plastering mortar with function of shielding and absorbing electromagnetic wave can shield and absorb the outdoor electromagnetic wave, absorb the indoor electromagnetic wave and reduce the diffuse reflection of the indoor electromagnetic wave, is light and energy-saving, reduces the consumption of unit area material and has low unit area manufacturing cost; and when used for a lightweight wall, the lightweight plastering mortar can prevent hollowing, cracking and dropping, is favorable for mechanized construction, and has simple process.

Description

technical field [0001] The invention relates to a construction mortar, in particular to a lightweight plastering mortar and a construction method thereof. Background technique [0002] There is an electric field around any charged body, and the periodically changing electric field will produce a periodically changing magnetic field. The interaction between the electric field and the magnetic field produces electromagnetic waves. The phenomenon of electromagnetic waves launching or leaking into the air is called electromagnetic radiation. Excessive electromagnetic radiation causes electromagnetic pollution. At present, electromagnetic radiation pollution has become the fourth largest environmental pollution after water, air and noise. [0003] Generally speaking, radar systems, TV broadcasting transmission systems, radio frequency and microwave medical equipment, various electrical processing equipment, communication transmission stations, satellite earth communication statio...
