Problems solved by technology

However, the reduction of water consumption means that the density of the material increases. If a low-density lightweight aggregate concrete slab is to be obtained, it must be achieved by adding a large amount of light aggregate, which is not good for environmental protection and economy.

Abstract

The invention discloses a light aggregate concrete plate with a flat and smooth surface and a preparation method thereof, the light aggregate concrete plate comprises a plate main body and a magneticlight aggregate, the magnetic light aggregate is distributed at the bottom of the plate main body, and the top surface of the plate main body is flat and smooth, wherein the magnetic light aggregate is prepared by adsorbing nano ferroferric oxide in particles of initial light aggregate, and the lightweight aggregate concrete plate is prepared from the following raw materials in percentage by mass:30 to 50% of cement, 10 to 20% of quartz powder, 0.05 to 0.15% of a water reducing agent, 0.05 to 0.15% of a first adhesive, 20 to 40% of water and 10 to 25% of the magnetic lightweight aggregate. According to the lightweight aggregate concrete plate with the flat and smooth surface, the magnetic lightweight aggregate is distributed at the bottom of the plate main body through the vibration effect and the magnetic force effect of the magnetic vibration table, so that the phenomenon that the lightweight aggregate floats upwards can be avoided without reducing the water amount and increasing the initial use amount of the lightweight aggregate, and the top surface of the lightweight aggregate concrete plate with the flat and smooth surface is flat and smooth; and subsequent plate surface decoration treatment is facilitated.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a light aggregate concrete plate with a smooth surface and a preparation method thereof. Background technique [0002] Lightweight aggregate concrete slabs have excellent properties such as low density, less material consumed per unit volume during preparation, sound insulation and heat insulation, and are widely used in buildings. However, during the preparation process, due to the large difference in density between the light aggregate and other materials, if the state of the slurry is not properly controlled, it is easy to cause the light aggregate to float, resulting in uneven surface of the light aggregate concrete slab, insufficient Beautiful, this is one of the important factors that current light aggregate concrete slabs cannot be used for decorative slabs. [0003] Usually, to prevent the light aggregate in the light aggregate concrete slab from floating during the for...
