Method for manufacturing brick from waste ceramic

Abstract

The invention discloses a method for manufacturing a brick from waste ceramic, which comprises the following production steps of: (1) smashing the waste ceramic powder until the particle diameter is 3-12mm; (2) adding the waste ceramic particles and sand of which the particle diameter is 0.2-1.5mm into a stirrer at the mass ratio of 1: (0.2-0.5) to be stirred; (3) keeping the moisture in the stirrer to be 80%, adding cement which accounts for 0.05-0.1wt% of the waste ceramic particles into the stirrer, and vibrating and mixing under the microwave for 20-40 minutes; (4) taking the weight of the waste ceramic particles in the step (2) as a reference, mixing and stirring 0.25-1 part by weight of sand and stone mixture, 0.1-0.5 part by weight of cement, 0.03-0.1 part by weight of water and the waste ceramic particles for 10-30 minutes, wherein sand in the sand and stone mixture accounts for 10-40% of the total weight, and the particle diameter of the stone is 0.5-2cm; and (5) sending the stirred mixed material into a brick manufacturing machine to be shaped. The brick manufactured with the method has the advantages of good compactness and high intensity, and the product performance conforms to the relevant quality standard requirement.

Description

technical field [0001] The invention relates to building materials, in particular to a method for making bricks from waste ceramics. Background technique [0002] CN101748847A discloses an invention patent application for "a ceramic aggregate building block and its manufacturing method". The building block is made by mixing cement, aggregate and water, wherein the aggregate contains 1 to 100 % of ceramic aggregate; the production method is only to mix the components, press or stir according to the specifications. The above-mentioned patent application mainly uses waste ceramic products to make ceramic aggregate building blocks to achieve the purpose of recycling waste ceramics. The surface of the finished product has a smooth glaze layer. When using waste ceramics with a glaze layer to produce ceramic aggregate building blocks, the surface of the glaze layer is difficult to bond with other materials, so that the compactness and strength of the product cannot meet the requir...
