Gangue-containing fired brick and manufacturing method thereof

Abstract

The invention discloses a gangue-containing fired brick and a manufacturing method thereof. The fired brick comprises the following raw materials (by weight): 15-20 parts of fly ash, 15-20 parts of gangue, 2-5 parts of glass powder, 50-60 parts of shale, 2-5 parts of diatomite, 2-5 parts of titanium diboride, and 3-5 parts of magnesium oxide. The technology comprises the following steps: respectively crushing and screening shale and gangue as standby materials; fully stirring and mixing the standby materials and the other raw materials to obtain a mixture; adding water (water addition amount is 14-16% of total weight of the mixture) into the mixture and mixing and stirring, placing in a sealed container for 6-8 days after uniform stirring so as to obtain an aged material; carrying out secondary stirring and mixing on the aged material, extruding by the use of a vacuum extruder, and preparing a blank body through a slitter, a blank cutter and a blank turning machine; airing the blank ofa solid brick or cored brick until water content is 3-5%, and sintering in a brickkiln. The invention has the following advantages: resources cyclic utilization of fly ash and gangue can be achieved,and the finished product has good mechanical properties and mechanical properties.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a coal gangue-containing sintered brick and a manufacturing method thereof. Background technique [0002] my country is the largest developing country in the world. Urban and rural construction is inseparable from a large number of building materials. Although there are many unburned bricks and aerated bricks, the traditional building materials still occupy a large part of them. Usage amount. However, the current fired bricks are mostly simple shale bricks and clay bricks, and the firing process has many defects, resulting in many pores in the brick body, and poor strength and mechanical properties. Contents of the invention [0003] One of the objects of the present invention is to provide a sintered brick containing coal gangue with good mechanical properties and high strength. [0004] The technical solution is to include the following raw materials in parts by w...
