Super-light sludge ceramic granules and preparing method

Abstract

The invention relates to a pottery particle and the preparing method thereof. An ultralight silt pottery particle is characterized in that it is made from silt and coke, and its raw materials comprise: silt 60-98m%, coke 2-40m%, flyash 0-25m% and bauxite 0-25m%, where the sum is 100%. And its preparing method comprises preprocessing raw materials, selecting raw materials, moulding, drying, presintering, baking and obtaining finished product. And it has large numbers of cellular pores, higher intensity, and small water absorption. And the method can turn silt into resource and solves secondary pollution problem.

Description

technical field

[0001] The invention belongs to building materials, and in particular relates to ceramsite and a preparation method thereof. Background technique

[0002] Because of its outstanding advantages and characteristics such as porous internal structure and light weight, ceramsite has broad application prospects in modern high-rise buildings and long-span structures. The current ceramsite mostly uses clay, shale and fly ash as raw materials and is sintered at high temperature. Since clay is a high-quality resource with a wide geographical distribution, the vigorous development of clay ceramsite will inevitably lead to the destruction and loss of a large number of high-quality cultivated land; coupled with the implementation of policies and regulations such as the reform of national wall materials, clay ceramsite will definitely withdraw from the field of building materials. Shale is a natural resource, and its geographical distribution is uneven. The composition an...
