Problems solved by technology

Although the ceramsite fly ash has a high content and no clay component, the fly ash has poor viscosity and plasticity, and a large amount of water glass and gel resin must be added. Process control is difficult, easy to produce agglomeration and ring formation, and the production cost is still high

Abstract

This invention discloses biosolid-sludge mixed ceram site, belonging to the technical field of light materials. The biosolid-sludge mixed ceram site is prepared using raw materials as follows: biosolid of 10-30 parts by weight, and sludge of 70-90 parts by weight, wherein the biosolid is dehydrated mud and the sludge is river sludge and / or piling sludge. Accordingly, the mixed ceram site makes effective use of urban mud, and changes industrial waste solid into valuable; further, this utility model is wide in raw material source and is relatively low in cost.

Description

technical field [0001] The invention relates to a kind of ceramsite, in particular to a kind of ceramsite mixed with biological sludge and silt. It belongs to the technical field of lightweight materials. Background technique [0002] Ceramsite has excellent properties, such as low density, high cylinder compressive strength, high porosity, high softening coefficient, good frost resistance, and excellent alkali-aggregate reactivity. Especially because of its low density, internal porosity, uniform shape and composition, and certain strength and firmness, ceramsite has multifunctional characteristics such as light weight, corrosion resistance, frost resistance, earthquake resistance and good insulation. Utilizing these excellent properties of ceramsite, it can be widely used in building materials, horticulture, food and beverage, refractory and thermal insulation materials, chemical industry, petroleum and other departments. The application fields are becoming wider and wide...
