Abstract

The invention provides artificial unfired solid core ceramsite, ceramsite concrete and a preparation method of the ceramsite concrete. The artificial unfired solid-core ceramsite is prepared from foundry industry waste ash, cement, glass fibers, water and other materials, can replace small stone aggregate in concrete to be applied to the concrete, does not affect the strength of the concrete, and can also improve the strength of the concrete to a certain extent.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an artificial fire-free solid core ceramsite, ceramsite concrete and a preparation method thereof. Background technique [0002] Concrete is currently the most widely used building material, specifically an engineering system material in which aggregates are cemented into a whole by cementitious materials. Due to the advantages of easy preparation, simple construction, low cost and wide application, concrete materials are widely used in roads, bridges and various buildings. [0003] Traditional concrete is mainly prepared by stirring and mixing cement, powder, coarse aggregate, small stone aggregate, water and admixtures. Small stone aggregate is made by artificially crushing natural ore. The amount of concrete is relatively large, and the demand for small stone aggregates is relatively large. However, natural ore is a natural resource, which is strictly controlled,...
