Low-clinker high-impermeability field floor hardening material based on dry process desulfurized fly ash

Abstract

The invention discloses a low-clinker high-impermeability field floor hardening material based on dry process desulfurized fly ash. The material comprises, by volume, 10-40 parts of blast furnace slag, 5-45 parts of converter steel slag, 0.1-40 parts of sandy soil, 5-20 parts of sintered desulfurized ash, 5-8 parts of slag powder, 1-2 parts of cement, 0.1-2 parts of an additive and 12-13 parts ofwater. Batching, stirring, paving, rolling and curing construction are carried out in sequence on the components, thus obtaining the low-clinker high-impermeability field floor hardening material. Theinvention adopts blast furnace slag, converter steel slag, sintered desulfurized ash and sandy soil as the main raw materials, and takes an appropriate amount of slag powder and a small amount of cement as the auxiliary materials, the obtained field floor hardening material has a strength grade up to C10-C25, and can replace low-strength grade concrete for application to floors of factories and mines, storage yards and construction sites and roadbases.

Description

technical field [0001] The invention relates to the field of building materials, in particular to inorganic non-metallic materials, in particular to a field hardening material with less clinker and high impermeability based on dry desulfurization ash. Background technique [0002] With the increase of environmental protection, it is required to increase the disposal of all kinds of muck to reduce land occupation and environmental pollution. The waste slag discharged in some remote areas that has not been treated for many years has agglomerated, such as the blast furnace slag and steel slag piled up in Xinjiang, which is difficult to use according to conventional methods. At the same time, the tailings of mining enterprises and the muck produced by various projects need to be utilized urgently. For example, the shield sludge generated by the shield construction method contains gravel and soil, which is generally used for earthwork backfill, and the resource utilization rate i...

AI Technical Summary

Problems solved by technology

[0005] The comprehensive utilization rate of these construction and industrial solid wastes is low, and they are piled up in large quantities, which has a great impact on the environment

In addition, due to the shortage of cement and sand and gravel supply, the cost of commercial concrete has risen, and the production cost of low-grade (<C30) concrete is not much different from that of C30.
