The Study on Green High-performance Compound Concrete Mixed with Spontaneous Combustion Gangue and Slag;

The result shows that spontaneous combustion gangue and slag inter-promote in the course of hydration,early strength of pure slag system can be increased while its late strength not reduced by adding spontaneous combustion gangue less than 50%,the strength of binding material improves with increasing amount of slak.

Using the spontaneous combustion gangue and slag as mixing material of high-performance concrete,an orthogonal experiment with different match rations of concrete was conducted.

The ettringite formation of active Al_2O_3 in the spontaneous combustion coal gangue cementitious material is analyzed by XRD.

A systematical tests on chemical constituents,durability and harmful substances content,physical and mechanical properties of the spontaneous combustion coal gangue generated from Gaode,Fuxin City of Liaoning Province were made.

Crushing the gangue to the lightweight coarse aggregate, this paper designs 10 groups of specimen of polypropylene fiber spontaneous combustion coal gangue of lightweight aggregate concrete, using "uniform.

Take the boron sludge ceramisite of industrial waste residue as the coarse aggregate and both the river sand and Si-Mn Alloy Slag as the fine aggregate ,use the powdered self-ignition coal gangue as the active mixing material, mix some cement and polyacrylonitrile fibre, finally produce a kind of building wall slab which accords with the standard and has good performance.

Harm of spontaneous combustion gangue dump explosion and its counter techniques;
