Abstract

The invention relates to a non-burning self-cleaning permeable brick made of nickel-iron slag and a preparation method thereof. The permeable brick includes a base material and a fabric; wherein, the raw material components of the base material include by weight: nickel-iron slag 75 ‑90 parts by weight, 25‑40 parts by weight of cement, 0.3‑0.5 parts by weight of cement, 1‑3 parts by weight of water, 0.1‑0.3 parts by weight of concrete coagulant and 0.2‑0.4 parts by weight of anti-welding agent; the raw material components of the fabric In parts by weight, it comprises: 75-90 parts by weight of ferronickel slag, 30-40 parts by weight of iron oxide and 10-30 parts by weight of water. The invention uses ferronickel slag as a raw material, rationally utilizes waste resources, solves the problems of long-term stacking of ferronickel slag, occupies land resources, and pollutes the environment, saves resources and reduces costs, and the prepared new permeable brick has high efficiency, high energy, and high strength. , high compression, high wear resistance, not easy to break and high yield and so on.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a non-burning self-cleaning permeable brick made of ferronickel slag and a preparation method thereof. Background technique [0002] Ferronickel slag is the waste of nickel alloy extracted from loess nickel ore. It is formed by rapidly cooling molten blast furnace slag in water, and has potential hydraulic gelling properties. A large amount of ferronickel slag is piled up disorderly for a long time, and harmful substances will seep into the groundwater, thereby causing serious pollution to urban sanitation and living environment. Permeable bricks have been regarded as one of the important basic materials for sponge city construction because of their high strength and good water permeability. Especially since my country launched the sponge city construction plan in recent years, the number of sponge city pilot cities has continued to increase, and the demand for permeable brick...
