Abstract

The invention provides a new energy-saving tignum. The raw material of the tignum comprises molten slag and an auxiliary raw material. The tignum is characterized in that: according to the gross weight of the raw material, the dosage of the molten slag is 70-90%, and the rest is the auxiliary raw material which comprises a framework formation agent, a fluxing agent and a clarifier and does not contains any poisonous and hazardous substance. The new type energy-saving tignum which is made from the industrial molten slag under sensible heat has the following advantages: evident energy-saving effect, much lower energy consumption during the courses of production and usage than that of common tignum, not occupying any arable land, not increasing new pollutant source, preferable business economic benefit and social benefit. The invention also discloses a method for preparing the new energy-saving tignum, which comprises the step of blending the molten slag and the auxiliary raw material.

Description

technical field [0001] The invention relates to the field of building materials. Specifically, the present invention relates to a method for directly producing energy-saving building materials using liquid slag and energy-saving building materials obtained by the method. Background technique [0002] Since the reform and opening up, my country has paid more attention to the utilization of industrial waste, especially in the past ten years, the utilization of industrial waste has achieved gratifying results, and the utilization rate of industrial waste has continued to rise. Conventionally, industrial furnace waste slag has the following uses: solid dry (block) slag is mainly used as raw material for building roads, railways, foundation projects, smelting mineral wool or as concrete aggregate, and water-quenched slag is widely used as cement mixture (filler) ), and a small amount of slag is converted into expanded beads for use as lightweight aggregate for building materials...
