Alkali-activated high-titanium content slag small-sized hollow block and preparation method thereof

Abstract

The invention discloses an alkali-activated high-titanium content slag small-sized hollow block and a preparation method thereof. The alkali-activated high-titanium content slag small-sized hollow block is characterized by consisting of the following raw material components through mixing: 100 parts by weight of water-quenched granulated blast furnace high-titanium slag superfine powder, 25-40 parts by weight of an alkali activator, 468-840 parts by weight of water-quenched granulated blast furnace high-titanium slag and 30-45 parts by weight of water. The preparation method comprises the following steps: uniformly mixing the raw materials by weight; conveying the mixed raw materials into a baking-free brick machine; performing vibration molding and mechanical automatic demolding to produce hollow block green bodies; stacking the hollow block green bodies; and humidifying and maintaining the stacked hollow block green bodies in a maintenance shed to obtain the alkali-activated high-titanium content slag small-sized hollow block. By adoption of the alkali-activated high-titanium content slag small-sized hollow block, all the solid raw materials come from lots of industrial solid waste high-titanium slag and are environmentally friendly; and the alkali-activated high-titanium content slag small-sized hollow block is low in apparent density, light in unit weight, easy to transportand construct, suitable for building public and residential building walls and high in practicability.

Description

technical field [0001] The invention belongs to the comprehensive utilization of industrial solid waste and building material hollow block and its preparation, and relates to a small hollow block excited by alkali with high titanium slag and its preparation method. The solid raw materials of the alkali-activated high-titanium slag small-sized hollow blocks of the present invention are all derived from bulk industrial solid waste high-titanium slag, which has remarkable environmental protection features. Light, easy to transport and construct, suitable for building walls of public and residential buildings. Background technique [0002] High-titanium slag is a kind of TiO produced by smelting pig iron with vanadium-titanium magnetite. 2 Industrial solid waste with a content of more than 15%. The molten blast furnace high titanium slag is subjected to water quenching and rapid cooling to form water quenched granulated blast furnace high titanium slag. Grinding water-quenche...

Problems solved by technology

In the existing technology, the production of sintered bricks not only consumes a large amount of natural minerals and cultivated land resources, but also consumes high energy consumption and high emissions, and sintered brick products are being gradually banned in China; the production of ordinary concrete blocks consumes relatively little energy and emissions, but consumes a large amount of Cement, natural sand and gravel aggregates, etc., and their density is high, the weight of a single block is large, and it is not easy to transport and construct; lightweight aggregate concrete blocks overcome the problems of high density and self-heaviness of ordinary concrete blocks, but the production capacity of light aggregate High consumption and consumption, expensive
