Problems solved by technology

Chinese patent application 87108093.1 "Manufacturing method of slag bricks for construction" uses construction waste as the main raw material, but after the bricks are formed, they still need high-pressure steam curing, which consumes a lot of energy, costs high, and the production equipment is complicated, so it is difficult to popularize

Abstract

The baking-free slag brick is produced with building slag, inferior stone, cement with water-reducing agent in 1-2 % added, flash and lime. The production process includes the steps of: crushing andgrinding material, mixing, pressure molding at the pressure of 170-200 kg / sq cm to form adobe, and curing of the adobe at temperature over 0 deg.c for over 15 days. The utilization of building slag can reduce pollution and lower cost.

Description

(1) Technical field [0001] The invention relates to a building block and a manufacturing method thereof, in particular to a burning-free waste slag brick and a manufacturing method thereof. (2) Technical background [0002] Traditional clay bricks use a large amount of clay for firing, which consumes a lot of energy, destroys fields and occupies land, and is not conducive to environmental protection. The general cement bricks are formed by mixing gravel, sand, cement and chemical additives with water and vibrating. Although it is non-burning, it not only has high cost, but also has a rough surface and poor compactness, which affects its use. [0003] There are many kinds of waste slag bricks with cinder or slag as raw materials, such as Chinese patent application 02100218.5 "unfired hollow brick", which uses quicklime, burned coal gangue, slag, cement clinker, clay and boiler slag as raw materials; 01102954.4 "a Process method for rapid production of fly ash blocks or fly ...
