Abstract
The invention relates to an electric furnace steel slag composite porous brick which includes the following raw materials, by weight: 40-55 parts of electric furnace steel slag powder, 10-20 parts of feldspar powder, 6-10 parts of Portland cement, 20-35 parts of water, and 10-15 parts of expanded glass bead powder. The electric furnace steel slag composite porous brick is prepared through a method including the following steps: 1) performing magnetic separation iron removal to the electric furnace steel slag powder until iron content is less than 2% and the granular size is 3-10 mm; 2) mixing the feldspar powder, the Portland cement and the electric furnace steel slag powder, adding water and the expanded glass bead powder, and stirring the mixture uniformly; and 3) pressing the raw materials which is aged in the step 2) under 3-10 MPa for 4-6 h, and performing maintenance to produce the steel slag composite porous brick.
Description
Technical field
The present invention relates to building material field, be specifically related to a kind of electric furnace slag composite porous brick.
Background technology
Low-carbon economy, environment protection, resource recovery are the emphasis research topics of society Economic development.China is as steel-making big country, and electric furnace slag recovery utilization rate is low and many as pavior.At present, the research of electric furnace slag performance and comprehensive utilization mainly concentrates on converter electric furnace slag aspect, relatively less to the research of electric furnace slag.Electric furnace slag is become the raw material of building materials industry by the present invention, provides a kind of electric furnace slag composite porous brick, realizes the recovery of electric furnace slag high added value, realizes low-carbon economy, environment protection, resource recovery, economic benefit depositing.
Summary of the invention
Object of the present invention is just to provide a kind of electric furnace slag composite porous brick, to overcome the deficiencies in the prior art.
The present invention adopts following proposal to realize:
A kind of electric furnace slag composite porous brick, comprises the raw material of following weight part: electric steel ground-slag 40-55, Feldspar Powder 10-20, silicate cement 6-10, water 20-35, expanded glass microballon powder 10-15.
The manufacture method of described a kind of electric furnace slag composite porous brick, comprises the following steps:
(1) after electric steel ground-slag is through magnetic separation iron, iron level is less than 2%, and particle diameter is 3-10mm;
(2) by Feldspar Powder, silicate cement, electric steel ground-slag mixing after, then add water, expanded glass microballon powder stirs;
(3) by raw material good for step (2) ageing at 3-10MPa pressure time 4-6h, obtained finished product slag perforated brick after maintenance.
The present invention processes the electric furnace slag composite porous brick good water permeability obtained, and yield rate reaches more than 85%.
Embodiment
Below by specific embodiment, the present invention is further described.
