Abstract
The invention discloses a method of making non-burnt brick by using converting waste residue. With the research on particle matching, the additive is used to change the activity of the free-calcium oxide. The method includes the following procedures: crushing- sieving- material mixing- press forming- mould removing and shade-drying. The invention makes full use of the converting waste residue resources so that the environmental pollution is reduced. The index of the non-burnt brick made by using the method are: bending strength 4.51-5.02MPa, compression strength 38-38.75MPa, body density 2.66-2.67g/cm3, porosity rate 25.4-24.4 percent, which all exceed standard requirements of the product. In addition, the anti-hydration index and anti-freezing index of the non-burnt brick completely meet the requirements.
Description
Technical field
The present invention relates to the production method of construction material, especially a kind of method of utilizing the non-burning brick brick of revolving furnace steel slag production high strength.
Background technology
Produce non-burning brick raw material at present and mainly adopt coal-fired slag, metal tailings, gangue, oil shale etc., be affected because raw material limits the intensity of this brick.Revolving furnace steel slag has characteristics such as hardness height, internal friction angle are big, is fit to produce construction material.But, produce sclerosis and volumetric expansion owing to contain the free calcium oxide aquation in the revolving furnace steel slag, slag is difficult to as renewable resource utilization.Also do not find about utilizing revolving furnace steel slag to produce non-burning brick report at present.
Summary of the invention
The present invention is by the research of particle coupling, changes the activity of free calcium oxide in the slag with additive, and a kind of method of producing non-sintered brick with revolving furnace steel slag is provided.
The non-burning brick method of production provided by the invention may further comprise the steps:
A. broken, it is broken that revolving furnace steel slag is put into jaw crusher, particle size after cracking≤5mm;
B. screening is sieved the slag after the fragmentation respectively by 5～3mm, 3～1mm and three kinds of different-grain diameters below the 1mm, places respectively;
C. batch mixing, varigrained slag 5～3mm 40%, 3～1mm25%, 1mm following 20% mix with cement 15% or 1: 1 ratio mixture 15% of cement and waterglass, add water and stir;
D. compression moulding is put into non-burning brick hydraulic forming machine with the material that mixes and is pressed into the brick type, and hydraulic press pressure is controlled at 50-60t, evenly gives and presses, and when reaching predetermined pressure, stops pressurization, the value of keep-uping pressure half a minute;
E. with non-burning brick the piling up after the moulding, dry in the shade.
The non-burning brick method of production provided by the invention is compared with existing method, and its beneficial effect is embodied in following two aspects:
1. make full use of the revolving furnace steel slag resource, reduced environmental pollution;
2. the non-burning brick anti-folding of producing with this method reaches 4.51～5.02MPa, and resistance to compression reaches 38～38.75MPa, the close 2.66～2.67g/cm of body
3, the porosity 25.4～24.4%, above index has all surpassed the product standard requirement.Non-burning brick in addition anti-aquation, freeze proof index meet the requirements fully.
The specific embodiment
A. broken, it is broken that revolving furnace steel slag is put into jaw crusher, particle size after cracking≤5mm;
B. screening is sieved the slag after the fragmentation respectively by 5～3mm, 3～1mm and three kinds of different-grain diameters below the 1mm, places respectively;
C. batch mixing, varigrained slag 5～3mm 40%, 3～1mm25%, 1mm following 20% mix with cement 15% or 1: 1 ratio mixture 15% of cement and waterglass, add water and stir;
D. compression moulding is put into non-burning brick hydraulic forming machine with the material that mixes and is pressed into the brick type, and hydraulic press pressure is controlled at 50-60t, evenly gives and presses, and when reaching predetermined pressure, stops pressurization, the value of keep-uping pressure half a minute.
E. with non-burning brick the piling up after the moulding, dry in the shade.
