Abstract

The invention belongs to the technical field of building materials and relates to an environment-friendly paving building material. Algae-residue combustion ash paving bricks are prepared by the following raw materials in percentage by weight: 40 to 60 percent of algae-residue combustion ash, 30 to 50 percent of river mud or flyash and 10 percent of fine aggregate. The raw material of the algae-residue combustion ash paving bricks is the algae-residue combustion ash, the doping amount is large and the problem of algae-residue treatment is better solved. The algae-residue combustion ash replaces clay, so that land resources are saved, the waste is changed into treasure, the social, environmental and economic benefits are good, and the national environmental protection policy of saving energy and reducing emission is followed.

Description

A kind of algae-residue combustion ash pavior brick
Technical field
Patent of the present invention belongs to building materials technology field, is specifically related to utilize the algae-residue combustion ash to make pavior brick for raw material.
Background technology
Algae-residue is the discarded body refuse after the eutrophic water source water treatment.Contain a large amount of organic pollutants, inorganic impurity and a small amount of heavy metal in the algae-residue.In a single day algae-residue is dealt with improperly, will cause the degree of depth of environment to pollute.Present stage, the treatment process of algae-residue mainly was landfill, burning etc., so not only caused secondary pollution also will take a large amount of soils, waste energy.At present algae-residue is not also had effective processing means, therefore, how effectively to handle algae-residue and will obtain more concern.
At present, useful resources such as a large amount of clays of making material consumption of pavior brick and cement are unfavorable for protecting environment.Corresponding to national energy-saving and emission-reduction policy, utilize waste to make pavior brick, can economize on resources, reduce discharging, become the optimal path of making pavior brick.Directly to make pavior brick respond well for raw material though utilize algae-residue, but the algae-residue utilization ratio is lower.Correlative study shows and utilizes algae-residue to make pavior brick for raw material that its algae-residue utilization ratio is about 20%.And utilize combustion ash to produce pavior brick, the algae-residue utilization ratio can reach 50% even higher.This has not only improved the utilization ratio of algae-residue, and has replaced clay to a greater extent, has saved land resources.
The algae-residue combustion ash is carried out chemical analysis, and the result shows that wherein main component is an inorganics, mainly is silicon, aluminium, iron, calcium etc.Algae-residue combustion ash and clay component are similar, therefore can be used as the pavior brick raw material.The pavior brick mechanical property of utilizing the algae-residue combustion ash to cooperate flyash or river silt to make is good, intensity is high, can reach the pavior brick application standard.The algae-residue combustion ash cooperates other waste materials to produce the handling problems that pavior brick has solved algae-residue, has reduced waste discharge, has protected environment.
Summary of the invention
For solving the handling problems of algae-residue, the invention provides a kind of is the pavior brick of raw material with the algae-residue combustion ash.
The present invention utilizes raw materials such as algae-residue combustion ash, river silt, flyash, fine aggregate to produce pavior brick.Algae-residue is handled 600 ℃ of following calcinations, remains residual ash and is the algae-residue combustion ash.Add water after algae-residue combustion ash, river silt or flyash, the fine aggregate etc. that oven dry, ball milling, screening are handled mix by a certain percentage and stir, through the ageing processing, extrusion forming in mould, the dry body after the moulding obtains pavior brick through super-dry, roasting.It is algae-residue combustion ash 40-60%, river silt or flyash 30-50%, fine aggregate 10% that algae-residue combustion ash pavior brick is made raw materials by weight.
Utilize the algae-residue combustion ash to make pavior brick, not only solved current algae-residue and handled the land occupation resource because of stacking, cause secondary pollution problem, and algae-residue volume height, the utilization ratio height.By in manufacture craft, adding fine aggregate, increase ventilation property, efficiently solve the cracking problem in compression moulding process, drying course, roasting process.Algae-residue combustion ash pavior brick is turned waste into wealth with algae-residue combustion ash substitute for clay, has saved land resources, helps environment protection, has good social benefit, environmental benefit, economic benefit, meets the environmental protection policy of current national energy-saving and emission-reduction.
