Abstract

The invention discloses a novel regeneration brick, which relates to the field of building material. The novel regeneration brick comprises the following raw materials by weight part: 15-25 parts of sugar refinery filter mud with water content being no higher than 30%, 15-25 parts of loess, 20-30 parts of slag, 15-25 parts of concrete pieces, 10-15 parts of expanded and vitrified small balls, and 3-5 parts of sulfur-fixation azotification peculiar smell reliever. The novel regeneration brick solves the problems of low cost of resource making, light mass, anti-compression, fire resistance, and infiltration prevention.

Description

New Regenerated brick

Technical field

The present invention relates to building material technical field, especially a kind of New Regenerated brick.

Background technology

Guangxi is as the area just at high speed development, and all our undertakings are all in construction in full swing, and the demand of construction timber sharply rises.Simultaneously Guangxi is again the tap of national sugar-refining industry, produces a large amount of filter mud the like waste every year, because these sugar refinery are nearly all adopt carbonatation process production technique, to make in filter mud, except containing except large amount of organic, to be also rich in basic carbonate calcium.The current recycling mode of these filter mud of sugar refinery is mainly done fertilizer, feed, acid soil improving agent, is produced commercial lime stone etc.But because alkalescence is high, easily harden, the sales volume doing fertilizer and feed is all little.Cannot be used up so still there is a large amount of filter mud profits, cause environmental pollution.

If these filter mud of sugar refinery can be used construction timber, not only solve the problem that filter mud pollutes, also effectively make use of filter mud resource, more can provide the novel architecture material of excellent performance and reduce its cost, economic benefit, social benefit and ecological benefits can obtain effect.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of New Regenerated brick, it can solve, and filter mud of sugar refinery resource utilization produces that cost is low, quality is light, resistance to compression, fire prevention, water-impervious the problem of New Regenerated brick.

In order to solve the problem; the technical solution adopted in the present invention is: this New Regenerated brick; it is characterized in that the raw material comprising following weight part: water content not higher than 30% filter mud of sugar refinery 15 ~ 30; loess 15 ~ 25; slag 20 ~ 30; broken concrete 15 ~ 25, expanded and vitrified small ball 10 ~ 15, Gu sulphur fixed nitrogen peculiar smell removal agent 3 ~ 5.

In technique scheme, technical scheme can also be more specifically: described filter mud of sugar refinery is that the former filter mud of water content 50 ~ 70% dewaters to water content not higher than 30%, and calcium carbonate content is not less than 75%.

Further: described solid sulphur fixed nitrogen peculiar smell removal agent is made up of the calcium oxide of 94 ~ 96wt% and the salt of wormwood of 4 ~ 6wt%.

Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:

1, raw material filter mud of sugar refinery of the present invention, slag are all trade wastes, not only be rich in a large amount of calcium carbonate, organism, fiber, or the concrete admixture of high-quality, add and make use of discarded broken concrete, resistance to compression better effects if, both achieved utilization of waste as resource, again reduced cost, reached the doulbe-sides' victory of economic benefit and ecological benefits.

2, raw material of the present invention have employed expanded and vitrified small ball, and ageing resistance is strong, has the excellent performance such as thermal insulation, fire prevention, sound-absorbing, insulation.

3, the present invention after testing, and without explosion without scum, the ultimate compression strength of load face reaches 6.9MPa, is greater than GB 6.5 MPa, and 5h boils water-intake rate and saturation factor and distinguishes average out to 17.3% and 0.2, is less than GB 30% and 0.88.As can be seen here, the performance such as Novel lightweight brick resistance to compression of the present invention, fire prevention, waterproof is better.

Embodiment

Below in conjunction with specific embodiment, the invention will be further described:

Embodiment one:

This New Regenerated brick comprises the raw material of following weight part: filter mud of sugar refinery 15, loess 15, slag 20, broken concrete 15, expanded and vitrified small ball 10, the salt of wormwood 1 of the calcium oxide 2,4 ~ 6wt% of 94 ~ 96wt%.

Making method is as follows:

A, by water content be 50 ~ 70% filter mud of sugar refinery dehydration must not to dewater filter mud higher than 30% to water content;

B, the loess getting 15 weight parts, the slag of 20 weight parts, the broken concrete of 15 weight parts stir, and grind to form 150 ~ 200 order particles and obtain composite grain;

C, get 15 weight parts steps A gained dehydration filter mud, step B gained composite grain and 10 weight parts expanded and vitrified small ball, 94 ~ 96wt% calcium oxide of 2 weight parts, 4 ~ 6wt% salt of wormwood of 1 weight part mixes, and adds water and stirs make the ripe mud of adobe;

D, ripe for step C gained mud is made adobe, place 2 ~ 5 days natural air dryings, enter klining and tie 60 minutes, sintering temperature is 1200 DEG C, naturally cooling and get final product.

Embodiment two:

This New Regenerated brick comprises the raw material of following weight part: filter mud of sugar refinery 30, loess 25, slag 30, broken concrete 25, expanded and vitrified small ball 15, the salt of wormwood 2 of the calcium oxide 3,4 ~ 6wt% of 94 ~ 96wt%.

Making method is as follows:

B, the loess getting 25 weight parts, the slag of 30 weight parts, the broken concrete of 25 weight parts stir, and grind to form 150 ~ 200 order particles and obtain composite grain;

C, get 30 weight parts steps A gained dehydration filter mud, step B gained composite grain and 15 weight parts expanded and vitrified small ball, 94 ~ 96wt% calcium oxide of 3 weight parts, 4 ~ 6wt% salt of wormwood of 2 weight parts mixes, and adds water and stirs make the ripe mud of adobe;

D, ripe for step C gained mud is made adobe, place 2 ~ 5 days natural air dryings, enter klining and tie 120 minutes, sintering temperature is 800 DEG C, naturally cooling and get final product.

Brick sampling embodiment prepared detects, and by National Building Material Industrial Wall & Roof Material Quality Examing & Testing Center, detects by GB13544-2011 " sintered perforated brick and porous building-brick " standard, is reported as follows:
