Abstract
The invention discloses concrete small size hollow building block formula, described formula comprises flyash, coal gangue, waste residue, mine tailing, unslaked lime, cement, stone ash, wherein weight percent flyash 40%, coal gangue 10%, waste residue 20%, mine tailing 11%, cement 11%, unslaked lime 6%, stone ash 2%.The present invention adopts coal gangue subculture to replace clay as brick-making raw material, can farmland saving; During steamed brick, utilize the combustiblematerials of coal gangue itself, can coal be saved.Utilize coal gangue can turn waste into wealth, fully utilize, contaminated solution.
Description
Technical field
The present invention relates to building material technical field, specifically belong to concrete small size hollow building block.
Background technology
Along with people are to the raising of building energy conservation, living environment attention degree, industrial solid castoff instead of clay makes material of construction, because its environmental protection practicality more receives the concern of people, has occurred the fragment of brick such as fly ash baking-free non-steaming brick, powder ash air-entrained concrete brick.But all kinds of brick of powdered coal ash used at present, because batching is comparatively complicated, needing to add admixture increases consolidation force, and improve its intensity, in technique, lime mixing ratio is not high.For fly ash building block, due to adding of additive, cause the raising of its cost, concrete increase, cause the increase of weight, economic benefit declines and to mix ash quantity not high.Therefore, need badly a kind ofly highly mix ash quantity and low cost, building block that quality is light solves above problem.
Summary of the invention
The object of this invention is to provide concrete small size hollow building block, adopt coal gangue subculture for clay as brick-making raw material, can farmland saving; During steamed brick, utilize the combustiblematerials of coal gangue itself, can coal be saved.Utilize coal gangue can turn waste into wealth, fully utilize, contaminated solution.
The technical solution used in the present invention is as follows:
Concrete small size hollow building block, described block material comprises flyash, coal gangue, waste residue, mine tailing, unslaked lime, cement, stone ash, wherein weight percent flyash 40%, coal gangue 10%, waste residue 20%, mine tailing 11%, cement 11%, unslaked lime 6%, stone ash 2%.
Described flyash, coal gangue adopt F class NO:HB2008, and wherein fineness, water ratio are all less than the flyash that 12, CaO content is less than 10, and wherein the content of flyash, coal gangue reaches more than 70%.
Described cement adopts P.042.5 level silicate in bulk, and Appearance Visual does not have the cement of obvious foreign material.
Described waste residue wherein calcium hydroxide content is greater than 85%, and water-content is less than 2%, and particle is less than 10 microns, and surface-area is more than or equal to 13 ㎡/g.
Concrete small size hollow building block technique 1. computation weigh, cement, slag, stone ash, mine tailing, coal gangue, flyash are sent into batch hopper through weighing balance through worm conveyor respectively, wherein according to stone ash 45%, flyash 40%, river sand 10%, other ratios of 5%.
2. mix and blend, after raw material mixing, be transported to digestion funnel, add water mix and blend together, and the ratio that adds water carries out proportioning according to the humidity of sand, and raw material can not be excessively wet, otherwise not easily compression moulding
3. compression moulding, mixing stock after fully stirring is transported to QFT11-15 type automatic block press by rotary conveyor, pressure is regulated by main control system, by at high temperature, under the environment of high humidity, the calcareous composition in compound and siliceous composition etc. are had an effect, generate hydrate product, obtain some strength and various performance, vibrations compression moulding, finally forms work in-process.
4. maintenance, the work in-process of compacting are put with automatic palletizing machine, by fork truck, manually cross car and push to curing kilns, carry out maintenance.Regularly water within preserving period, to prevent hollow brick due to reaction after raw material mixing, lack of water cause burning out, dry and cracked.Goods, through carrying fork truck, artificial code heap, complete maintenance.
5. shaping end, the normal concrete small hollow block that maintenance terminates leaves finished product stockyard in, is transported to construction site by special distribution vehicle.
Compared with the prior art, beneficial effect of the present invention is as follows:
The present invention adopts coal gangue subculture to replace clay as brick-making raw material, can farmland saving; During steamed brick, utilize the combustiblematerials of coal gangue itself, can coal be saved.Utilize coal gangue can turn waste into wealth, fully utilize, contaminated solution.
