Abstract

A porous building block is made up of cement, powdered coal ash and fire-free light haydite under the existence of foaming agent without burning. It features very low contraction percentage, light weight and low cost. It is suitable for building walls.

Description

Production of non-sintered porous flyash and ceramsites blocks
The invention belongs to material of construction, be specifically related to a kind of production of non-sintered porous flyash and ceramsites blocks.
Traditional materials for wall is clay brick mostly, has used more than 2,000 year in China.Clay brick uses clay in a large number, destroys and ploughs, and consumes a large amount of energy again.Therefore developing novel materials for wall replacement clay brick is inexorable trend.The cellular concrete light material that people have now developed, because cost is higher, dry shrinkage is also big, easily splits, and is restricted in the use.
The object of the present invention is to provide the production of non-sintered porous flyash and ceramsites blocks that a kind of cost is lower, drying shrinkage is little.
Production of non-sintered porous flyash and ceramsites blocks of the present invention is characterized in that may further comprise the steps successively:
Cement and flyash cement and the mixture of fly ash by 1: 5～10 (weight) mixed, after stirring is mixed and made into the cement, flyash ball with water in pan-pelletizer, be that the burning-free flyash haydite was made in maintenance in 25～30 days in 18～22 ℃, the curing room of humidity under 85～95% in temperature;
Portion (weight) cement and 3～5 parts of (weight) flyash are mixed, under stirring condition, add water 1.3～2.5 parts (weight) and make the cement, flyash slip, add 0.005～0.01 part of (weight) foaming agent again and make cement, flyash foam slip;
Press the burning-free flyash haydite: the weight ratio of cement, flyash foam slip=1: 0.8～2, in cement, flyash foam slip, add the burning-free flyash haydite of making as stated above, stir, mix, send into mould, at 60～90 ℃, humidity is maintenance 10～20 hours under the wet heat condition more than 95%, and the demoulding becomes base; Be that 18～22 ℃, humidity are 85～95% times maintenances 25～30 days in curing room in temperature again.
The invention main points of production of non-sintered porous flyash and ceramsites blocks of the present invention are to make earlier the burning-free flyash haydite, make porous building-brick with this haydite as raw material then.When the actual production haydite and thereafter be the raw material production porous building-brick with the haydite time, except cement and flyash, also can add an amount of used foam plastics or slag through pulverizing, to reduce production costs or to improve the performance of product, general used foam plastics or scoriaceous addition are the 5%--20% of cement and flyash volume.
Non-sintered porous flyash and ceramsites blocks with method production of the present invention, because the burn-free cement lytag of making to go ahead of the rest is as preparation raw material, this haydite is stable in the setting and harden post shrinkage, therefore, the non-sintered porous flyash and ceramsites blocks of being produced, drying shrinkage reduces greatly, is particularly suitable for doing materials for wall.Owing in the process of making non-sintered porous flyash and ceramsites blocks, used foaming technique, make product reach the requirement of high-strength light, construction cost has been saved in the deadweight that has alleviated buildings greatly.A large amount of flyash that use had both utilized industrial waste in the production, helped environment protection, had reduced cost again, compared with similar products, reduced cost about 1/3rd.
Embodiment one
Make haydite: with 150 kilograms of cement, after 850 kilograms of flyash mix, being mixed and made into the cement, flyash ball with water in pan-pelletizer, being transported in the curing room, is that 20 ℃, humidity were made the burning-free flyash haydite in 28 days 90% time maintenance in temperature;

Above-mentioned foam joined by 100 kilograms of cement, 300 kilograms of flyash, 180 kg of water mix in the slip that stirs, agitation as appropriate obtains the foam slip, add 500 kilograms of haydites making as stated above, the lytag cellular concrete mix that after fully stirring, obtains, inject the mould of 390 * 190 * 190mm, be maintenance taking-up after 10 hours under 95% the condition, the demoulding, normal curing 28 days at 85 ℃, humidity, unit weight 900Kg/mn 3, ultimate compression strength 7.0MPa (mean value) the finished product building block.
Embodiment two
Make haydite: using 120 kg cement, after 880 kilograms of flyash mix, be mixed and made into the cement, flyash ball with water in pan-pelletizer, be transported in the curing room, is that 22 ℃, humidity were made the burning-free flyash haydite in 28 days 95% time maintenance in temperature;
Make foam: 100 gram spaonin powder foaming agents are mixed the abundant stirring in back with 40 ℃ of hot water of 1400 milliliters, obtain foam.
Above-mentioned foam joined by 80 kilograms of cement, 320 kilograms of flyash, 180 kg of water mix in the slip that stirs, agitation as appropriate obtains the foam slip, add 600 kilograms of haydites making as stated above, the lytag cellular concrete mix that after fully stirring, obtains, inject the mould of 390 * 190 * 190mm, be maintenance taking-up after 15 hours under 85% the condition, the demoulding, normal curing 28 days at 70 ℃, humidity, unit weight 900Kg/m 3, ultimate compression strength 6.0MPa (mean value) the finished product building block.
