Abstract
The invention discloses a production method for non-bearing concrete hollow bricks, which has the characteristic of being capable of lowering the production cost. The production method comprises the steps as follows: a. adding cement, pulverized fuel ash and high-titanium heavy cinder aggregate in a blender, wherein the total weight of the cement, pulverized fuel ash and high-titanium heavy cinder aggregate is t, and the weight of the cement is 10 percent of t, the weight of the pulverized fuel ash is 25-30 percent of t and the weight of the high-titanium heavy cinder aggregate is 60-65 percent of t; and at the same, adding water with the weight of 10-12 percent of t in the blender for blending; b. adding the blending materials in pressing equipment to be vibrated, compacted and formed into concrete hollow bricks; c. placing the formed concrete hollow bricks on a backing plate for curing for 24 hours to 48 hours; and d. stacking the concrete hollow bricks on the ground for natural curing for 28 days, thus obtaining the finished concrete hollow bricks. With the use of the production method, for the finished concrete hollow bricks, the density is low, the strength is high and the production cost can be lowered.
Description
Technical field
The present invention relates to a kind of production method of concrete structures, be specifically related to a kind of production method of non-load-bearing concrete hollow brick.
Background technology
At present, the solid waste that adopts vanadium titano-magnetite ironmaking back to produce is called high-titanium blast furnace slag, and different with the ordinary blast slag, its shrend activity is lower, is mainly used in preparation dry slag sandstone aggregate and derived product thereof at present.
Country has issued the standard of non-load-bearing concrete hollow brick in 2008, be applicable to the concrete hollow block that non-weight bearing area uses in industry and the civil buildings, the aggregate of concrete hollow block can adopt natural sandstone aggregate, and also can adopt industrial solid castoff is aggregate.
(notification number: CN1056858) proposing to adopt heavy blast furnace slag is that aggregate prepares concrete hollow block for " making the method for hollow lump from slag concret " in patent application.But there is following deficiency in it: 1. cement consumption height, and reach 15%, and need to add additives such as triethanolamine and ferrous sulfate, cost is higher; 2. need be introduced into curing kilns during maintenance and carry out steam curing, natural curing again, the maintenance operation is loaded down with trivial details; 3. shaping building block density is bigger, reaches more than the 1200kg/m3.
Summary of the invention
Technical problem to be solved by this invention provides a kind of production method of the non-load-bearing concrete hollow brick that reduces production costs.
The technical solution adopted for the present invention to solve the technical problems is: the production method of non-load-bearing concrete hollow brick comprises the steps:
Add cement, flyash and high-titanium dry slag aggregate in a, the past mixer, the gross weight of described cement, flyash and high-titanium dry slag aggregate is t, the weight of cement is 10%t, the weight of flyash is 25～30%t, the weight of high-titanium dry slag aggregate is 60～65%t, simultaneously, adding weight in the mixer is that the water of 10～12%t stirs;
B, the material behind the stirring and evenly mixing added compression-vibration shaping is a concrete hollow block in the press device;
C, the concrete hollow block after the moulding is placed into maintenance on the supporting plate, curing time is 24 to 48 hours;
D, after maintenance is finished on the carriage, the concrete hollow block pile is carried out natural curing to ground, curing time is 28 days, obtains the concrete hollow block finished product.
As optimized technical scheme, the particle diameter of described high-titanium dry slag aggregate is d, 0＜d≤15mm.
Further be in step c, supporting plate to be put to carriage concrete hollow block is carried out maintenance.
Further be that in the natural curing process in steps d, water once to concrete hollow block every day at least.
The invention has the beneficial effects as follows: the concrete hollow block that adopts the inventive method to produce has that apparent density is low, the intensity advantages of higher; The concrete hollow block 90% that production obtains adopts blast furnace slag and flyash, cost of material is lower, has avoided the pollution to environment of blast furnace slag and flyash simultaneously, and need not carry out steam curing, simplified production technology greatly, be particluarly suitable for applying in the production of non-load-bearing concrete hollow brick.
The specific embodiment
The present invention is further described below in conjunction with embodiment.
The production method of non-load-bearing concrete hollow brick of the present invention comprises the steps:
Add cement, flyash and high-titanium dry slag aggregate in a, the past mixer, the gross weight of described cement, flyash and high-titanium dry slag aggregate is t, the weight of cement is 10%t, the weight of flyash is 25～30%t, the weight of high-titanium dry slag aggregate is 60～65%t, simultaneously, adding weight in the mixer is that the water of 10～12%t stirs; Carry out the production of hollow brick by this proportioning, can guarantee that finished product is under the minimum cement consumption, under the volume of the highest high-titanium dry slag aggregate, reach suitable apparent density and intensity.
B, the material behind the stirring and evenly mixing added compression-vibration shaping is a concrete hollow block in the press device; Press device can adopt the brickmaking machine of all kinds of production hollow bricks, and adopts compression-vibration shaping, can guarantee the closely knit of concrete hollow block finished product, guarantees the compression strength of concrete hollow block finished product.
C, the concrete hollow block after the moulding is placed into maintenance on the supporting plate, curing time is 24 to 48 hours; The hollow brick of moulding just is owing to moulding good, and is yielding when mobile, thus must connect supporting plate maintenance together, maintenance 24～48 hours, after hollow brick has certain intensity, then desirable bottom plate, and direct code is put the further maintenance of row into.
D, after maintenance is finished on the carriage, the concrete hollow block pile is carried out natural curing to ground, curing time is 28 days, obtains the concrete hollow block finished product.In the general concrete product, its intensity derives from hydrated cementitious, and hydrated cementitious is a time-continuing process, generally can reach a higher value at 28 days, and hollow brick less than in the length of time should not be dispatched from the factory in 28 days.
The particle diameter of described high-titanium dry slag aggregate is d, and 0＜d≤15mm helps reducing hollow brick density and is beneficial to the demoulding.
For saving floor occupying area, in step c, supporting plate put to carriage concrete hollow block is carried out maintenance.The maintenance of putting on the shelf is beneficial to piles up multilayer simultaneously, saves floor occupying area.
For improving the intensity of hollow brick, in the natural curing process in steps d, water once to concrete hollow block every day at least.Make concrete hollow block keep moistening in the natural curing process.Concrete is in maintenance processes, and certain temperature and humidity helps promoting hydrated cementitious, makes its intensity better.
