Abstract
Foamed concrete series products have the fine qualities of light weight, low volume weight, heat insulation, heat preservation, sound insulation, fire prevention, moderate strength, crackle resistance, water permeability resistance, no pollution and the like, are the best energy-saving and environment-friendly building materials currently, are wide in use, small in investment, quick in acting, multiple in series product and large in market demand and are relatively good building materials. In order to enable the foamed concrete series products to be more complete and meet the requirements of construction engineering on higher compressive strength, the compressive strength is required to be further improved. A novel hardening agent is added into foamed concrete products of various different formulae, and the compressive strength of the foamed concrete products can be improved by about 30% under the condition that the usage amount of cement is not changed. On one hand, the requirements of the construction engineering on improved strength can be met, the cost for raw materials can be reduced, the requirements of manufacturers are met, and a greater profit margin is obtained, so that better benefits for the society are created.
Description
Technical field
The present invention is for a kind of new Hardening agent of foam concrete block production process.
The ultimate compression strength that is specifically related to cellular concrete product can improve 30% left and right, meets the requirement of manufacturer: reduce cement consumption, reduce costs, improve block strength.
Background technology
Minstry of Housing and Urban-Rural Development of People Republic of China (MOHURD) proposes energy-conservation 60% target call to construction work, need to all carry out heat insulating to building roof, metope, body of wall, ground and process, and needs to adopt the very low energy-saving type heat-preserving heat-insulation light material of thermal conductivity.The foamed concrete roofing layer of the insulating brick of using as Roof Insulation Design, warming plate, cast-in-place notes; The warming plate that metope insulation design is used, insulating brick, insulation Art Stone; Light block, the cast-in-situ thermal-insulated wallboard of wall thermal insulating design use; The insulating foam concrete floor tile that ground insulating is used, cast-in-place foamed concrete ground floor etc.
A concrete thermal-insulating material, excellent performance, is widely used.Its over-all properties is better than other various lagging materials, obtains the approval of the Ministry of Construction, supports to promote energetically.
Summary of the invention
At present, cement concrete admixture kind is a lot, and various hardening accelerator, reinforcing agent, accelerating chemicals formula are also a lot.For various reasons, the use of these admixtures is all difficult to the result that reaches satisfied.
By the on-the-spot examination investigation of manufacturer, consulted again a lot of technical information, design a kind of new Hardening agent.Lab scale is adjusted formula rate repeatedly, existing 30% the re-set target of gaining in strength that substantially can reach.

Embodiment
The ultimate compression strength of foamed concrete series of products is from two parts
1, cement natural characteristics, the intensity after solidifying
Silicon-dioxide and calcium oxide, under hydration heat condition, generate high-intensity hydrated calcium silicate concrete product.
2, even careful the entering in cement grout of a large amount of foams, forms a large amount of airtight vesicular structures in the process that thes cement solidifies, and a large amount of bubbles make cement grout workability, mobility better, reduce the bleeding segregation of cement slurry, improve plasticity-, and make volumetric expansion, prevent that surface from subsiding.
Also, due to the effect of tackifier, thickening material, suds-stabilizing agent in whipping agent formula, guarantee the stability of liquid cement material cast, also kept the intensity stabilization after cement solidification.
The ultimate compression strength of cellular concrete product also should improve again, to be applicable to the technical requirements of construction work.
1, foaming agent has strong delayed coagulation, delays cement solidification performance, and the intensity after cement solidification is incurred loss.
2, the slurries of cement concrete enter the foam of a large amount of careful sealings, can reduce concrete strength.The concrete that water cement ratio is identical, air content is large, reduction many; Air content is identical, and the large strength decreased of water cement ratio clearly.
Whipping agent adds workability, the mobility that can improve cement grout, also has water-reducing effect.
Keep former cement consumption, added less mixing water, reduce water cement ratio and increased intensity.
This way has just been done necessarily and has been made up loss of strength.
In order to supply the loss of strength of foamed concrete.Patent of the present invention proposes another kind of compensation process, i.e. a kind of new Hardening agent redesigns formula, Recompounded multielement, and science collocation, as a kind of new variety of admixture, joins in cement grout, performance dual-use function, early strong and Hardening is carried out simultaneously.Actual production proves, can improve intensity 30%.
Claims (3)
1. the admixture of a new foamed concrete series of products.
Formula diversity, the plyability of new Hardening agent.
The multiple inorganic chemistry material of mainly take is basic recipe.Specifically chlorination salt is main body.
When foamed concrete series of products is produced, adding of this stiffening agent, can bring into play morning by force and the dual-use function of Hardening to the curing of cement, reaches the requirement that improves goods ultimate compression strength.
2. a kind of new Hardening agent according to claim 1
Its main ingredient: butter 85～90%
Inorganic sodium compound 10～15%
Auxiliary: 3～2%
Muriate is that master's villaumite kind is a lot.
Cl ion chemistry character in inorganic villaumite is active, and active good, seepage force is strong.
Other inorganics of inorganic chlorine salt binding, organism (trolamine) form the concrete admixture of various cement.
As: hardening accelerator, frostproofer, reinforcing agent etc.
3. according to a kind of new Hardening agent described in claim 1,2
Principal character: the multiple components preparation of this formula is Powdered, and raw material is easy to get.Formula reasonable combination, various raw materials mix in proportion, become mixture available.
New a kind of Hardening agent is easy to use, and the intensity of goods improves 30%, enough meets a kind of Hardening agent that various engine requests are new owing to being that powder evenly mixes entirely, easy to use.It is all convenient to pack, store and transport, cost.
