Abstract
The present invention relates to a polymer modification mortar patching material for fast patching damaged concrete. The present invention uses ordinary cement or early strength cement as major raw materials, uses butadiene styrene rubber as modification components, and uses sodium carbonate and triethanolamine as accelerating agents to be prepared according to a certain mixture ratio. The present invention has the advantages of high early strength and high durability, can be widely used for patching engineering of old concrete, and is suitable for salvaging engineering with high requirements on the bending strength of patching materials, high requirements on the adhesive strength of the old concrete and patching time dimension, such as concrete roads, bridge floors, airport runways, etc.
Description
Technical field
The invention belongs to building material technical field, be specifically related to cement and polymkeric substance be main raw material preparation be used to repair damaged concrete polymer-modified cement mortar.
Background technology
Though concrete and skeleton construction are with durable in use and celebrated, but improper because of designing, construction quality is bad or the influence of environment for use of living in, as chlorion corrode, factor such as freezing and carbonization and cause damage, though these damages are shallow surface at first, yet As time goes on, they can extend to the endothecium structure material, influence the work-ing life of buildings, even influence the security of structure, thereby the concrete that has damaged is repaired is very necessary.The kind of concrete repair material is a lot, mainly contain the various synthetic resins of organic class and short-term strength cement, super-early strength cement, accelerated cement and mortar thereof, the concrete of concrete and mineral-type thereof, in addition the polymer cement mortar that is mixed with by this two classes material, polymer cement concrete etc.Cement class material mainly is suitable for big area and repairs because of it is cheap, wherein early strong, super-early strength cement can be used for quick repairing.But the fragility of this class patching material is big, splitting resistance is poor, some durability index are all relatively poor as impermeability, frost resistance, wear resistance etc., especially the cohesive force between this class patching material and the old concrete is very low, after it is stressed, be easy to come off, therefore, be not suitable for adopting this type of material for the higher occasion of life requirement.Various synthetic resins mortars or concrete generally all have the favorable durability energy, and be also higher with the cohesive strength of old concrete substrate, but this class material and normal concrete are distinct two kinds of materials, and both Young's modulus and thermal expansion coefficient difference are very big.When this type of material is used to repair old concrete, if both interfaces are not handled, under external force, easily produces bigger stress in the interface region and damage.In addition, the price of this type of material is more expensive, has limited its application to a great extent.Comparatively speaking, the polymer modification mortar or the concrete that are composited by organic materials and inorganic materials, have concurrently organic and advantage inorganic materials, has the favorable durability energy, also has good cohesive strength with old concrete, price is not high yet, thus be a kind of comparatively effectively, also be the patching material that better development prospect is arranged.At present, the kind of polymer-modified cement mortar patching material has emulsion modified sand-cement slurry such as acrylate, polyvinyl acetate (PVA) and chloroprene rubber.It is reported that these patching materials all have good effect in the concrete repair engineering, is that strength development is slower but these materials have a common characteristic, has the quick fix engineering of particular requirement or salvaging to seem powerless for some.For this reason, a kind of new polymers-cementitious composite patching material that can be used for quick fix engineering of exploitation is very necessary.
Summary of the invention
The objective of the invention is to develop a kind of excellent property, can be used for repairing fast damaged concrete polymer modification mortar patching material and interface treating agent thereof.
The patching material in quick modified polymer that the present invention proposes, adopting Portland cement or short-term strength cement is main raw material, is modified component with styrene-butadiene rubber(SBR), is that promotor prepares with yellow soda ash, trolamine, its component prescription by weight is as follows:
Silicate cement or sulplo-aluminate short-term strength cement 100
Quartz sand 50-500
Yellow soda ash 0.5-5
Trolamine 0.5-5
SBR emulsion 5-50
Water 10-60
Its more excellent component proportioning by weight is as follows:
Silicate cement or sulplo-aluminate short-term strength cement 100
Quartz sand 100-400
Yellow soda ash 1-3
Trolamine 1-3
SBR emulsion 10-30
Water 20-50
The preparation method of the patching material that the present invention proposes is as follows: take by weighing cement, quartz sand and yellow soda ash, trolamine, SBR emulsion and water respectively by weight; With trolamine, SBR emulsion and water pour into stir in the container stand-by; Cement, quartz sand and yellow soda ash are poured container into and are stirred, and trolamine, SBR emulsion and water mixed liquid add in whipping process, stir promptly to get this patching material in 3-8 minute.
The patching material that the present invention proposes also can be used as interface treating agent.
This patching material in quick modified polymer characteristics:
Its bonding component adopts short-term strength cement or material to add early strong, the short component of coagulating in forming, and has quickened condensing and hardening of cement, has overcome the early strength deficiency on the low side of general polymer modified mortar in the past, and early strength is greatly improved; Adopt polymer emulsion that sand-cement slurry is carried out modifying function simultaneously, make patching material improve greatly, compare that the folding strength of this polymkeric substance mending mortar increases substantially with conventional cement mortar to the cohesive strength of old concrete, fragility reduces significantly, and weather resistance also is improved.Therefore, this patching material can be widely used in the repairing work of old concrete, be particularly useful for to the patching material folding strength have relatively high expectations, bigger with the old concrete cohesive strength, the engineering of repairing time requirement is arranged again simultaneously, as concrete road surface, bridge floor, salvagings such as airfield runway.
The using method of this polymer modification rapid-patching motar:
(1) cuts the loose concrete of concrete surface,, remove fragment, the dust of concrete surface with machinery or other material cleaning concrete surface;
(2) the suitable moistening concrete surface that needs repairing of water, but the ponding that do not have;
(3) prepare this patching material, can suitably increase and decrease sodium carbonate amount and water consumption according to temperature Change, construction requirement;
(4) build the patching material that has prepared;
(5) surface is floating, and natural curing gets final product.
