Description
Technical field
The invention belongs to the technical field of magnesium phosphate cement, relate to a kind of preparation method and application thereof of Interface enhancer, be specifically related to a kind of preparation method of Interface enhancer and improving the application in magnesium phosphate cement concrete and Deteriorated concrete pavement cohesive strength.
Background technology
Magnesium phosphate cement is usually formulated according to a certain percentage by dead burned magnesia and phosphoric acid salt, slow setting component, have fast hard, early strong, shrink the features such as little, be very suitable for concrete road surface and the isostructural Rapid-Repair of industrial premises.But due to main ingredient in magnesium phosphate cement market value costly, cause preparing the cost of magnesium phosphate cement also than high several times even ten several times of Portland cement, thus greatly limit the widespread use of magnesium phosphate cement.In order to effectively reduce material unit cost and the overall performance improving material, people often tend to lower-costly gathering materials, mineral admixture replaces most magnesium phosphate cement powder and prepares mending mortar or concrete, now in order to ensure the workability of patching material, its water consumption also can correspondingly improve.Usually, be different from Portland cement, the magnesium phosphate cement slurry of excellent performance is a class low water binder ratio system, and its amount of gathering materials that can effectively wrap up comparatively Portland cement slurry will be lacked.Therefore, increasing gathers materials consumption and improve water consumption causes disadvantageous effect to the various aspects of performance of magnesium phosphate cement concrete repairing material possibly, especially can weaken and repair vital interfacial bond property to damaged concrete.Usually, when interfacial adhesion is comparatively weak, destruction and the failure phenomenon of the concrete structure through repairing often occur on new-old concrete interface.Existing investigation and application shows, the interfacial adhesion of magnesium phosphate cement and old concrete is gathered materials and to affect significantly with factors such as gelling material mass ratio (a/b) and water-cement ratios (w/b).Under the same conditions, the mortar 6 h cohesive strength of a/b=0.5 can reach 3.5 more than MPa, and 6 h cohesive actions of the mortar of a/b=1.5 and concrete substrate are very weak, undercapacity 1 MPa; And for example during w/b=0.10,1 d and the 28 d cohesive strengths of magnesium phosphate cement can reach 6 Mpa and 10 more than MPa respectively, and when water-cement ratio is increased to 0.18, all kinds of mechanical properties of hardened paste decline all in various degree, especially the most obvious with the reduction of interface binding intensity, 1 d and the 28 d cohesive strengths of slurry all decrease beyond 70%.When magnesium phosphate cement the reinforcement of concrete is in time repairing, if its cohesive strength with old concrete is lower, guarantee repairing quality must be difficult to.
In the Rapid-Repair of reality, be again on active service to engineering, the most basic requirement is, the ultimate compression strength of patching material can reach 30 more than MPa, bending resistance cohesive strength is greater than 3.0 MPa.For the repairing of small area, adopt the mortar that magnesium phosphate cement is starched only or sand using amount is less, now by regulating the proportioning of magnesium phosphate cement patching material can be easy to meet above-mentioned reparation requirement.And the repairing of larger area can consider concrete batching usually, because slurry relative content in unit volume reduces, cause the slurry amount of new-old concrete near interface to be also relatively short of, cannot ensure that slurry fully infiltrates old basal body interface, thus greatly affect the early stage adhesive property of patching material; In concrete, slurry water-cement ratio is general comparatively large simultaneously, so also can seriously undermine mending concrete viscosifying power.In this case, when adopting magnesium phosphate cement concrete to carry out the repairing of generous amount, the development of very possible Presence of an interface early stage cohesive strength is slow and later stage cohesive strength is not high and then occur the risk of repairing inefficacy.For improving the interfacial bond property of new-old concrete, to a certain degree can be improved the cohesive action of new-old concrete by the roughness increasing basal body interface, but it is very unobvious to improve effect; Also can improve the interfacial adhesion of new-old concrete to interface plant anchor process, but operating process is slightly aobvious complicated.
The most outstanding advantage of magnesium phosphate cement can form intensity fast after having constructed, and later stage mechanical property is better than old matrix.Prior art measure can ensure that magnesium phosphate cement system merely meets the requirement of repairing work to its performance such as workability or cohesive strength.But reducing on the basis of material cost as far as possible, how to make to gather materials consumption and the larger magnesium phosphate cement concrete of water-cement ratio meets the requirement of cohesive strength when repairing fast Deteriorated concrete pavement, does not also occur relevant simple and effective technological method and approach at present.

Table 2 the inventive method and pedestal method are on the impact of magnesium phosphate cement patching material intensity and cost
As can be seen from table 1 and 2, for 1# and 2#, 3# test specimen, adopt method in the past, when sand consumption is less, the early stage cohesive strength of magnesium phosphate cement mortar and old matrix, the early anti pressured intension watering building body are all higher, meet the requirement of quick fix engineering completely, but now the cost of material is the highest; When the consumption that gathers materials increases by 1 times, after water-cement ratio suitably improves, the corresponding minimizing of gel material content in unit volume, now material resulting cost can reduce about 32%, but also bring negative impact, that is the early strength of magnesium phosphate cement concrete and old matrix significantly declines, particularly evident with interface binding intensity; And on basal body interface, spray the water-cement ratio that one deck water can reduce interface slurry, be more unprofitable to the development of cohesive strength; Compare 1# test specimen, 6 h cohesive strengths of 2# test specimen and ultimate compression strength decline 84.9% and 37.5% respectively, along with development of age to 1 d, although the ultimate compression strength of watering building body can rise to suitable scope, but interface binding intensity is still very low, and this obviously cannot meet the quick military service of repairing work.
For 4#, 5#, 6# and 7# test specimen, adopt method of the present invention, previously prepared Interface enhancer, then be in good time coated on old basal body interface, compare 1# test specimen, 5#, 6# and 7# test specimen suitably improves gather materials consumption and water-cement ratio in magnesium phosphate cement concrete, now the one-tenth instinct of material reduces more than 25%, to a certain degree decline though 6h and 1d interface binding intensity and ultimate compression strength have, but still the requirement of quick fix engineering can be met, and after 7d cohesive strength is closely; But compare 2# and 3# test specimen, in good time 4#, 5#, 6# and 7# test specimen of coating Interface enhancer early stage and later stage interfacial bond property be improved significantly.Therefore, the use of Interface enhancer, effectively can improve the interfacial bond property between magnesium phosphate cement concrete and old matrix, can not affect the entire compression intensity of watering building body.
In sum, the factors such as consumption, water-cement ratio, dead burned magnesia and phosphatic ratio of gathering materials have important impact to performances such as the concrete interface binding intensities of magnesium phosphate cement; The phosphate content that interface slurry amount is fuller, water content is lower, high is all conducive to magnesium phosphate cement patching material and old matrix forms good bonding interface.The present invention is being unlikely to remarkably influenced patching material early strength and is ensureing on the basis of workability, to a certain degree reduce the preparation cost of such patching material, improve adhesive property between novel concrete and old matrix by preparing and applying Interface enhancer again, realize the quick reparation of engineering.
