Abstract
The invention discloses modified repair mortar. The modified repair mortar is prepared by mixing sulphoaluminate cement, ordinary silicate cement, quartz sand, a complex early strength agent, a water-retaining agent, anti-crack fibers, a water reducing agent and water. According to the modified repair mortar, a sulphoaluminate cement and ordinary silicate cement mixed cementing material is adopted, the optimal mix and match proportion is selected, the early strength of the mortar is high, the setting time is proper, and construction is convenient. In addition, the complex early strength agent, the water-retaining agent, the water reducing agent and the like are added, and therefore better strength of the mortar in early stage and later stage is effectively guaranteed. The anti-crack fibers are added in the components, shrinkage deformation of the mortar is greatly reduced, when the mortar is under stress, the anti-crack fibers play an active prevention role in generation and development of cracks, the shrinkage deformation is obviously reduced, and cracks generated in the repair mortar setting and hardening processes and under stress are reduced.
Description
Technical field
The present invention relates to a kind of building mortar, be specifically related to a kind of modified mending mortar。
Background technology
At present, the domestic research to patching material is concentrated mainly on conventional epoxies mortar or resin concrete, and this type of composite is higher to the compatibility requirements of material, it is complex to prepare, cost is high, the breakoff phenomenons such as aging, the cracking that later stage Organic substance shows make the performance of patching material decline to a great extent, and most of portland cement based patching materials can not meet rapid condensation hardening, early strong requirement simultaneously。Although the sulphate aluminium cement used in some emergency works has, setting time is fast, early strength advantages of higher, but also has that later strength is shunk, setting time too fast is not easy to the shortcomings such as construction simultaneously。
Summary of the invention
Present invention aim at, it is provided that a kind of easy construction, rapid condensation is hardened, and early strength is high, and later strength shrinks little modified mending mortar, and the technical solution adopted in the present invention is:
Sulphate aluminium cement 5-10 part
Portland cement 20-30 part
Quartz sand 20-40 part
Complex accelerator 0.5-1.5 part
Water-retaining agent 0.5-1 part
Anti-crack fiber 0.5-1 part
Water reducer 0.5-1 part
Water 25-40 part。
One of preferably, complex accelerator is sodium sulfate, triethanolamine, and calcium formate is that 1:1:1 mixes according to weight ratio。
One of preferably, anti-crack fiber diameter is at the polypropylene fibre of 15-50 μm。
One of preferably, water-retaining agent is the viscosity hydroxypropyl methyl cellulose ether at 70,000-10 ten thousand mpa.s。
The present invention provides the benefit that relative to prior art: the modified mending mortar of the present invention, have employed sulphate aluminium cement, the Binder Materials of Portland cement two kinds mixing, choose the mix and match ratio of the best, intensity morning making mortar is high, and setting time is suitable for, it is simple to construction。Additionally with the addition of complex accelerator, water-retaining agent, water reducer etc. has been effectively ensured early stage and the later stage good intensity of mortar。Component with the addition of anti-crack fiber, there is reduction by a relatively large margin in Mortar shrinkage deflection, and when mortar stress, generation and the development of fracture are played positive interception by anti-crack fiber, substantially reduce contraction distortion amount, reduce the crack that mending mortar condenses in hardening process and produces during stress。
Detailed description of the invention
