Description

Ready-mixed mortar thickening plasticity-maintaining agent
Technical field
The invention belongs to building material field, be specifically related to ready-mixed mortar thickening plasticity-maintaining agent.
Background technology
Along with the raising that construction industry development of technology and civilized construction require, the mortar that system is mixed at the scene demonstrates its inherent defective day by day, and is big like construction intensity, quality is unstable, proportioning is unreasonable, contaminate environment etc.Therefore, the system mortar is mixed at the cancellation scene, adopts the premixing mortar of large-scale production (to have another name called: commodity mortar) imperative.In recent years, China's part large size city has taken up to carry out premixing mortar.The demand for development that meets cyclicity economy and conservation-minded society is used in the production of premixing mortar, and it has realized suitability for industrialized production, has guaranteed quality of stability from the source, has good operability, the on-the-spot plurality of advantages such as less, effectively improving job schedule of polluting.
Premixing mortar is divided into masonry mortar, motar, ground mortar according to the difference at building operation position.Premixing mortar can be divided into dry-mixed mortar and wet mixing mortar two big classes according to the difference of production and form of construction work.Dry-mixed mortar is claimed dry-mixed mortar again, it with the various raw materials (comprising gelling material, fine aggregate, chemical admixture) of dryness through factory accurately prepare mix evenly after, transport to the building site with packed or in bulk mode, add the suitable quantity of water mix during use and get final product.Wet mixing mortar is meant various starting material (comprising water) through preparation rationally, after carrying out batch production and producing, is transported to the building site by transportation means (using airtight tank car usually).
Premixing mortar is transported to on-the-spot the use from production; The same as ready mixed concrete, to having relatively high expectations of its serviceability, guarantee certain operable time; Mortar will have enough good workability, can carry out normal construction, operation behind blunge before initial set.Therefore, functional, the ready-mixed mortar thickening plasticity-maintaining agent that has effects such as water conservation, thickening, slow setting concurrently is the key problem in technology that guarantees the premixing mortar various aspects of performance.
In the tradition mortar, in order to improve its workability, can add the lime putty of being processed by the soaked slaking of lime usually, but there is " burning " and " underburnt " phenomenon in part lime, it is low to show as effective CaO content, generally 70~85%, does not reach 90%.In addition, burning lime hydration speed very slowly, often be mortar hardening after, it is also continuing aquation, causes mortar destruction itself, common quality defect such as be embodied in coat of plaster cracking, hollowing, come off influences construction quality.And the production of lime will consume mass energy and produce a large amount of CO 2, therefore, in order to guarantee construction quality, energy-conservation and protection environment has forbidden in mortar, mixing lime putty at present.The admixture that also has some to improve the premixing mortar performance on the domestic construction market now, but all exist some problems, the serviceability to premixing mortar that has has some improvement, but intensity is lower; The raising that has intensity, but bleeding is serious, the mortar operability is undesirable.Alternative mortar thickening plasticity-maintaining agent comparatively sophisticated, that be fit to the premixing mortar large-scale production and application is of less types on the market.
