Abstract
A modified low-alkali thioaluminate cement is prepared from thioaluminate cement, silicate cement as modifier, gypsum as modifying regulator, and other additives. Its advantages are low content of alkali, early strengthening, fast hardening, excellent surface performance, and low cost.
Description
Technical field
The present invention relates to new variety of special cement, belong to modification technology, be particularly suitable for the construction occasion of speedily carrying out rescue work with cement-based grout for common aluminosulfate cement.
Background technology
With the low basicity fast hardening concrete of high-performance is raw material, and the injection material with addition of water glass forms is widely used among the engineering construction as engineering first-aid repair, antiseepage, leakproof.In this grouting cement there is the higher requirement requirement.Its super early strong and not dispersed under water characteristics will be given prominence to, and also will overcome the many shortcomings in water glass solid poor durability and the double quick construction.The degree of mobilization that its requirement is made into grouting can reach more than the 300mm, and degree of mobilization is constant substantially before the gelling, but also time regulation and control between several minutes was by several hours during controlled condensing, so this low basicity is super early coagulates technical indicator that character possessed cement base-material itself and can be described as very harshly, and causes also costliness of cost that existing low alkali early coagulates aluminosulfate cement for this reason.Even so can as grouting base-material special cement, the proportioning slurry that can form can be stablized, good fluidity, do not disperse in the water, the morning present domestic difficulty still strong, high-strength, good endurance find.
Summary of the invention
The object of the present invention is to provide a kind of new variety of modified low-alkalinity sulphoaluminate cement.It should be with the low basicity of excellence, early strong, the high-strength and presetting period is regulated easyly, reliable, impels the proportioning of slurry of formation easy and simple to handle, inexpensive, and can continue in good flowability of formation and the water not dispersed.
The composite type modified cement that basic design of the present invention is based upon aluminosulfate cement and the formation of silicate cement intersection proportioning has on the theoretical basis of special modified effect.By being base-material with the sulfoaluminate clinker, Portland clinker is that properties-correcting agent carries out the quadrature proportioning test, in conjunction with X-ray diffraction analysis (XKD) to proportioning sample piece, differential thermal thermogravimetric analysis (DTA/TG), scanning electron microscope analysis (SEM), and through each control group detection, contrast, conclude, found the proportioning rule of carrying out modification with Portland clinker, and make the modification conditioning agent in conjunction with gypsum, add and join blended material and be prepared into modified low-alkalinity sulphoaluminate cement, be the preparation cement-based grout material vocal imitation skill stable performance that can obtain at present, modified low-alkalinity sulphoaluminate cement with low cost.
Below in conjunction with the embodiment that provides, further specify and the objective of the invention is how to realize.
Embodiment
Below given be the embodiment of one group of modified low-alkalinity sulphoaluminate cement.

To take sulphoaluminate cement clinker and Portland clinker among the above embodiment be base stock, mainly be considered in the cement production process convenient and calculate in simple and direct.In fact key of the present invention is to have utilized sulplo-aluminate and the silicate cement mutual modification promoter action in the hydration reaction in mixing match, formed low alkali, early coagulated, early strong, high-strength and mobile, and not dispersed in the water.So, take cement clinker or cement, as long as the proportioning of its effective ingredient is grasped accurately, the effect that is reached should be consistent.So, only enumerated among the present invention with sulphoaluminate cement clinker make base-material, Portland clinker is the basic mix proportion scheme of properties-correcting agent, the variation of other raw material, engineering technical personnel to cement industry, be understood that, also be not difficult to operate, only adjust the supporting modification conditioning agent gypsum and the proportioning of blended material and get final product, this no longer superfluous chatting.
Gypsum among the embodiment is to be that basic raw material calculates its effective composition with the natural anhydrite.Also can take dihydrate gypsum, dehydrated phosphogypsum or fluorgypsum to substitute, also can use wherein two or more mixture replacing, but the corresponding weight percent among the embodiment is meant the effective ingredient equivalent scaled value that equal natural anhydrite calculates when calculating.
Blended material is the common terminology in the cement manufacturing industry, and tangible implication is meant effective and harmless stopping composition.Being added in of it does not influence under the cement technology performance and can reduce production costs widely, and do not influence the effect of use, these blended materials can be adopting iron ore tailings or slag, flyash, Wingdale or coal gangue, can be wherein a kind of or the mixture after pulverizing, grind, sieving more than two kinds and two kinds.
The compound low-alkalinity sulphoaluminate cement that forms by above proportioning has good low alkali, early strong, fast hard performance, surface property is better than common low-alkalinity sulphoaluminate cement, the time was longer than common low alkali aluminosulfate cement slightly when it condensed, but has good performance-adjustable, be beneficial to suiting measures to local conditions in the construction process, owing in the proportioning in large quantities the application mix material reduced cost, the quality of infrastructural project is used and effectively improved to the amount in antiseepage, the stoppage engineering of helping.
