Description
Technical field
The invention belongs to building material technical field, relate to a kind of preparation method of ultra-high strength mortar.
Background technology
The building of some engineering constructions, particularly erosion environment, as the ground of buildingss such as chemical plant, food processing plant, freezer, Heavy Machines Plant and the construction of harbour and ocean platform, radioactive waste storage vessel etc., need the ultra-high strength mortar that great amount of cost is lower, can prepare at the construction field (site).
The preparation of existing domestic and international ultra-high strength mortar, be to adopt levigate portland cement, the silicon ash (or slag, flyash etc.) of ultra-fine grain, meticulous quartz sand (or other high-quality fine aggregate mostly, as Stainless Steel Powder), composition such as water and superplasticizer, during moulding by applying form removal after room temperature leaves standstill 1 day behind certain pressure, use 80 ℃ or above hot water bath maintenance room temperature maintenance several days after a day, again 1 day postcooling of high temperature (about 200 ℃) dry heating curing to the room temperature maintenance to the length of time, ultimate compression strength reaches more than 150 MPas.Though the mortar intensity height of this technology preparation, cost height, complex process are not suitable for engineering and use, and only limit to make the prefabrications such as mould of some instrument, thermoplastic resin at present.
The preparation of a kind of ultra-high strength mortar of document " Tensile properties of fibre-reforced very high strength DSPmortar (Magzine of Concrete Research; 2000; 52; No.2; Apr.; 101～108) " narration improves on technology, and its material is 400～450m by specific surface area
2The white portland cement of/kg, silicon ash, powdery superplasticizer, meticulous quartz sand, water are formed, stir the back 75 hertz of shaking table vibratory compactions, 80 ℃ of hot water bath maintenances are 24 hours after the form removal in 24 hours, again in testing laboratory's condition maintenance to the length of time, making the minimum ultimate compression strength of 75mm * 150mm right cylinder is 150 MPas.This method cost is still high, technology is complicated, still is difficult at the construction field (site) realize; Because being 62.5 cement specific surface area, domestic best label also can only reach 380.6m
2/ kg, the preparation of this mortar also needs import cement.
Because prior art prepares the difficulty of ultra-high strength mortar at the construction field (site), strength on concrete material at present for building is low, degree of compactness is little, and being used for some needs the engineering construction of the strong high compact material of superelevation unsatisfactory.
Summary of the invention
Purpose of the present invention is to provide a kind of preparation method of ultra-high strength mortar, and this mortar is with low cost, is convenient to the working-yard preparation, and its intensity can reach 140-150 MPa (MPa), engineering construction that can the strong high compact material of dealing with various requirements superelevation.
A kind of preparation method of ultra-high strength mortar, it is characterized in that raw material is cement, silicon ash, silica sand, quartz sand, defoamer, water and water reducer, the mass percent of its each component is: cement 35%～50%, silicon ash 5%～15%, silica sand 25%～35%, quartz sand 3%～10%, defoamer 0.1%～0.2%, water 7%～14%, water reducer are 1.5%～4.5% of cement and silicon ash (being gelling material) quality sum, and the each component total amount satisfies 100%;
In the above-mentioned materials, cement is the silicate cement of label 62.5,62.5R, 52.5,52.5R, and the fineness of silica sand is 20～40 orders, and the fineness of quartz sand is 100～200 orders, defoamer is tricresyl phosphate tincture ester or SP-202 series water-based defoamer, and water reducer is a polycarboxylate dehydragent;
Stirring the method for making this ultra-high strength mortar is: adopt the speed change stirrer, in 80 rev/mins～350 rev/mins scopes, promote stirring velocity by shelves, churning time is 10 to 25 minutes, and the mortar that stirs is poured in the mould, places on the shaking table or insert vibrating spear vibration 2～10 minutes; Maintenance process is: when building-site is constructed, adopt existing high performance concrete maintenance process, and the promptly preceding 3 days every 1-2 hour back overlay film that waters, water the back overlay film sooner or later to the length of time every day after 3 days; When making in laboratory, overlay film form removal after about 24 hours is put into the normal-temperature water maintenance to the length of time.
Adopt building trade to make concrete or mortar shaking table or vibrating spear commonly used, 50 hertz of the domestic general employings of vibrational frequency; In building-site construction, when mould more maybe can't be mobile, can adopt the vibrating spear vibration.
Prior art adopts the high temperature maintenance, is in order to promote the volcanic ash effect, thereby improves intensity.Consider the field conduct difficulty, the present invention is conceived to stirring technique, improve and just on macroscopic scale, reached uniform stirring in the past, adopt the speed change stirrer, by the shelves speedup, reach the even of microscopic scale by high-speed stirring, promoted the extent of hydration of cement, thereby improved intensity, realized preparing ultra-high strength mortar with conventional maintenance process maintenance.
Mortar standardized component of the present invention carries out the cubic compressive strength experiment by GB/T 50081-2002 chapter 6, and intensity can reach 140-150Mpa, about 2.4 gram per centimeters of density
3
Except silicate cement, also can adopt other kind cement such as ordinary Portland cement, Portland blast, Portland pozzolana cement, Portland fly ash cement, composite Portland cement of same numeral (being same intensity) to make ultra-high strength mortar of the present invention, the major ingredient of these cement is similarly Portland clinker.When adopting other kind cement, can be with reference to silicate cement mass percent of the present invention, and the volume of other mineral mixing materials in this kind cement, determine the mass percent of this kind cement in mortar.
The present invention has the following advantages:
1, good fluidity, flawless, pore is few and little, the internal structure densification, molded surface is smooth, the intensity height, the value of its strength/density and steel quite, have impermeability and resistance to abrasion preferably.
2, selected materials is mass-produced commercially available prod, and starting material are easy to get.
3, with respect to other ultra-high strength mortars, preparation technology of the present invention is simple and be easy to realize in that engineering construction is on-the-spot, is suitable for through engineering approaches.
