Description
Technical field
The present invention relates to building material field, particularly a kind of adulterant and preparation method thereof and concrete prepared therefrom.
Background technology
At present, the adulterant for building material industry is mainly slag, flyash equal industrial residue.In recent years China's capital construction develop the sharply expansion having driven cement and concrete industry rapidly, flyash, slag etc. is caused originally to become very well sold and in short supply as the adulterant of waste residue utilization, wherein, the excellent use properties of blast-furnace slag causes its price to rise steadily, and once even exceedes grog price.Visible exploitation adulterant new variety day by day become the task of top priority of building trade research.
Basalt (basalt) belongs to basic volcanic rocks, its compact structure, and proportion is all heavier than general grouan, limestone, sandstone, shale.Basalt is a kind of transportation building stone of high-quality, particularly building build highway, one of material of construction best in the engineering such as railway, port and pier, airfield runway, it has the features such as ultimate compression strength is large, crush values is low, wear-resisting, water-intake rate is low, electroconductibility is weak, erosion resistance is strong, asphalt adhesion is strong, and international endorsement is the foundation stone that Development of Railway is transported and transport by road is best.
At present prepared by the research of cement to basalt more, such as:
Luo Bingyin, Wei Guang, Sha Yan and, " making cement mixture with basalt " (cement technology, 1999 (2): 49-50) of Wu Liya
" basalt makes the experimental study that cement produced by blended material " (Sichuan cement, the 1997.1:33-35) of Wu Wujun
" basalt does the experimental study of cement raw material " (Luoyang higher junior college journal, 2003,13 (3): 7-10) that weekly assembly becomes
Xie Shasha. " research of cement-pozzolan matter gelling system hydration mechanism " ([master thesis], Wuhan: Changjiang Academy of sciences, 2010)
Chen Changqing, Chen Yanan, Mu Shanbin. " basaltic hydration activity and the experimental study as cement mixture thereof " (state's outdoor building materials science and technology, 2003.24 (1): 9-10)
How above research prepares cement to basalt if all mainly concentrating on, and prepared by adulterant for use basalt, and concrete prepared by the adulterant to be made up of basalt, then rarely have research, be mainly divided in two to the application of basalt in concrete both at home and abroad at present: on the one hand due to its there is wear-resisting, resistance to compression, the feature such as crush values is low, water-intake rate is low, electroconductibility is weak, asphalt adhesive ability is strong and erosion resistance is strong and as preparing the concrete coarse aggregate of road bitumen; Another aspect is by basalt building stones after 1450 DEG C ~ 1500 DEG C meltings, and by the continuous fibre of platinum rhodium bushing high speed pulling, mix in concrete and improve its performance, but its cost is higher, basalt fibre per ton is about 20000 yuan.
Chinese patent CN102674782B provides one and " makees adulterant with basalt micro mist-slag micropowder-limestone powder and prepare concrete method ", basalt, slag, Wingdale separate compiling are micro mist by it, remix is evenly as adulterant, in the concrete process of preparation, then add water reducer and exciting agent in mixing water.The micro mist standard of this technical scheme to basalt, slag, Wingdale has different requirement, therefore manufacturing processed more complicated, and needs to add the ancillary components such as exciting agent more separately preparing in Concrete, therefore also makes to prepare concrete process more loaded down with trivial details.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of adulterant and preparation method thereof, to reduce or to avoid problem noted earlier.
For solving the problems of the technologies described above, the present invention proposes a kind of adulterant, it is mixed by after following raw materials according in mass ratio grinds: basalt 30-70%, sandstone 0-30%, flyash or coal gangue 18-22%, gypsum 3-6% through calcining, Portland clinker or sulphoaluminate cement clinker 5-10%, manganese mud or phosphorus-slag-powder 0-15%.
