Son, water, water reducer, phenolic fibre and phosphorous slag micropowder composition；
Wherein, relative to the stone of 1000kg, the consumption of described cement is 500-700kg, and the consumption of sand is 350-
450kg, the consumption of described water is 160-280kg, the consumption of described water reducer is 3-6kg, and the consumption of described phenolic fibre is 8-
22kg, the consumption of described phosphorous slag micropowder is 55-65kg.
The preparation method of the concrete of the shock resistance with excellence of the present invention is the water by said components and content
Mud, sand, stone, water, water reducer, phenolic fibre and phosphorous slag micropowder prepare after mixing.
In the present invention, to the shapes and sizes of stone, sand, phenolic fibre and phosphorous slag micropowder, there is no particular limitation,
But in order to improve the shock resistance of the concrete of preparation, it is preferable that the particle diameter of described stone is 8-22mm；Described sand is grain
The river sand of footpath 0.4-0.6mm；The a length of 8-10mm of described phenolic fibre, the cross section of the length direction of described phenolic fibre is
Circular and a diameter of 0.8-2.5mm；The particle diameter of described phosphorous slag micropowder is 0.2-0.5mm.
In the present invention, described cement can make commercially available any portland cement, so that the coagulation of preparation
Soil has more excellent shock resistance, it is preferable that described cement be numbered 52.5 portland cement.
In the present invention, described water reducer can be naphthalene series high-efficiency water-reducing agent, Ppolynuclear aromatic salt water reducer or water-soluble
Property resin Sulfonates water reducer, in order to reduce cost, it is preferable that described water reducer can be naphthalene series high-efficiency water-reducing agent.
In the present invention, to the temperature mixed, there is no particular limitation, in order to make concrete have more excellent shock resistance
Performance, it is preferable that the temperature of described mixing is 20-30 DEG C.
In the present invention, when cement, sand, stone, water, water reducer, phenolic fibre and phosphorous slag micropowder are mixed, right
There is no particular limitation for the order of batch mixing, but in order to make concrete have more excellent shock resistance, it is preferable that batch mixing suitable
Sequence, for first cement, sand, stone, water, water reducer and phenolic fibre to be mixed, is added phosphorous slag micropowder the most again and is mixed
Close.
The present invention on the basis of cement, sand, stone, water and water reducer by adding phenolic fibre and phosphorous slag micropowder,
Thus enhance the shock resistance of concrete, wherein phenolic fibre and phosphorous slag micropowder are all the raw materials being easy to get.
Heretofore described shock resistance is to be embodied by comprcssive strength parameter and cleavage strength parameter, resistance to compression
Intensive parameter and the highest then shock resistance of cleavage strength parameter are the most excellent.The comprcssive strength of the concrete of the present invention is 28.63
～48.63MPa；Cleavage strength is 2.86～4.02MPa.
Other features and advantages of the present invention will be described in detail in detailed description of the invention part subsequently.
