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 microballon is 10-30kg.
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 microballon prepare after mixing.
In the present invention, to the shapes and sizes of stone, sand, phenolic fibre and microballon, there is no particular limitation, but is
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 particle diameter
The river sand of 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 circle
Shape and a diameter of 0.8-2.5mm；The particle diameter of described microballon 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 microballon are mixed, to batch mixing
Order there is no particular limitation, but in order to make concrete have more excellent shock resistance, it is preferable that the order of batch mixing is
First cement, sand, stone, water, water reducer and phenolic fibre are mixed, add microballon the most again and mix.
The present invention on the basis of cement, sand, stone, water and water reducer by adding phenolic fibre and microballon, thus
Enhancing the shock resistance of concrete, wherein phenolic fibre and microballon 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.
