Agent or water-soluble resin Sulfonates water reducer, in order to reduce cost, it is preferable that described water reducer is permissible
It it is naphthalene series high-efficiency water-reducing agent.
In the present invention, to the temperature mixed, there is no particular limitation, more excellent in order to make concrete have
Shock resistance, it is preferable that the temperature of described mixing is 20-30 DEG C.
In the present invention, by cement, slag, modified polypropene, water, water reducer, phenolic fibre and phosphorus
When slag micropowder mixes, to the order of batch mixing, 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 be first by cement, slag, modified polypropene,
Water, water reducer and phenolic fibre mix, and add phosphorous slag micropowder the most again and mix.
The present invention on the basis of cement, slag, modified polypropene, water and water reducer by add phenolic aldehyde
Fiber and phosphorous slag micropowder, thus enhance the shock resistance of concrete, wherein phenolic fibre and phosphorus slag are micro-
Powder is all the raw material being easy to get.
Heretofore described shock resistance is to be carried out by comprcssive strength parameter and cleavage strength parameter
Embodying, comprcssive strength parameter and the highest then shock resistance of cleavage strength parameter are the most excellent.The present invention's is mixed
