<p>The present invention relates to a milk grouting material for bored pile construction, and more specifically, to a milk grouting material for bored pile construction, which can implement performance higher than a type one cement by using petroleum coke desulfurization plaster, cement, and an expansion agent to blast furnace slag powder to replace the type one cement, prevents loss of a milk solution caused by underground water existed between a perforated hole and a bored pile highly improving end bearing capacity and skin friction force of the bored pile compared to an existing cement milk solution. The milk grouting material for bored pile construction comprises: 5-200 parts by weight of petroleum coke desulfurization plaster having more than or equal to 50 wt% calcium oxide and more than or equal to 15 wt% of sulfate oxide; and 50-300 parts by weight of mixing water.</p> |
