WIPO Patent Application WO/2013/062243
Kind Code:
A1
Abstract:
The present invention relates to a high-performance wet-type shotcrete composition and to a method for constructing a scenic structure using same. More particularly, the present invention relates to a method for constructing a scenic structure having good strength and durability using a wet-type shotcrete composition having high constructability, high strength, and high durability, whereby pumpability is improved due to the presence of a superabundant amount of air before the placement of shotcrete, and whereby shootability is improved due to the presence of a small amount of air after the placement of the shotcrete using the high-performance wet-type shotcrete composition containing silica fumes and an AE agent, wherein the scenic structure provides an excellent scenic view when implemented as a landscape sculpture and due to the natural rock coloring thereof. To this end, the wet-type shotcrete composition comprises 80-85 vol % of the aforementioned shotcrete and 15-20 vol % of air, wherein the aforementioned shotcrete comprises 18-28 wt % of coarse aggregate, 40-50 wt % of fine aggregate, 12-22 wt % of cement, 3-13 wt % of water, 1.4-2.4 wt % of silica fumes, 1.6-2.6 wt % of an expansion agent, 0.01-0.1 wt % of a superplasticizer, and 0.0001-0.01 wt % of an AE agent relative to 100 wt % of the aforementioned shotcrete, and the content of the AE agent is 0.0027-0.005 parts by weight based on 100 parts by weight of the cement.
