A process for producing insulating foam, wherein certain especially small inorganic minerals such as silica fume are directly integrated into bubble fluid to better mechanically strengthen bubbles formed and thus allow the formation of smaller bubbles to be reformed by mechanical means. In this process where these same bubbles are now in some part composed of inorganic solids. A process whereby these minerals are maintained as to their median size and dispersion within the bubble fluid by the following; rotor stator mixing and or a recirculating pump, the inclusion within exotherming calcium-chloride salt, the use of other physical exciters such as hydrogen-peroxide, and by straining out outliers of unwanted size or form. The above mentioned mechanical means is a progressive reforming of bubbles and actualized by a glass bead chamber, a second stage consisting of two screened discs, separated from each other and located at the end of the glass bead chamber, and a third stage chamber presenting itself with a considerably enlarged screen area and having considerably finer meshes than the second stage. This process in its execution results in stronger, smaller and denser bubbles; whereupon when complete hydration has occurred, leaves the smaller solids in their placement within the now open cell structure, and in combination with applied cement from a separate process line, the cured cement foam has a significant registered improvement of insulating qualities as measured by certified R-value tests. 1.

The present invention relates to an ultra-rapid hardening cement concrete composition with improved durability, and a pavement maintenance and repair method using the same. According to the present invention, the ultra-rapid hardening cement concrete composition comprises: 5 to 45 weight percent of an ultra-rapid hardening coupling agent; 15 to 75 weight percent of fine aggregates; 15 to 70 weight percent of coarse aggregates; 1 to 25 weight percent of a performance modifier; and 4 to 30 weight percent of water. The ultra-rapid hardening agent comprises: 5 to 79 weight percent of earl-strength Portland cement; 10 to 50 weight percent of calcium or magnesium sulfonate aluminate; 2 to 35 weight percent of blast furnace slag powder with a particle size of 3,000 to 9,000 cm^2/g; 1 to 30 weight percent of tricalcium aluminate; 1 to 30 weight percent of peat or turf; 1 to 20 weight percent of gypsum; 1 to 10 weight percent of kaolin; 1 to 10 weight percent of nitric kalmite; 1 to 10 weight percent of lithium carbonate; 1 to 10 weight percent of clinoptilolite; 0.5 to 5 weight percent of a deforming agent; and 0.5 to 5 weight percent of a water reducing agent. According to the present invention, the ultra-rapid hardening cement concrete composition promotes the densification of an inner tissue to form dense concrete, thereby providing an effect of improving strength and durability, in particular, waterproofness and corrosion of the concrete. Moreover, wear resistance is excellent to improve scaling resistance, thereby providing an effect of preventing deterioration of a surface of pavement. Moreover, provided are effects of preventing surface crack and expansion breakage caused by drying shrinkage, and providing a self-crack curing effect, which absorbs water and discharges the water again to fill a crack while existing inside the cured concrete in a reduced volume state.

The present invention relates to a combined type slope reinforcing method using high performance shotcrete and a reinforcing member comprising the steps of: producing normal concrete with compression strength of 21-30 MPa in a batcher plant and transferring the normal concrete to a field; increasing the fluidity of the normal concrete by introducing 20-40% of bubbles, based on the volume of the normal concrete, to the normal concrete; forming normal strength shotcrete by mixing the normal concrete with low grade mixing material, which is either of fly ash and slag fine powder or the mixture of the fly ash and the slag fine powder; forming high performance shotcrete by mixing the normal concrete with high grade mixing material which is either of silica fume and metakaolin or the mixture of the silica fume and the metakaolin; forming color shotcrete by mixing the normal concrete with a coloring agent such as iron oxide or carbon black; and successively forming an inner layer part, an outer layer part, and a surface layer part on a slope. Therefore, the present invention reduces construction costs and secures high strength and high durability of the slope. Moreover, maintenance for the slope can be easily performed.
