Abstract: The present invention relates to a foundation reinforcing apparatus using a bracing-type supporting structure and a lateral prestressing device and a foundation reinforcing method using the same, wherein, in the foundation reinforcement used for remodeling construction that requires an extension of a building such as an apartment, the foundation reinforcing apparatus introduces lateral pre-stressing force into a bracing-type supporting structure to introduce a preloading load to a new pile of a new footing by using an upper supporting plate, which is connected to an existing vertical part and an existing slab, as a reaction bed and allows the new pile to share a load applied before and after the extension of the building so that reinforcement efficiency is increased, and thus construction is performed economically.

Abstract: Provided are a textile reinforced cement composite for suppressing occurrence of slipping and a crack and a manufacturing method thereof. The textile reinforced cement composite for suppressing occurrence of slipping and a crack can suppress slipping between a textile grid reinforcement and a cement composite by using an angulated filling material mixed therewith when a textile reinforced cement composite having a textile grid reinforcement embedded in a cement composite is manufactured, suppress occurrence of a crack of the cement composite, suppress occurrence of a crack of the cement composite due to a fiber bridging reaction by using organic fiber mixed therewith, induce distribution of fine cracks, suppress degradation of fluidity of the cement composite caused by mixing of the angulated filling material by using a spherical binder and a chemical admixture added thereto, and suppress slipping between the textile grid reinforcement and the cement composite by using a fine powder binder having a predetermined particle size and mixed therewith.
