Experimental Study on Mechanical Properties of New Self-Compacting Concrete for Strengthening Engineering

Abstract:

Base on the practical experience of reinforcing engineering and the application of new type of cement based grouting material in recent years, a new type of cement-based concrete for strengthening engineering with high-bonding, low-shrinking, self-compacted was developed in this paper. Fast-speed strengthening and repairing of structures can be realized by combining this new strengthening material with the traditional method of increasing section area for strengthening, and by the adoption of the technology of perfusion pumped on-site. This new strengthening concrete can be applied to both reinforced concrete structures strengthening and masonry structures strengthening. Compared with the traditional strengthening method of increasing section area, due to smaller section needed, the construction speed is quicker, and the quality can be more easily guaranteed. Therefore, this new type of material possesses a wide application prospect. And a series of experimental researches on the mechanical properties of this new strengthening concrete is conducted in this paper.
