These are many factors that can influence the properties of alkali-activated slag cementitious material, such as the modulus and content of water glass, water-cement ratio, curing conditions, and so forth. The rules that how these factors affect setting time and strength of the material are systematically discussed in the paper. It is found that the setting time of the material depends on the concentration of alkaline ions in solution; The material will have the best strength when the modulus and content of water glass are 1.4 and 8%, respectively. The curing temperature increase will be helpful to compressive strength increase.

Strengthening Method

Alkali-activated slag cementitious material (AASCM), a high-temperature resistant inorganic adhesive, is presented in this paper. The components of AASCM were optimized for favorable mechanical properties. A FRP-to-concrete bond test to account for the influence of FRP and adhesive types was performed on thirty-three specimens. The results show that after the double shear tests, the interfacial shear strengths and reinforcing effects of AASCM are comparable to that of epoxy adhesive, and this strengthening method of strengthening concrete structures with CFRP sheets bonded with AASCM is feasible.
