Nano‐SiO2 (NS), due to its prominent nucleation and pozzolanic effects, holds the promise to effectively enhance the tensile and compressive properties of high‐strength strain‐hardening cementitious composite (HS‐SHCC) at both early age (1d, 3d) and normal curing age (28d). The influence of nano‐SiO2 (NS) on the hydration, microstructure and mechanical properties of HS‐SHCC with different dosages...
The Ramsey number is of vital importance in Ramsey's theorem. This paper proposed a novel methodology for constructing Ramsey graphs about R(3, 10), which uses Artificial Bee Colony optimization(ABC) to raise the lower bound of Ramsey number R(3, 10). The r(3, 10)-graph contains two limitations, that is, neither complete graphs of order 3 nor independent sets of order 10. To resolve these limitations,...
