Determination of optimal process for microwave curing of concrete
TL;DR: In this paper, the authors used feedback temperature control to identify the optimal power history of a continuously varying curve for precasting and repair of concrete with low-cost microwave generators, where the power curve is approximated with discrete power levels.
Effect of rubber modifier on interlaminar fracture toughness of CFRP-concrete interface
TL;DR: In this article, the influence of reactive rubber modifier added in the adhesive on interlaminar fracture resistance between the CFRP strip and concrete was investigated, which showed significant improvements with 10 and 20% rubber modifier contents.
A novel distributed optical crack sensor for concrete structures
TL;DR: In this paper, a novel optical fiber sensor was developed for the detection of cracks and the subsequent monitoring of their openings, where no apriori knowledge of crack location is required, and a small number of fibers can be employed to detect and monitor a large number of cracks.

TL;DR: In this article, the authors developed a kind of waterproof ECC, with 28-day compressive strength around 35-MPa, ultimate tensile strain over 4%, a water contact angle larger than 110 degree, 28day drying shrinkage about 2/3 the value of the typical ECC (M45), a water absorption rate around 5-×-10−5mm/s1/2 and a water permeability coefficient about 8.
Fracture Mechanics Approach for Failure of Concrete Shear Key. II: Verification
TL;DR: In this paper, a mechanical model for the failure of plain or fiber-reinforced concrete shear key joints through the comparison of the model's prediction with both experimental measurements and finite element method (FEM) analysis results is presented.
