dealt with materials issues such as the use of portland cement replacement materials and recycling of concrete removed from existing structures. However, any discussion of the sustainability of the concrete industry must consider industry concerns much broader than those of "greenness" of a given technology.
Total knee replacement is one of the most commonly performed joint replacement surgeries. Total knee arthroplasty (TKA) is a surgical procedure to replace diseased ends of the knee joint with prosthetic materials. Traditionally knee replacement surgery has been performed used cemented prosthesis.
Physical and chemical material properties were characterized for nine different replacement candidates. A total of over 60 mortar mixes and 20 concrete mixes were prepared for evaluation of workability, structural adequacy, and durability.
Fresh Concrete: In general, supplementary cementitious materials improve the consistency and workability of fresh concrete because an additional volume of fines is added to the mixture. Concrete with silica fume is typically used at low water contents with high range water reducing admixtures and these mixtures tend to be cohesive and stickier

In short, sidewalk repair requires less labor, time, and materials than replacement. Replacing entire concrete sidewalk slabs means hiring a crew to break it up, remove it, set the foundation, and repour the concrete. This means you get stuck paying for quite a bit of material and hours of labor across a team of professionals.
