Concrete is made by mixing cement, supplementary cementitious materials, water, fine aggregate (sand), coarse aggregate (gravel or crushed stone) with or without admixtures, reinforcement, fibres or pigments.oncrete is easily and readily prepared and fabricated in all sorts of conceivable shapes and structural systems. Its great simplicity lies in the fact that its constituents are ubiquitous and are readily available almost anywhere in the world 1.
Debulking is the reduction of as much of the bulk (volume) of a tumour as possible. It is usually achieved by surgical removal. It is also known as cytoreduction or cytoreductive surgery (CRS); cytoreduction refers to reducing the number of tumor cells.
Often, patients with ovarian cancer are initially treated with surgery aimed at debulking (decreasing the size of) the tumor. This type of surgery, in which the goal is to remove the greatest volume of cancer cells possible, is also called âcytoreductiveâ surgery.
