describes pumps for transporting and placing concrete. Rigid and flexible pipelines are discussed and couplings and other accessories described. Recommendations for proportioning pumpable concrete suggest optimum gradation of aggregates; outline water‚ cement‚ and admixture requirements; and emphasize the need for evaluation of trial mixes for pumpability. The importance of saturating lightweight aggregates is stressed. Suggestions are given for layout of lines; for maintaining uniform delivery rate‚ as

Stroke What is stroke? A stroke is a serious medical condition that occurs when the blood supply to part of the brain is cut off. Strokes are a medical emergency and prompt treatment is essential because the sooner a person receives treatment for a stroke‚ the less damage is likely to happen. Ischemic strokes Ischaemic strokes‚ the most common type of stroke‚ occur when blood clots block the flow of blood to the brain. Blood clots typically form in areas where the arteries have been narrowed
