e) Although strong under compressive stress, concrete is far weaker under tensile stress. Explain briefly why this is so. f) Recent experiments have involved adding fine particles of silica and fly ash from coal-fired power plants to concrete mixtures. This increased the strength of the concrete in compression by almost five times. Suggest why this happens. g) Concrete can be strengthened by prestressing. Explain briefly what this involves and why it works.
