The energy of concrete is measured in ห้างหุ้นส่วนจำกัดสหคอนกรีตอัดแรง pounds for every square inch or kilograms for every square centimetre of pressure needed to crush a sample of the provided age or hardness. Concrete’s toughness is influenced by environmental factors, Primarily temperature and dampness. Whether it is allowed to dry prematurely, it may possibly knowledge unequal tensile stresses that in an imperfectly hardened condition can not be resisted.
