The toughness of concrete is ห้างหุ้นส่วนจำกัดสหคอนกรีตอัดแรง calculated in lbs . for each sq. inch or kilograms for every square centimetre of power required to crush a sample of a provided age or hardness. Concrete’s energy is afflicted by environmental elements, Specially temperature and humidity. If it is allowed to dry prematurely, it might working experience unequal tensile stresses that in an imperfectly hardened point out can not be resisted.
