Different spinning methods are available in making yarns, including ring-spun, rotor-spun, twistless, wrap-spun and core-spun yarns.. Ring-spun yarns: This is the most widely used method of staple-fibre yarn production. The fibres are twisted around each other to give strength to the yarn. • Rotor-spun yarns: These are similar to ring-spun yarns and usually made from short staple fibres.
The developed ultra-high performance spun concrete (UHPSC) is based on a further development of the mix design for high-performance spun concretes up to C100/115, which have already been approved by building authorities for the production of poles, columns, and beams [9].
