Extracted from text ... TWO NEW PRODUCTS for optimum concrete production developed by Chryso in France are now available from Chryso South Africa. The first, Chrysofibre S50, is a second-generation synthetic macro-fibre that improves the characteristics of hardened concrete after cracking has occurred: the presence of the fibre prevents the cracks from opening. Chrysofibre S50 consists of polypropylene and polyethylene fibres. With an elasticity of 5 GPA and tensile strength of 600 MPa, Chryso's new macro-fibre can replace metallic fibres and can be used in much smaller quantities. 'In fact, Chrysofibre S50 can be applied at just one-seventh of the dosage for metallic fibres, ' ..
