CP65 but who have little or no experience of high strength concrete (HSC). The guide is intended to provide safe design guidance, based on the best available information, especially in the areas not adequately covered by CP65. In this respect, the guidance and recommendations in the Concrete Society Technical Report 49 are very relevant
Floor screeds. A floor screed is usually a cementitious material made from a 1:3 or 1:4.5 ratio of cement to sharp sand. It may be applied onto either a solid in-situ concrete ground floor slab or onto a precast concrete floor unit. There are many proprietary screeds on the market and information about these can be obtained from the manufacturer.
labour force our concrete is designed and produced to meet and exceed the specific requirements and to deliver high performance, durability, longevity and value throughout its service life. Sometimes referred to as visual concrete, fair faced finish or special finish, architectural concrete is designed and required to have a more visually pleasing
