present in a concrete mixture, then the concrete can be prone to segregation and higher bleeding. In contrast, a mixture with excessive fine material can be sticky and difficult to finish. For example, ACI 211.1, Table 6.3.6, recommends that if fine aggregates have a high proportion of fine material (manifested by a low fineness modulus),
Concrete is a mixture of cement, sand (fine aggregate), small stone or gravel (coarse aggregate) and water. It has many applications, from fence posts to motorway bases and, because of this, there are many different concrete mix ratios that the constituents can be mixed to with each resulting in a different strength of concrete.
CIP 17 - Flowable Fill Materials WHAT is Flowable Fill? Flowable fill is a self-compacting low strength material with a flowable consistency that is used as an economi-cal fill or backfill material as an alternative to compacted granular fill. Flowable fill is not concrete nor it is used to replace concrete. Terminology used by ACI Committee

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.
