771 series) block strengths in BS5628 were changed to reflect this so that, for example, an old /mm² is now /mm². For designs to BS5628, the characteristic compressive strength of masonry, fk, should be obtained from Tables 2a 2h (based on mortar strength and size of masonry unit). Given below are values interpolated from BS5628 Table 2 which are relevant to .
The required crushing strength of a concrete pipe can be calculated using the following equation. Wt > (We x Fs) / Fm. Where: Wt = required crushing load (kn/m), (Fn=Wt) We = Total applied load on the pipe (kn/m) Fs = Factor of safety ( MINIMUM) Fm = the bedding factor. Crushing load (Wt) as stated in 6: 2004 "Perforated Pipes" Table. NOTE: The minimum crushing load .
ultimate strength. • The strain at which crushing of concrete takes place is for highstrength concretes to more than for lowstrength concretes. • For design, a conservative value of is considered as the ultimate strain, for all concretes except very high strength .

H+H's Celcon Blocks High Strength Grade (/mm 2 – identified with a black stripe on the block) and Super Strength Grade (/mm 2 – identified with a red stripe on the block) are ideal where higher compressive strengths are required such as in the foundations and lower storeys of three storey buildings, piers under high vertical loads and in multistorey buildings.
· An analysis of the abrasive wear of concrete floors has revealed that highintensity crushing is the chief mechanism of deterioration, and hence the concrete crushing strength is the relevant parameter determining wear resistance. 248 Generally, the abrasion resistance of the coarse aggregate component is not related to the wear resistance of the concrete; rather, the .
