BS 8500 - Concrete Centre

BS 8500 is the British Standard for specifying and producing concrete. It is the complementary British Standard to BS EN 206. BS 8500 is split into two parts. Part 1 covers specifi ion and gives guidance to the specifier. Part 2 covers the constituent materials in concrete and contains the information required by the concrete producer. BS 8500-1:2015 A2:2019


Variation and probability of concrete strength finding standard deviation and k values to calculate the margin. b. Characteristic strength Probability and statistics have been widely adopted in engineering to describe structure failure and material properties. In the old practice, concrete strength is specified using "minimum strength".

Cements for use in concrete are factory-produced materials produced by either inter-grinding or blending their constituents at the cement works. They conform primarily to the British/European Standard BS EN 197-1. Some cements, such as sulfate-resisting Portland cement SRPC are however still covered by residual British Standards.

Because of the variability of concrete strengths 12 the mix must be designed to have a considerably higher mean strength than the strength specified. The method of specifying concrete by its minimum strength has been replaced in British Standards and Codes of Practice such as BS 5328 13 and BS 8110 14 by a ‘characteristic strength’.
