EN 206-1

UNIT OF MEASURE

S.I.


CEMENTITIOUS MATERIALS

measured by mass
tolerance ± 3%


MIXING WATER

measured by mass or volume
total water: tolerance ± 3%
water shall be determinated taking due account of the aggregatees moisture


AGGREGATE

measured by mass
tolerance ± 3%
light aggregate canbe measured by mass or volume


CHEMICAL ADMIXTURE

measured by mass or volume
if chemical admixture mass ≤ 5% of cement mass, tolerance ± 5% max 50 g/kg of concrete
if chemical admixture quantity < 2 g/kg it must be dispersed in mixing water
if chemical admixture quantity > 3 l/m3 its water content must be considered for water/cement ratio


BATCHING PLANT / MEASURING EQUIPMENT

n/a


AIR CONTENT

max + 4% of specified value


CONSISTENCY

 

slump/tolerance

slump < 40: ± 10
≥ 50 slump ≤ 90: ± 20
slump ≥ 100: ± 30


DISCHARGE

the temperature of fresh concrete shall not be less than 5°C


MIXERS AND AGITATORS

the mixers shall be capable of achieving a uniform distribution of the constituent
materials, and a uniform consistence of the concrete within the mixing time and at the mixing capacity
truck mixers and agitating equipment shall be so equipped as to enable the concrete
to be delivered in a homogeneous state
