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

BATCH TICKET INFORMATION

  • name of the ready-mixed concrete plant
  • serial number of ticket
  • date and time of loading, i.e. time of first contact between cement and water
  • truck number or vehicle identification
  • name of purchaser
  • name and location of the site
  • details or references to specifications, e.g. code number, order number
  • amount of concrete in cubic metros
  • declaration of conformity with reference to the specifications and to EN 206-1
  • name or mark of the certification body if relevant
  • time at which the concrete arrives at the site
  • time of the beginning of unloading
  • time of the end of unloading
  • for designed concrete, the delivery ticket shall give details of the following
  • strength class
  • exposure classes
  • chloride content class
  • consistence class or target value
  • limiting values of concrete composition, if specified
  • type and strength class of cement, if specified
  • type of admixture and addition, if specified
  • special properties, if required
  • maximum nominal upper aggregate size
  • in case of light-weight or heavy-weight concrete: density class or target density
  • for prescribed concrete: details of the composition, e.g. cement content, and, if required, type of admixture either w/c ratio, or consistence in terms of class or target value, maximum nominal upper aggregate size.
