BS EN 15368-2008 pdf download.Hydraulic binder for non-structural applications: definition, specifications and conformity criteria.
hydraulic binder for non-structural applications
factory made finely ground inorganic material which, when mixed with water and fine aggregates. produces a mortar with workability, adhesion and strength properties that make it suitable for use in rendering, plastering and masonry work. Hardening of a Hydraulic binder for non-structural applications is mainly due to the hydration of calcium silicates. However, other chemical compounds – i.e. aluminates – also take part in the setting and early stiffening processes thus generating a hardened mass that retains its strength and soundness properties even under water. Although it consists of finely ground granules of different materials, the Hydraulic binder for non-structural applications has a statistically homogeneous composition.
3.2
additives
constituents which are added to improve the manufacture or the properties of the Hydraulic binder for non- structural applications. e.g. grinding agents, air-entraining agents, etc.
3.3
allowable probability of acceptance CR
for a given sampling plan, the allowed probability of acceptance of Hydraulic binder for non-structural applications with a characteristic value outside the specified characteristic value
3.4
sampling plan
specific plan which states the (statistical) sample size(s) to be used, the percentile Pk and the allowable probability of acceptance CR
3.5
characteristic value
value of a required property outside which lies a specified percentage, the percentile P8. of all the values of the population
3.6
specified characteristic value
characteristic value of mechanical, physical or chemical property which in the case of an upper limit is not to be exceeded or in the case of a lower limit is, as a minimum, to be reached
3.7
single result limit value
value of mechanical, physical or chemical property which – for/any single test result – in the case of an upper limit is not to be exceeded or in the case of a lower limit is, as a minimum, to be reached.
3.8
spot sample
sample taken at the same time and from one and the same place, relating to the intended tests. It can be obtained by combining one or more immediately consecutive increments (see EN 196-7).
Hydraulic binder for non-structural applications is designed by the term HB. There are two strength classes of Hydraulic binder for non-structural applications: 1,5 and 3.
5 Requirements
5.1 General
The physical, mechanical and chemical properties of Hydraulic binder for non-structural applications shall be measured by test methods described in EN 413-2 and the relevant parts of EN 196. These European Standards give alternative test methods for some properties but in the event of a dispute only the reference methods shall be used. Where allowed in the relevant part of EN 196, different methods may be used provided they give correlated and equivalent values to those obtained using the reference method.
The CEN standard sand used to make the mortars for the tests required by 5.3.4 and 5.3.5 shall fulfil the requirements of EN 196-1.
All requirements are specified as characteristic values, They serve to define the performance level and classification of the Hydraulic binder for non-structural applications.
5.2 Constituents and composition
Hydraulic binder for non-structural applications shall comprise Portland cement clinker, inorganic constituents and where appropriate additive(s) as given in Table 1. Calcium sulphate is added in small quantities to the other constituents of Hydraulic binder for non-structural applications during its manufacture to control setting.
The inorganic constituents of Hydraulic binder for non-structural applications conforming to this standard shall be materials selected from:
— Portland cement clinker meeting the requirements of EN 197-1;
— Common cement specified by EN 197-1:
— Constituents specified by EN 197-1;
— Calcium sulphate added upon grinding in such an amount that the setting process can be controlled;
— Hydrated and/or hydraulic building limes conforming to EN 459-1;
— Additives.
The production cycle and the control system shall ensure that the composition of the HB is in compliance with the limits set forth in Table 1 below.BS EN 15368-2008 pdf download.
