Eurocode 1 - Actions on structures - Part 4: Silos and tanks

1.1 Scope of EN 1991-4 (1) This document provides rules for calculating actions for the structural design of silos and tanks. NOTE 1 Silos are used for the storage of particulate solids. Tanks are used for the storage of liquids. NOTE 2 For limitations on rules for silos given in this document, see 1.3. NOTE 3 For limitations on rules for tanks given in this document, see 1.4. (2) This document includes some provisions for actions on silo and tank structures that are not only associated with the stored particulate solids or liquids (e.g. the effects of thermal differentials) but substantially affected by them. NOTE Liquid loads on tanks are very precisely defined. Many loads on silos are not known with great precision. This document provides guidance for many practical situations for which very limited certain knowledge is available, and the information is derived from the limited experimental and analytical information available, coupled with conclusions drawn from failure investigations. The information is not based on a sound statistical treatment of experimental data. (3) This document is intended for use with concrete, steel, aluminium, timber and FRP storage structures. NOTE FRP is the standard acronym for fibre reinforced polymer materials. (4) This document is also applicable for the structural assessment of existing silos and tanks, unless otherwise specified by the relevant authority or, if not specified, agreed between the relevant parties for the specific project. NOTE 1 Changes in filling or discharge arrangements, changes in the wall friction of inner surfaces, or in the use of the silo, including storage of different particulate solids, can be reasons for assessing existing silos. NOTE 2 Differentiation of the liquid stored can be a reason for assessing existing tanks. 1.2 Assumptions (1) The assumptions of EN 1990-1 apply. (2) This document is intended to be used in conjunction with EN 1990 1, with the other parts of EN 1991, EN 1992, EN 1993, EN 1995, EN 1997, EN 1998 and EN 1999 where relevant to the design of silos and tanks. 1.3 Limitations on silos 1.3.1 Geometrical limitations (1) The following geometrical limitations apply to the design rules for silos and silo batteries (see 3.2.59 and 3.2.60) covered by this document: - the silo planform cross-section shapes are limited to those shown in Figure 1.1c. NOTE 1 Further information concerning planform cross-section geometries is given in Clause 7. NOTE 2 For the determination of the effective diameter dc of the silo see Figure 1.1c; - the following dimensional limitations on the aspect ratio for free-standing single cell silos hc/dc, the overall height hb and the effective diameter dc apply (see Figure 1.1): hc/dc < 10 (1.1) hb < 100 m (1.2) dc < 60 m (1.3) NOTE 3 See Figure 1.1 for hc, dc and hb. - the structural transition lies in a single horizontal plane (see Figure 1.1a). [Figure 1.1 - Silo forms showing dimensions and pressure notation] (2) Only hoppers that are conical (i.e. axisymmetric), rectangular pyramidal with a/b ≤ 1,5, wedge-shaped (i.e. with two vertical end walls on opposite sides) or oblique are covered by this document. Other hopper shapes and hoppers with internal structures require special considerations. (3) Silos with an oblique conical hopper used to achieve an eccentric outlet are covered by this document. (4) Silos with an oblique hopper are covered, but generally silos with a systematically non-symmetric geometry are not specifically covered by this document. These situations include a chisel hopper (i.e. a wedge hopper beneath a circular cylinder) and hoppers with an elongated outlet other than wedge shaped. 1.3.2 Limitations on the stored particulate solids (1) The following limitations on the stored particulate solids apply to the design rules for silos contained in this document: ...

Method of testing cement - Part 14: Determination of tricalcium silicate (C3S), dicalcium silicate (C2S), tricalcium aluminate (C3A) and tetracalcium aluminoferrite (C4AF) of common cement and clinker

This document describes the analytical procedures used to determine the content of tricalcium silicate (C3S), dicalcium silicate (C2S), tricalcium aluminate (C3A) and tetracalcium aluminoferrite (C4AF) of cement starting from a chemical analysis on cement. The method can be applied on all common cements as defined on EN 197-1. This document also describes the calculation procedures for determining of tricalcium silicate (C3S), dicalcium silicate (C2S), aluminate (C3A) and tetracalcium aluminoferrite (C4AF) in the Portland cement clinker as defined in the EN 197-1. In both cases, for cement and clinker, the calculation method is based on the Bogue method assuming each phase has a pure composition. This is a conventional method, whereby the actual mineralogical composition can differ from the results obtained using this method. For the determination of the various chemical species of clinker, cement and basic-complexing residue (BCR) described in this document, the method is indicated in the relevant clause.

Design of fans working in potentially explosive atmospheres

1.1 This document specifies the constructional requirements for fans constructed to Group II G (of explosion groups IIA, IIB and hydrogen) categories 1, 2 and 3, and Group II D categories 2 and 3, intended for use in explosive atmospheres. NOTE 1 Operation conditions for the different categories of fans used in this document are defined in Clause 4. 1.3 This document specifies requirements for design, construction, testing and marking of complete fan units intended for use in potentially explosive atmospheres in air containing gas, vapour, mist and/or dusts. Such atmospheres can exist inside (the conveyed atmosphere (flammable or not)), outside, or inside and outside of the fan. This document covers mechanical equipment, in particular fans. The “type of protection” as specified in EN ISO 80079 37:2016 is constructional safety. 1.4 This document is applicable to fans working in ambient atmospheres and with normal atmospheric conditions at the inlet, having — absolute pressures ranging from 0,8 bar to 1,1 bar, — and temperatures ranging from −20 °C to +60 °C, — and maximum volume fraction of 21 % oxygen content, — and an aerodynamic energy increase of less than 25 kJ/kg. NOTE 1 25 kJ/kg is equivalent to 30 kPa at inlet density of 1,2 kg/m3. This document can also be helpful for the design, construction, testing and marking of fans intended for use in atmospheres outside the validity range stated above or in cases where other material pairings need to be used. In this case, the ignition risk assessment, ignition protection provided, additional testing (if necessary), manufacturer's marking, technical documentation and instructions to the user, clearly demonstrate and indicate the equipment's suitability for the conditions the fan can encounter. NOTE 2 Temperatures below −20 °C can be considered. Material suitability can require specific evaluation for these temperatures. With lower temperature the explosion pressure increases, which leads to increased test pressures (see A.3) and can require specific testing. Although the standard atmospheric conditions in EN ISO 80079 36:2016 give a temperature range for the atmosphere of −20 °C to +60 °C the normal ambient temperature range for the equipment is −20 °C to +40 °C unless otherwise specified and marked. 1.5 This document does not apply to: — group I fans (fans for mining); — explosion group IIC (other than hydrogen); — category 1D fans; — cooling fans or impellers on rotating electrical machines; — cooling fans or impellers on internal combustion engines, vehicles or electric motors. NOTE 3 Measures for category 1D fans are given in EN 1127 1:2019. NOTE 4 Measures for explosion group IIC (other than hydrogen) are given in EN 1127 1:2019. NOTE 5 Measures for explosion group I are given in EN ISO/IEC 80079 38:2016 and EN 1127 2:2014.

Methods of testing cement - Part 16 - Sulfate resistance - Square prism method

This document describes a test method applicable to cast test specimens for evaluating the Sulfate Resistance (SR characteristic) of cements. Sulfate resistance means that these binders can be used in concrete bodies submitted to sulfate attacks. In these methods, the test is carried out under controlled exposure conditions using a defined concentration of sulfate solution. The chosen test conditions are intended to accelerate external sulfate attack. This test method is appropriate in particular for CEM III/A cements and other various binders, in particular those with pozzolanic main constituents. It is adapted from the CUR - NL - Civieltechnisch Centrum Uitvoering Research en Regelgeving (Centre for Civil Engineering Research and Codes) - Recommendation 48 - Suitability test for new cements for application in concrete. This test method is listed in European Assessment Document - EAD 150004-00-0301, Annex B.
